Black market exchange rates in India: an empirical analysis

In this paper, we explore the determinants of black market (BM) exchange rates in India using annual data from 1955–1994 and integration and cointegration analysis. Two important factors, namely the import capacity of official foreign exchange reserves and restrictions on international trade, have largely been ignored as determinants of BM rates. We stress the importance of these two factors and incorporate them, with others more familiar in the literature, in our theoretical and empirical model for BM rates in India. Our empirical findings show that a low level of official foreign exchange reserves negatively and a high level of trade restrictions positively affect BM rates. We show that the flexible Bretton Woods exchange rate policies for India in 1973 have a negative impact on BM rates. The results also reveal that interest rate policies positively affect BM rates. Thus, our empirical model lends support to the trade and monetary approaches to BM rates and hence, trade restrictions with excess money supply should be removed to eliminate the BMs for forex in India.

Monitoring Job Offer Decisions,Punishments, Exit to Work,and Job Quality

Unemployment insurance systems include the monitoring of unemployed workers and punitive sanctions if job search requirements are violated. We analyze the causal effect of sanctions on the ensuing job quality, notably on wages and occupational level. We use Swedish data and estimate duration models dealing with selection on unobservables. We also develop a theoretical job search model that monitors job offer rejection versus job search effort. The empirical results show that, after a sanction, the wage rate is lower and individuals move more often to a part‐time job and a lower occupational level, incurring human capital losses.     

BILATERAL MARKET STRUCTURES AND REGULATORY POLICIES IN INTERNATIONAL TELEPHONE MARKETS

We develop models of bilateral oligopoly with traffic exchanges to study the competition and regulatory policies in the international telephone markets. Under the requirement of uniform settlement rates, the proportional return rule (PRR) inflates the rates and hence neutralizes PRR's effect on calling prices. Retail competition and PRR increase net settlement payments. Market efficiency is improved when there are multiple channels for traffic exchanges. Using a panel of 47 countries that exchanged traffic with the United States between 1992 and 2004, we test the effects of bilateral market structures and the U.S. policies. The empirical results support our theoretical findings.     

BEAUTY PREMIUM AND MARRIAGE PREMIUM IN SEARCH EQUILIBRIUM: THEORY AND EMPIRICAL TEST

We propose a theoretical explanation for the so‐called beauty premium. Our approach relies entirely on search frictions and the fact that physical appearance plays an important role in attracting a marriage partner. We analyze the interaction between frictional labor and marriage markets, making use of what we label constrained job search. The optimal strategy entails different reservation wages for different men, and we establish the existence of a search equilibrium characterized by a beauty premium and/or marriage premium. Predicted profiles of premia allow for potential falsification tests and point to relevant empirical evidence in support of our theory.     

Trade,transport costs and trade imbalances: An empirical examination of international markets and backhauls

The US trade deficit has been growing for over 25 years and has been accompanied by enlarging freight rate differentials. While traditional models of trade have ignored these gaps assuming symmetry across all bilateral trade costs, the specific linkages between trade imbalances and international transportation costs have remained unexplored. Given the current trade policies, the implications arising from the endogenous adjustment of bilateral transport costs to policy-induced changes in the US trade deficit are of particular importance. To break new ground on this issue, we develop and estimate a model of international trade and transportation that accounts for the effects of persistent trade imbalances. The theoretical results are supported by our empirical analysis and indicate that bilateral transport costs adjust to a country's trade imbalance. The implication is that a unilateral import policy, for example, will cause spillover effects into the bilaterally integrated export market. To illustrate, we use our empirical results to simulate the anticipated spillover effect from the Chinese ban on waste imports. We find that China's ban and the projected 1.5% rise in the US trade deficit will lead to not only a 0.77% reduction of transport costs charged on US exports to China but also a 0.34% increase in transport costs on US imports from China.     

STRUCTURAL EMPIRICAL EVALUATION OF JOB SEARCH MONITORING

To evaluate search effort monitoring of unemployed workers, it is important to take account of post‐unemployment wages and job‐to‐job mobility. We structurally estimate a model with search channels, using a controlled trial in which monitoring is randomized. The data include registers and survey data on search behavior. We find that the opportunity to move to better‐paid jobs in employment reduces the extent to which monitoring induces substitution toward formal search channels in unemployment. Job mobility compensates for adverse long‐run effects of monitoring on wages. We examine counterfactual policies against moral hazard, like reemployment bonuses and changes of the benefits path.     

SPACE AND TIME: A COMPETING RISKS ANALYSIS OF THE IMPACT OF PROPERTY TAXES AND ZONING RESTRICTIONS ON RESIDENTIAL DEVELOPMENT

Property taxes and zoning restrictions are prevalent tools for managing land use. We combine microlevel data on residential subdivision development from the Baltimore, Maryland, metro area from 1994 to 2007 with a competing risks model to examine how both policies influence the density and timing of residential development. Consistent with theory, we demonstrate that the impact of both policies on optimal density and timing depends on whether density and time are substitutes or complements in the profit function. Our results have important implications as they provide key empirical insights into how property taxes and zoning interact to influence development patterns.     

The interaction between capital controls and exchange rate regimes: evidence from developing countries

Abstract

This paper provides an empirical analysis of the interaction between capital controls and exchange rate policies in developing countries in the 1980s and 1990s. We estimate a simultaneous-equations panel mixed logit model for the joint determination of two decisions. We find strong influences from de jure exchange rate regimes on capital account policies but somewhat weaker feedback impacts. With de facto exchange rate regimes the influences in both directions are similar to each other.     

Cross‐Subsidies,and the Elasticity of Informality to Social Expenditures: The Case of Mexico's Seguro Popular

How is the size of the informal sector affected when the distribution of social expenditures across formal and informal workers changes? How is it affected when the tax rate changes along with the generosity of these transfers? In our search model, taxes are levied on formal‐sector workers as a proportion of their wage. Transfers, in contrast, are lump‐sum and are received by both formal and informal workers. This implies that high‐wage formal workers subsidize low‐wage formal workers as well as informal workers. We calibrate the model to Mexico and perform counterfactuals. We find that the size of the informal sector is quite inelastic to changes in taxes and transfers. This is due to the presence of search frictions and to the cross‐subsidy in our model: for low‐wage formal jobs, a tax increase is roughly offset by an increase in benefits, leaving the unemployed approximately indifferent. Our results are consistent with the empirical evidence on the recent introduction of the “Seguro Popular” healthcare program.     

SOCIAL INVESTMENT AND YOUTH LABOR MARKET PARTICIPATION

In this paper, we first rely on small area techniques to derive from EU statistics on income and living conditions (EU‐SILC) survey new indicators of compensatory and social‐investment policies at regional level. While compensatory policies have mainly the goal of protecting individuals from “old” risks (e.g., old‐age), investment‐related social policies tend to focus more on “new social risks” (e.g., skill deficits). We rely on these new indicators to perform a data‐driven structural vector autoregressive (SVAR) analysis to investigate the causal relationships between youth labor market outcomes and these two types of spending. Our results support the view that social‐investment policies are effective for tackling new social challenges. (JEL C18, C54, E02)     

EQUILIBRIUM SEARCH AND TAX CREDIT REFORM

An empirical equilibrium job search model with wage posting is developed to analyze the impact of U.K. tax reforms. The model allows for a rich characterization of the labor market, with hours responses, accurate representations of the tax and transfer system, and both worker and firm heterogeneity. The British Working Families' Tax Credit and contemporaneous reforms are predicted to increase employment, with equilibrium effects found to be relatively modest. The model is used to assess the impact of alternative policies, with equilibrium effects shown to become important as the generosity of tax credits is increased.     

市场支持、产业互动与中国服务业发展

本文利用最新投入产出数据,分析了中国制造业和服务业互为中间投入的逻辑关系,进而揭示了两者之间的内生性,并从需求视角对中国供给导向型的服务业发展政策进行了反思。在构建联立方程的基础上,利用2000～2008年中国省级层面的面板数据进行了经验分析,得出的结论是:中国服务业作为高级要素投入促进了制造业发展,而以代工生产和加工贸易为主要特征的制造业并没有形成服务业发展的市场支持。由此得出的政策含义是:在制定服务业发展政策时,应考虑制造业对服务业发展的市场支持作用,进而形成产业互动的良性发展循环。     

Agri-Environmental Program Compliance in a Heterogeneous Landscape

Heterogeneity of agricultural landscapes may necessitate the use of spatially targeted instruments. But costly enforcement may be needed to ensure compliance with these policies. This paper examines the design of agri-environmental policies designed to achieve reductions in fertilizer application rates and installation of riparian buffers through the use of incentive-based instruments. We derive monitoring strategies capable of ensuring perfect compliance from risk neutral farmers given realistic limits on penalties for non-compliance. We then apply that framework empirically using a parametric model reflecting Finnish agricultural and environmental conditions. The results of our simulations indicate that subsidies for installing and maintaining buffer strips, used alone, are the most cost effective means of reducing nitrogen runoff from crop production. This policy is also the most attractive politically, in that it reduces farm income less than the alternatives considered.     

发展中国家汇率制度安排的名与实——对法定汇率制度与事实汇率制度之差异的经验分析

文章分析了发展中国家汇率制度安排名与实不符现象的分布与演变,并对其成因提出了一些假说。文章使用面板数据多元混合Logit模型的计量分析发现,较高的通货膨胀导致恐惧浮动现象,而较高外汇储备或严格的资本管制则导致恐惧固定现象,这在很大程度上支持了我们提出的关于发展中国家汇率制度安排名与实不符现象成因的假说。     

THE CORRELATION OF YOUTH PHYSICAL ACTIVITY WITH STATE POLICIES

Childhood overweight has risen dramatically in the United States during the past three decades. The search for policy solutions is limited by a lack of evidence regarding the effectiveness of state policies for increasing physical activity among youths. This paper estimates the correlation of student physical activity with a variety of state policies. We study nationwide data on high school students from the Youth Risk Behavior Surveillance System for 1999, 2001, and 2003 merged with data on state policies from several sources. We control for a variety of characteristics of states and students to mitigate bias due to the endogenous selection of policies, but we conservatively interpret our results as correlations, not causal impacts. Two policies are positively correlated with participation in physical education (PE) class for both boys and girls: a binding PE unit requirement and a state PE curriculum. We also find that state spending on parks and recreation is positively correlated with two measures of girls' overall physical activity. ( JEL I18, I28)     

EQUALITY AND EFFICIENCY: ANTIDISCRIMINATION POLICIES IN THE LABOR MARKET

Some have criticized government antidiscrimination programs for causing efficiency losses both by devoting public resources to monitoring and enforcement and by distorting personnel decisions. This paper examines the efficiency consequences of such programs when discrimination is caused by a market failure and when regulators are imperfectly informed about individual firms' personnel policies.
This paper outlines a simple model of "statistical discrimination" and shows that an equal opportunity rule, which constrains employers from offering different wage schedules to different groups, will improve the efficiency of this economy. Employers will attempt to evade such regulation, and the paper describes an evasion strategy in which employers search for worker "qualifications" that can act as proxies for race or sex. The paper discusses problems involved in monitoring and enforcing compliance, and considers two possible responses by the regulatory agency. The first is analogous to "disparate impact" judgments in which the type of information that employers can use in personnel decisions is regulated. The second is an affirmative action-type policy that monitors the outcomes, rather than the process, of hiring and compensation decisions. Affirmative action policies have some advantages since they permit employers to use information more efficiently than do policies that attempt to regulate personnel decisions directly. However, affirmative action policies are likely to lead to charges of preferential treatment.     

Relative price and inflation variability in a simple consumer search model

There is a large empirical literature on the effect of aggregate inflation on both price-level dispersion (relative price variability, RPV) and inflation rate dispersion (relative inflation variability, RIV) across goods or locations. Early empirical work of RIV has an explicit theoretical foundation in signal-extraction models. However, recent empirical work on RPV has produced results inconsistent with signal-extraction models. In particular, while RIV is increasing in the absolute value of inflation shocks, RPV is a negative monotonic function of inflation shocks. We show that consumer search theory offers a potential explanation for these apparently contradictory observations.     

Currency interdependence and dollarization

This paper constructs a search model of currency interdependence, and uses it to examine how in dollarized economies the foreign currency reacts to various shocks to the domestic currency. Currency interdependence is generated by allowing sellers to take into account their outside option of trading with the domestic currency while bargaining with buyers holding the foreign currency. The shocks consist in movements in the domestic interest rate, domestic inflation and the domestic currency’s market power. We show that if the purchasing power of the domestic currency is low, any shock that increases its value, such as a higher domestic interest rate, translates into a depreciation of the foreign currency. However, the result is opposite when the purchasing power of the domestic currency is high. We show that when money is indivisible these shocks can drive in or out the foreign currency. When money is divisible, this currency substitution effect is more limited. We use our results to discuss the opportunity of various de-dollarization policies and show that some can be counterproductive.     

OPTIMAL CONTRACTS FOR CENTRAL BANKERS AND PUBLIC DEBT POLICY*

We consider how the second‐best allocation corresponding to an optimal rule under the policy commitment of a central bank and a fiscal authority with a consolidated government budget constraint can be achieved, even though these authorities are unable to commit themselves to their optimal policies and ignore the strategic interaction between their policies. Our results show that the best practical institutional arrangement is to have an instrument‐independent central bank that controls the money supply to determine the rate of inflation and commits itself to an inflation target that depends on fiscal variables.     

The real exchange rate and economic development

Recent empirical studies have found a robust correlation between competitive exchange rates and economic growth in developing economies. This paper presents (i) a formal model to help explain these findings and (ii) econometric evidence on the relation between investment and the real exchange rate. The model emphasizes the existence of (hidden) unemployment as a source of endogenous growth, even under constant returns to scale. Growth promoting policies, however, affect the external balance, and two instruments are needed in order to achieve targets for both the growth rate and the trade balance. The real exchange rate can serve as one of those instruments. The implications of the model for the relation between real exchange rates and the rate of capital accumulation find support in our econometric analysis.
