Japanese Banks’ monitoring activities and the performance of borrower firms: 1981–1996

We construct an index measure that quantitatively describes the monitoring activities of Japanese banks. Using micro data on Japanese banks and borrower firms, we examine the effects of bank monitoring on the profitability of borrower firms. We find significant positive effects in the periods 1986–1991 and 1992–1996, although there is no significant effect in the period 1981–1985. We also examine how banks’ monitoring affects borrowers. The results show that the positive effects of banks’ monitoring on borrowers’ profitability are mostly caused by screening effects, not performance-improving effects.

Are cooperative firms a less competitive form of business? Production efficiency and financial viability of cooperative firms with tradable membership shares

Cooperative firms are generally considered a less competitive form of business than conventional capitalist firms in a market system. In this study, we consider cooperative firms that issue tradable membership shares and show that they are in principle as efficient and financially viable as capitalist firms. This implies that, if allowed to issue tradable membership shares, cooperative firms could be a promising alternative to capitalist firms in a wider range of circumstances.     

Is FTA/EPA effective for a developing country to attract FDI? The knowledge‐capital model revisited

To prepare an answer to the question of how a developing country can attract foreign direct investment (FDI), this paper explored the factors and policies that may help bring FDI into a developing country by utilising an extended version of the knowledge‐capital model. With a special focus on the effects of a free trade agreement (FTA) or an economic partnership agreement (EPA) between a pair of market and non‐market countries, simulations with the model revealed the following: (i) although FTA/EPA generally tends to increase FDI to a developing country, the possibility of improving welfare through increased demand for skilled and unskilled labour decreases as the size of the country grows; (ii) a developing country may suffer severe welfare losses through FTA/EPA if the availability of skilled labour is extremely limited; and (iii) a developing country can enhance welfare gains from a FTA, and it is even possible to recover the welfare effects from negative to positive, by making the arrangement an EPA.     

Taxing multinationals: The scope for enforcement cooperation

Policymakers seeking to raise more tax revenues from multinational enterprises have two alternatives: to raise tax rates or to devote more resources to improve tax compliance. Tougher tax enforcement increases the cost of profit shifting, and thus mitigates tax competition. We present a tax-competition model with two policy instruments (the corporate tax rate and the tightness of tax enforcement). In line with the Organisation for Economic Cooperation and Development's Base Erosion and Profit Shifting project, we analyze the scope for enforcement cooperation among asymmetric countries, considering that taxes are set noncooperatively. We show that the low-tax country may fail to cooperate if asymmetry is large enough and that tax havens would never agree to cooperate. Then we identify two drivers for enforcement cooperation. The first driver of cooperation is the complementarity of enforcement actions across countries. This is because the efficiency loss from enforcement dispersion is greater under complementarity. The second driver of cooperation is tax leadership by the high-tax country, which acts as a level-playing field in the tax competition and reduces the extent of disagreement on enforcement.     

Asymptotic properties of the efficient estimators for cointegrating regression models with serially dependent errors

In this paper, we analytically investigate three efficient estimators for cointegrating regression models: Phillips and Hansen’s [Phillips, P.C.B., Hansen, B.E., 1990. Statistical inference in instrumental variables regression with I(1) processes. Review of Economic Studies 57, 99–125] fully modified OLS estimator, Park’s [Park, J.Y., 1992. Canonical cointegrating regressions. Econometrica 60, 119–143] canonical cointegrating regression estimator, and Saikkonen’s [Saikkonen, P., 1991. Asymptotically efficient estimation of cointegration regressions. Econometric Theory 7, 1–21] dynamic OLS estimator. We consider the case where the regression errors are moderately serially correlated and the AR coefficient in the regression errors approaches 1 at a rate slower than 1/T$1/T$, where T$T$ represents the sample size. We derive the limiting distributions of the efficient estimators under this system and find that they depend on the approaching rate of the AR coefficient. If the rate is slow enough, efficiency is established for the three estimators; however, if the approaching rate is relatively faster, the estimators will have the same limiting distribution as the OLS estimator. For the intermediate case, the second-order bias of the OLS estimator is partially eliminated by the efficient methods. This result explains why, in finite samples, the effect of the efficient methods diminishes as the serial correlation in the regression errors becomes stronger. We also propose to modify the existing efficient estimators in order to eliminate the second-order bias, which possibly remains in the efficient estimators. Using Monte Carlo simulations, we demonstrate that our modification is effective when the regression errors are moderately serially correlated and the simultaneous correlation is relatively strong.     

Reallocation and productivity growth in Japan: revisiting the lost decade of the 1990s

Hayashi and Prescott (Rev Econ Dyn 5(1):206–235, 2002) argue that the ‘lost decade’ of the 1990s in Japan is explained by the slowdown in exogenous TFP growth rates. At the same time, other research suggests that Japanese banks’ support for inefficient firms prolonged recessions by reducing productivity through misallocation of resources. Using the data on large manufacturing firms between 1969 and 1996, the paper attempts to disentangle the factors behind the slowdown in productivity growth during the 1990s. The main results show that there was a significant drop in within-firm productivity, the component that is not affected by reallocation of input and output shares across firms over time, during the 1990s. Although we find that misallocation among large continuing firms represents a substantial drag to overall TFP growth for these firms throughout the sample period, the negative impact of misallocation was least visible during the 1990s. The significant reduction in within-firm productivity growth suggests that, as the Japanese economy has matured, a policy which fosters technological innovations via greater competition, R&D, and fast technological adoption may have become increasingly important in promoting economic growth.

The simultaneous berth and quay crane allocation problem

This paper addresses efficient berth and crane allocation scheduling at a multi-user container terminal. First, we introduce a formulation for the simultaneous berth and crane allocation problem. Next, by employing genetic algorithm we develop a heuristic to find an approximate solution for the problem. The fitness value of a chromosome is obtained by crane transfer scheduling across berths, which is determined by a maximum flow problem-based algorithm based on a berth allocation problem solution defined by the chromosome. The results of numerical experiments show that the proposed heuristic is applicable to solve this difficult but essential terminal operation problem.     

Why Does the Problem Persist? ‘Rational Rigidity’ and the Plight of Japanese Banks

One of the most perplexing factors in the Japanese financial crisis is the apparently non‐optimal and non‐rational behaviour of Japanese banks. We provide a “rational” explanation for bank behaviour based on a theory of community banking that incorporates Japanese institutional characteristics. We find three implications of community banking – a low lending rate, a low bankruptcy rate, and in particular, institutionalisation of ‘rational rigidity’ (an institutional pledge of no profit maximisation) – in Japanese banks. We argue that this type of banking is viable as long as the economy expands and asset prices go up, which was the case before the asset‐market crash in 1990. The stagnation and free‐fall of asset prices in the 1990s exerted tremendous pressure on Japanese banks but did not paralyse them completely in the 1990s, although there are indications that they failed to restructure distressed large corporations in some sectors, notably real estate. Thus, the problem is not that paralysed banks are blocking recovery, but that their current institutionalised rigidity in banking practices is no longer viable because private enterprises in the market economy are suffering from asset‐price deflation and economic stagnation.     

Estimating the mark-up over marginal cost: a panel analysis of Japanese firms 1971–1994

In this paper, we propose a new method to estimate mark-ups over marginal cost at the firm level. This method is based on the identity between the short-run elasticity of output to inputs, the mark-up rate, and the factor shares. We then apply this method to a panel of Japanese firms in 21 industries over 24 years. We have three main results. First, there is strong evidence of imperfect competition in this panel, in which internationally competitive industries show low mark-ups. Second, the mark-up rate differs considerably among firms and its distribution is skewed. Third, the mark-up rate over marginal cost shows strong procyclicality, and its sensitivity is uniform within the industry.
