Implementing Market Access

This paper examines ex post subsidies as a means of enforcing market share targets. Subsidies set after firms make their strategic decisions are shown to create powerful incentives for firms to raise prices. These effects are stronger when targets, and hence subsidies, are specified on a firm-specific rather than industry-wide basis. This occurs because firms perceive themselves as subject to more competition (i.e., more elastic demand) in the latter case.     

A note on closing the windows: Some lessons from queuing theory

Consider two departments of a government each serving customers of a particular type. We explore conditions under which a reorganization leading to both departments serving both types of customers leads to an enhancement of "efficiency" defined in terms of the expected queue size in a stochstic equilibrium.     

Trade policy with endogenous entry revisited

This paper revisits the effects of tariffs and quotas in a competitive setting where three results are thought to hold. These are: that quotas are equivalent to specific tariffs, the form of tariffs—specific or ad valorem—does not matter, and that the way in which a quota is allocated has no real effects as it only affects the allocation of rents, not their size. We show that all three of these results are false when entry/exit is endogenous. Equivalence holds only if the initial level of entry is set at the long-run level under the quota.     

A Political‐Economic Account of Global Tariffs

The objective of this paper is to evaluate the relative importance of three distinct factors that motivate redistributive government policy: tariff revenues, consumer welfare, and producer profits. We generalize Grossman and Helpman's (1994, American Economic Review 84: 833–850). protection‐for‐sale model by positing that government places different weights on these components of the welfare of its polity when it decides which industries to protect and to what extent. Employing tariff data from 40 countries, the predictions from this model are used to estimate these weights. The results are surprising in their range and variety. Developing countries with weak tax systems often weigh tariff revenue heavily, while more developed countries weigh producer interests the most. Very few hold consumer welfare dear.     

Using spectral analysis and multinomial logit regression to explain households’ choice patterns

Many methods are available to analyze rank-ordered data. We used spectral analysis to identify the most preferred option of Formosan subterranean termites (FSTs) control as ranked by Louisiana homeowners. Respondents were asked to rank four termite control methods from the most preferred option to the least preferred option. Spectral analysis of complete ranked data indicated that the most preferred FST control choice is a relatively cheap ($0.13/square foot) option of a liquid treatment. Similarly, analysis indicated that liquid and bait treatments are the two most desired control choices. Multinomial logit analysis indicated that survey location, household pre-tax income, and knowledge of FSTs determined Louisiana homeowners’ ranking pattern choices.     

On necessarily welfare-enhancing free trade areas

The well-known Kemp-Vanek-Ohyama-Wan proposition establishes that if two or more countries form a customs union (CU) by freezing their net external trade vector through a common external tariff and eliminating internal trade barriers, the union as a whole and the rest of the world cannot be worse off than before. Owing to the fact that a Free Trade Area (whose member countries impose country specific external tariff vectors) does not equalize marginal rates of substitution across its member countries (in contrast to a CU), the literature has been unable to provide a parallel demonstration regarding welfare improving Free Trade Areas (FTAs). The present paper eliminates this gap. In extending the result to the case with intermediate inputs, the paper also sheds new light on the rules of origin required to support such necessarily welfare enhancing FTAs. We show here that provided no trade deflection is permitted, all that is required by way of rules of origin is that the goods produced within the union - whether final or intermediate - be allowed to be traded freely. The proportion of domestic value added in final goods does not enter as a criterion in the rules of origin.     

Contracting for information under imperfect commitment

We study optimal contracting under imperfect commitment in a model with an uninformed principal and an informed agent. The principal can commit to pay the agent for his advice but retains decision‐making authority. Under an optimal contract, the principal should (i) never induce the agent to fully reveal what he knows—even though this is feasible—and (ii) never pay the agent for imprecise information. We compare optimal contracts under imperfect commitment to those under full commitment as well as to delegation schemes. We find that gains from contracting are greatest when the divergence in the preferences of the principal and the agent is moderate.     

State and the software: public policies in the shaping of the Indian software sector

This paper attempts to argue that the emergence of a diverse and dominant software (SW) services industry in India is facilitated to a large extent by the range of policies and initiatives undertaken by the Indian State. In addition to a series of sector-specific policy initiatives and promotional schemes, the positive interplay among the trade, technological and tariff policies did contribute to the emergence of the SW services sector. The authors also argue that the overall liberalisation project initiated in the early 1990s, by way of initiating a distinct export orientation to economic thinking, did contribute to the sector's emergence.     

A New Approach to Human Development Index

Human development Index (HDI) was introduced by the United Nations Development Programme (UNDP) in 1990. For the first four years UNDP used the maximum and the minimum values of the data series to standardize the variables. In 1994 the procedure of standardization was modified with the introduction of arbitrary fixed minimum and maximum values for each variable. Both methods have merits and demerits. The present study proposes an alternative measure of estimating HDI which bridges the gap between the methods of computing HDI proposed by the UNDP in 1990 and 1994. This study also incorporates unadjusted per capita real gross domestic product (PCRGDP) instead of adjusted PCRGDP used by the UNDP. The data from the Human Development Report (HDR) 2000 for 174 countries are used to test the robustness of the suggested index and the results are compared to those of the HDI. Also average values for full sample as well as top 20 percent and bottom 20 percent are offered to show the superiority of our method to that of the UNDP's HDI.
