Individual Transferable Quota Markets under Illegal Fishing

The use of individual transferable quotas in fisheries has been considered an opportunity to achieve a given total allowable catch with a maximum social benefit. One of the assumptions used in obtaining that result is that the system is in perfect compliance. The presence of violations and the need for enforcement of tradable property rights systems in fisheries has not received much attention in the literature. The incidents of non-compliance, however, may affect the performance of transferable property rights-based fisheries in unexplored ways. In this paper, we adapt previous literature on enforcing emissions trading programs to analyze a positive model of fisherman behavior that operates under a perfectly competitive individual transferable quota system, while recognizing the opportunities for violations of quota holdings, given incomplete enforcement. Considering a poorly enforced, individual transferable quota system we are able to obtain a number of implications for the current and future equilibrium of the quota market, the time paths of the fishery, and the proper design of a policy rule on total allowable catch (TAC).     

Government policy in the formal and informal sectors

The paper quantitatively investigates, in general equilibrium, the interaction between the firms' choice to operate in the formal or the informal sector and government policy on taxation and enforcement, given a level of regulation. A static version of Ghironi and Melitz's (2005) industry model is used to show that firms with lower productivity endogenously choose to operate in the informal sector. I use cross-country data on taxes, measures of informality, and measures of regulation (entry and compliance costs, red tape, etc.) to back out how high the enforcement levels must be country by country to make the theory match the data. The welfare gains from policy reforms are on average 1.2% (measured in terms of consumption) for OECD countries. I also find that the welfare gains from reducing regulation are on average 2.1%. Finally, performing a similar decomposition to that of Hall and Jones (1999), I find that distortions associated with informality account for a factor of 1.5 of the output per capita difference between the richest and the poorest countries.     

Tax collection,the informal sector,and productivity

An important determinant of informality in a country is its tax enforcement capacity, which some authors argue further distorts the decisions of firms and creates inefficiency. In this paper, I assess the quantitative effect of incomplete tax enforcement on aggregate output and productivity using a dynamic general equilibrium framework. I calibrate the model using data for Mexico, where the informal sector is large. I then investigate the effects of improving enforcement. I find that under complete enforcement, Mexico's labor productivity and output would be 19% higher under perfect competition and 34% higher under monopolistic competition. The source of this gain is the removal of the distortions induced by incomplete enforcement of taxes. These distortions affect the economy in three ways: by reducing the capital–labor ratios of informal establishments; by allowing low-productive entrepreneurs to enter; and by misallocating resources towards low-productive establishments. As a result, TFP and capital accumulation are reduced, and hence output. I decompose the gains following the guidelines of five leading papers in the literature of resource misallocation across plants. I isolate the effects of pure factor misallocation, distorted occupational choices, capital accumulation, and complementarities. I also study marginal improvements in enforcement and find that there is an inverted-U relationship between the size of the informal sector and output. This reflects the fact that improving enforcement entails a tradeoff: more taxes vs. fewer distortions.     

THE POLITICAL ECONOMY OF QUOTA RENTS IN A DYNAMIC INTERNATIONAL TRADE MODEL*

This paper considers the implications of allowing quota rents to become capitalized. Capitalized quota rents crowd out physical capital in savers’portfolios, reducing the capital stock. Capitalization of quota rents also makes removal of the quota politically more difficult, since those currently alive may not be able to fully compensate the losers before the losers die. I use an overlapping generations model to provide examples which illustrate the difficulty of removing a quota once its rents have been fully capitalized. This work has implications for any policy which could lead to capitalized rents.     

The Interaction of Legal and Social Norm Enforcement

Although legal sanctions are often nondeterrent, we frequently observe compliance with “mild laws.” A possible explanation is that the incentives to comply are shaped not only by legal, but also by social sanctions. This paper employs a novel experimental approach to study the link between legal and social norm enforcement. We analyze whether the two institutions are complements or substitutes. Our results show that legal sanctions partially crowd out social norm enforcement. Mild laws nevertheless give scope for a potentially large, positive welfare effect, as a higher level of compliance is achieved at lower social enforcement costs.     

Interaction of formal and informal financial markets in quasi-emerging market economies

The primary objective of this paper is to investigate the interaction of formal and informal financial markets and their impact on economic activity in quasi-emerging market economies. Using a four-sector dynamic stochastic general equilibrium model with asymmetric information in the formal financial sector, we come up with three fundamental findings. First, we demonstrate that formal and informal financial sector loans are complementary in the aggregate, suggesting that an increase in the use of formal financial sector credit creates additional productive capacity that requires more informal financial sector credit to maintain equilibrium. Second, it is shown that interest rates in the formal and informal financial sectors do not always change together in the same direction. We demonstrate that in some instances, interest rates in the two sectors change in diametrically opposed directions with the implication that the informal financial sector may frustrate monetary policy, the extent of which depends on the size of the informal financial sector. Thus, the larger the size of the informal financial sector the lower the likely impact of monetary policy on economic activity. Third, the model shows that the risk factor (probability of success) for both high and low risk borrowers plays an important role in determining the magnitude by which macroeconomic indicators respond to shocks.     

Market power and compliance with output quotas

This paper examines the compliance behaviour of a dominant firm in an output quota market when the firm is able to exercise market power in both the quota and the output markets. Provided the firm has an initial quota endowment which is strictly positive, under some circumstances the firm may find it profitable to comply or even over-comply in its quota demand, even in the absence of enforcement. The results are compared to those found in the pollution permit literature for a firm with market dominance only in the permit market, to which some additional observations are also added concerning efficiency outcomes under non-compliance.     

Order with Some Law: Complementarity versus Substitution of Formal and Informal Arrangements

While some argue that incomplete incentive contracts facilitatethe self-enforcement of informal dealings, other authors submitthat they substitute for or "crowd out" social norms supportinginformal arrangements. We use experimental evidence to testthese theories by manipulating the extent to which individualstransact repeatedly and the level of contract costs. We findthat, by enforcing contractible exchange dimensions, contractsfacilitate the self-enforcement of noncontractible dimensions.This complementarity effect is particularly important when repetitionis unlikely and thus self-enforcement is difficult. Althoughour data suggest the existence of reciprocity as an alternative,informal enforcement mechanism, we do not find evidence thatcontracts substitute for this social norm.

DIFFERENTIATING BETWEEN FIRST AND REPEAT OFFENSES

I present a model where a regulator monitors compliance with a policy by a population of individuals, some of whom repeatedly prefer to violate the policy, while others only occasionally want to experiment. I show that the regulator can use sanctions, contingent on past violations of the policy, to differentiate between the agents and to improve welfare. Such punishment plans arise frequently in practice. As a result, a regulator prefers investing in enforcement rather than use maximal sanctions. ( JEL K42, K14, L51)     

Discretionary enforcement and strategic interactions between enforcement agencies and firms: a theoretical and laboratory investigation

This paper presents a game theoretic morphological analysis of the strategic interactions between environmental enforcement authorities and polluting firms. The models explore the role of discretion that such authorities enjoy, either in deciding how to pursue environmental violations (investigative and prosecutorial discretion) or in judging them (judicial discretion). The purpose is to identify both the optimal firms’ behaviour in terms of compliance, and the enforcement authorities’ optimal strategies in terms of enforcement actions to undertake. Consistent with the setting of the game theoretic models, the role of the enforcement agencies in deterring firms from polluting is, then, empirically tested by means of laboratory experiments. Laboratory evidence on compliance behaviour of firms when faced with enforcement conditions predicted by the theoretical models set up is discussed for the different experimental treatments performed. Overall, we suggest that making environmental enforcement less predictable for the firms, and thus creating a degree of uncertainty for the violators, can actually encourage deterrence and, thus, improve compliance. Thus, a partly unpredictable enforcement strategy may generate more compliance than an environmental policy that is known with certainty in advance.     

Pigouvian Taxation in Tourism

The paper studies the characteristics and the effects of a tax imposed by a local government on the land used to create new tourists' accommodations. First, a dynamic policy game between a monopolist in a tourist area and a local government is considered. In each period the former has to decide the size of land undergoing development, whereas the latter has to choose the tax to levy on each newly developed area unit. Linear Perfect Markov strategies are derived for both the non-cooperative and the public monopoly case. In equilibrium, a public monopoly would develop land more rapidly than a private monopoly. Furthermore, the more the monopolist discounts the future, the more the long run use of the natural resource is reduced. Second, the properties of the tax are studied considering an oligopolistic market structure. The tax alone does not lead to the socially optimal level of land use. However, its combined effect with another policy instrument such as a quota, induces the optimal level of resource use.     

Tax compliance and firms' strategic interdependence

We focus on a relatively neglected area of the tax-compliance literature in economics, the behaviour of firms. We examine the impact of alternative audit rules on receipts from a tax on profits in the context of strategic interdependence of firms. The enforcement policy can have an effect on firms' behaviour in two dimensions — their market decisions as well as their compliance behaviour. An appropriate design of the enforcement policy can thus have a “double dividend” by manipulating firms in both dimensions.     

Property Rights, Renewable Resources and Economic Development

This paper analyzes the role of endogenous property rights in the development of an open resource-based economy. I incorporate renewable resources and endogenous decisions on property rights into a convex growth model with the formal and informal sectors. I find that along the transition path to steady state, property rights enforcement is not constant but improves with time as well as involves intermediate property rights specification (between open access and perfect property rights). International trade and labor market are driving these endogenous changes. Property rights improve with favorable terms of trade when the economy exports resource services and stronger property rights help maintain the resource stock by deterring illegal harvest. This pushes labor away from the informal harvest sector toward greater participation in the formal sector of the economy. In turn, more labor participation in the formal sector along with capital formation increase the country’s output and consumption. Overall, with an open economy and well-functioning institutions, renewable resources have a positive impact on economic growth.     

Price mimicking under cost-of-service regulation: the Swedish water sector

This study provides an empirical test of price mimicking among publicly owned water utilities. Using a fixed effects spatial Durbin model with data from Swedish municipalities during 2002–2012, I estimate the elasticity of the own relative to neighbors’ average price to 0.14. This behavior can be explained in terms of an informal yardstick competition: when consumers use neighboring municipalities’ prices as benchmarks for costs or as behaviorally based reference prices, policy makers will face the risk of consumer complaints and reduced voter support if deviating too much from neighboring municipalities’ prices. Further, I find some evidence that price mimicking is more pronounced in municipalities where voter support for the ruling coalition is weak.     

ENTRY AND IMPORT QUOTA

An import quota set stricter than the free trade level is quite common for the domestic entry protection. However, this paper shows that as the products are vertically differentiated, an import quota that is simply set at the original free trade level could be effective on entrant protection. This quota policy also improves both consumer surplus and total domestic welfare, which is in sharp contrast to the implications of existing literature. Our result suggests that an import quota has a stronger protection effect on domestic production if the domestic and foreign products are vertically differentiated.     

How should environmental policy respond to business cycles? Optimal policy under persistent productivity shocks

How should environmental policy respond to economic fluctuations caused by persistent productivity shocks? This paper answers that question using a dynamic stochastic general equilibrium real business cycle model that includes a pollution externality. I first estimate the relationship between the cyclical components of carbon dioxide emissions and US GDP and find it to be inelastic. Using this result to calibrate the model, I find that optimal policy allows carbon emissions to be procyclical: increasing during expansions and decreasing during recessions. However, optimal policy dampens the procyclicality of emissions compared to the unregulated case. A price effect from costlier abatement during booms outweighs an income effect of greater demand for clean air. I also model a decentralized economy, where government chooses an emissions tax or quantity restriction and firms and consumers respond. The optimal emissions tax rate and the optimal emissions quota are both procyclical: during recessions, the tax rate and the emissions quota both decrease.     

Entrepreneurship in the shadows

I develop a dynamic model of forward-looking entrepreneurs, who decide whether to operate in the formal economy or informal economy and choose how much to invest in their businesses, taking government policy as given. The government has access to two policy tools: taxes on formal business activity and enforcement (or policing) discouraging informality. The main focus of the paper is on transitional dynamics under different initial wealth levels. Whether an initially small business will be trapped in the informal economy and remain small forever or grow quickly and become a large formal business depends on tax and enforcement policies. High tax rates accompanied by loose enforcement – which is mostly the case in less-developed countries (LDCs) – induce tax avoidance, discourage investment in formal businesses, and drive the entrepreneurial activity towards the informal sector even though the initial wealth level is high. Lowering taxes on formal activity joined with strict enforcement can help reducing the magnitude of poverty traps in LDCs – such as the MENA region, Latin America and developing Asia.     

Do Protected Areas Reduce Forest Fragmentation? A Microlandscapes Approach

Conservation policies influence both the amount of habitat loss and patterns of habitat fragmentation. This paper develops a “microlandscapes” approach that combines fragmentation measures with quasi-experimental evaluation methods in order to assess the effects of policy on habitat fragmentation. As an application, the paper estimates whether and to what extent wildlife sanctuaries and national parks in Thailand prevented forest loss and fragmentation. I find that both types of protected areas significantly increased forest cover, average forest patch size and maximum forest patch size. Comparisons between the two types indicate that wildlife sanctuaries were more effective than national parks in terms of protecting forest in the interior versus exterior areas of parks and preventing fragmentation conditional on the level of forest cover. The differences are consistent with predicted differences resulting from spatial patterns of enforcement that are uniform or core-focused in the wildlife sanctuaries versus boundary-focused or include agglomeration penalties in the national parks. Given the greater effectiveness of wildlife sanctuaries in preventing fragmentation and the suggestive link to enforcement types, these results reinforce existing theoretical work urging conservation managers to consider how the spatial distribution of enforcement may affect patterns of resource use.     

Examining the effect of IMF conditionality on natural resource policy

Can International Monetary Fund (IMF) lending improve natural resource governance in borrowing countries? While most IMF agreements mandate policy reforms in exchange for financial support, compliance with these reforms is mixed at best. The natural resource sector should be no exception. After all, resource windfalls enable short-term increases in discretionary spending, and office-seeking politicians are often unwilling to forgo this discretion by reforming the oil, gas, or mining sector. I investigate how and when borrowers go against their political interests and establish natural resource funds—a tool often promoted by the IMF—in the wake of a loan agreement. Using text analysis, statistical models, and qualitative evidence from natural resource policy and IMF conditionality for 74 countries between 1980 and 2019, I show that borrowers under an IMF agreement are more likely to create or regulate a resource fund, particularly if the agreement includes binding conditions that highlight the salience of natural resource reforms. This study contributes to extant research by proposing a new method to extract information from IMF conditions, by introducing a novel dataset on country-level natural resource policy, and by identifying under what circumstances international reform efforts can help combat the resource curse.
