Cooperative choice and its framing effect under threshold uncertainty in a provision point mechanism

This paper explores how threshold uncertainty affects cooperative behaviors in the provision of public goods and the prevention of public bads. The following facts motivate our study. First, environmental (resource) problems are either framed as public bads prevention or public goods provision. Second, the occurrence of these problems is characterized by thresholds that are interchangeably represented as “nonconvexity,” “bifurcation,” “bi-stability,” or “catastrophes.” Third, the threshold location is mostly unknown. We employ a provision point mechanism with threshold uncertainty and analyze the responses of cooperative behaviors to uncertainty and to the framing for each type of social preferences categorized by a value orientation test. We find that aggregate framing effects are negligible, although the response to the frame is the opposite depending on the type of social preferences. “Cooperative” subjects become more cooperative in negative frames than in positive frames, whereas “individualistic” subjects are less cooperative in negative frames than in positive ones. This finding implies that the insignificance of aggregate framing effects arises from behavioral asymmetry. We also find that the percentage of cooperative choices non-monotonically varies with the degree of threshold uncertainty, irrespective of framing and value orientation. Specifically, the degree of cooperation is highest at intermediate levels of threshold uncertainty and decreases as the uncertainty becomes sufficiently large.     

Financial Sector Risk and the Stock Returns: Evidence from Tokyo Stock Exchange Firms

We investigate whether the activity of financial firms creates value and/or risk to the economy within the asset pricing framework. We use stock return data from nonfinancial firms listed in the first section of the Tokyo Stock Exchange. The value-weighted index that is solely composed of nonfinancial firms is augmented with the index of the firms from the financial sector, and we estimate multivariate asset pricing model with these two indices. We note that our procedure can simultaneously take into account the cross-holding phenomena among Japanese firms, especially between the financial sector and the nonfinancial sector. Our augmented index model performs well both with cross-sectional Fama and MacBeth regression test and GMM test. Our two index model with additional Fama and French's HML factor can capture cross-sectional variations of the returns of sample portfolios better than the original Fama and French model can, when measured by Hansen and Jagannathan distance measure. We find that this additional new sector variable can be a substitute for Fama and French's size factor, but not related to the bond index return. This variable has similar factor characteristic as money supply growth or the term structure, but the latter variables contain more information than the former. Morever, our financial sector model helps explain the return and risk structure of Japanese firms during the so-called bubble period.     

A note on “raising the mandatory retirement age and its effect on long‐run income and Pay As You Go (PAYG) pensions”

Fanti (2014, Metroeconomica, 65, 619–645) showed that raising the mandatory retirement age always reduces capital accumulation and may lower per young income and pension benefit, under the assumption that old labor and young labor are perfect substitutes (or equivalently, the elasticity of substitution is infinite). We reexamine his analysis by assuming that the two labors are imperfect substitutes (the elasticity of substitution is finite), and prove that his results no longer hold when the elasticity of substitution is not sufficiently high.     

Robust pricing with refunds

Before purchase, a buyer of an experience good learns about the product's fit using various information sources, including some of which the seller may be unaware of. The buyer, however, can conclusively learn the fit only after purchasing and trying out the product. We show that the seller can use a simple mechanism to take best advantage of the buyer's post-purchase learning to maximize his guaranteed-profit. We show that this mechanism combines a generous refund, which performs well when the buyer is relatively informed, with non-refundable random discounts, which work well when the buyer is relatively uninformed.     

Employment tenure,job expectancy,and earnings profile in Japan

The purpose of this study is to examine the relationships between employment tenure and earnings profile in Japan. Since the Japanese labour market has recently experienced substantial changes, it is natural for the Japanese employment and compensation system to be influenced by such changes. In this study, the changes that have happened to the Japanese employment and compensation system in recent years have been considered empirically by focusing on the relationships between employment tenure and earnings profiles. To do this, a forward-looking variable called ‘expected job tenure (or job expectancy)’ is introduced and the effects of it on earnings profile.     

The theory of effective protection in general equilibrium with interindustrial flows

The purpose of the present note is to demonstrate that the sufficiency condition of Bruno (1973) and Sendo (1974) on tariff changes is valid as an ERP index in the sense defined by Bhagwati and Srinivasan (1973), within the framework of the Bhagwati-Srinivasan general equilibrium model with two industries, even if we admit interindustrial flows.     

Dissemination of Accruals Information,Role of Semi‐Annual Reporting,and Analysts' Earnings Forecasts: Evidence from Japan

Our study investigates the effects of dissemination of accounting accruals information on stock prices using Japanese annual reports as our sample. We conduct month‐by‐month detailed analyses of price adjustment behavior with a particular focus on revisions of analysts' earnings forecasts and changes in trading volume around the period of upcoming semi‐annual reports. We find that analysts' forecasts are often revised around this time, and analysts use this as auxiliary information. In addition, an accompanying re‐adjustment of abnormal returns and an increase in trading volume are observed. Our findings demonstrate that informational uncertainty initially triggered by the announcement of annual reports decreases as semi‐annual reports are disclosed and analysts change their earnings forecasts, and confirms the importance of semi‐annual reporting.

Does the diversity of human capital increase GDP? A comparison of education systems

This paper examines how different education systems affect GDP by influencing the diversity of human capital. We construct an overlapping generation model in which agents are heterogeneous in income and innate ability, and the final goods are produced with differentiated intermediate goods. It is shown that under a realistic condition, the diversity of human capital induced by income inequality always lowers the GDP of the next period, while the diversity of human capital induced by heterogeneous ability can increase GDP, if the produced intermediate goods are sufficiently substitutable and firms have a large span of control. Hence, as public education equalizes education resources across households, it mitigates the negative effect of income inequality on GDP, while the effects of ability tracking crucially depend on the production structure of the economy.
