We developed a new scheme for computing “Greeks” of derivatives by an asymptotic expansion approach. In particular, we derived analytical approximation formulae for Deltas and Vegas of plain vanilla and average European call options under general Markovian processes of underlying asset prices. Moreover, we introduced a new variance reduction method of Monte Carlo simulations based on the asymptotic expansion scheme. Finally, several numerical examples under CEV processes confirmed the validity of our method. 相似文献

We develop a two‐country dynamic trade model with public infrastructure having an “unpaid‐factor”‐type positive externality on private sectors’ productivity. With welfare‐maximizing national governments making infrastructure investment, we show that a country with a smaller labor endowment, a lower depreciation rate of infrastructure, and/or a lower time preference rate will become an exporter of a good that is more dependent on infrastructure and will gain from trade, whereas its trading partner may lose from trade. We consider both the nonstrategic governments case and the case of strategic governments that recognize the effect on the terms of trade. 相似文献

We develop a simple model of policy coordination on domestic standards and examine whether domestic standards policy can lead to regional and multilateral harmonization of standards under the principle of national treatment. This paper focuses on mandatory product and process standards affecting the characteristics of a final good that control negative consumption externalities (e.g., vehicle emissions control and safety standards, restrictions on the use of pesticides for agricultural goods, and safety standards for electrical products). Only the products that meet a country's national standards are allowed to circulate in that country's market. Raising standards reduces negative externalities caused by consumption of a traded good but increases firms’ costs. We use the core as the solution concept. A standards regime is considered to be in the core if it is not blocked by any coalition within countries. The main finding is that a multilateral agreement on standards that maximizes world welfare is only in the core if externalities are local or slightly transboundary. Otherwise, only a regional agreement on standards is in the core. As extensions, we consider many and asymmetric number of firms, asymmetry in market size, fixed costs for different standards, and a multilateral agreement on different standards. 相似文献

This study reexamines McMillan's (International Economic Review 19 (1978), 665–78) analysis of a dynamic small open economy with a public intermediate good. Concerning the trade patterns of the open economy, we find results that were overlooked in McMillan's analysis. Among others, if labor endowment is of intermediate size, there are two saddle‐point steady states, and the initial stock of the public good determines the long‐run trade pattern. We also add a gains‐from‐trade analysis to McMillan's model and demonstrate that if the economy has a comparative advantage in a good with productivity less sensitive to the public intermediate good, the economy may lose from trade at the steady state. 相似文献

This paper tests if a firm's pension funding ratio (pension assets/PBO) reveals the management's private information about the firm's operation when the firm can exercise discretion in pension funding. The lax enforcement of pension funding rules and the prevalence of management forecasts make Japanese firms an ideal testing ground. We show that, among firms with large business uncertainty, large accruals, or high effective tax rates, the pension funding ratio predicts the firm's management forecast errors significantly beyond conventional control variable and the effects of pension accounting management. However, the stock market does not appear to incorporate this information immediately. 相似文献

Teams in Japan's two professional baseball leagues began to add foreign players in the early 1950s, with the average number per team reaching 5.79 in 2004. This was primarily because foreign hitters outperformed Japanese hitters. Hazard analysis shows that a poorly performing team was more likely to hire its first Caucasian and African American players earlier than a successful team. Econometric analysis of team use of foreign players over 45 seasons (1960–2004) shows that losing Central League teams used foreign players more often in following season(s), whereas past success of Pacific League teams did not affect their use of foreign players. 相似文献

This study develops a general pricing method for multiasset cross‐currency options, whose underlying asset consists of multiple different assets, and the evaluation currency is different from the ones used in the most liquid market of each asset; the examples include cross‐currency options, cross‐currency basket options, and cross‐currency average options. Moreover, in practice, fast calibration is necessary in the option markets relevant for the underlying assets and the currency, which is also achieved in this study. © 2012 Wiley Periodicals, Inc.

We study infinitely repeated symmetric 2×2 games played by bounded rational agents who follow a simple rule of thumb: each agent continues to play the same action if the current payoff exceeds the average of the past payoffs, and switches to the other action with a positive probability otherwise. By applying the stochastic approximation technique, we characterize the asymptotic outcomes for all 2×2 games. In the prisoners’ dilemma game, for example, the players cooperate in the limit if and only if the gain from defecting against cooperation is “modest.” 相似文献

This paper examines an impact of Bank of Japan (BOJ)’s outright purchase on the Japanese government bond (JGB) yield curve. Particularly, we develop a simple state space model, which incorporates new factors regarding the BOJ’s announcement for its outright purchase and the current market outstanding with standard level and spread factors. Based on the model with a filtering method, we also implement an empirical analysis with time series of the BOJ’s announcement records during 2014/10/22–2017/8/3 in the quantitative–qualitative easing period to estimate the sensitivities of interest rates against the changes in the market expectation for the net supply with each sector of JGB. We expect the current work provides a basis for considering quantitative effects on the term structure by BOJ’s policy changes such as termination or significant reduction of the BOJ’s outright purchase. For instance, our scenario analysis shows substantial increase in the 30 year yield with widening of 20–30 year spread. 相似文献
