Overlapping Generations or Infinitely-Lived Agents: Intergenerational Altruism and the Economics of Global Warming

Do we need an overlapping generations model for the economics of global warming? To answer this question, an infinitely-lived agent (ILA) approach and an overlapping generations (OLG) model are contrasted. ILA and OLG can be viewed as polar representations of intergenerational altruism. With ILA an immortal agent acts through his investment/savings decisions as trustee on the behalf of the future generations. With OLG, agents need not behave altruistic. They simply save during working years and dissave completely during retirement. Nevertheless, ILA and OLG must not differ in their implication for greenhouse policy. Greenhouse gas abatement is a straightforward alternative to physical capital formation and, even without altruism, each age cohort has an incentive to provide current abatement in order to reduce future damages attributable to climate change. Indeed, under reasonable assumptions and parameter values, our simulations reveal such an invariance result. Provided carbon taxes are the only policy tool and tax revenues are recycled through socially mandated rules, projections of economic growth, climate change and energy consumption are only insignificantly affected by the choice of approach.     

The Lévy LIBOR model

Models driven by Lévy processes are attractive because of their greater flexibility compared to classical diffusion models. First we derive the dynamics of the LIBOR rate process in a semimartingale as well as a Lévy Heath-Jarrow-Morton setting. Then we introduce a Lévy LIBOR market model. In order to guarantee positive rates, the LIBOR rate process is constructed as an ordinary exponential. Via backward induction we get that the rates are martingales under the corresponding forward measures. An explicit formula to price caps and floors which uses bilateral Laplace transforms is derived.     

Reserve Requirements,Liquidity Risk,and Bank Lending Behavior

Although reserve requirements (RR) have been used in emerging markets to smooth credit cycles, the transmission mechanism remains blurry. Using bank‐level data, we unveil the interaction of RR with bank lending. We identify a new channel that works through a decline in banks’ liquid assets and loan supply due to an increase in RR. “Quantitative tightening” through RR raises the short‐term funding needs of the banking system, which is met by collateralized central bank lending, thus depleting banks’ unencumbered liquid assets. Our results suggest that such a shift in bank liquidity is associated with a significant change in lending.     

Persistent mispricing in a recently opened emerging index futures market: Arbitrageurs invited

The purpose of this study is to analyze the persistent, typically negative, mispricing in the new stock index futures market in Turkey, which has amounted to 5–8%, several multiples of transaction costs. The observations suggest that it is the outcome of a combination of practical difficulties of shorting in the spot stock market, behavioral effects, and insufficient arbitrage. The magnitude of the mispricing and the absence of arbitrage make behavioral effects more visible and provide a unique opportunity to examine extant behavioral hypotheses. Results confirm effects such as disposition and/or conservatism with the mispricing negatively related to past returns, but unrelated to future returns. Finally, an orderly weakening of the negative relation to past returns and behavioral effects is observed, suggesting that such effects will diminish as the market matures. © 2009 Wiley Periodicals, Inc.

Portfolio optimization based on GARCH-EVT-Copula forecasting models

This study uses GARCH-EVT-copula and ARMA-GARCH-EVT-copula models to perform out-of-sample forecasts and simulate one-day-ahead returns for ten stock indexes. We construct optimal portfolios based on the global minimum variance (GMV), minimum conditional value-at-risk (Min-CVaR) and certainty equivalence tangency (CET) criteria, and model the dependence structure between stock market returns by employing elliptical (Student-$t$ and Gaussian) and Archimedean (Clayton, Frank and Gumbel) copulas. We analyze the performances of 288 risk modeling portfolio strategies using out-of-sample back-testing. Our main finding is that the CET portfolio, based on ARMA-GARCH-EVT-copula forecasts, outperforms the benchmark portfolio based on historical returns. The regression analyses show that GARCH-EVT forecasting models, which use Gaussian or Student-$t$ copulas, are best at reducing the portfolio risk.     

Sustainability practices of family firms: the interplay between family ownership and long-term orientation

Sustainability practices are critical for family firms, as they relate directly to the continuity of the business and relationships with important stakeholders, such as members of the local community. Nevertheless, not all family firms wish to adopt sustainability practices. To examine this, we draw upon the socioemotional wealth perspective in order to develop a theoretical model of the direct negative effects of family ownership on the adoption of sustainability practices. We also suggest moderating effects of long-term orientation (LTO) on this link. Our model is tested on a sample of 195 family firms in the tourism and hospitality sector. The results support our hypothesis that family ownership negatively influences the adoption of sustainability practices. Additionally, LTO moderates the relationship between family ownership and the adoption of sustainability practices, such that family owners with a high LTO are more likely to adopt this particular practice compared to those with a low LTO.     

Financialization and Vested Interests: Self-Regulation vs. Financial Stability as a Public Good

I propose an institutionalist analysis of financialization through the lens of Thorstein Veblen, built on some peculiar characteristics of money and related financial instruments in a market-based capitalist economy. Following the case of the overcapitalization of farmlands, studied by Veblen (1919), I argue that modern capitalism is a financialized society dominated by vested interests that rely on financial liberalization-led speculative overcapitalization, often leading to a perverse accumulation process and resulting in systemic catastrophes. Consequently, one of the major constituent institutions of liberal finance, market-dependent selfregulation, proves unable to deal with society-level issues like financial stability. This latter issue must be handled at a systemic level, as a public good. Therefore, specific public regulation and action mechanisms must be designed to maintain society (and dominant vested-interests) within some viability limits to ensure a smooth functioning of the economy.     

Teaching Interactive Media Design

In todays, computer-centered society, designing interactive media has emerged as a new profession. Interactive design is often associated with spread of computers as a communication and interaction tool. However, interactive design has been a staple of artists and designers for many centuries. We present a historical perspective upon interactive design and point out the close relationship of this field with different fields of art and design. We argue that interactive media design is a distinct and evolving field and that it is imperative to teach it as such. In this paper, we have adopted this perspective and detailed a new four-year under-graduate curriculum on interactive media design education. This curriculum stresses the various components of interactive media design and its close relationship with computer science. This revised version was published online in July 2006 with corrections to the Cover Date.     

Consumers’ Perceptions of Corporate Social Responsibility: Scale Development and Validation

Researchers and companies are paying increasing attention to corporate social responsibility (CSR) programs and the reaction to them by consumers. Despite such corporate efforts and an expanding literature exploring consumers’ response to CSR, it remains unclear how consumers perceive CSR and which “Gestalt” consumers have in mind when considering CSR. Academics and managers lack a tool for measuring consumers’ perceptions of CSR (CPCSR). This research explores CPCSR and develops a measurement model. Based on qualitative data from interviews with managers and consumers, the authors develop a conceptualization of CPCSR. Subsequently, model testing and validating occurs on three large quantitative data sets. The conceptualization and the measurement scale can assist companies to assess CPCSR relative to their performance. They also enable managers in identifying shortcomings in CSR engagement and/or communication. Finally, the paper discusses implications for marketing practice and future research.
