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. 相似文献

In the paper, an analysis is made of the intolinkages between systems, key components and components' generic technologies in building technological competencies. The sample consists of a set of seven Japanese and four European firm in the industrial, consumer electronics and materials sectors, engaged in the field of optoelectronics. Three tyes of information-—scientific publications, US patenting and interview data—are used. The findings demonstrate the existence ofsuch interlinkages.It was possible to confirm empirically the concept of generic technologies which are the basic underbing technologies forming thefoundation of a range of key components. The generic technologia are important for all firms, irrespectives of their final product markets. Building capabilities at the upstream and over a long period allows firms to develop more high value-added systems and products. It also provides forms with the opportunity to branch into new areas. 相似文献

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. 相似文献

This paper considers a pure exchange stochastic overlapping generations model in which, on each date, an economy faces an aggregate endowment shock. On each date, a young agent and an old agent simultaneously decide how much of their respective endowments to transfer to the other agent; however, a young agent cannot make promises about how much he or she will give when old. In this sense, an economy faces a limited commitment constraint. This paper characterizes an efficient intergenerational risk sharing allocation that satisfies a limited commitment constraint, and also studies the role of money and history in a stochastic overlapping generations economy. 相似文献

Recently, smart glasses have been applied in the field of maintenance, with which a worker goes well during work by contacting a support operator from a remote location. The worker, however, cannot go well if the support operator is not there. To solve the issues, this paper discusses how a work system should be developed by integrating smart glasses with a question-answering module. We design the work knowledge acquired from skilled people and manuals as a workflow for when type of question, rule base for how, goal tree for why, domain ontologies, and its RDF data for what. Workers can receive answers from the question-answering module incorporated with multiple knowledge bases for four types of question. The authors conducted a demonstration experiment and found that workers could perform the work more autonomously by importing the system. 相似文献

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. 相似文献

This study investigates the changes in the riskiness of foreign firms listed in the U.S. following the passage of the Sarbanes-Oxley Act (SOX), legislation aimed at calming investor fears. While capital market measures of risk increase on average over a shorter-term period, total and unsystematic risk measures decrease on average over a longer-term period. Finding longer-term decreases in these risk measures is consistent with reductions in investor uncertainty. Further cross-sectional analyses show that foreign firms considered to be less uncertain at the time of SOX passage received the greatest risk reductions in the post-SOX period. Thus, it appears that the less uncertain foreign firms especially benefited from the heightened awareness and investor focus that occurred in conjunction with the passage of SOX. 相似文献

This paper provides an analysis of firms’ optimal prices when individual utility exhibits both material and other consumer effects. We construct a model and conduct an analysis in the following four steps: (1) By using a conjoint analysis of data, we set up a hierarchical Bayesian model and estimate its parameters, which are composed of individual utility functions. (2) We calculate the number of sales in each time period and derive the total sales throughout the given period. (3) We estimate the demand functions in the presence and absence of consumption externalities. (4) Finally, we calculate the profit functions and derive the optimal prices taking into account various product attributes. By applying our analysis to the book market of Japan, we find that the optimal price is lower when an externality is present than when absent. The intuition behind this result is that pricing low and selling a large number of books from an early stage increases the externality effect, yielding a higher profit for firms. 相似文献

Recent empirical research finds that the degree of nominal rigidities varies over monetary policy regimes. This implies that monetary policy analysis with exogenously given nominal rigidities is subject to the Lucas critique. We allow firms to choose the probability of price adjustment in a Calvo-style sticky price model, and analyze how this probability changes according to an inflation coefficient of the Taylor rule. The model shows that a more aggressive monetary policy response to inflation makes firms less likely to reset prices and gives the resulting New Keynesian Phillips curve a flatter slope and a smaller disturbance, as observed during the Volcker-Greenspan era. Also, such a policy response can stabilize both inflation and the output gap by exploiting the feedback effects of this policy response on firms’ price-setting. These results offer theoretical support for the good policy hypothesis about the Great Moderation. 相似文献
