Causes of Growth and Decline in Mexico’s Maquiladora Apparel Sector

Under the North American Free Trade Agreement (NAFTA) beginning in 1994, the maquiladora sector was the dynamic manufacturing sector in Mexico, and its apparel subsector was especially so, more than quadrupling in employment from December 1993 to July 2000. Yet NAFTA’s influence on apparel employment is hard to find in a careful time series econometric analysis. Instead, much of employment growth is explained for 1980 to the present by changes in US demand as measured by real US gross domestic product or by real US apparel spending, by US/Mexico relative labor cost as proxied by the real peso‐dollar exchange rate, and by the relaxation of quotas on US apparel imports from Mexico in 1988–1990. In equations including these variables, tests for a structural break at the time of NAFTA find an effect which is either insignificant or else quite small and in some models negative. Possible explanations for this surprising result are discussed, along with the implications for cost–benefit analysis of free trade agreements.     

Exchange Rate Regimes and Welfare Losses from Foreign Crises: The Impact of the US Financial Crisis on Mexico

We modify the Gali and Monacelli small open economy dynamic stochastic general equilibrium (DSGE) model, calibrate to Mexican data and simulate the impact of the financial crisis on Mexico, under floating and counter factual fixed exchange rates. The floating exchange rate ameliorates welfare losses for Mexico. They are greater under fixed exchange rates because the return paths to equilibrium are more volatile (higher variance) and output, consumption and employment impulse response functions (IRFs) overshoot. Monetary policy, inflation targeting with floating exchange rates, clearly reduced the welfare costs vis‐à‐vis other counter factual policies including consumer price index‐based Taylor rule, domestic inflation Taylor rule and fixed exchange rates.     

Mexico in the 1990s: The Main Cross-Sectional Facts

This paper describes the main cross-sectional facts on individual and household earnings, labor supply, income, consumption and wealth in Mexico in the decade of the 1990s. We use two different data sources: the Mexican Employment Survey (ENEU) and the Mexican Income and Expenditure Survey (ENIGH). The contribution of this paper is twofold. First, we integrate the two surveys to provide a complete characterization of the changes in employment, wages, income, consumption and wealth in the 1990s. Second, we highlight some distinctive features that characterize the Mexican economy in this decade. In particular, we focus on the changes in the size of the informal sector and we study the relationship between changes in informality and changes in wage inequality.     

The “Dark Side” of Deregulation: How Competition Affects the Size of the Shadow Economy

This paper builds a theory that explains the dramatic expansion of the underground economy in the late 1990s by the sharp increase in market competition worldwide. I model an oligopoly game where firms first decide on entry and sector, and then compete in price. Operating in the underground sector reduces variable costs, but comes at the risk of being detected and fined. As competition intensifies (i.e., as consumers become more and more price‐sensitive), underground firms attract more demand, thus stealing business and profits from official firms. As a consequence, more firms enter the underground economy. A lenient policy toward the underground economy may increase welfare when markups are high, but will be welfare‐detrimental when markups are low.     

Emigration and wages in source countries: Evidence from Mexico

This paper examines empirically the effect of Mexican emigration to the United States on wages in Mexico using data from the Mexican and US censuses from 1970 to 2000. The main result in the paper is that emigration has a strong and positive effect on Mexican wages. There is also evidence for increasing wage inequality in Mexico due to emigration. Simple welfare calculations based on a labor demand–supply framework suggest that the aggregate welfare loss to Mexico due to emigration is small. However, there is a significant distributional impact between labor and other factors.     

Medical innovation and its diffusion: Implications for economic performance and welfare

We study the impact on economic performance and welfare of medical innovations and their endogenous diffusion. We construct a general equilibrium model with a medical sector and overlapping generations subject to endogenous mortality and calibrate it to reflect the development of the US economy and health care over the cardiac revolution during the 1980s and 1990s. By counterfactual analysis we find that (i) medical innovations have increased welfare without compromising GDP growth; (ii) there is a sizeable welfare loss due to the adoption lag involved with imperfect diffusion; and (iii) there is scope for Pareto improvement by way of subsidization of innovative health care.     

Real Minimum Wage and Growth Theory: Simulations and Some Policy Results

Abstract

A Solow type two‐sector growth model is used to examine several issues related to growth and unemployment in a minimum wage economy. By simulating the model, we demonstrate that given the same percentage increase in wage rate, an economy with a higher capital–labor ratio is more likely to decay. More importantly, a tariff policy reduces the unemployment periods by 92% provided that the current capital–labor ratio is one‐sixth of that of the steady state capital–labor ratio. We assume that the first best policy of uniform wage subsidy is not politically feasible.     

MONETARY POLICY DURING JAPAN'S LOST DECADE*

We develop a quantitative costly price adjustment model with capital formation for the Japanese economy. The model respects the zero interest rate bound and is calibrated to reproduce the nominal and real facts from the 1990s. We use the model to investigate the properties of alternative monetary policies during this period. The setting of the long‐run nominal interest rate in a Taylor rule is much more important for avoiding the zero bound than the setting of the reaction coefficients. A long‐run interest rate target of 2.3% during the 1990s avoids the zero bound and enhances welfare.     

North–South Trade Liberalization and Economic Welfare

We consider a general equilibrium model of a developing economy (the South) that opens to trade with a developed economy (the North). The southern economy is characterized by open urban unemployment and rural–urban migration, a competitive agricultural sector and a monopolistically competitive manufacturing sector. Hence, there is potential for both inter‐ and intra‐industry trade to arise on liberalization, in addition to distortionary effects of duality. Southern comparative advantage in agriculture may arise from the labor market distortion and the basis for intra‐industry trade is love for variety. We characterize various configurations of the trade pattern, and the resulting welfare consequences of opening to trade in this context. We illustrate a new mechanism under which in some circumstances it may be possible for trade liberalization to lower economic welfare in the South.     

The Financial Resource Curse*

In this paper, we present a model of the financial resource curse (i.e., episodes of abundant access to foreign capital coupled with weak productivity growth). We study a two‐sector (i.e., tradable and non‐tradable) small open economy. The tradable sector is the engine of growth, and productivity growth is increasing with the amount of labor employed by firms in the tradable sector. A period of large capital inflows, triggered by a fall in the interest rate, is associated with a consumption boom. While the increase in tradable consumption is financed through foreign borrowing, the increase in non‐tradable consumption requires a shift of productive resources toward the non‐tradable sector at the expenses of the tradable sector. The result is stagnant productivity growth. We show that capital controls can be welfare‐enhancing and can be used as a second‐best policy tool to mitigate the misallocation of resources during an episode of financial resource curse.     

Environmental Protection and Urban Unemployment: Environmental Policy Reform in a Polluted Dualistic Economy

This paper explores sufficient conditions for the welfare‐improving environmental policy reform in the Harris–Todaro economy. A rise in the pollution tax rate in the urban manufacturing has spillover effects on the two labor market distortions: the less‐than‐optimal manufacturing employment and the urban unemployment. If both are weakened the welfare improves. Otherwise, we need to develop an alternative sufficient condition. It is shown that there exists a range of welfare‐improving pollution tax rates, and that it corresponds to the lower values of tax rate. This range may shrink by the wage subsidy policy and the technological change toward less pollution‐intensive techniques.     

ASSESSING THE IMPACTS OF LABOR MARKET AND DETERRENCE VARIABLES ON CRIME RATES IN MEXICO

Many studies examine the relationship between crime rates and various economic and/or sociodemographic variables in high income countries, but similar efforts for middle and low income countries are less common. Utilizing an 8‐year panel data sample for all 32 states in Mexico, this study assesses the impact of Mexican labor market and deterrence variables on various Mexican crime rates. The principal results indicate that: (1) State gross domestic product (GDP) per capita has ambiguous effect on crime rates under different conditions. Both wages and unemployment rates are negatively linked with crime rates. (2) Although the Mexican judicial and public security systems are widely believed to be ineffective, increased federal police forces and incarceration rates are associated with lower crime rates, but higher public security expenditure per capita is associated with higher crime rates. (3) The impacts from labor market and deterrence variables presented in (1) and (2) continue to hold under the Fox administration as well as for non‐border states. Their respective impacts diminish, however, under the Calderon administration as well as for border states because of the small number of observations. Overall, the results indicate that increasing average wages, federal police forces, and incarceration rates would have significant impacts on reducing crime rates in Mexican states.

Informal self-employment and macroeconomic fluctuations

Informal self-employment is a major source of employment in developing countries. Its cyclical behavior is important to our understanding of the functioning of LDC labor markets, but turns out to be surprisingly complex. We develop a flexible model with two sectors: a formal salaried (tradable) sector that may be affected by wage rigidities, and an informal (non tradable) self-employment sector faced with liquidity constraints to entry. This labor market is then embedded in a standard small economy macro model. We show that different types of shocks interact with different institutional contexts to produce distinct patterns of comovement between key variables of the model: relative salaried/self-employed incomes, relative salaried/self-employed sector sizes and the real exchange rate. Model predictions are then tested empirically for Argentina, Brazil, Colombia and Mexico. We confirm episodes where the expansion of informal self-employment is consistent with the traditional segmentation views of informality. However, we also identify episodes where informal self-employment behaves “pro-cyclically”; here, informality is driven by relative demand or productivity shocks to the non tradable sector.     

THE POLITICAL ECONOMY OF PUBLIC‐PRIVATE PARTNERSHIPS AND ANALYSIS OF THEIR SOCIAL VALUE*

ABSTRACT: This article applies political economy theory to public‐private partnerships (PPPs). First, we propose that social welfare is the appropriate normative evaluation criterion to evaluate the social value of PPPs. Second, we specify the goals of PPP participants, including private‐sector partners and governments. Third, we review the observed outcomes of PPPs and analyze them from both a political economy perspective and a social welfare perspective. Fourth, based on a comparison of the actual outcomes of PPPs to normatively desirable social welfare outcomes, we propose some ‘rules for governments’ concerning the design of government PPP institutions and the management of PPPs. We argue that if governments were to adopt these rules there would be fewer PPPs in total, they would be more like traditional government contracts and there would be a greater likelihood of improved social welfare. However, political economy theory also explains why implementation of any reform will be difficult.     

EFFICIENCY AND LABOR MARKET DYNAMICS IN A MODEL OF LABOR SELECTION

This article characterizes efficient labor market allocations in a labor selection model. The model's crucial aspect is cross‐sectional heterogeneity for new job contacts, which leads to an endogenous selection threshold for new hires. With cross‐sectional dispersion calibrated to microeconomic data, 40% of empirically relevant fluctuations in the job‐finding rate arise, which contrasts with results in an efficient search and matching economy. The efficient selection model's results hold in partial and general equilibrium, as well as with sequential search.     

Labor market structure and offshoring

We consider a two‐country, two‐sector model in which a firm’s offshoring decision depends on labor market rigidities that impose additional costs on the firm. Firms endogenously choose their organizational form considering their productivity level and organizational costs. The costs generated by labor market frictions play a key role in determining the benefits of each organizational structure, and thus helps determine the conditions under which a firm decides to offshore. There are three different types of equilibria depending on the relative levels of the domestic and foreign labor market costs and the price of the intermediate input. In all equilibria, a relative rise in the domestic labor market cost increases the share of firms that offshore, while decreasing domestic integration. Furthermore, an economy with offshoring has a higher welfare level and a lower unemployment rate than it would under autarky.     

COMPETING EXPLANATIONS OF U.S. DEFENSE INDUSTRY CONSOLIDATION IN THE 1990s AND THEIR POLICY IMPLICATIONS

Was the consolidation of defense industry in the 1990s driven by U.S. Department of Defense (DOD) directives, or was it driven instead by the same forces that drove consolidation in many other sectors of the U.S. economy in the 1990s? To better understand the roles of DOD policy and economy‐wide forces in shaping the U.S. defense industry, we test for structural breaks in defense industry and spending data and compare our findings to those relating to other sectors and the general economy. We identify structural breaks in the defense‐related data in the early 1980s and throughout the 1990s, roughly consistent with changes in the U.S. economy, including broader merger trends. Overall, our results are more consistent with the view that economy‐wide factors drove defense industry consolidation, largely independent of the DOD policy changes that occurred early in the 1990s.

On the Growth and Welfare Effects of Defense R&D

In the United States, defense R&D share of GDP has decreased significantly since 1960. To analyze the implications on growth and welfare, we develop an R&D‐based growth model that features the commonly discussed crowding‐out and spillover effects of defense R&D on civilian R&D. The model also captures the effects of defense technology on (a) national security resembling consumption‐type public goods and (b) aggregate productivity via the spin‐off effect resembling productive public goods. In this framework, economic growth is driven by market‐based civilian R&D as in standard R&D‐based growth models and government‐financed public goods (i.e., defense R&D) as in Barro (1990). We find that defense R&D has an inverted‐U effect on growth, and the growth‐maximizing level of defense R&D is increasing in the spillover and spin‐off effects. As for the welfare‐maximizing level of defense R&D, it is increasing in the security‐enhancing effect of defense technology, and there exists a critical degree of this security‐enhancing effect below (above) which the welfare‐maximizing level is below (above) the growth‐maximizing level.     

Foreign Direct Investment and Domestic Child Labor

Empirical evidence suggests that use of child labor as domestic help has increased significantly in recent years although the overall incidence of child labor across the globe has declined satisfactorily. This should draw the attention of economists and policymakers because domestic child labor is considered as exploitative and in many cases hazardous. This paper purports to explain this apparently perplexing finding theoretically in terms of a three‐sector general equilibrium model with a nontraded sector where only child labor is used to render services to the richer section of the society. The analysis shows how FDI‐led economic growth increases the size of the services sector although it lowers the overall incidence of child labor in the economy and improves the welfare of the poor families that supply child labor. Finally, a composite policy has been recommended that can deal with all three aspects favorably.     

THE POVERTY REDUCTION SUCCESS OF PUBLIC TRANSFERS FOR WORKING AGE IMMIGRANTS AND REFUGEES IN THE UNITED STATES

Although there has been some research on the impacts of federal tax and transfer policies on poverty rates for immigrants, virtually no previous work investigates the most disadvantaged group of immigrants: refugees. We estimate probit models for three standard measures of poverty. We find that while immigrants and refugees in particular had much higher poverty rates in the early 1990s, the strong economic growth of the 1990s led to a convergence of those poverty rates by 2000. Our analysis demonstrates that the improvement was largely because of economic conditions and that welfare reform policies appear to have little differential impact on immigrants or refugees. We also find that refugees show a markedly greater response to local labor market conditions than other immigrants or native born. (JEL H3, I3, J1)
