To challenge the world view or to flow with it? Teaching sustainable development in business schools

This paper explores the fundamental question of what ‘responsibility’ means to different sets of world views adopted implicitly by business students. The exploration adopts the stakeholder theory and three subsets of the Friedman mentality to explain how individuals may value sustainability initiatives. Subsequently, it explores whether it is better to flow with the dominant economic‐driven world view as prescribed by the business school or to challenge it in order to cultivate business students with sustainability‐driven values. The conclusion highlights implications for business and management education, as well as the role of entrepreneurship to promote sustainability values.     

Capital-induced labor migration in a spatial Solow model

Journal of Economics - In this work we consider labor mobility in the spatial Solow model for economic growth. Besides considering that labor diffuses from regions with higher density to regions...     

Market illiquidity and bounds on European option prices

The paper analyses the impact of illiquidity of a stock paying no dividends on the pricing of European options written on that stock. In particular, it is shown how illiquidity generates price bounds on an option on this stock, even in the absence of other imperfections, such as transaction costs and trading constraints, or the assumption of stochastic volatility. Moreover, price bounds are shown to be asymmetric with respect to the option price under perfect liquidity. This fact explains, under some conditions, the appearance of a smile effect when the implied volatility is estimated from the mid-quote.     

Rational Underdevelopment*

We propose a two‐region two‐sector model of uneven development, where technological change benefits either the lagging or the leading region. In this framework interregional transfers may lead to persistent underdevelopment; by raising wages, transfers reduce the chance of the backward region adopting a new technology and taking off. Due to uncertainty about which region benefits from technological change, the backward region may rationally choose to remain underdeveloped, while the advanced region continues to pay transfers. The model provides a rationale for cases, such as Italy's Mezzogiorno, where the same rich region subsidizes the same poor region on a continuous basis.     

ASYMMETRIC INFORMATION AND EXCHANGE OF INFORMATION ABOUT PRODUCT DIFFERENTIATION

We introduce asymmetric information about consumers’ transportation costs (i.e., the degree of product differentiation) in the model of Hotelling. When transportation costs are high, both firms have lower profits with asymmetric information than with perfect information. Contrarily, if transportation costs are low, both firms may prefer the asymmetric information scenario (the informed firm always prefers the informational advantage, while the uninformed firm may or may not prefer to remain uninformed). Information exchange is ex‐ante advantageous for both firms, but ex‐post damaging if transportation costs turn out to be low. If the information is unverifiable, the informed firm does not represent a reliable source of information, since it always prefers to announce that transportation costs are high and there is no contract that induces truthful revelation.     

Sectoral Heterogeneity in New Service Development: An Exploratory Study of Service Types and Success Factors

The service industry is of fundamental relevance for the economies of industrialized countries, as the service industry produces the highest growth in the gross domestic product. In this regard, new service development (NSD) represents a critical resource for competitive survival and a decisive factor of growth in the service industry. However, service firms across many industries are increasingly faced with the challenge of determining how best to manage their development of new service offerings. Although researchers have shown growing interest in NSD issues, this area is still underutilized. Furthermore, although the heterogeneity of the service industry has been emphasized for years, the current body of research on NSD mainly focuses on specific service environments, providing data that are often not comparable across different service sectors. Additionally, there is no study to date that comprehensively examines innovation activities and the relevance of service innovations’ success factors within different service industries. The aim of this exploratory study is to establish a more balanced picture of the nature of innovation activities in terms of NSD characteristics and success factors in the heterogeneous service industry. From this perspective, this paper begins with an examination of the factors that contribute to the success of NSD. Based on a meta‐analysis of new service success factor studies, 17 different success determinants are classified and aggregated to service‐related success determinants. Subsequently, a cluster analysis of 1016 service companies is used to identify different service innovation types. For the service sector, four service innovation types are determined: efficient developers, innovative developers, interactive adopters, and standardized adopters. Furthermore, based on interviews with service innovation managers, the previously identified success factors are examined for each innovation type using a standardized survey. Finally, based on the results of this exploratory study, the paper concludes with recommendations for NSD management and research propositions for each service innovation type. These propositions support innovation managers to successfully manage service innovations for the innovation type they are operating in.     

The transmission mechanism in a changing world

The paper aims to identify those factors that cause changes in the speed and strength of the international transmission of output shocks from the USA to specified European economies. These factors are identified through the use of generalized impulse response functions conditioned on histories defined by an abrupt transition VAR. The chosen transition variables comprise changes in exchange rates, financial prices, international capital flows, trade links and monetary policy instruments. Besides the identification of asymmetric responses, the proposed model is useful in analyzing the strong effect of the recent US recession on the European economies and changes in business cycle synchronization over time.

Insuring Banks Against Liquidity Shocks: The Role of Deposit Insurance and Lending of Last Resort

Abstract.  It has long been recognized that banks' simultaneous provision of monitoring and liquidity services is advantageous but leaves them susceptible to liquidity shocks that may culminate in a system failure. Because a system failure is costly, this provides a rationale for adopting arrangements, including a lender of last resort and deposit insurance (DI), to insure banks against liquidity shocks. These arrangements have proven themselves very successful, but they have also been the source of problems. Researchers have identified some of the main sources of these problems and have suggested ways to improve the design of these arrangements, but there are still many issues that remain unaddressed. This paper reviews the literature on the two arrangements that most countries have adopted to insure banks against liquidity shocks, a lender of last resort and DI, and compares the design of these arrangements across countries. The paper ends with a brief summary of the key lessons learned about the design of these arrangements and the issues related to them that remain unaddressed.     

Hysteresis and sluggishness in Portuguese unemployment, 1977–88

The phenomenon of unemployment persistence led to the development of alternative theories of unemployment. Among these the ‘hysteresis’ concept by Blanchard and Summers (1987) received a wide interest. Based on this notion we developed a generalized model that nests Blanchards and Summers' theory. Using this framework we conducted an empirical investigation for the Portuguese labour market (1977–88). The results obtained point towards the existence of labour demand sluggishness, wage inertia and unemployment hysteresis. The model also suggests the existence of a rather inelastic labour demand curve.     

Applications of Fuzzy Regression in Actuarial Analysis

In this article, we propose several applications of fuzzy regression techniques for actuarial problems. Our main analysis is motivated, on the one hand, by the fact that several articles in the financial and actuarial literature suggest using fuzzy numbers to model interest rate uncertainty but do not explain how to quantify these rates with fuzzy numbers. Likewise, actuarial literature has recently focused some of its attention in analyzing the Term Structure of Interest Rates (TSIR) because this is a key instrument for pricing insurance contracts. With these two ideas in mind, we show that fuzzy regression is suitable for adjusting the TSIR and discuss how to apply a fuzzy TSIR when pricing life insurance contracts and property‐liability policies. Finally, we reflect on other actuarial applications of fuzzy regression and develop with this technique the London Chain Ladder Method for obtaining Incurred But Not Reported Reserves.
