Bank risk and non-interest income activities in the Indonesian banking industry

The recent trend of product diversification in the Indonesian banking industry underscores the importance of non-interest income activities. This study examines the relationship between product diversification and bank risk over the period of 2002–2008. Our analysis shows clear evidence that the effect of product diversification on bank risk depends highly on the bank's asset size. Specifically, the degree of product diversification is negatively associated with bank risk for small-sized banks. Conversely, the degree of product diversification is positively related to bank risk for large-sized banks. This finding suggests that deregulation encouraging banks to become more involved in non-traditional activities may have an adverse effect on the overall banking system where large-sized banks are playing a significant role in Indonesia.     

Extensions of linear diagonal-parameter symmetry and quasi-symmetry models for cumulative probabilities in square contingency tables

For square contingency tables with ordered categories, CAUSSINUS [Annales de la Faculté des Sciences de l'Université de Toulouse (1965) Vol. 29, pp. 77–182] and AGRESTI [Statistics and Probability Letters (1983) Vol. 1, pp. 313–316] considered the quasi-symmetry and the linear diagonal-parameter symmetry models, respectively, which have multiplicative forms for cell probabilities. This paper proposes two kinds of models that have the similar multiplicative forms for cumulative probabilities that an observation will fall in row (column) category i or below and column (row) category j (> i ) or above. The endometrial cancer data are analyzed using these models.     

Productivity growth,on-the-job search,and unemployment

The impact of long-run productivity growth on unemployment is studied. We incorporate disembodied technological progress and on-the-job search into the endogenous job separation model of Mortensen and Pissarides (1994). Because we include on-the-job search, faster growth reduces unemployment by decreasing job separation and inducing job creation. The incorporation of on-the-job search substantially improves the ability of the Mortensen and Pissarides model to explain the effect of growth on labor market variables. Specifically, our model generates not only an empirically consistent sign of the effect, but also a larger impact of growth on unemployment than the standard matching model.     

Gross worker flows and unemployment dynamics in Japan

This paper studies the dynamics of worker flows in Japan between 1980 and 2009. We construct gross worker flows data using the monthly Labor Force Survey. Our data enables us to examine the size and cyclical patterns of the flows and transition rates between employment, unemployment, and not being-in-the labor force. We find that the cyclical pattern of worker flows is similar to that found in other countries; however, worker flows in Japan are generally smaller than those in the US and European countries. We also decompose changes in unemployment into contributions from unemployment inflow and outflow rates. We find that both inflow and outflow rates significantly affect variations in unemployment.     

Macroeconomic Policy and Ownership Structure in a Mixed Transition Economy

Both state and non-state sectors have important roles in the Chinese economy. A dynamic model to analyze capital accumulation in state and non-state sectors is constructed and the fiscal and monetary policy requirements for the coexistence of a state sector and a non-state sector are derived. Our findings suggest that the effects of fiscal and monetary policies on ownership structure depend on which government subsidization policy is implemented. The results indicate that lowering tax rates and tightening the money supply can speed up the transition pace, but these policies do not necessarily contribute to developing an economy with a greater share for the non-state sector.J.

STRATEGIC INVESTMENT IN A LABOUR‐MANAGED DUOPOLY

Developing a Cournot two‐stage game model with strategic capital interaction, we compare two different kinds of equilibrium in a labour‐managed (LM) duopoly. An LM firm's reaction function is negatively sloped when capital and output are simultaneously determined, while the slope of its reaction function in the second stage changes in sign depending on the magnitude of its labour‐expansion elasticity. Hence, whether the LM firms employ more capital and produce greater output at the equilibria in the two‐stage game model than at the equilibria resulting from the simultaneous selection of capital and output depends on the magnitude of their labour‐expansion elasticity.     

Filial Obligations and Child Labor

The model presented here reproduces the empirical fact that poorer countries show a higher incidence of child labor and time‐intensive care of retired parents, whereas richer countries have negligible child labor and people indulge in money‐intensive care of the old. For that purpose, the effect of social norms of filial obligations on child labor and schooling decisions is analyzed. It is shown that norms of filial obligations are sustainable as an equilibrium in the intergenerational game. Widely discussed contracting problems à la Becker, which allegedly explain underinvestment in schooling by poor households, are thus solved. However, this alone does not induce the elimination of child labor. Technological parameters and relative returns to schooling also play a fundamental role.
