TRADE LIBERALIZATION AND WAGE PREMIUM IN ARGENTINA: THE ROLE OF TRADE FACTOR INTENSITY

During the 1990s, several Latin American countries implemented policies directed to the removal of barriers on international trade. However, there is a perception that reforms, especially trade liberalization, failed to deliver on their promises, easing the way for policies aimed at reversing some of them. Following Wood's hypothesis, we allow for the effects of liberalization to vary, depending on the skill intensity of production. The evidence confirms that the role of trade liberalization has been relatively small, but controlling for the presence of endogeneity gives larger estimates. Contrary to previous evidence, the wage premium of skilled workers was more sensitive to the increase of skill‐intensive exports than to that of unskilled‐intensive imports.     

PRICE‐SETTING BEHAVIOR IN TURKISH INDUSTRIES: EVIDENCE FROM SURVEY DATA

This study investigates the price‐setting behavior of Turkish industries based on the results of a survey that was conducted by the Central Bank of the Republic of Turkey. The results show that, under normal conditions, the majority of the firms follow a time‐dependent pricing rule but when significant events occur a substantial fraction of them alter their behavior to state‐dependent reviewing. The median Turkish firm reviews its prices every month, but changes its prices four times a year. Price reviews and changes are affected by: the market share, price discrimination, customer type, firm size, and the existence of regulated prices.     

DETERMINANTS OF SOUTH AFRICA‐US INTRA‐INDUSTRY TRADE IN SERVICES: A WILD BOOTSTRAP DYNAMIC PANEL DATA ANALYSIS1

The study attempts to empirically identify factors that determine South Africa–US intra‐industry trade (IIT) in selected services during the period 1994‐2002. The study utilises Liu‐Davidson‐Flachaire wild bootstrap, which is robust to heteroscedasticity and provides estimates of the degree of parameter bias. The empirical results, in principle, show that South Africa–US IIT in the selected services is determined by factors similar to goods‐based “North‐South” IIT studies. Specifically, differences in per capita income and differences in market size negatively affect IIT. The study also indicates that US foreign direct investment in South Africa positively contributes to the unaffiliated IIT in services.     

Relating Product Prices to Long‐Run Marginal Cost: Evidence from Solar Photovoltaic Modules

A basic tenet of microeconomics is that for a competitive industry in equilibrium the market price of a product will be equal to its marginal cost. This paper develops a model framework and a corresponding empirical inference procedure for estimating long‐run marginal cost in industries where production costs decline over time. In the context of the solar photovoltaic (PV) module industry, we rely primarily on firm‐level financial accounting data to estimate the long‐run marginal cost of PV modules for the years 2008–2013. During those years, the industry experienced both unprecedented price declines and significant expansions of manufacturing capacity. We compare the trajectory of average sales prices with the estimated long‐run marginal costs in order to quantify the extent to which actual price declines were attributable to reductions in production costs. The trajectory of estimated product costs is then extrapolated to forecast an equilibrium trend line for future PV module prices.     

PRICE ELASTICITIES AND PRICING POWER IN EMERGING MARKETS: THE CASE OF PETROCHEMICAL‐DERIVED PLASTICS IN SOUTH AFRICA1

This paper examines whether there necessarily exists a conflict between allocative and productive efficiency in small open economy markets. That productive efficiency favours market concentration is not in dispute, and the sole question we face is whether allocative efficiency suffers under high market concentration. We proceed theoretically and econometrically. We find that the conflict between productive and allocative efficiency is not necessarily as stringent as the international competition policy literature suggests should be the case. In particular, we note that the strategic interaction between the large domestic producer and its competitors makes feasible a range of alternative price elasticities of demand, and empirically that all price elasticities of demand are less than or equal to unity. Nevertheless, the impact of market structure is such as to render feasible a wide range of possible levels of pricing power.     

SHORT‐RUN AND LONG‐RUN DETERMINANTS OF THE REAL EXCHANGE RATE IN MEXICO

This paper explores the real exchange rate behavior in Mexico from 1960 until 2005. Since the empirical analysis reveals that the real exchange rate is not mean reverting, we propose that economic fundamental variables affect its evolution in the long run. Therefore, based on equilibrium exchange rate paradigms, we propose a simple model of real exchange rate determination, which includes the relative GDP per capita, the real interest rates, and the net foreign assets over a long period of time. Our analysis also considers the dynamic adjustment in response to shocks through impulse response functions derived from the multivariate vector autoregressive (VAR) model.     

THE LEGACY AND CHALLENGE OF FISCAL POLICY IN SUB‐SAHARAN AFRICA1

This paper traces salient aspects of the evolution of fiscal policy in sub‐Saharan Africa since 1960 and highlights the need for further reforms to consolidate the gains of the recent past. The fiscal position of the sub‐Saharan African region as a whole has improved markedly during the past ten years, but most countries still face formidable fiscal challenges. To consolidate the progress made during the past decade and to tackle the remaining problems, sub‐Saharan African policymakers should remain firmly committed to sound fiscal policies.     

MIGRATION AND ECONOMIC GROWTH IN BRAZIL: EMPIRICAL APPLICATIONS BASED ON THE SOLOW‐SWAN MODEL

The paper addresses the question of whether migration plays a role in the determination of the per capita incomes in sub‐regions of Brazil. In order to discuss this relationship, we slightly modified the Solow‐Swan model with migration to better resemble the Brazilian context. Based on this model, we determined theoretically five different possibilities for the spatial dynamics regarding net migration, human capital differentials between migrants and nonmigrants, and capital stock per effective worker. We applied this framework to census data and the microregions in Brazil were empirically classified in one or other of these possibilities with the multivariate technique of cluster analysis. Finally, we used econometric models with instrumental variables applied to panel data and observed a tendency of increase in the variability of per capita income due to migration.
