Quantitative easing and Japanese bank equity values

One of the primary motivations offered by the Bank of Japan (BOJ) for its quantitative easing program—whereby it maintained a current account balance target in excess of required reserves, effectively pegging short-term interest rates at zero—was to maintain credit extension by the troubled Japanese financial sector. We conduct an event study concerning the anticipated impact of quantitative easing on the Japanese banking sector by examining the impact of the introduction and expansion of the policy on Japanese bank equity values. We find that excess returns of Japanese banks were greater when increases in the BOJ current account balance target were accompanied by “non-standard” expansionary policies, such as raising the ceiling on BOJ purchases of long-term Japanese government bonds. We also provide cross-sectional evidence that suggests that the market perceived that the quantitative easing program would disproportionately benefit financially weaker Japanese banks. J.

An Advertising Strategy Using Consumption Externality and Forgetting in the Case of Japanese Electronic Books

We construct a two-period model in which a consumer recognizes the existence of goods after advertised by firms, and total sales of the first period affect the utility of each consumer’s purchase in the second period, indicating a consumption externality. Some consumers see advertisements in the first period and remember the product, whereas some forget the product in the second period. We show that the advertising volume changes given the differences in the forgetting rate. In particular, we apply our method to the data on Japan’s electronic books obtained through a conjoint analysis survey to clarify that a better strategy is to sell a product to a small number of people at a low price or to lower the price to a certain level during the early period, and then to sell the product to a specific consumer segment at a higher price after reflecting the externality.     

Do the Rich Save More in Japan? Evidence Based on two Micro Data Sets for the 2000s

Using two household surveys, this paper investigates whether the saving rates of richer households are higher than those of poorer households in Japan. We construct a number of proxies for lifetime wealth, including those original to this study, and find marginally positive correlations between saving rates and lifetime wealth for working age households. We further find that the relationship between saving rates and lifetime wealth differs depending on the life stage of individual households. Older households with higher lifetime wealth appear to be dissaving to some extent, which is more or less consistent with the lifecycle model of consumption.     

Team Incentives and Reference‐Dependent Preferences

We investigate a multi‐agent moral‐hazard model where agents have expectation‐based reference‐dependent preferences à la K?szegi and Rabin (2006, 2007). We show that even when each agent's probability of success in a project is independent, a principal may employ team incentives. Because the agents are loss averse, they have first‐order risk aversion to wage uncertainty. This causes the agents to work harder when their own failure is stochastically compensated through other agents' performance. In the optimal contract, agents with high performance are always rewarded, whereas agents with low performance are rewarded if and only if other agents' performance is high.     

Measurement of redistributive effect of tax rates from a longitudinal perspective: an application of the fixed taxable income approach

The primary objective of this article is to explore how the redistributive effects of tax rate change when using the fixed taxable income approach – where tax rates for each year in a period are applied to taxable income for a base year to calculate rate effects – instead of using an existing procedure to compute the rate effects. Standard rate effects are found to differ considerably from those calculated using the fixed taxable income approach in terms of both level and longitudinal trend.     

Thirty-five years of journal of econometrics

INTENSIFICATION OF RAINFED LOWLAND RICE PRODUCTION IN WEST AFRICA: PRESENT STATUS AND POTENTIAL GREEN REVOLUTION

The objective of the current paper is to explore the factors influencing the expansion and intensification of rice production in rainfed lowland sites. The village/lowland‐level data show the following: (1) the expansion of lowland rice cultivation has been driven by population pressure and accessibility to the market; and (2) the adoption of water control technologies is enhanced by the existence of immigrants and accessibility to the market. Rice cultivator data show that investment in water supply canals is influenced by land tenure security and that the canals enhance yield. This suggests that investment in water control technologies in rainfed lowland is necessary to realize a rice Green Revolution. Considering the fairly high average yield already achieved with water control technologies and the vast area of lowlands without water control technologies in rural area, there is a high potential of a rice Green Revolution in rainfed lowland in West Africa.     

Shared renewable resources and gains from trade under technology standards

Using a two‐country, two‐good model of international trade, we examine gains from trade and strategic interaction in resource management among countries that share renewable resources such as fishery stocks. Two goods are a resource good, which is the harvest of the shared stock, and some other good that may be thought of as manufactures. The productivity of the resource good depends on harvesting technology and the stock level. This paper focuses on technology standards (e.g., restrictions on fishing gears, vessels, areas, and time) over other methods for resource management because they are most commonly implemented in fisheries. Technology standards are modeled as a restriction on the harvesting technology; that is, under strict technology standards, firms exploit resources as if they are using inferior harvesting technology. We show that an opening up of trade may reduce the shared stock and cause steady‐state utility to decrease in a resource‐good importing country and increase in a resource‐good exporting country. Strikingly, when the shared stock is in jeopardy (a high demand for the harvest), steady‐state harvest is maximized after an opening up of trade by what we call multilateral resource management in this paper and both countries gain from trade.
