Impact of trade liberalisation on labour market and poverty in Sri Lanka. An integrated macro-micro modelling approach

This paper revisits the long standing controversy of trade and poverty linkage using a macro-micro modelling approach based on general equilibrium and microsimulation analytical frameworks. Sri Lanka, the first country in South Asia which undertook trade reforms more than three decades ago, is taken as a case in point in this study. The paper analyses the effects of trade liberalisation on income distribution and poverty in the urban, rural and estate sectors in Sri Lanka using the first ever microsimulation model built for the country in combination with a multi-household computable general equilibrium (CGE) model. The results reveal that without any fiscal policy adjustments a 100% tariff cut would lead to an increase in economic growth and a reduction in poverty incidence both in the short run as well as in the long run. However, when the tariff cut combined with the fiscal policy adjustments to maintain the budget neutrality, poverty outcomes showed mixed results. In contrast, results show that trade liberalisation increases the income inequality in Sri Lanka.     

Structural reforms and growth in transition

The present fiscal difficulties of many countries amplify the call for structural reforms. To provide stylized facts on how reforms worked in the past, we quantitatively review 60 studies estimating the relationship between reforms and growth. These studies examine structural reforms carried out in 26 transition countries around the world. Our results show that an average reform caused substantial costs in the short run, but had strong positive effects on long‐run growth. Reforms focused on external liberalization proved to be more beneficial than others in both the short and long run. The findings hold even after correction for publication bias and misspecifications present in some primary studies.     

Crisis and Recovery: What We Have Learned from the South Korean Experience?*

This paper analyzes the process of recovery from the 1997 financial crisis in South Korea, and draws some lessons from it. The fast restoration of financial stability due to early closure of non‐viable financial institutions and quick resolution of non‐performing loans was critical for the speedy recovery of the South Korean economy. The swift adjustment in fiscal and monetary policies in addition to the large depreciation of real exchange rates also supported the fast recovery. Corporate and government bond markets played an important role in the financial restructuring and macroeconomic adjustment process. Structural reforms helped to alleviate the weaknesses in the corporate sector, particularly in chaebol groups. However, the fast recovery also generated unwelcome side‐effects. Because of aggressive fiscal expansion through government‐guaranteed bonds and public credit guarantee programs, sovereign liabilities increased greatly and transparency of the official fiscal stance deteriorated. Thanks to structural reform, corporate and financial sectors began to recognize the importance of micro risk management, but increased risk aversion contributed to the slowdown of corporate investment and, therefore, reduced long‐run growth perspective in South Korea. How to revive long‐term growth rates remains an important question in South Korea despite fast recovery from the crisis.     

A SURVEY ON THE OUTPUT EFFECTS OF TAX REFORMS FROM A POLICY PERSPECTIVE

This study reviews the existing evidence on the effects of tax reforms on output levels and growth over the short and long run from different strands of the literature. It develops and applies criteria to evaluate the usefulness of ex‐post estimates to predict the effects of tax reforms ex ante. Based on these criteria, we present detailed tables summarizing and comparing ex‐post estimates of the effects of tax reforms. Overall, our review suggests that at least the direction of the short‐run and long‐run growth effects can be predicted with a reasonable degree of certainty, but there is disagreement with respect to the magnitude. Our review also suggests that depending on the tax change, trade‐offs between short‐run stabilization and long‐run growth may arise and that more research on this question is needed.

Austerity and Exports

Recent papers have focused attention on the potential for expansionary austerity (i.e. that cutting budget deficits may increase growth in the short run). In this paper we investigate the impact of fiscal consolidation on trade using bilateral trade data. The use of bilateral trade data allows us to demonstrate three novel empirical results. First, while fiscal consolidation is associated with an increase in own‐country exports, it is also correlated to an equal extent with a decrease in foreign‐country exports (i.e. imports); indeed, simultaneous austerity has no statistically significant impact on bilateral trade. Second, the positive effect of austerity on exports disappears when trading partners share a common currency. Third, the increase in exports as a result of austerity is associated entirely with an increase in the range of goods exported (the extensive margin), at the expense of trade volume among existing trade relationships (the intensive margin).     

Macroeconomic effects of structural reforms and fiscal consolidations: Trade-offs and complementarities

This paper studies the impact of product and labour market structural reforms and the effects of their joint implementation with alternative debt consolidation strategies. The set-up is a dynamic general equilibrium model calibrated for the Greek economy. The results show that structural reforms produce important long-run GDP gains that materialize earlier, the faster the reforms are implemented. When implemented jointly with fiscal consolidations, structural reforms may amplify the short-run costs of fiscal tightening. The GDP dynamics depend on the fiscal instrument used for public debt consolidation. In the long run, however, there are complementarity gains irrespective of the fiscal instrument used.     

Why Subsidise Private Health Insurance?

What are the economic rationales for the public subsidy of private health insurance? Inducing more people to purchase private cover has the potential to create a positive fiscal externality, as it frees up the limited public beds and other public resources for people who cannot afford private health insurance. Investigating this quantitatively, based on short‐run demand estimates, we find that the subsidy cannot be justified on the basis of this externality effect alone. We estimate that the optimal subsidy is actually negative, that is, a tax on private health insurance premiums. On the other hand, the externality does finance some of the costs. We then consider a long‐run dynamic version, consistent with the government's stated rationales for the reforms. In this context, the subsidy might be justified, or at least largely offset, by the fiscal externality. We then discuss other rationales for a subsidy and implementation issues.     

Fiscal consolidation and financial reforms

We use a rare events logistic regression model as well as traditional probit and logit models to investigate the impact of fiscal consolidation on the likelihood of financial reforms for a panel of 17 countries over the period 1980–2005. We show that large austerity plans, mainly implemented through spending cuts rather than tax hikes, promote financial reforms. By considering reforms affecting specific areas of the financial sector, we find that the banking sector reforms and domestic finance reforms are more likely to occur when fiscal adjustments are put in place. Interestingly, while banking sector reforms are mainly prompted during periods of tax-driven consolidations, spending cuts driven consolidation packages seem to propel the implementation of domestic finance reforms. Finally, we show that higher inflation, lower degree of trade openness, a deterioration of financial conditions and, to some extent, a fall in the degree of competitiveness enhance the probability of financial reforms.     

A TALE OF TAX POLICIES IN OPEN ECONOMIES

To evaluate fiscal policy reforms for Euro‐area countries, this article develops and calibrates a small open economy model. Debt reduction reforms require higher tax rates in the short term in exchange for lower rates in the long term as the debt‐servicing burden falls. Using the capital income tax to implement such a policy leads to welfare gains; the consumption tax, a very small welfare gain; and the labor income tax, a welfare loss. Holding fixed the long‐run debt–output ratio, offsetting a lower capital income tax with either a higher labor income or consumption tax generally yields welfare gains.     

The Impact of Trade Liberalization on Enterprises in Small Backward Economies: the Case of Chad and Gabon

This paper examines the impact of trade and fiscal reforms and of the 1994 devaluation of the CFA franc on enterprise development in Chad and Gabon. These reforms provide a natural experiment to assess the impact of trade liberalization in countries with a small and backward manufacturing sector. The empirical analysis is based on a new panel data base covering virtually the whole population of manufacturing firms in Chad and Gabon, and containing data spanning from the year before to two years after the reforms. The paper finds that although firms’ response to changing incentives was non‐negligible, with a shift of output from nontradable to tradable and an increase in productivity, the reform process was unable to generate a virtuous and self‐sustained circle, where export expansion brings a generalized productivity increase which in turn feeds on further export growth.     

The political economy of trade and migration: Evidence from the U.S. Congress

We compare the drivers of U.S. congressmen's votes on trade and migration reforms since the 1970s. Standard trade theory suggests that trade reforms that lower barriers to goods from less skilled‐labor abundant countries and migration reforms that lower barriers to low‐skilled migrants should have similar distributional effects, hurting low‐skilled U.S. workers while benefiting high‐skilled workers. In line with this prediction, we find that House members representing more skilled‐labor abundant districts are more likely to support trade and migration reforms that benefit high‐skilled workers. Still, important differences exist: Democrats are less supportive of trade reforms than Republicans, while the opposite is true for migration reforms; welfare state considerations and network effects shape votes on migration, but not on trade.     

OPTIMAL FISCAL POLICY IN THE DESIGN OF SOCIAL SECURITY REFORMS*

The quantitative literature has documented that a privatization of the social security system generates large long‐run welfare gains at the cost of welfare losses for transition generations. In this article, we maximize over the entire policy space, following the optimal fiscal policy approach. The resulting allocation, by construction, lies on the constrained Pareto frontier. We find that the optimal design of reforms exhibits sizeable welfare gains arising from a reduction in labor supply distortions. In contrast, the welfare gains coming from the reduction of savings distortions are relatively small.     

Financing government investment and its implications for public capital: A small open economy perspective

Expenditure reductions played a key role in many small open economies during fiscal consolidation, with large declines in public investment. This led to a reduction in public capital stock and affected the competitiveness of these economies. After the sovereign debt crisis, the governments that consider increasing investment to replenish the public capital stock have limited fiscal space and have to avoid external imbalances. We show that using budget-neutral investment spending can generate long-term benefits of higher public capital stock while at the same time limiting negative consequences for the public finances and the trade balance. The best way of financing government investment, which preserves fiscal and trade balances, and increases welfare, is by reducing other government spending. The second-best is financing investment with value-added tax. Financing with debt worsens fiscal and trade balances, while using distortionary labour taxes reduces labour supply, increases wage costs and worsens the trade deficit in the short run.     

EVALUATING THE DISTRIBUTIONAL EFFECTS OF FISCAL POLICIES USING QUANTILE REGRESSIONS

The objective of this paper is to propose and apply a new method to evaluate the distributional impact of fiscal policies and potential marginal reforms. The econometric tool adopted is structural quantile treatment effects regression, which allows a complete picture of the effects of the fiscal policy of interest on households with different incomes, abilities, and needs. We apply this method to personal income taxation and non‐cash transfers in Italy for the year 2004. Our estimates suggest that, although heterogeneous, the redistributive effects of the potential fiscal reforms are almost zero.     

PUBLIC FINANCE AND INDIVIDUAL PREFERENCES OVER GLOBALIZATION STRATEGIES

Do preferences toward globalization strategies vary across public‐finance regimes? In this paper, we use data on individual preferences toward immigration and trade policy to examine how pre‐tax and post‐tax cleavages differ across globalization strategies and state fiscal jurisdictions. High exposure to immigrant fiscal pressures reduces support for freer immigration among U.S. natives, especially the more skilled. The magnitude of this post‐tax fiscal cleavage is comparable to the pre‐tax labor‐market effects of skill itself. There is no public‐finance variation in opinion over trade policy, consistent with U.S. trade policy having negligible fiscal‐policy impacts. Public finance thus appears to shape opinions toward globalization strategies.     

A Factor Endowment Theory of Endogenous Growth and International Trade

This paper presents a dynamic general equilibrium model of multi‐country, two‐good and two‐factor, in which both long‐run growth and international trade patterns are examined. In each country, government expenditure on a public intermediate good plays a crucial role in the realization of persistent growth. It is shown that the long‐run pattern of international trade is determined in a Heckscher‐Ohlin manner.     

Fiscal Policy in a Growing Economy with Financial Frictions and Firm Heterogeneity

This paper constructs a tractable model of endogenous growth with financial frictions and firm heterogeneity. We introduce factor income tax, consumption tax as well as the government consumption into the base model and explore the growth effect of fiscal policy. We show that from the qualitative perspective, the long‐run effects of fiscal actions in our model are similar to those obtained in the representative agent models. However, the quantitative impacts of fiscal policy on long‐run growth in our setting can be substantially different from those established in the model where agents are homogeneous and there is no financial frictions.     

Spillover effects of fiscal policy in a monetary union: Why do fiscal instruments matter?

Using a two‐country DSGE model, we analyse the spillover effects of fiscal policy in a monetary union. Based on a non‐Walrasian labour market with a labour force participation decision and involuntary unemployment and a detailed fiscal sector, we focus on the relative cross‐border effects of different kinds of fiscal shocks (government expenditure and tax shocks). Among the major lessons from this analysis, five general and striking results are worth highlighting : (1) spillover effects differ widely according to the fiscal instrument, (2) all fiscal instruments produce positive spillover effects on foreign GDP except a rise in government consumption, (3) the response of unemployment is not always negatively correlated with the response of output (4) the different fiscal shocks trigger different effects on foreign inflation and the term of trade, which implies heterogeneous interest‐rate and trade channels, and (5) a more accommodative monetary policy and a scenario of ‘fiscal dominance’ alter greatly the effects of fiscal policy shocks.     

The Malaysian Real Trade Balance and the Real Exchange Rate

The cointegration technique is used to examine the long‐run and short‐run relationships between the real Malaysian trade balance with the real exchange rate, domestic and world incomes. The results suggest that a real ringgit exchange rate depreciation improves the trade balance in the long run. World and domestic incomes are also found to be important determinants of trade balance. The significance of world income on trade balance indicates that Malaysia is prone to external shocks. An error‐correction model is then estimated to study the short‐run dynamics of the effects of exchange rate. The impulse response analysis shows that the effect of exchange rate on the trade balance lasts for about three years. A devaluation of ringgit will initially improve the trade balance, albeit small, after which the trade balance starts to deteriorate, and then improves again suggesting that there exists a delayed J‐curve.     

Long‐run Lunacy,Short‐run Sanity: a Simple Model of Trade with Labor Market Turnover*

It is often argued that international trade is all about long‐run relationships. In this paper, we argue that this view is flawed when factor markets are characterized by turnover. Toward that end, we provide a simple dynamic model of trade with labor market turnover and show that the relationship between the economy's short‐run and long‐run behavior is more complex than in traditional trade models. For example, in the short run, the economy may produce outside of its long‐run frontier. We show that focusing on long‐run relationships can lead one to draw faulty policy conclusions, while focusing on its short‐run behavior restores sanity. The implication is that in the presence of factor market turnover, international trade issues can only be understood by studying the entire dynamic path of the economy. Long‐run relationships should be ignored.
