BECE 143 Solved Guess Paper 2026 is an 18-page PDF carrying 14 fully written answers for Environmental Economics, the Semester V discipline specific elective of the BAECH programme. It is not a question list. Every question in it already has a finished answer, written to the word limit the examiner expects, with the definition, the scholar's name and the list counts kept intact.
Environmental economics is the branch of economics that studies how market activity damages or protects natural resources, and what taxes, permits and property rights can do about it. In BECE-143 that idea is spread across six blocks, and the term-end paper picks from all six. That is exactly why a scattered revision hurts here more than in other economics electives.
1. What You Get in the BECE 143 Guess Paper 2026 for Environmental Economics
You get 14 solved questions across 18 pages: 5 long answers of 20 marks, 6 medium answers of 12 marks and 3 short notes of 6 marks, each tagged with its block and its likely section.
The file is arranged in exam order rather than book order. Section A material sits first, Section B next, Section C at the end, so the sequence you revise in is the sequence you will write in. Each question page also shows the sessions in which that topic last appeared, which tells you why it is in the paper at all.
Two extra pages sit at the back. One is a student instruction page covering the exam pattern, the topics worth skipping and the three habits examiners reward. The other is a frequency table for the last six papers. If you are buying across several courses this session, the full IGNOU Solved Guess Paper collection follows the same structure for every code.
What the file does not pretend to be: a question bank, a copy of the IGNOU textbook, or a leaked paper. It is a ranked shortlist with finished answers, and it is honest about the topics it has deliberately left out.
2. Sample Questions with Answers from the BECE 143 Solved Guess Paper
Five of the 14 answers are printed below in full, one from each of Blocks 1 to 5, covering all three mark weights. Read one completely before deciding anything. The remaining 9 answers, including the Block 6 questions on the Environmental Kuznets Curve and on weak versus strong sustainability, are in the paid file.
Public Goods and Their Efficient Provision
Question: Define public goods. Explain the conditions under which the efficient provision of a public good is possible.
Meaning of public goods
Pure public goods are non-rival and non-excludable. Both properties have to hold together before a good qualifies, and sunlight is the standard textbook illustration of the pair.
Defining properties
- Non-rivalry: consumption by one agent does not reduce the amount available to another, so the marginal cost of serving one extra user is zero.
- Non-excludability: no agent can be kept out, so price cannot work as a rationing device.
Classification of goods
| Type | Excludable | Non-excludable |
|---|---|---|
| Rival | Private good, for example chocolate | Open access resource, for example a common fishery |
| Non-rival | Club or congestible good, for example a tolled road | Pure public good, for example national defence or sunlight |
Conditions for efficient provision
- Sum of willingness to pay rule: the good should be provided publicly when the sum of every agent's willingness to pay exceeds the total cost of providing it.
- Lindahl equilibrium: when aggregate willingness to pay exactly equals the budget needed for the facility, the ideal position is reached and no factor causes inefficiency.
- Free riding caveat: because the good is non-excludable, consumers understate their willingness to pay and enjoy it anyway, so actual contributions fall short of the efficient level.
Conclusion: a public good is efficiently provided only when the community's combined willingness to pay covers its cost, and non-excludability usually forces government intervention to reach that point.
Global Commons and Transboundary Pollution
Question: Discuss the concept of global commons and the complexities involved in addressing the pollution effects in the global commons.
Meaning
Transboundary pollution is pollution that is not confined within national boundaries but travels across them. A commons is land or water owned or used jointly by a community, and the global commons are the parts of the earth beyond national jurisdiction: the open ocean, the living resources in it and the atmosphere, with Antarctica as the only landmass treated this way.
Forms of transboundary pollution
- Unilateral spillover: pollution travels from one nation to another in a single direction.
- Bilateral spillover: pollution travels from one nation to another and back again.
- Multilateral spillover: pollution spreads among several nations in different directions, and global pollution is the special multilateral case.
Complexities in addressing the problem
- Weak property rights: non-excludability exposes the commons to the tragedy of the commons through overuse, congestion and degradation.
- No polluter pays statute: international law carries no polluter pays doctrine, so recovering compensation for cross-border damage, as in the Rhine river disaster, is extremely hard.
- No legal precedent: with little litigation history between states, disputes move slowly through negotiation and treaties.
- Need for consensus: solutions work only when all nations share responsibility, and conventions often fail because consensus varies across countries.
Conclusion: the global commons suffer chronic negative externalities under weak property rights, and without a polluter pays statute or precedent only genuine international cooperation can address transboundary pollution.
Pigouvian Tax and Pollution Fees
Question: What is a Pigouvian tax or pollution fee? Explain how it works in controlling environmental pollution.
Meaning of the Pigouvian tax
A pollution fee is the payment made per unit of pollution emitted by the polluter to a regulatory body, an idea traced to Arthur C. Pigou in 1920. Firms pollute because they are not held accountable for the social damage they cause. The practical application of pricing pollution was developed later by the environmental economist Alan Kneese in 1962.
How the tax works
- Incentive to abate: a fee per unit of emission makes lower emissions cheaper, so cutting pollution becomes the polluter's own interest rather than an imposed duty.
- Two instruments: the government can levy a per unit emission fee, or equivalently subsidise each unit of emission the firm abates.
- Cost minimisation: total pollution cost is abatement cost plus the fee, and the firm minimises the sum where the marginal saving from one more unit of emission equals the fee.
- Equilibrium condition: at the optimum the fee equals the negative of marginal abatement cost, so the marginal saving curve slopes downward against the price per unit of emission.
Conclusion: a Pigouvian tax internalises the external cost of pollution by pricing each unit emitted, pushing firms to abate until marginal abatement cost equals the fee.
Kaldor-Hicks Compensation Criterion
Question: Explain the Kaldor-Hicks compensation criterion. What is its main limitation?
Meaning
The Kaldor-Hicks compensation test checks whether total social benefits exceed total social costs. Also called the compensation principle, it is the foundation on which cost-benefit analysis in policy evaluation rests.
How the criterion works
- Potential improvement: a change is welfare improving as long as the winners could, in principle, fully compensate the losers and still be better off.
- Hypothetical transfer: the transfer need not actually happen; even hypothetically it leaves everyone at least as well off, giving a potential Pareto improvement.
- Contrast with Pareto: the Pareto criterion, proposed by Vilfredo Pareto, needs at least one gainer and no loser, which is too restrictive because most real policies create both.
Main limitation
Fairness is left unaddressed. The compensation is only potential and is rarely paid, so the losers can remain genuinely worse off while the policy still passes the test.
Conclusion: Kaldor-Hicks calls a change desirable when gains exceed losses so that winners could compensate losers, and its key weakness is that this compensation stays hypothetical.
Green National Accounts
Question: Write a short note on Green National Accounts.
- Why it is needed: the conventional System of National Accounts ignored depletion of natural resources while estimating GDP or GNP, leaving national income overstated.
- Natural capital: there is now global consensus on treating environmental resources as natural capital at par with physical capital, so additions and depletions enter the national income equation.
- SEEA approach: green accounting is operationalised through the System of Environmental-Economic Accounting, which adjusts national income for environmental change.
Conclusion: green national accounting corrects the conventional accounts by valuing resource depletion, giving a sustainability adjusted measure of national income.
That is 5 answers out of 14. The 9 that remain include Environmental Acts in India after 2000, negative externalities, the EKC hypothesis, the Coase theorem, the command and control approach, the displacement versus pollution haven comparison, use-value versus non-use-value, weak versus strong sustainability, and the materials balance model.
3. BECE 143 Environmental Economics Exam Pattern and Marks Distribution
The BECE-143 term-end paper is 100 marks in 3 hours, split into Section A (any 2 of 4 questions, 20 marks each), Section B (any 4 of 7 questions, 12 marks each) and Section C (short notes on any 2 of 4, 6 marks each).
| Section | Choice | Marks | Word limit | What it demands |
|---|---|---|---|---|
| Section A | Any 2 out of 4 | 2 x 20 = 40 | About 600 words | Full essay with definition, classification, diagram where relevant and a critical close |
| Section B | Any 4 out of 7 | 4 x 12 = 48 | About 350 words | Tight analytical answer, usually a comparison, a mechanism or a list of limitations |
| Section C | Any 2 out of 4 short notes | 2 x 6 = 12 | 100 to 150 words | Recall of a single concept with its definition and two or three supporting points |
Section B is where the paper is actually won. It carries 48 marks, more than Section A, yet most students spend their preparation time on long answers only. Four clean 350-word answers are easier to finish inside three hours than two sprawling essays, and the guess paper reflects that by giving Section B the largest share of its 14 questions.
You can confirm the structure yourself on the official IGNOU question paper archive, for example the BECE-143 June 2023 term-end paper published by IGNOU.
4. Block and Unit Structure of BECE 143 Environmental Economics
BECE-143 has 6 blocks and 14 units, running from the economy and environment linkage in Unit 1 to growth and the Environmental Kuznets Curve in Unit 14. The table below lists every unit with the concepts the examiner actually pulls from it.

Blocks 2, 3 and 6 between them supply most of the marks, which is why they hold the largest share of questions in the paper. The official unit PDFs are hosted on eGyanKosh, and our own unit summaries sit in the BECE 143 Study Material section if you want the concepts before the answers.
5. How This BECE 143 Guess Paper Was Built from Previous Year Question Papers
Six term-end papers, June 2023 through December 2025, were read question by question, every question was tagged to its block and section, and the topics were then ranked by how often they came back.
Three signals decided which 14 questions made the file. The first is raw repetition: environmental policy in India has surfaced in all six papers, so it sits at position one. The second is section stability, meaning a topic that keeps appearing in the same section can be prepared at a fixed length. The third is the recent gap, where a high frequency topic has skipped two consecutive sessions and is statistically due.
The answers were then written from the IGNOU blocks themselves, not paraphrased from coaching notes. Definitions, scholar names, dates such as Pigou in 1920 and Grossman and Krueger in 1991, and list counts such as the four EKC explanations were all kept as the book states them. Where a diagram carries marks, the answer says so instead of skipping it.
If you want to run the same check yourself before trusting the ranking, the past papers are worth twenty minutes of your time. Our IGNOU Previous Year Question Paper archive keeps them session-wise for this code.
6. BECE 143 Important Questions Ranked by Repeat Frequency
Environmental policy in India appeared in all six papers analysed, global commons in five, and public goods in four, which is why these three sit at the top of the file.
| Topic | Source unit | Appearances in 6 papers | Section it usually sits in | Priority |
|---|---|---|---|---|
| Environmental policy and Acts in India | Unit 7 | 6 of 6 | Section A | High |
| Global commons and transboundary pollution | Unit 8 | 5 of 6 | Section A | High |
| Public goods and efficient provision | Unit 3 | 4 of 6 | Section A | High |
| Environmental regulations, rationale and types | Unit 5 | 4 of 6 | Section B | High |
| Negative externalities in consumption and production | Unit 3 | 3 of 6 | Section A | High |
| Coase theorem and Coasian bargaining | Unit 4 | 3 of 6 | Section B | High |
| Environmental Kuznets Curve | Unit 14 | 3 of 6 | Section A | High |
| Tradable emission permits | Unit 6 | 3 of 6 | Section B or C | High |
| Valuation methods, hedonic, travel cost and contingent | Unit 11 | 3 of 6 | Section B | High |
| Weak and strong sustainability | Unit 13 | 3 of 6 | Section C | High |
| Pigouvian tax and pollution fees | Unit 6 | 3 of 6 | Section B | High |
| Pollution haven and displacement hypothesis | Unit 9 | 3 of 6 | Section B | High |
| Use-value against non-use-value | Unit 10 | 3 of 6 | Section B | Medium |
| Green accounting and national income measurement | Unit 12 | 3 of 6 | Section C | Medium |
| Kaldor-Hicks compensation criterion | Unit 2 | 2 of 6 | Section B | Medium |
| Materials balance model and thermodynamics | Unit 1 | 2 of 6 | Section A or C | Medium |
| Kyoto, Paris and global agreements | Unit 8 | 1 of 6 | Section C | Low |
Read the low priority row honestly. It is there so that you skip it, not so that you cover it. Spending an evening on Kyoto sub-clauses while the Coase theorem sits half understood is the most common way students lose 12 marks in this paper.
7. Assignment and Practical File Position in BECE 143 Environmental Economics
BECE-143 has no practical file, no lab record and no project component. It is a fully theoretical elective, so the only submission alongside the term-end paper is the tutor marked assignment.
Students search for a practical file index for this code because sister courses in the BAECH structure do carry project work. For BECE-143 the answer is simply that the index does not exist, and nobody should be selling you one. What does exist is the TMA, and its shape mirrors the exam closely.
| Component | Exists for BECE-143 | What it involves |
|---|---|---|
| Term-end examination | Yes | 100 marks in 3 hours across Sections A, B and C, held in the June and December sessions |
| Tutor marked assignment | Yes | Long, medium and short answer sections issued session-wise, submitted to the study centre before the exam form deadline |
| Practical file or lab record | No | Not part of this course, there is no laboratory or field component to record |
| Project or dissertation | No | Not applicable, the project requirement in BAECH sits with other courses, not with this elective |
| Viva voce | No | Not conducted for BECE-143 |
One practical consequence for revision: because there is no file to pad your score, the written paper carries the full weight of your result in this course. That makes the 48 marks sitting in Section B the single most valuable stretch of the syllabus.
8. Who This BECE 143 Guess Paper Is For
It suits BAECH Semester V students with two to three weeks left, students repeating a back paper, and working students who cannot read six blocks end to end.
It is genuinely not for everyone. If your exam is four months away, read the blocks properly and come back later. If you are aiming for a distinction in economics honours, treat the 14 answers as your revision spine and still read Units 10 and 11 in full, because valuation methods reward depth that no guess paper can compress.
Repeaters get the most out of it. A back paper attempt usually fails on coverage rather than understanding, and a ranked shortlist fixes coverage fastest. Students preparing several papers this session often pick up the wider BAECH Guess Paper set together, since the same ranking method is applied to every course in the programme.
9. How to Revise BECE 143 Important Questions in the Final Ten Days
Ten days is enough for BECE-143 if you give six days to the 14 answers, two days to writing practice against the clock, and two days to a second pass on definitions only.
- Days 1 and 2, Blocks 2 and 3: market failure, public goods, the Coase theorem, command and control, Pigouvian tax and tradable permits. This is the densest scoring zone in the paper.
- Days 3 and 4, Blocks 4 and 6: global commons, transboundary spillovers, pollution haven against displacement, the EKC and the two sustainability positions.
- Days 5 and 6, Blocks 1 and 5: thermodynamics and the materials balance model, Kaldor-Hicks, total economic value, valuation methods and green accounting.
- Day 7, diagrams only: draw the externality divergence, the Pigouvian fee equilibrium and the inverted U of the EKC until each takes under two minutes.
- Day 8, full mock: two Section A answers, four Section B answers and two short notes in three hours, handwritten, no notes open.
- Days 9 and 10, definitions and names: Pigou 1920, Kneese 1962, Grossman and Krueger 1991, Copeland and Taylor 2004, Kneese, Ayres and D'Arge 1970. These sentences open your answers and set the examiner's first impression.
One rule worth keeping through all ten days: never write a Section B answer longer than a page and a half. Examiners mark against a 350-word expectation, and an overlong answer costs you the time you needed for the fourth one.

11. BECE 143 Environmental Economics Guess Paper FAQs
What is included in the BECE 143 Solved Guess Paper 2026?
It includes 14 fully solved questions across 18 pages, covering all six blocks of Environmental Economics. Five answers carry 20 marks, six carry 12 marks and three are 6-mark short notes. Each question shows its block, its usual section and the sessions in which it last appeared, plus a student instruction page and a six-session frequency table at the back.
Is the BECE 143 guess paper useful for the December 2026 term-end exam?
Yes. The file was prepared for the 2026 term-end sessions of BECE-143, and December 2026 is the session still ahead. The ranking behind it comes from six papers held between June 2023 and December 2025, and because IGNOU rotates the same core concepts across sessions, the shortlist stays valid for the December attempt.
How many questions from the BECE 143 guess paper can I read before buying?
Five complete answers are printed on this page, one drawn from each of Blocks 1 to 5, and they cover all three mark weights. Nothing is truncated or blurred. The remaining nine answers, including both Block 6 questions, come with the paid file. Judge the writing quality from the samples before spending anything.
Does BECE 143 Environmental Economics have a practical file or project?
No. BECE-143 is a theory-only discipline specific elective with no practical file, no lab record, no project and no viva. The only submission besides the term-end paper is the tutor marked assignment issued for your session. Anyone selling a BECE-143 practical file index is selling something the course does not contain.
What is the exam pattern for BECE 143 Environmental Economics?
The paper runs 100 marks in three hours. Section A asks for any two of four questions at 20 marks each in about 600 words. Section B asks for any four of seven at 12 marks each in about 350 words. Section C asks for short notes on any two of four at 6 marks each, in 100 to 150 words.
Which BECE 143 important questions repeat most often in IGNOU papers?
Environmental policy and the Acts introduced in India after 2000 appeared in all six papers analysed. Global commons and transboundary pollution appeared in five. Public goods, efficient provision and the rationale for environmental regulation each appeared in four. These four topics alone can cover one Section A answer and two Section B answers.
Can the BECE 143 guess paper replace the IGNOU BECE-143 blocks?
No, and it is not built to. It compresses six blocks into the questions most likely to be asked, which is a revision tool rather than a substitute for study material. Students aiming for high marks should still read Units 10 and 11 on valuation, because those questions reward depth that a shortlist cannot carry.
How do I receive the BECE 143 guess paper after contacting you?
Send the course code BECE-143 to 9899436384 on WhatsApp and confirm which session you are appearing in. The complete 18-page PDF is shared on the same chat, readable on a phone or printable. Doubt support continues on that number until your paper is over, which helps most with the diagram based questions.
Is this BECE 143 guess paper an official IGNOU publication?
No. This is a study aid prepared independently by Unnati Educations and is not published, endorsed or authorised by the Indira Gandhi National Open University. The answers are written from the official BECE-143 blocks, and the exam pattern shown here is verified against IGNOU term-end question papers, but the file itself is ours.
