Policy Measures to Alleviate Foreign Currency Liquidity Shortages under Aggregate Risk with Moral Hazard

During the recent global financial crisis, certain central banks introduced two innovative cross‐border operations to deal with the problems of foreign currency liquidity shortages: domestic liquidity operations using cross‐border collateral and operations that supply foreign currency among central banks based on standing swap lines. We show theoretically that central banks improve the efficiency of equilibrium under foreign currency liquidity shortages using these two innovative temporary policy measures.     

On the short-run relationship between the income distribution-growth and debt-growth regimes

This paper examines the short-run relationship between the income distribution-growth and debt-growth regimes using a simple, post-Keynesian, demand-driven model. While mechanisms of wage-led and profit-led growth have been revealed, their relationship with debt-led and debt-burdened growth is yet to be clarified, because arguments on these growth regimes were developed separately. This paper shows that the growth regimes transform as the regime-switching parameters in the IS balance change. By way of theoretical analysis, this paper presents some important implications for (i) the possibility of the combination of growth regimes; (ii) the features of post-Keynesian economic analysis of income distribution, debt, and demand-led growth, which sharply contrast with the basic neo-classical theory; and (iii) theoretical validation of recent empirical results. Moreover, this paper also suggests some policy implications or lessons for the combination of economic growth regimes.     

Non-self-averaging in macroeconomic models: a criticism of modern micro-founded macroeconomics

When the coefficient of variation, namely the ratio of the standard deviation over the mean approaches zero as the number of economic agents becomes large, a system is called self-averaging. Otherwise, it is non-self-averaging. Most economic models take it for granted that the economic system is self-averaging. However, they are based on the extremely unrealistic assumption that all the economic agents face the same probability distribution, and that micro shocks are independent. Once these unrealistic assumptions are dropped, non-self-averaging behavior naturally emerges. Using a simple stochastic growth model, this paper demonstrates that the coefficient of variation of aggregate output or GDP does not go to zero even if the number of sectors or economic agents goes to infinity. Non-self-averaging phenomena imply that even if the number of economic agents is large, dispersion could remain significant, and we cannot legitimately focus solely on the means of aggregate variables. This, in turn, means that the standard microeconomic foundations based on representative agents have little value for they are meant to provide us with accurate dynamics of the means of aggregate variables. Contrary to the main stream view, micro-founded macroeconomics such as a dynamic general equilibrium model does not provide solid micro foundations.     

Defending Home against Giants: Exclusive Dealing as a Survival Strategy for Local Firms*

We consider exclusive contracts a survival strategy for a local incumbent manufacturer facing a multinational manufacturer's entry. Although both manufacturers prefer to trade with an efficient local distributor, trading with inefficient competitive distributors is acceptable only to the entrant, because of the entrant's efficiency. Hence, such competitive distributors can be an outside option for the entrant. As the entrant becomes efficient, the outside option works effectively, implying that the entry does not considerably benefit the efficient local distributor. Thus, the local manufacturer is more likely to sign an anticompetitive exclusive contract with the efficient distributor as the entrant becomes efficient.     

Using managers' expectations for ex-ante policy evaluation: Evidence from the COVID-19 crisis

Evaluation of the impacts of government policies during an economic crisis is often delayed until the outcomes are realized. Policies can be better guided if they can be evaluated amid a crisis, before the realization of outcomes. This study examines whether survey data on the expectations of small business managers can help evaluate two high-stake subsidies for firms amid the COVID-19 crisis in Japan, namely, Subsidy Program for Sustaining Businesses (SPSB) and Employment Adjustment Subsidy (EAS). We evaluate the accuracy of managers' expectations, estimate the impact of subsidies on the expected firm survival, and compare it with the estimated impact on realized survival. We find that the managers' expectations on their future sales, survival rate, and the possibility of receiving these subsidies predict the realized outcomes, although they were highly pessimistic about their survival rates. We find that the estimated impacts of the SPSB on the expected survival rates have the same sign as the estimated impact on the realized survival rates, but the size is more than twice because of the pessimism on survival. The estimated impacts of the EAS are both insignificant. Therefore, although its impact may be overestimated, managers' expectations are useful for selecting an effective policy.     

The magnification effect in global value chains

We examine the “magnification effect,” which demonstrates that as the number of separable production stages increases, trade increases dramatically as trade costs decline. We empirically investigate the existence of this magnification effect by estimating gravity-type equations for worldwide trade to obtain the tariff elasticity of trade per industry. We find that tariff elasticity is higher in industries with a greater degree of global value chain participation. These results are observed for both gross and value-added trade. Furthermore, we find that tariff elasticity is higher in intra-Asian trade, especially in machinery industries.
