Investment allocation: A comparison of the reform experiences of Hungary and Yugoslavia

Both Yugoslavia and Hungary, despite reform efforts, have continued to exhibit investment cycles. An analysis is presented of why the Yugoslav and Hungarian experiences have been so similar despite major institutional differences. An examination of three different capital allocation systems in Yugoslavia identifies both institutional and behavioral factors that undermine reform efforts and reproduce investment cycles not only in Yugoslavia, but also in Hungary and other socialist economies.     

Option pricing under fast-varying and rough stochastic volatility

Recent empirical studies suggest that the volatilities associated with financial time series exhibit short-range correlations. This entails that the volatility process is very rough and its autocorrelation exhibits sharp decay at the origin. Another classic stylistic feature often assumed for the volatility is that it is mean reverting. In this paper it is shown that the price impact of a rapidly mean reverting rough volatility model coincides with that associated with fast mean reverting Markov stochastic volatility models. This reconciles the empirical observation of rough volatility paths with the good fit of the implied volatility surface to models of fast mean reverting Markov volatilities. Moreover, the result conforms with recent numerical results regarding rough stochastic volatility models. It extends the scope of models for which the asymptotic results of fast mean reverting Markov volatilities are valid. The paper concludes with a general discussion of fractional volatility asymptotics and their interrelation. The regimes discussed there include fast and slow volatility factors with strong or small volatility fluctuations and with the limits not commuting in general. The notion of a characteristic term structure exponent is introduced, this exponent governs the implied volatility term structure in the various asymptotic regimes.     

Alternatives to conventional crude oil: When, how quickly, and market driven?

We examine the effect of uncertainty concerning remaining supplies of conventional crude oil and its production path on: the date alternative fuels will be needed, the quantity of alternative fuels needed, and how this uncertainty affects firms' willingness to provide alternatives in a timely fashion. Despite large uncertainties about the quantity of oil that remains and its production path, the start date for replacements is likely to fall within a twenty-two year period that is narrower and earlier than previous estimates. The twenty-two year window represents considerable uncertainty about the date of the peak and this uncertainty creates an asymmetry in the strategy that maximizes the welfare of firms relative to total social welfare, which works against the market's ability to generate a smooth transition from oil to alternative fuels. The timeliness of this transition is critical—the production paths generated here suggest that 10 million barrels per day or more of alternative fuels will be needed within a decade of the peak in production of conventional crude oil.     

Political Knowledge and Attitudes towards Centralisation in Europe

We analyse the impact of political knowledge on the attitudes of European citizens towards the possible distribution of competences between the European Union (EU) and the Member States. Our hypothesis is that citizens who are more informed about the EU will support the centralisation of competences in some policy areas according to the lines predicted by the fiscal federalism literature. We test our hypothesis using micro data from the Eurobarometer survey, taking into account the endogeneity of political knowledge. We find that more knowledgeable citizens are more willing to favour centralisation to the EU in areas where public intervention by individual Member States causes externalities, where economies of scale in the provision of public goods are important and where redistributive and stabilisation functions have to be pursued.     

Capital flows and capital goods

Studying the relation between equity market liberalization and imports of capital goods, we examine one channel through which international financial integration can promote growth. For the period 1980-1997, we find that after controlling for other policies and fundamentals, stock market liberalizations are associated with a significant increase in the share of imports of machinery and equipment. We hypothesize this can be attributed to the consequences of financial integration, which allows access to foreign capital, and provide evidence consistent with this channel. Our results suggest that increased access to international capital allows countries to enjoy the benefits embodied in capital goods.     

SMEs, Social Capital and the Common Good

In this paper we report on empirical research which investigates social capital of Small and Medium Sized Enterprises (SMEs). Bringing an international perspective to the work, we make a comparison between 30 firms located in West London and Munich in the sectors of food manufacturing/production, marketing services and garages. Here we present 6 case studies, which we use to illustrate the early findings from this pilot project. We identify differences in approach to associational membership in Germany and the U.K., with a greater propensity to "belong" to an official group in Germany. We distinguish clear sectoral similarities across the countries, and indications that certain personality types will seek out engagement and find time beyond busy work life schedules, often merging work/home/leisure life and friends. Some of our cases illustrate that formal institutions, networks and mutual relationships can develop social capital for the SME, although we should take care not to assume a universal win-win situation for those who are engaged and contribute to the common good. Some of the obstacles to co-operation and civic engagement are outlined.     

Ethics,CSR, and Sustainability Education in the <Emphasis Type="Italic">Financial Times</Emphasis> Top 50 Global Business Schools: Baseline Data and Future Research Directions

This paper investigates how deans and directors at the top 50 global MBA programs (as rated by the Financial Times in their 2006 Global MBA rankings) respond to questions about the inclusion and coverage of the topics of ethics, corporate social responsibility, and sustainability at their respective institutions. This work purposely investigates each of the three topics separately. Our findings reveal that: (1) a majority of the schools require that one or more of these topics be covered in their MBA curriculum and one-third of the schools require coverage of all three topics as part of the MBA curriculum, (2) there is a trend toward the inclusion of sustainability-related courses, (3) there is a higher percentage of student interest in these topics (as measured by the presence of a Net Impact club) in the top 10 schools, and (4) several schools are teaching these topics using experiential learning and immersion techniques. We note a fivefold increase in the number of stand-alone ethics courses since a 1988 investigation on ethics, and we include other findings about institutional support of centers or special programs; as well as a discussion of integration, teaching techniques, and notable practices in relation to all three topics.
