Financial liberalization, structural change, and real exchange rate appreciations

The last twenty years have witnessed periods of sustained appreciations of the real exchange rate in emerging economies. The case of Mexico between 1988 and 2002 is representative of several episodes in Latin America and Central and Eastern Europe in which countries opening to capital flows experienced large appreciations accompanied by a significant reallocation of workers towards the non-tradable sector. We account for these facts using a two sector dynamic general equilibrium model of a small open economy with frictions to labor reallocation and two driving forces: (i) A decline in the cost of borrowing in foreign markets, and (ii) differential productivity growth across sectors. These two mechanisms account together for 60% of the decline in the domestic relative price of tradables in Mexico and for a large fraction of the observed reallocation of labor across sectors. The decline in the interest rate faced by Mexico in international markets is quantitatively the most important channel. Our results are robust to the inclusion of terms of trade into the model.     

EXTERNAL SHOCKS AND THE URBAN POOR

This paper examines the effect of external shocks on urban poverty in a two‐household (rich and poor), two‐sector intertemporal model of an open economy with segmented labor markets. Skilled and unskilled labor are used in the formal sector, whereas only unskilled labor (which moves freely across sectors) is used in the informal economy. The extent to which a permanent increase in the world risk‐free interest rate affects the incidence and depth of poverty is shown to depend crucially on the wedge between consumption and product wages. The model is also extended to account for endogenous minimum wages and capital accumulation.     

Exchange rate fluctuations and quality composition of exports: Evidence from Swiss product-level data

This paper studies the relationship between exchange rate movements and the average export quality using disaggregated Swiss product-level data between 1996 and 2015. We find evidence at different levels of aggregation that the average export quality increases in response to a currency appreciation through compositional effects: currency appreciations shift market shares towards goods that are more expensive and of higher quality. This exchange rate effect on quality is more pronounced for differentiated goods and in sectors with a greater scope for quality differentiation. From a policy perspective, this reallocation effect points to the importance of facilitating structural changes in the export composition to increase the resilience of the export sector to exchange rate shocks. Our results also suggest a positive relationship between the average export quality and aggregate export sales. From a methodological point of view, the findings imply that exchange rate pass-through estimations without quality controls tend to be biased regardless of aggregation level or type of data.     

Job creation, job destruction, and the real exchange rate

Welfare gains from trade are reduced by adjustment costs associated with factor reallocation, but most studies of the effects of trade on labor markets focus only on net employment change. This paper takes a step toward identifying trade-related adjustment costs by estimating the effects of real exchange rates on labor reallocation using a new model of gross job creation and destruction applied to detailed U.S. manufacturing industries between 1973 and 1993. Trend real exchange rates significantly affect job reallocation but not net employment. Cyclical real exchange rates significantly affect net employment through job destruction only.     

Agricultural productivity differences and credit market imperfections

This paper presents a simple model to examine the implication of credit market imperfections when considering the huge variation of agricultural labor productivity across countries. The development of credit markets enables more agents to acquire skills to work in non-agricultural sectors. The expansion of the sectors decreases the labor supply to agriculture as well as increases the supply of modern intermediate inputs to agriculture. Agricultural producers accordingly substitute the relatively cheap intermediate inputs for labor to produce a given level of an agricultural good, and, thereby, the output per worker in agriculture is improved. Poor countries with less developed credit markets are, therefore, far less productive in agriculture than rich countries with well-developed credit markets.     

The role of FDI in structural change: Evidence from Mexico

Foreign direct investment (FDI) flows to Mexico are substantial and play an important role in the Mexican economy since the mid-1990s. These investments reflect the activities of multinational firms that shape to some extent the economic landscape and sectoral structure in this host country. We illustrate that there is considerable variation in the amounts of FDI and structural change within the country and across time. Based on this, the paper's main purpose is to analyse whether there is a significant impact of FDI on structural change. We conduct an empirical analysis covering the period 2006–16. We use the fixed-effects estimator where the unit of observation is a Mexican state for which we calculate structural change from the reallocation of labour between sectors. The results suggest that (if any) there is a positive effect from FDI on growth-enhancing structural change. This effect depends critically on the lag structure of FDI. Moreover, there is some evidence that the positive effect (a) arises from FDI flows in the industry sector and (b) is present for medium and low-skilled labour reallocation.     

Sovereign debt crises and credit to the private sector

We use micro-level data to analyze emerging markets' private sector access to international debt markets during sovereign debt crises. We find that these crises are systematically accompanied by a decline in foreign credit to domestic private firms, both during debt renegotiations and for over two years after restructuring agreements are reached. This decline is large, statistically significant, and robust. We find that this effect is concentrated in the non-financial sector and is different for firms in the exporting and in the non-exporting sectors. We also find that the magnitude of the effect depends on the type of debt restructuring agreement.     

Mexican peso crisis and its spillover effects to emerging market debt

This paper examines the spillover effects of the Mexican financial crisis to emerging financial markets. As of November 1994, the financial markets were not anticipating a change in exchange rate regime in Mexico. Coincident with the peso devaluation on 20, December 1994, Mexican Brady bond prices declined significantly and continued to experience significant decline during the subsequent three months. Emerging market assets reacted differently to the Mexican crisis. Latin America as a region was more exposed to the Mexican crisis than emerging markets from other regions. The ratio of liquid monetary assets to international reserves and the ratio of current account to GDP were the most influential variables in explaining variation in CARs across countries. Trade competition with third markets was the most significant transmission channel during the Mexican crisis.     

Trade reform,infrastructure investment,and structural transformation in Africa: Evidence from Guinea-Bissau

This study examines the impacts of trade reform and infrastructure investment on structural transformation and poverty alleviation in Guinea-Bissau using a dynamic computable general equilibrium model. We found that partial or complete tariff rate cuts accompanied by a scaling-up infrastructure investment funded by debt only positively impact macro-and micro-outcomes but do not generate structural transformation. Conversely, trade reform and infrastructure investment funded by a mix of debt and tax rates on the firm's income generate structural transformation with labor reallocation from agriculture to non-agricultural sectors. This structural transformation pattern favors the poor and contributes to reducing income inequality over time.     

Mexico's integration into the North American capital market

We explore a model of time varying regional market integration that includes three factors for the North American equity market, the local Mexican equity market and the peso/dollar exchange rate. We argue that a useful instrument for the degree of integration is the sovereign yield spread. Applying our methodology to Mexico over the 1991–2002 period, we show that the degree of market integration was higher at the end of the period than at the beginning but that it exhibited wide swings that were related to both global as well as local events. We also discover that Mexico's currency risk is priced. Further, the currency returns process reveals strongly significant asymmetric volatility that is strongly related to the asymmetric volatility of the Mexican equity market returns process. A plausible reason for these results is that currency devaluations in emerging markets like Mexico can cause default-risk crises in local banking systems that mismatch local-currency assets and hard currency liabilities, whereas appreciations produce no such problems. Devaluations that destabilize banking systems are, therefore, more likely than appreciations to increase the volatilities of both the currency's and the equity market's returns.     

Factor allocation,economic growth and unbalanced regional development in China

On the basis of development accounting techniques and a factor misallocation framework, we use panel data of 30 Chinese provinces from 2000 to 2013 to assess how factor allocation affects economic growth and unbalanced regional development in China. In particular, we decompose economic growth into three parts, namely sector productivity (SP ), factor market efficiency (FME ) and factor endowment (FE ). We then conduct counterfactual analyses to investigate the short and long‐run roles of factor allocation in the income distribution across provinces. The results show that SP , FME and FE can explain 23%, 8.5% and 68.5% of economic growth, while labour, capital and energy reallocation account for aggregate productivity growth of about 47%, −4.8% and −0.1%. Furthermore, when the factors are efficiently allocated, transferring labour (capital, energy) from agriculture (service, industry) to the other sectors will increase the income per capita by 29.5% and 42.5% in the short and long term. Meanwhile, efficient factor allocation accounts for 32% and 29.7% of aggregate productivity and reduces the income variation across provinces by 25.5% and 23% in the short and long run, respectively.     

Labor market institutions,firm-specific skills,and trade patterns

This paper studies how a country's labor market institutions, by affecting workers' skill acquisition, can shape its export patterns. I develop an open-economy model in which workers undertake non-contractible activities to acquire firm-specific skills on the job. In the model, labor market protection raises workers' incentives to acquire firm-specific skills relative to general skills, turning labor laws into a source of comparative advantage. In particular, the model shows that countries with more protective labor laws export relatively more in firm-specific skill-intensive sectors at both the intensive and extensive margins. To test the theoretical predictions, I construct sector proxies for the firm-specific and industry-specific skill intensity by estimating returns to firm tenure and industry tenure for different U.S. manufacturing sectors during the 1974–1993 period. By estimating sector-level gravity equations for 84 countries using the Helpman–Melitz–Rubinstein (2008) framework, I find evidence supporting the predicted effects of labor market institutions at both margins of exports.     

Productivity Dispersion and its Determinants: The Role of Import Penetration

The new heterogeneous firm models in international economics predict a negative impact of trade openness on within-sector productivity disparities, due to a restructuring process leading to a reallocation of resources towards more efficient firms and the exit of less productive ones. I test this hypothesis for the Italian manufacturing sectors making use of panel data models. I investigate the existence of heterogeneous effects in terms of origin of imports and I account for a geographical dimension computing the productivity dispersion indicator by sector and regional macro-area. The analysis is implemented within a comprehensive framework controlling for other potential determinants, such as technological factors and domestic competition. My findings show that competitive pressure from low income countries reduces the productivity heterogeneity across firms. On the contrary, a positive impact is detected for the increased availability of intermediates originating from developed countries.     

中国现代部门劳动分配比例的变动趋势与影响因素——基于中国省级面板数据的分析

中国劳动分配比例的下降是由现代部门劳动分配比例的下降引起的。对中国1996—2004年省级面板数据的估计结果表明,中国现代部门劳动分配比例下降的根本原因是二元经济条件下的巨大就业压力、不断提高的劳均资本和人力资本、工会在保护劳动者权益方面的缺位。该结果对不同的模型设置和样本选择具有很强的稳健性。进一步的研究还发现,在低发展水平组,劳均资本对劳动分配比例的负面影响更大。     

Establishment Size and Local Employment Growth

In a sample of more than 2000 U.S. counties, smaller average establishment size is generally associated with faster subsequent growth rates of sectoral employment, both within and across sectors. The estimated effects are large in magnitude and thus economically important, and are consistent with several theories previously developed. These findings contribute toward a more precise understanding of the role of small businesses in economic growth and labor markets.     

Immigration and structural change: Evidence from post-war Germany

Does immigration accelerate sectoral change from low- to high-productivity sectors? This paper analyzes the effect of one of the largest population movements in history, the influx of millions of German expellees to West Germany after World War II, on Germany's speed of transition away from low-productivity agriculture. A simple two-sector specific factor model, in which moving costs prevent the marginal product of labor to be equalized across sectors, predicts that expellee inflows boost output per worker by expanding the high-productivity non-agricultural sector but decrease output per worker within sectors. Using German district-level data from before and after the war, we find empirical support for these predictions.     

Trade shocks,product mix adjustment and productivity growth in Italian manufacturing

In this paper, we use firm-level data on the universe of Italian manufacturing multi-product exporters to test whether demand shocks in export markets lead multi-product exporters to increase their productivity. The main mechanism behind the documented productivity gains is the reallocation of resources across products within firms (American Economic Review, 104, 2014 and 495; National Bureau of Economic Research Working Paper Series No. 22433, 2016). Intuitively, the increased demand stemming from foreign markets will induce firms to adjust their product mix by moving inputs from low to high productive/profitable uses. We find that these productivity gains are significant and can explain between 1/10 and 1/2 of aggregate productivity growth in the manufacturing sector.     

The exchange rate susceptibility of European core industries, 1995–2010

This study investigates reactions to real exchange rate changes in the German, French and UK automobile and mechanical engineering sectors using monthly data from 1995 to 2010. Our findings indicate that EUR /US$ appreciations hamper exports, but do not necessarily imply an aggravated business climate or export order‐book assessment. This does not apply to the GBP /US$ and corresponding time series for the UK . First and foremost, our fixed coefficient and time‐varying parameter VAR model estimates confirm the extraordinary role of the German key sectors, while currency union membership seems to play a minor role at best. Overall, the exchange rate susceptibility is less profound than claimed by lobbies and held as popular belief.     

国际贸易、技术变动对我国工业部门劳动收入份额的影响

文章较为系统地分析了国际贸易、技术进步等因素对中国工业部门劳动收入份额的影响。研究显示在1999～2009年期间,我国工业部门的劳动收入份额总体上呈现出缓慢下降的趋势,工业部门劳动收入份额变动主要是行业内部劳动力再配置的结果;利用中国工业部门21个细分行业的面板数据,通过系统广义矩方法对国际贸易、技术变革对行业劳动收入份额的影响进行计量分析表明,国际贸易具有较为显著的提高我国工业部门行业劳动份额的效应,而技术进步则存在显著降低工业行业劳动份额的效应,这与我国工业部门在研究期内的技术进步具有劳动节约型特征有关。     

Regime switching in the reactions of stock markets in Saudi Arabia to oil price variations

The study revisits the stock–oil nexus by examining the reactions of equity markets to oil price shocks at national and sectoral levels for Saudi Arabia in a time‐varying framework by employing the Markov switching EGARCH model developed by Henry (2009, Journal of Banking and Finance, 33, 405). Based on weekly data, the findings reveal that the behaviour of all stock markets switches between an expansion regime and a recession regime, with more persistence for the expansion state. Additionally, influential international events associated with stock market drops are clearly identified in the recession regime. Furthermore, there is evidence of asymmetric reactions of the equity index returns and the probabilities of transition from one state to another to oil price variations, with heterogeneous impacts across sectors and regimes. The stock markets are more sensitive to oil price decreases than to oil price increases. Although the evidence of relatively slight differences in some findings across weekdays, the study allows investors and policymakers to understand well the interactions of stock sector markets vis‐à‐vis the world oil market in a regime‐switching framework, in order to make the right decision as regards portfolio diversification and regulation of the stock markets.
