A dynamic general equilibrium model for public R&D investment in Taiwan

In terms of economic development policies, public research and development (R&D) investment may be one of the most critical and useful tools in Taiwan, having frequently played a role in leading related overall investment in Taiwan. Although the impact channels of R&D investment are varied and complex, its benefits in terms of the development of human capital, industrial productivity, and basic research are clear. With the rapid growth of the private sector in the Taiwan economy, it is, however, debatable whether the government should continue to use the public financial budget to invest in R&D. By using a computable general equilibrium (CGE) model to simulate the impact of public R&D investment on the economy in Taiwan, the empirical evidence of the present paper is that public R&D investment gives rise to different short-term and medium-term impacts on real GDP that are mostly felt in the third or fourth years of their implementation among different industries. These impacts then gradually converge back to equilibrium in the long run. Public R&D investment boosts the technology of high-tech industries and increases exports, but it also crowds out the output of primary industries. Although the public R&D investment has a positive effect on the real wage, its effect on inflation should not be overlooked. Because of the pros and cons surrounding the impact of public R&D investment on industries and the economy, the study provided by the present paper can serve as valuable reference not only to decision-makers in government agencies but also to academic researchers.     

Welfare and equity impacts of cross-border factor mobility in Bangladesh: A general equilibrium analysis

We develop a dynamic computable general equilibrium model with cross-border factor mobility to assess the impacts of a foreign wage shock and the effects of counteractive policy measures in Bangladesh. The model features migration of workers and foreign direct investment (FDI) in the ready-made garments (RMG) sector. Our simulation results show that returning migrants induced by a foreign wage fall would reduce household welfare by lowering wages and increasing unemployment, particularly for unskilled workers in the domestic labor market. To counteract this negative shock, FDI promotion in the RMG sector and a human-capital development program are considered. The former policy minimizes the negative impacts of the foreign labor market shock, while a combination of both policies is more equitable.     

Skilled-unskilled wage inequality and unemployment: A general equilibrium analysis

The paper develops a static three sector competitive general equilibrium model of a small open economy in which skilled labor is mobile between a traded good sector and the non-traded good sector and unskilled labor is specific to another traded good sector. Capital is perfectly mobile among all these three sectors. We introduce involuntary unemployment equilibrium in both the labor markets and explain unemployment using efficiency wage hypothesis. We examine the effects of change in different factor endowments and prices of traded goods on the unemployment rates and on the skilled-unskilled relative wage. Also, we introduce Gini-Coefficient of wage income distribution as a measure of wage income inequality; and show that a comparative static effect may force the skilled-unskilled relative wage and the Gini-Coefficient of wage income distribution to move in opposite directions in the presence of unemployment.     

Welfare effects of 1992: A general equilibrium assessment for EC and EFTA countries

In this paper production, trade and welfare effects of European integration are discussed, with particular emphasis on the effects for the EC and EFTA. Insights from previous partial and general equilibrium analyses of the internal market are reviewed, and new model simulations are presented. In addition to the standard experiments of 1992 — as reduced trade costs and as full market integration — for the EC alone, and for the European Economic Area (EEA), an intermediate case, with full integration in the EC but only lower trade costs between the EC and EFTA, is analysed. All cases show that EFTA will benefit significantly from freer trade and closer integration with the EC. With regard to non-European regions, the simulations of European integration show some degree of trade diversion, but stylized model experiments indicate that a successful outcome of the Uruguay-round may more than offset the trade-diverting effects of 1992.     

Structural reforms,fiscal consolidation and external rebalancing in monetary union: A model-based analysis

The paper analyses the impact of structural reforms on external positions in monetary union in a 3-region version of QUEST III. Wage cost moderation and fiscal consolidation improve the current account balance in the medium term, but positive income effects tend to offset the initial increase in the long term. The general pattern is robust across alternative levels of initial foreign indebtedness. While lasting imbalance correction requires a contraction of debt-financed domestic demand, supply-side reform can mitigate the associated output contraction. A scenario is given as illustration that would reverse the 20% competitiveness loss in the EMU periphery during the 2000s and reduce foreign and government debt by 30% and 50% of GDP within ten years.     

Land reforms and social unrest: An empirical investigation of riots in India

This paper considers the effect of agrarian reforms on rioting in India. I find that the adoption of agrarian reforms was associated with a decline in the overall riot rate but the Hindu-Muslim riot rate, an urban phenomenon was largely unaffected by the program.     

Inequalities and fluctuations in a dynamic general equilibrium model

   Summary. In the present paper a tractable two-sector neo-classical growth model with heterogeneous agents is considered. The local dynamic properties of the equilibrium path are analyzed in relation with the underlying characteristics of the economy. In particular, the existence of fluctuations is related to the degree of heterogeneity in labor and in capital endowments. When applied to international trade theory, the analysis shows that free trade may distabilize a world economy that is originally stable under the regime of autarky.

A three state model of worker flows in general equilibrium

We develop a simple model featuring search frictions and a nondegenerate labor supply decision along the extensive margin. The model is a standard version of the neoclassical growth model with indivisible labor and idiosyncratic productivity shocks and frictions characterized by employment loss and employment opportunity arrival shocks. We argue that it is able to account for the key features of observed labor market flows for reasonable parameter values. Persistent idiosyncratic productivity shocks play a key role in allowing the model to match the persistence of the employment and out of the labor force states found in individual labor market histories.     

A general equilibrium model of structural change and economic growth,with application to south Korea

This paper presents a computable general equilibrium model for South Korea. It is a dynamic input-output model solved by assuming equal sectoral growth rates. Its solution gives output and price relatives which measure the structural ‘distance’ of the economy from the ‘turnpike’. Comparisons of these model solutions with actual output proportions and relative prices provide insights into the South Korean industrialization process. However, the model's strict assumptions limit its applicability and provide problems of interpretation, especially in open economies.     

Optimal labor income taxation in a two-sector dynamic general equilibrium model

This paper presents a new approach to the two-sector optimal taxation problem. We derive the optimal labor income tax rate which depends on factor intensity across sectors. It is the labor intensity that determines the initial wage rate, and therefore the optimal labor tax rate. We show that an increase in the initial relative price of consumption goods decreases the optimal tax rate on labor income in the case that the consumption goods sector is capital-intensive while it increases the optimal tax rate on labor income in the case that the investment goods sector is capital-intensive.     

Fiscal policy reforms in general equilibrium: The case of Greece

This paper quantifies the macroeconomic and welfare implications of (i) changes in the tax-spending mix and (ii) debt consolidation policies. The setup is a neoclassical growth model augmented with a relatively rich public sector. The model is calibrated to the Greek economy. The results suggest that, if the goal of fiscal policy is to stimulate the economy and increase welfare by changing the tax mix, then it should decrease the tax rate on labour income and increase the consumption tax rate. While higher public investment spending is good for the economy, it is lower public consumption spending that is found to be expansionary. The results also suggest that both tax- and expenditure-based debt consolidation policies lead to worse economic activity in the short run, but they have strong beneficial effects in the medium and long run when the consolidation period finishes.     

The use of trade measures against illicit fishing: Economic and legal considerations

Illegal, Unreported and Unregulated (IUU) fishing activities are a threat for both the marine environment and society. By undermining effective management systems, IUU fishing activities affect economic performance, social welfare and compliance decisions. So far, “traditional” control and surveillance-like measures have had a limited success in deterring IUU fishing, so this paper aims at throwing light on several forms of trade-related initiatives that can be more effective. The paper suggests that both the effectiveness and further development of such measures strongly depend on the way they are designed, especially with respect to their trade-law compatibility. However, current discussions on future trade-based policy developments within some key economic areas suggest that trade measures are a sound option for policy makers. While the paper focuses on fisheries issues, it is also expected to inform the international debate surrounding the sustainable use of natural resources in general, as many sectors face similar biodiversity and trade challenges (e.g. tropical forest, mangroves, etc.).     

Destabilization effect of international trade in a perfect foresight dynamic general equilibrium model

In the present paper, we consider a two-country, two-good, two-factor general equilibrium model with CIES nonlinear preferences, asymmetric technologies across countries and decreasing returns to scale. It is shown that aggregate instability and endogenous fluctuations may occur due to international trade. In particular, we prove that the integration into a common market on which countries trade the produced good and the capital input may lead to period-two cycles even when the closed-economy equilibrium is saddle-point stable in both countries.     

Capital taxation in a dynamic general equilibrium setting

The familiar two-factor, two-commodity incidence model is extended to a dynamic setting in which the supply of capital is variable and the government can use money or bonds to balance its budget in addition to neutral lump sum taxation. The dynamic incidence effects of a sectoral tax on capital are qualitatively similar to the static incidence effects when the government balances its budget with neutral taxes, but are qualitatively different when the government uses money or bonds. In this case, while capital bears the burden of the tax in the short run, it is able to shift it in the long run.     

A general equilibrium open economy model for emerging markets: Monetary policy with a dualistic labor market

An optimizing model of a small open emerging market economy (SOEME) with dualistic labor markets and two types of consumers, delivers a tractable model for monetary policy. Differences between the SOEME and the SOE are derived. Parameters depend on features of the labor market and on consumption inequality, and affect the natural interest rate, terms of trade and potential output. The supply curve turns out to be flatter and more volatile, with a larger number of shift factors, including policy-determined terms of trade. A simple basic version of the model is simulated in order to compare different policy targets in response to a cost shock. Flexible domestic inflation targeting gives the lowest volatility although there are trade-offs. Exchange rate volatility is relatively lower but still makes a major contribution to controlling inflation. Flexible CPI inflation targeting performs better when combined with some kind of managed floating. Inflation targeting has to be flexible. With more backward-looking behavior the policy response to a shock is reduced.     

Stock exchange mergers and return co-movement: A flexible dynamic component correlations model

The creation of a common cross-border stock trading platform is found, by use of a Flexible Dynamic Component Correlations (FDCC) model, to have increased long-run trends in conditional correlations between foreign and domestic stock market returns.     

Worker remittances,migration, accumulation and growth in poor developing countries: Survey and analysis of direct and indirect effects

A broad but brief survey of the literature on remittances and growth shows that indirect effects are only included via interaction terms. Then, we regress data for migration, worker remittances, savings, investment, tax revenues, public expenditure on education, interest rates, literacy, labor force growth, development aid and GDP per capita growth on migration, remittances and other variables for a panel of countries with income below $1200. The estimated dynamic equations are integrated to a system used for baseline simulations. Comparison with the counterfactual policy simulations ‘only 50% remittances’ or ‘no net migration anymore’ shows that the total effect of remittances on levels and growth rates of GDP per capita, investment and literacy are positive, and that of net migration is negative for literacy and investment but positive for growth.     

Neckties in the tropics: a model of international trade and cultural diversity

Abstract .  Some cultural goods are consumed socially and are characterized by the same consumption network externalities as languages. Also, producers of new cultural goods in any one country draw on the stock of ideas generated by previous cultural production in all countries. For such goods, costless trade and communication tend to lead to the dominance of one cultural style, increasing utility in the short run but reducing quality and welfare in the long run. Increasing protection while keeping communication costs low may stimulate production of cultural goods that are 'compatible' with the dominant style, adding little to the stock of usable ideas.
