Diversification of infrastructure projects for emergent and unknown non‐systematic risks

Allocating resources to competing large‐scale infrastructure projects involves multiple objectives. Traditional decision‐aiding methodologies focus on the trade‐offs among performance and resource objectives. Existing methodologies may fail to account for unknown and emergent risks that are typical of large‐scale infrastructure investment allocation problems. In modern portfolio theory, it is well known that a diversified portfolio can be very effective to reduce non‐systematic risks. The approach of diversification is equally important in choosing robust portfolios of infrastructure projects that may be subject to emergent and unknown risks. In this paper, we demonstrate a methodology to analyze and compare the diversification of portfolios of large‐scale infrastructure projects. We classify and explore several metrics of diversification and integrate them with risk and other performance objectives in a multiobjective approach. We test the new metrics and the methodology in a case study of hundreds of millions of dollars of infrastructure investments. The results suggest that the solutions that consider diversification are more robust to emergent risks, thus, identifying an opportunity to incorporate diversification‐based optimization methodologies to support a variety of problems involving large‐scale infrastructure investments.     

Achieving smooth asymptotics for the prices of European options in binomial trees

A new binomial approximation to the Black–Scholes model is introduced. It is shown that, for digital options and vanilla European call and put options, a complete asymptotic expansion of the error in powers of n ^?1 exists. This is the first binomial tree for which an asymptotic expansion has been shown to exist.     

Women can change the future

This article examines the role of Asian women—particularly the Asian village woman who holds a key to revitalizing the economic system. A change in the method of cloth production to a system of women producing cloth in thousands of villages and city slums with spinning-wheels would provide the basis of social revolution and economic change. Other future scenarios for Asian women are outlined and the rudiments of an Asian feminist perspective are presented.     

India's economic reforms: Progress,problems, prospects

Abstract

This paper is a review of India's progress in the 50 years of Independence, which is regarded as a mixture of the impressive and the disappointing. The country has managed to protect national unity, preserve democracy and dilute traditional social hierarchies. There has been economic growth and a reduction in the proportion of people falling below a standard poverty line. But the main requirement now is a sustained increase in the growth rate of national income that also increases the demand for labour. The relative failures of past decades are considered, and ways in which the reform programme begun in July 1991 could be strengthened are suggested.     

Corporate Ecological Responsiveness: Antecedent Effects of Institutional Pressure and Top Management Commitment and Their Impact on Organizational Performance

Institutional theory argues that conformity to institutional pressure enhances the survival probability of organizations. Two key limitations of institutional theory have been proposed in recent literature: one, that it ignores the role of top management, and two, that it focuses only on survival as a benefit to the exclusion of more strategic benefits such as growth and profitability. In this research, we build a conceptual model that addresses both of these limitations in the context of institutional pressure on organizations to behave more responsibly vis‐à‐vis the natural environment. Results from a survey of 199 manufacturing firms show that the relationship between institutional pressure and corporate responsiveness to the pressure (i.e. corporate environmental responsiveness) is enhanced when top management commitment to the environment is high. Moreover, results show that organizational conformity to institutional pressure enhances the strategic benefits that organizations receive.

INTRODUCTION / THE STATUS OF WOMEN ECONOMISTS IN US UNIVERSITIES AND THE WORLD / THE STATUS OF WOMEN ECONOMISTS IN UK UNIVERSITIES / THE STATUS OF WOMEN ECONOMISTS IN CANADIAN UNIVERSITIES / THE STATUS OF WOMEN ECONOMISTS IN CHINA'S UNIVERSITIES

Abstract

These Explorations, by eight authors from Canada, China, the US, and the UK, examine the current status of women in economics (with an eye mainly toward their status in the academic branch of the profession). The four sections of the work analyze results of surveys that show the distribution of academic positions among women economists in universities in Canada, the UK, the US, and China. The work also provides a short history of the development of committees and groups interested in furthering the status of women in the economics profession and suggests ways to improve the efforts of such groups and the status of women economists.     

FAST MONTE CARLO GREEKS FOR FINANCIAL PRODUCTS WITH DISCONTINUOUS PAY‐OFFS

We introduce a new class of numerical schemes for discretizing processes driven by Brownian motions. These allow the rapid computation of sensitivities of discontinuous integrals using pathwise methods even when the underlying densities postdiscretization are singular. The two new methods presented in this paper allow Greeks for financial products with trigger features to be computed in the LIBOR market model with similar speed to that obtained by using the adjoint method for continuous pay‐offs. The methods are generic with the main constraint being that the discontinuities at each step must be determined by a one‐dimensional function: the proxy constraint. They are also generic with the sole interaction between the integrand and the scheme being the specification of this constraint.     

Factors influencing the adjustment of women on global assignments

This study tests a four-factor model proposed by Caligiuri and Cascio (in press) for predicting the cross-cultural adjustment of female expatriates. The four factors tested in this paper were family support, personality characteristics, organizational support and host nationals' attitudes towards female expatriates. Structured phone interviews with thirty-eight American female expatriates from US-based companies were conducted. The responses were content analysed and regression was conducted. The results suggest company and family support are significantly related to cross-cultural adjustment. Thus, suggestions are given for future research on female expatriates using the theoretical model of social support. Practical recommendations for how to maximize the likelihood of success for women on global assignments are also given.     

Does Public Country-by-Country Reporting Deter Tax Avoidance and Income Shifting? Evidence from the European Banking Industry*

In this study, we examine the effect of increased tax transparency on the tax planning behavior of European banks. In 2014, the European Union introduced public country-by-country reporting requirements to the banking industry. Treating this new requirement as an exogenous shock, we find limited evidence consistent with a decline in income shifting by the banks' financial affiliates in the post-adoption period (starting from 2015). We do not, however, find robust evidence of a significant change in the consolidated book effective tax rates among the affected banks. Our findings suggest that increased transparency from public country-by-country reporting can deter tax-motivated income shifting but that it did not appear to materially influence the banks' overall tax avoidance. Our findings have policy implications for the ongoing debate between the European Parliament, the Organisation for Economic Co-operation and Development, and accounting standard-setting bodies on whether to require multinationals to publish country-by-country reports.
