It has been argued that the threat of regulatory intervention affects firm behavior. We investigate the pricing decision of
the dominant firm under regulatory threat, considering the probability of intervention as a function of the price. Our focus
is on the case where the potential divestiture of the firm serves as a threat of regulatory intervention. It is shown that
under certain conditions associated with the marginal expected penalty, the mere threat of divesting a certain portion of
the firm’s manufacturing plants leads to a lower price than the actual divestiture of that same portion. Numerical examples
illustrate that with relatively small-scale divestiture, the firm’s price under the threat may be lower than that under the
actual divestiture, within a relatively broad range of regulator’s attitudes toward intervention. 相似文献

Less developed countries have received substantial foreign aid for transport infrastructure, making its quantitative assessment important. To investigate the effect of aid for road infrastructure on the location of foreign and domestic firms, this study employs the first comprehensive census on all business establishments in Cambodia for 2011 and measures the geographical distribution of aid disbursements in roads. Estimating a negative binomial model, we find that aid disbursements in roads have little influence on the entry of foreign and domestic firms across communes. Compared with the aid effect, the location of firms is more strongly influenced by other determinants such as population size, electricity access, and labor supply. 相似文献

By extending the work of Mourmouras and Lee (1999), we show that the growth-maximizing income tax rate maximizes also the utilities of not only all current generations but also all future generations. This result means that the statement that the growth-maximizing income tax rate is equivalent to the welfare maximizing one holds true in a stronger sense than Barro (1990) and Mourmouras and Lee (1999) have pointed out. 相似文献

This paper investigates how imitation activities affect the technology gap between developing and developed countries using
a North-South model in which the variety of goods is expanding over time. If imitation productivity is high enough, nonrivalrous
ideas and inexpensive labor enables developing countries to reduce their technological backwardness by imitating products
even if their initial level of technology is far behind the technology in developed countries. We also show that the rise
of imitation productivity may benefit both developing and developed countries if they prefer a sufficient variety of goods. 相似文献

We will show that in the case where there are two individuals and three alternatives (or under the assumption of the free-triple property), and individual preferences are weak orders (which may include indifference relations), the Arrow impossibility theorem [Arrow, K.J., 1963. Social Choice and Individual Values, second ed. Yale University Press] that there exists no binary social choice rule which satisfies the conditions of transitivity, Pareto principle, independence of irrelevant alternatives, and non-existence of dictator is equivalent to the Brouwer fixed point theorem on a 2-dimensional ball (circle). Our study is an application of ideas by Chichilnisky [Chichilnisky, G., 1979. On fixed points and social choice paradoxes. Economics Letters 3, 347–351] to a discrete social choice problem, and also it is in line with the work by Baryshnikov [Baryshnikov, Y., 1993. Unifying impossibility theorems: a topological approach. Advances in Applied Mathematics 14, 404–415]. 相似文献

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
