Ergodic chaos for non‐expansive economic models**

Ergodic chaos is one of the most important concepts in the theory of nonlinear economics. Due to the lack of appropriate sufficient conditions, its reach has not been fully understood. In this paper a sufficient condition for ergodic chaos that covers non‐expansive dynamical systems is examined. By analyzing an endogenous growth model as an example, we discuss the breadth of models in which ergodic chaos can emerge.     

Does oligopsony power matter in price support policy design? Empirical evidence from the Thai Jasmine rice market

In the oligopsony market, farmers may receive low prices and policy analysis assuming perfect competition can yield serious bias results. In this paper, we estimate oligopsony power between processors and farmers and evaluate the welfare impact of the paddy pledging program (PPP), a generous price support program in the Thai Jasmine rice market, with an imperfect competition model. We develop a model that consists of rice supply equation and derived demand equation. We then simultaneously estimate these equations using system estimation methods to recover oligopsony power parameters. Finally, we use these parameters to assess the welfare impact of the price support program. Using annual panel data running from crop marketing year 2001/2002–2015/2016 and exploiting the institutional feature of the PPP, we find strong evidence of some oligopsony power, a moderate level of oligopsony price distortion, and a negative relationship between price support and oligopsony power. We also find that the PPP is inefficient but effective in income redistribution. Moreover, the program benefits both farmers and consumers. With better policymaking decisions, the PPP can be efficient by setting a suitable support price. Therefore, our results show that in the case of the Thai Jasmine rice market, the generally accepted “wisdom” about agricultural price support policy does not necessarily hold, and price support can be designed to improve the efficiency of the market.     

IFRS Adoption and Stock Prices of Japanese Firms in Governance System Transition

This study examines firms' decision to voluntarily adopt IFRS in a setting where there are changes to the governance system in a traditionally code law country, as well as how the market responds to such decisions. We find the probability of voluntary IFRS adoption to be higher among firms that have a high proportion of foreign shareholders, undertake quality audits, have low levels of leverage, feature a nominating committee, and are included in the new market index. In addition, the stock prices of IFRS adopters tend to increase around the announcement date of IFRS adoption, compared to those of non-adopters. Finally, market reactions are smaller for firms that feature a nominating committee, and are included in the new market index—perhaps because IFRS adoption by these firms is less surprising to market participants, and because IFRS adoption is not expected to add large incremental value to these firms.     

The effect of corruption on the manufacturing sector in India

This article investigates the effects of corruption on the performance of the manufacturing sector at the state level in India. We employ conviction rates of corruption-related cases as an instrument for the extent of corruption, address the underreporting problem, and examine the impact of corruption on the gross value added per worker, total factor productivity, and capital-labor ratio of three-digit manufacturing industries in each state. Our estimation results show that corruption reduces gross value added per worker and total factor productivity. Furthermore, we show that the adverse effects of corruption are more salient in industries with smaller average firm size.     

Event satisfaction,leisure involvement and life satisfaction at a walking event: the mediating role of life domain satisfaction

Given the rising popularity of mass-participant sport, such as walking and running events, research has started to address whether these types of events could promote life satisfaction for participants. Nevertheless, the theoretical link between event participation and life satisfaction has not been fully elaborated. Using bottom-up theory of life satisfaction, this study examined the role of event satisfaction and the three facets of leisure involvement – attraction, centrality and self-expression – in people’s life domain satisfaction and life satisfaction. Participants (N = 236) were recruited from a walking event held in western Japan. The results of the study revealed that event satisfaction had positive, indirect effects on life satisfaction through satisfaction with family life and personal achievement. Attraction in walking also had positive, indirect effects on life satisfaction through satisfaction with family life, personal achievement and social life. In contrast, centrality and self-expression in walking were not associated with satisfaction with any life domains and life satisfaction. Findings from this study highlight the importance of life domain satisfaction in the relationship between event satisfaction, leisure involvement and life satisfaction. These findings also suggest that walking events can promote life satisfaction by providing the enjoyment of walking as physically active leisure.     

Favouritism towards the poor and a discontinuous tax structure

This article aims to theoretically clarify two points. First, even though the government shows favouritism to the poor and wants to exempt low-income taxpayers and to secure the necessary income tax revenue by taxing only high-income taxpayers, the government nevertheless ends up taxing the poor. This is in opposition to favouritism and arises because of the government’s inability to observe the individual taxpayer’s income levels. Second, even without observing each taxpayer’s income level, if favouritism is sufficiently strong, then the government can discontinuously resolve such unintentional taxation.     

The SIML Estimation of Integrated Covariance and Hedging Coefficient Under Round-off Errors,Micro-market Price Adjustments and Random Sampling

For estimating the integrated volatility and covariance by using high frequency data, Kunitomo and Sato (Math Comput Simul 81:1272–1289, 2011; N Am J Econ Finance 26:289–309, 2013) have proposed the separating information maximum likelihood (SIML) method when there are micro-market noises. The SIML estimator has reasonable finite sample properties and asymptotic properties when the sample size is large when the hidden efficient price process follows a Brownian semi-martingale. We shall show that the SIML estimation is useful for estimating the integrated covariance and hedging coefficient when we have round-off errors, micro-market price adjustments and noises, and when the high-frequency data are randomly sampled. The SIML estimation is consistent, asymptotically normal in the stable convergence sense under a set of reasonable assumptions and it has reasonable finite sample properties with these effects.
