Unemployment in Japan nearly tripled during the 1990s. Underlying this upsurge lie an increase in the probability of workers to lose their jobs and a decrease in the probability that the unemployed find jobs. This paper analyzes the sources responsible for these labor market changes in Japan in the decade of the 1990s. We build, calibrate, and simulate a neo-classical growth model with search frictions in the labor market. Using actual TFP data, the model is able to reproduce the path of unemployment and the job flows, as well as that of output. We find it to be the decrease in productivity, coupled with the reduction in hours worked, which curtails the profits of firms, inducing a drop in employment and an increase in unemployment. 相似文献

Agricultural development is indispensable for poverty reduction and food security in sub‐Saharan Africa (SSA). This study investigates the impact of rice production training in a modified version of the System of Rice Intensification (SRI) on the performance of small‐scale rice farmers in a rainfed area of Tanzania. Utilizing the plot level variation, we employ propensity score matching (PSM) to assess the impact of training on technology adoption, productivity, and profitability. We also estimate a difference‐in‐differences model with plot fixed effects using recall panel data covering the periods before and after training. We found that trainees achieved an average paddy yield of 4.7 tons per hectare and rice profit of 191.5 USD per hectare on the plots where new technologies were adopted, which is higher by about 1.3–1.8 tons and 119–137 USD per hectare than on the other plots. Our study suggests the high potential of transforming favorable rainfed rice growing areas in SSA so as to achieve a rice Green Revolution through training in modern input use and improved agronomic practices. 相似文献

Constructing an endogenously growing overlapping generations model with public investment, we examine the welfare effects
of a fiscal reconstruction policy. In this paper we define a fiscal reconstruction policy as a policy where the government
reduces its spending level without changing the tax revenue and allocates the surplus of the revenue to redeem public debt.
We show that if government spending is not productive it is possible that a fiscal reconstruction policy improves the utilities
of both the current and future generations, while if government spending is productive it can harm the utilities of both generations.

In this paper gender wage decompositions are performed for three very different countries, that is, Japan, Russia and the USA for the years of 1993 and 2000, using the ISSP data set. From the research of this paper, it is shown that the gender wage differential in Japan has narrowed between 1993 and 2000, and the results reveal price and characteristics effects for this country that differ markedly from those observed elsewhere, with female disadvantage being particularly marked. Also, this paper finds that gender wage differentials in Russia and the USA have increased during the years considered here. 相似文献

Aims: Heavy menstrual bleeding (HMB) is a highly prevalent condition, characterized by excessive menstrual blood loss and cramping, that interferes with activities of daily life. The aim of this study was to investigate treatment patterns in HMB in Japan, and to assess healthcare resource utilization and costs among women newly-diagnosed with the condition.Materials and methods: This study retrospectively analyzed health insurance data available in the Japan Medical Data Center (JMDC) database on women aged 18–49 years who were newly-diagnosed with primary or secondary HMB. Treatment patterns were analyzed, and healthcare utilization and costs were evaluated and compared to matched controls.Results: The study included a total of 635 patients, 210 with primary HMB and 425 with secondary HMB. In the primary HMB cohort, 60.0% of patients received one or more pharmacological or surgical treatments, compared with 76.2% in the secondary HMB cohort. The most commonly prescribed medications in all patients were hemostatic agents (28.7%), traditional Chinese medicine (TCM) (12.1%), and low-dose estrogen progestins (LEPs) (10.1%). After adjustment for patient baseline characteristics, healthcare costs were 1.93-times higher in primary HMB cases (p?<?.0001) and 4.44-times higher in secondary HMB cases (p?<?.0001) vs healthy controls. Outpatient care was the main cost driver.Limitations: The main limitations of this study are related to its retrospective nature, and the fact that only reimbursed medications were captured in the source database.Conclusions: A substantial proportion of HMB patients did not receive the recommended treatments. Healthcare costs were considerably increased in the presence of an HMB diagnosis. 相似文献

Using a natural field experiment, we quantify the impact of one‐dimensional performance‐based incentives on incentivized (quantity) and nonincentivized (quality) dimensions of output for factory workers with a flat‐rate or a piece‐rate base salary. In particular, we observe output quality by hiring quality inspectors unbeknownst to the workers. We find that workers trade off quality for quantity, but the effect is statistically significant only for workers under a flat‐rate base salary. This variation in treatment effects is consistent with a simple theoretical model that predicts that when agents are already incented at the margin, the quantity–quality trade‐off resulting from performance pay is less prominent. 相似文献

Abstract This paper re‐examines how differences in systems for financing education influence GDP by highlighting a neglected function of education policy: it affects the magnitude of gains from job assignment. When more productive jobs demand more skill, privately financed education can increase productivity gains from matching between jobs and skill by increasing the availability of highly educated people. This differs from the standard argument that publicly financed education increases the total amount of human capital by equalizing educational opportunities. It is shown that if job opportunities have large variations in productivity, education policy may face a serious efficiency–equity trade‐off. 相似文献

The purpose of this paper is to demonstrate the powerful and flexible applicability of the Gram–Charlier expansion to pricing of a wide variety of interest rate related products involving interest rate risk and credit risk. In this paper, we develop easily implemented approximations of the prices of several derivatives; swaptions, CMS, CMS options, and vulnerable options. Associated with the default risk, a survival contingent forward measure is constructed. 相似文献

This paper examines the effect of individual transferable quota regimes on technology choice, such as choice of vessel size, by using the laboratory experiment method. We find that even if vessel sizes change over time, the quota price can converge to the fundamental value conditioned on the vessels chosen. We also find that subjects choose their vessel type to maximise their profits based on the quota trading prices in the previous period. This result implies that the efficiency of quota markets in the beginning period is important because any inefficiency in quota markets may affect vessel sizes in ensuing periods. Moreover, we find that the initial allocations may significantly influence vessel sizes through two channels: first, a higher initial allocation to a subject increases the likelihood that the subject invests in a large‐sized vessel; second, the quota price may be higher and more unstable under unequal allocation than under equal allocation; thus, whether the allocation is equal influences subjects' choice of vessel type. 相似文献
