Energy‐Related Environmental Policy and Its Impacts on Energy Use in Asia

Economic growth in Asia has increased in the past three decades and has heightened energy demand, resulting in rising greenhouse gas emissions and severe air pollution. To tackle these issues, fuel switching and the deployment of renewables are essential. In the present paper, we discuss the environmental regulations, mainly carbon pricing, implemented in Asia and discuss their achievements. Empirical studies using microdata have shown that carbon pricing in Asia can reduce carbon emissions by promoting energy efficiency. At the macro level, we observe some evidence of fuel switching from coal to natural gas among major emitters. However, more carbon pricing is necessary in Asia if we aim for the decarbonization of the economy.     

A Note on Environmental Awareness and Cross-Border Pollution

Considering a Nash equilibrium in which a developed country chooses the amount of foreign aid and a developing country sets the emission tax rate and the proportion of the received aid allocated to public abatement of pollution, it is shown that an increase in the recipient countrys environmental awareness will reduce the level of cross-border pollution and benefits the donor though its foreign aid is increased.     

Ergodic chaos in optimal growth models with low discount rates

Summary We show that for every discount factor(0,1) one can find infinitely many strictly concave discrete-time optimal growth models in reduced form which have optimal policy functions exhibiting ergodic chaos. These reduced form models are interpreted in a two-sector optimal growth setting with utility functions depending on consumption as well as on capital.We thank Luigi Montrucchio for pointing out an error in a previous version of the paper.

Is a Big Entrant a Threat to Incumbents? The Role of Demand Substitutability in Competition Among the Big and the Small

We establish a model of market competition between large and small firms and investigate the way in which demand substitutability affects how the entry of big firms impacts incumbents. We focus on the relative strength of two opposing effects of entry on large incumbent firms’ demand: the direct substitution effect among large firms (negative) and the indirect feedback effect through the change in small firms’ aggregated behavior (positive). If the substitutability between large and small firms is sufficiently high, the indirect effect dominates the direct effect and large incumbents’ equilibrium prices and profits increase. We show that welfare effects are ambiguous, which calls for careful assessment when regulating large firms’ entry.     

Instructional skills for on‐the‐job training and experiential learning: an empirical study of Japanese firms

Despite the effectiveness of on‐the‐job training (OJT), few systematic empirical studies have been conducted on how OJT trainers instruct trainees in firms. The primary goal of this study was to investigate the characteristics of the trainer's instructional skills for OJT using survey data collected from 715 employees covering 22 firms. Results indicate that excellent OJT trainers use four types of instructional skills: (1) stretching trainee objectives, (2) monitoring their progress, (3) providing positive feedback, and (4) promoting reflection on results. The findings suggest that excellent OJT trainers facilitate trainees' experiential learning by promoting deliberate practice and reflective practice. Theoretical and managerial implications are also discussed.     

Collateral fluctuations in a monetary economy

This paper studies economy-wide fluctuations that occur endogenously in the presence of monetary and real assets. Using a standard monetary search model, we consider an economy in which agents can increase consumption, over and above what their liquid monetary asset holdings would allow, pledging real assets as collateral for monetary loans. It is shown that, if the liquidation value of real assets is below full market value, a stable cyclical equilibrium can emerge in consumption and capital around the unstable steady state. We also provide conditions for the existence of cycles of higher order, chaos and sunspot equilibria.     

On the Uniqueness of the Welfare–maximizing Number of Firms Under Cournot Oligopoly

Under Cournot oligopoly with a homogeneous product, we present a sufficient condition that guarantees the uniqueness of the welfare–maximizing number of firms to attain the global maximum level of welfare by implementation of a piecemeal policy changing the number of firms gradually. We adopt Selten's (1973) 'fitting–in function' method, which relates an individual firm's output to an industry's output. When the number of firms is unique, then introducing a lump–sum profit tax (subsidy) can attain the optimal level of welfare. Indirect entry regulation is superior to direct entry regulation from the standpoint of welfare if each entrant engages in rent–seeking activities.
