FDI Liberalization as a Source of Comparative Advantage in China

Two features of China's trade patterns suggest that elements beyond factor abundance explain its export performance. The high penetration in world markets of labor-intensive products has been accompanied by: (i) a high share in exports of productivity-advanced foreign-invested enterprises (FIEs) and (ii) a high penetration of FIEs in labor-intensive sectors. We show that FDI liberalization endogenously introduces Ricardian features to an otherwise standard endowment-based trade model, strengthening China's natural comparative advantage in labor-intensive products. We discuss how capital accumulation, productivity growth, rural–urban migration, incentives for foreign investment, and distortions in financial markets affect this bias.     

Does Latin America Have More to Gain From Exchange Rate Liberalization than Sub-Saharan Africa?

An examination of the relationship between exchange rate liberalization and economic growth in selected Latin American and Sub-Saharan African countries reveals evidence of a short-run causal relationship between the two variables in both Latin America and Sub-Saharan Africa. Within each region, exchange rate liberalization causes growth in some countries while others exhibit reverse causality running from growth to exchange rate leads to increased growth and growth induces exchange rate liberalization in most Latin American countries, in the majority of Sub-Saharan African countries studied, exchange rate liberalization reduces growth while growth causes distortions in the exchange rate. Market imperfections, expansionary fiscal and monetary policies under a fixed exchange rate regime, and poor terms of trade are cited as possible explanations for the findings for Sub-Saharan Africa.

Political democratization, economic liberalization, and growth volatility

This study empirically investigates the effects of political and economic liberalization on growth volatility using a difference-in-difference method for a sample of 158 countries over the 1970-2005 period. The results show that, when examined separately, economic liberalization leads to a significant reduction in volatility while democratization is not followed by a decrease in growth volatility. For countries that undertake only one liberalization, opening up the economy to international trade reduces volatility in growth; becoming a democracy, on the other hand, seems to increase macroeconomic instability. For countries that implement both political and economic liberalizations, no statistically significant effect on volatility is detected. These results serve to provide additional support for the policy recommendation that developing countries should liberalize their economy first and then consider political liberalization.     

Measuring market distortion: international comparisons,policy and competitiveness

This paper develops a framework to simultaneously estimate production possibility frontiers and measure distortions in factor and product markets. The econometric results, based on a panel of 61 countries over the period 1970 through 1985, reveal very little distortion in factor markets but considerable distortion in product markets. In addition, the distortions tend to vary with the cyclical behaviour of economic activity. Further, the results suggest that in order to improve efficiency, commercial policy should aim at reducing product-market distortions rather than factor-market ones.     

Quantifying the impact of services liberalization in a developing country

We compare goods versus services liberalization in terms of welfare, outputs, and factor prices in Tunisia using a CGE model with multiple products, services and trading partners. Restraints on services trade involve both cross-border supply (tariff-equivalent price wedges) and on foreign ownership (monopoly-rent distortions and inefficiency costs). Goods-trade liberalization yields a modest gain in aggregate welfare. Reducing service barriers generate relatively large welfare gains and low adjustment costs. Services liberalization increases economic activity in all sectors and raise the real returns to both capital and labor. The results point to the potential importance of deregulating services provision for economic development.     

Aggregate productivity and aggregate technology

Aggregate productivity and aggregate technology are meaningful but distinct concepts. We show that a slightly modified Solow productivity residual measures changes in economic welfare, even when productivity and technology differ because of distortions such as imperfect competition. Our results imply that aggregate data can be used to measure changes in welfare, even when disaggregated data are needed to measure technical change. We then present a general accounting framework that identifies several new non-technological gaps between productivity and technology, gaps reflecting imperfections and frictions in output and factor markets. Empirically, we find that these gaps are important, even though we abstract from variations in factor utilization and estimate only small average sectoral markups. The evidence suggests that the usual focus on one-sector DSGE models misses a rich class of important propagation mechanisms that are present only in multi-sector models.     

The Sovereign Yield Curve and the Macroeconomy in China

A dynamic Nelson–Siegel model is adopted to estimate three time‐varying factors of yield curves, the level, the slope and the curvature, and a vector autoregressive model is built to study interactions between macro variables and the yield curve. Results show that, first, money supply growth is a more effective instrument to curb inflation than the monetary policy interest rate; however, the central bank also adjusts the interest rate to stabilize money supply. Second, investment is an important measure to stimulate the Chinese economy, but it also pushes up money supply growth, which results in higher inflation. Third, the yield curve reacts significantly to innovations to investment growth and money supply growth. The segmentation of China's bond market hinders the efficient implementation of monetary policy, and the monetary policy transmission mechanism is still weak in China. Finally, interactions between the yield curve and the macroeconomy in China are nearly unidirectional. Macroeconomic variables reshape the yield curve, but direct adjustments of the yield curve do not significantly change macroeconomic variables. Due to the incomplete liberalization of financial markets, there exists a wide disjunction between the real economy and financial markets in China.     

Nominal Wage Flexibility and Economic Performance: Evidence and Implications Across Industrial Countries

By considering the theoretical connection between labour and product markets, the paper evaluates the economic relationship of these markets within the contractual wage rigidity New Keynesian explanation of business cycles. The empirical analysis focuses on the short‐run cyclical behaviour of real output, prices and wages for 19 industrial countries. Time‐series and cross‐sectional regressions are estimated. Cross‐sectional cyclical correlations in the labour and goods markets are also evaluated across countries. Consistent with the theoretical predictions, aggregate uncertainty is an important factor in increasing the flexibility of the nominal wage in response to aggregate demand shocks. Wage flexibility accelerates price inflation and moderates the response of real output growth to aggregate demand shocks. Wage flexibility does not appear to be an important factor in differentiating the real and inflationary effects of energy price shocks across countries. Finally, aggregate uncertainty increases the responsiveness of output and price to productivity shocks.     

Optimal Factor Taxation under Wage Bargaining: A Dynamic Perspective

Abstract. We consider the issue of steady-state optimal factor taxation in a Ramsey-type dynamic general equilibrium setting with two distinct distortions: (i) taxes on capital and labour are the only available tax instruments for raising revenues and (ii) labour markets are subject to an inefficiency resulting from wage bargaining. If considered in isolation, the two distortions create conflicting demands on the wage tax, while calling for a zero capital tax. By combining the two distortions, we arrive at the conclusion that both instruments should be used, implying that the zero capital tax result in general is no longer valid under imperfectly competitive labour markets.     

Effects of financial liberalization on financial market development and economic performance of the SSA region: An empirical assessment

This study investigates the role of financial liberalization in promoting financial deepening and economic growth in Sub-Saharan African countries (SSA). We apply the more efficient system GMM estimator in dynamic panel data that combines first difference and original level specification to deal with the problems of weak instruments. Our dataset covers 21 countries in Sub-Saharan Africa over the period of 1981–2009.Additionally, the paper sought to examine both the direct and indirect impacts of financial liberalization policies on economic growth and financial deepening using a much more comprehensive and recent financial liberalization dataset. The econometric results suggest that, on average, financial liberalization is negatively associated with income growth in SSA region. Our findings provide support for the skeptical empirical view of financial liberalization in emerging markets, which show that liberalization, by itself, might be associated with lower economic growth through leading to destabilization, stimulating domestic capital flight and increasing the risk of financial fragility. However, the research finds that financial liberalization does indeed impact positively on financial deepening and resource mobilization in SSA region, after controlling for key macroeconomic factors such as institutional quality, fiscal imbalances and inflation. In fact the study reports a stronger reforms effect for countries that have stronger legal institutions, protection of property rights and higher human capital. Policy-wise, the study finds that institutional and human capital factors are important in explaining growth and financial development; therefore, it is necessary for SSA governments to promote a stronger and more transparent institutional development as we move forward.     

Labor market distortions and China's WTO accession package:: an applied general equilibrium assessment

The economic implications of China's accession to the World Trade Organization have been analyzed using applied general equilibrium techniques. We explore the consequences of trade reform in the presence of labor market distortions. A formal model of imperfect labor mobility is incorporated into a large-scale, stochastic applied general equilibrium framework with which the consequences of China's trade reform for net welfare are considered. The simulations suggest that distortions in China's labor market, including imperfect labor mobility, rural-urban migration, dual urban markets and surplus rural labor, have significant effects on trade liberalization outcomes and in some cases produce unexpected second-best results.

Labour market institutions and labour market performance

This paper studies the relationship between labour market institutions and policies and labour market performance using a new and unique dataset that covers the countries of Eastern Europe and Central Asia, which in the last two decades experienced radical economic and institutional transformations. We document a clear trend towards liberalization of labour markets, especially in the countries of the former Soviet Union, but also substantial differences across the countries studied. Our econometric analysis implies that institutions matter for labour market outcomes, and that deregulation of labour markets improves their performance. The analysis also suggests several significant interactions between different institutions, which are in line with the idea of beneficial effects of reform complementarity and broad reform packages.     

Productivity in a Distorted Market: The Case of Brazil's Retail Sector

In a model of monopolistic competition with heterogeneous firms, distortions in prices drive a wedge between the marginal revenue products of factor inputs across firms. We use census data for Brazil's retail sector to study implications for aggregate productivity and relate distortions to regional variation in regulation using a differences‐in‐differences approach. Taxes, entry regulation, and access to credit may create distortions to output and capital that varies by firm size. Potential gains from reallocation have not diminished despite the process of services liberalization in the 1990s.     

Australia and the Pacific Economy*

The industrialization and growth of East Asian countries has shifted the centre of world trade and economic activity towards the Pacific. There has already been a huge redirection of Australia's trade and external economic interests towards the region, based importantly on the emergence of Japan as a major economic power. Australia's future economic prospects will be significantly determined by how it manages its trade policy interests in the context of continuing East Asian industrialization. The most promising Australian trade policy approach is one which allies Australia's trading interests to those of East Asian countries in seeking to maintain an open non-discriminatory trade regime, supportive of the transformation of trade specialization necessary to the industrialization of resource-deficient countries, and which marries that objective to the liberalization of her own and Pacific country markets.     

On the growth and welfare effects of monopolistic distortions

The most fundamental proposition about growth and competition is that there is a tradeoff between static welfare and long-term growth. This paper reconsiders this basic proposition in an expanding variety endogenous growth model with competitive markets for “old” innovative products and for a traditional good. We shed light on some implications of monopolistic distortions which tend to be ignored by standard models. First, no growth may be better than some growth, since modest positive growth potentially requires sizeable static welfare losses. Second, the economy may converge to a steady state with zero growth, even though a locally saddle-point stable steady state with positive growth exists if the initial share of “cheap” competitive markets is sufficiently high, as this implies a relatively low demand for “expensive” innovative goods. Third, such a “no-growth trap” may happen in a world economy made up of several countries engaged in free trade with each other. The policy implications are that growth-enhancing policies may be misguided and that quick deregulation as well as quick trade liberalization can lead to stagnation in the long term.

Monetary business cycle accounting

This paper investigates the quantitative importance of various types of distortions for inflation and nominal interest rate dynamics by extending business cycle accounting to monetary models. Representing various classes of real and nominal distortions as ‘wedges’ in standard equilibrium conditions allows a quantitative assessment of those distortions. Decomposing the data into movements due to these wedges shows that distortions generating movements in TFP and wedges in equilibrium conditions for asset markets are essential. In contrast, wedges capturing the effects of sticky prices play less important role. These results are robust to alternative implementations of the accounting method.     

Endogenous Growth and Trade Liberalization Between Small and Large Countries

The paper combines insight from new trade theory and R&D-based endogenous growth models to argue that there are ambiguous growth effects of trade liberalization between countries that differ in terms of the size of their home markets. In particular, trade liberalization may reduce R&D incentives in countries with low purchasing power without invoking parallel increases in countries with high purchasing power. The paper also considers the case of imperfect international knowledge spillovers, and demonstrates that complete trade liberalization may affect the growth rate negatively.
