A SEARCH FOR CLOSER ECONOMIC RELATIONS IN EAST ASIA

In recent years, growing interdependence in East Asia through trade and financial cooperation heightened the need for East Asian Economies to engage in closer regional economic relations. This paper attempts to discuss emerging economic integration efforts in East Asia with special reference to bilateral and regional free trade agreements. It discusses backgrounds for recent developments of East Asian regionalism in terms of deepening intraregional economic dependence and financial cooperation, and South Korea's position towards FTAs with major trading partners as well as East Asian economic integration. Important issues and challenges for an East Asian FTA are presented.     

RESEARCH AND DEVELOPMENT IN SMALL AND MEDIUM-SIZED ENTERPRISES: THE ROLE OF FINANCIAL CONSTRAINTS AND PUBLIC FUNDING

This paper presents microeconometric evidence on financing constraints for research and development activities in German small‐ and medium‐sized firms (SME). Special attention is paid to the role of public research and development (R&D) subsidies. For this purpose SMEs in West and East Germany are compared because these regions are very different in their supply of public R&D funding. The empirical evidence suggests that West German SMEs are financially constrained in their R&D activities by both internal and external resources. In East Germany, firms are not sensitive to external constraints, possibly due to high public R&D subsidies. The results show that R&D in East Germany is to a large extent driven by public subsidies and that the usual financial market mechanisms are dysfunctional with respect to R&D in this region.     

Estimating spatial differences in the Brazilian cost of living with household location choices

This paper uses a model of optimal household residential decisions to construct a comprehensive “true” spatial cost of living index with readily available Brazilian census data. We find evidence of a decreasing or U-shaped relationship (differing with education level and region) between the cost of living and urbanization, suggesting that both market disintegration and congestion play roles in raising costs. Controlling for spatial differences in the cost of living is shown to have important consequences for the determinants of poverty and (contrary to many previous results) to increase income inequality.     

Child labor,urban proximity,and household composition

Using detailed survey data from Nepal, this paper examines the determinants of child labor with a special emphasis on urban proximity. We find that children residing in or near urban centers attend school more and work less in total but are more likely to be involved in wage work or in a small business. The larger the urban center, the stronger the effect is. Urban proximity is found to reduce the workload of children and improve school attendance up to 3 h of travel time from the city. In areas of commercialized agriculture located 3 to 7 h from the city, children do more farm work. Urban proximity effects are accounted for by a combination of local labor supply and demand conditions, most notably the local importance of agriculture, the education level of the parents, and the local wage rate. Child servants, which represent a small proportion of all children, work much harder than other children and appear particularly at risk.     

Quality dualism

We suggest a theory of quality dualism, defined in terms of the gap between the highest quality good produced in the informal sector and the lowest quality produced in the formal sector. We develop a model of vertically differentiated products, in which firms producing in the formal and informal sectors face different factor prices, and have a relative advantage in the manufacture of different qualities. We then use the model to examine the cyclical behavior of the respective sizes of the two sectors. Finally, we point out that factor price changes, which reduce or increase the size of the informal sector, may have the same or opposite effect on the degree of dualism in the economy.     

Effective property rights, conflict and growth

This paper shows how the interaction between conflict and growth can give rise to a nonmonotone relationship between property rights and social welfare. This interaction is illustrated in a model of endogenous growth in which equilibrium diversion of resources is the cost of securing effective property rights. A symmetric equilibrium allocation associated with more secure property rights and faster growth can be Pareto dominated by one associated with poorer property rights and slower growth. Faster growth can exacerbate the problem of diversion whenever property rights are sufficiently poor. These results call for caution before a society decides to pursue economic growth independently of the institutional structure of property rights. Furthermore, if this structure is inappropriate piecemeal reform might not be in the interest of society, and a substantial reform might be necessary if it is to be welfare-improving.

Optimal monetary policy with the cost channel

In the standard new Keynesian framework, an optimizing policy maker does not face a trade-off between stabilizing the inflation rate and stabilizing the gap between actual output and output under flexible prices. An ad hoc, exogenous cost-push shock is typically added to the inflation equation to generate a meaningful policy problem. In this paper, we show that a cost-push shock arises endogenously when a cost channel for monetary policy is introduced into the new Keynesian model. A cost channel is present when firms’ marginal cost depends directly on the nominal rate of interest. Besides providing empirical evidence for a cost channel, we explore its implications for optimal monetary policy. We show that its presence alters the optimal policy problem in important ways. For example, both the output gap and inflation are allowed to fluctuate in response to productivity and demand shocks under optimal monetary policy.     

The learning cost of interest rate reversals

Many central banks in many time periods have sought to avoid interest rate reversals, but at present there is no good explanation of this phenomenon. Our analysis identifies a new learning cost associated with reversing the interest rate. In a standard monetary model with forward-looking expectations, data uncertainty and parameter uncertainty, a policy that frequently reverses the interest rate makes learning the key parameters of the model more difficult. Optimal monetary policy internalises this learning cost and therefore has a lower number of interest rate reversals.
