Trade credit in SMEs: a quantile regression approach

This article analyses the determinants of the trade credit in Spanish manufacturing small and medium-sized enterprises (SMEs) from a new perspective. Specifically, we focus on the relationship between trade credit and other relevance financial resources: bank credit and self-financing. For the first time in the literature, a quantile regression approach is used, which takes into account the heterogeneity of firms in different quantiles of trade credit distribution. Our results show that the relationship between trade credit and other financial sources presents dissimilarities, including differences in sign, on SMEs with different degrees of trade credit. Our findings help to clarify the confusing results achieved in previous research on this topic.     

An analytic hierarchy process for ranking operating costs of low cost and full service airlines

This paper develops an application of the analytic hierarchy process to rank the operating cost components of full service and low cost airlines. It takes into account the financial balance sheets and answers to a questionnaire submitted to the managers of selected airlines. The results suggest that the analytic hierarchy process can be appropriately used to obtain the ranking of the costs taking into account different views: financial, management and operative. Rental, office equipment and other supplies costs show the highest importance in the cost ranking, both for full services and low cost airlines. The robustness of the results is tested by Monte Carlo analysis.     

Global Imbalances: The Role of Emerging Asia

This paper investigates the role played by emerging Asia in the emergence and evolution of the global trade imbalances. Based on simulations in a general-equilibrium model of the world economy, we find that a productivity slowdown in the nontradable sector of these economies in the second half of the 1990s fits regional macroeconomic developments relatively well, but has limited spillover effect to the United States trade balance. In contrast, an increase in the desired level of emerging Asia net foreign assets starting in 2001 not only fits regional developments relatively well, but also has a significant spillover effect to the United States.     

Measuring the Returns to Networking and the Accumulation of Social Capital: Any Evidence of Bonding,Bridging, or Linking?

This article presents analyses of individual investment in social capital using both the British Household Panel Survey (BHPS) and the UK Time Use Survey (2000) (UKTUS). We suggest a general theoretical framework that could possibly explain individual investment in various forms of social networking. Measures of social capital are then constructed in an attempt to capture the extent of individual investment in bonding, bridging, and linking networks. These measures, together with other socioeconomic indicators, are used as explanatory factors in wage equations, estimated using ordered probit, OLS, and instrumental variable approaches. We are unable to identify any consistent returns from investment in bonding and bridging networks. In contrast, the evidence suggests that any returns to investment in the development of linking social capital simply derive from the positive signals that group membership may transmit to potential employers. Our results underline the contrast between studies that consider social capital as an attribute of communities, as opposed to individuals, in that we find a negative return to social activity at the level of the individual.     

Persistence of innovative activities, sectoral patterns of innovation and international technological specialization

In this paper, we focus on the role of persistence and heterogeneity of innovative activities at the level of the firm in determining the patterns of technological change in different industries and countries. We ask: are persistence and heterogeneity associated with higher degrees of concentration in innovative activities, stability in the ranking of innovators, and lower degrees of entry and exit in the population of innovators? Or, do the patterns of innovation depend on other variables like firm size and industrial concentration? Moreover, what are the relationships between the patterns of innovative activities, their determinants, and the technological specialization of countries? We compute indicators of persistence and heterogeneity using the OTAF-SPRU patent database at the firm level for five European countries over the period 1969–1986 for 33 technological classes. Then, we estimate the relationships between our indicators of the sectoral patterns of innovative activities and international technological specialization on the one hand, and our indicators of persistence, heterogeneity and market structure on the other. Results show that persistence and asymmetries are important (and strongly related) phenomena that affect the patterns of innovative activities across countries and sectors, while the role of market structure variables is less clear. Finally, international technological specialization is associated to a competitive core of persistent innovators.     

Information Acquisition in Financial Markets

Previous work on information and financial markets has focused on a special set of assumptions: agents have exponential utility, and random variables are normally distributed. These assumptions are often necessary to obtain closed-form solutions. We present an example with alternative assumptions, and demonstrate that some of the conclusions from previous literature fail to hold. In particular, we show that in our example, as more agents acquire information, prices do not necessarily become more informative, and agents may have greater incentive to acquire information. Learning can therefore be a strategic complement, allowing for the possibility of multiple equilibria.     

Understanding second home owners who do not rent—Insights on the proprietors of self-catered accommodation

The objective of this study was to understand the actual self-concept and the concept of second homes as well as the behaviour of second home owners who do not let their properties. Low utilisation of these homes and apartments by the owners has led to heavy economic and social costs. So far, academic research has strongly focused on (1) quantity and quality of second homes (rented and non-rented), (2) on distribution systems and intermediaries as well as (3) on holiday home customers. However, research on the owners themselves has been scarce and sketchy. Using a self administrated questionnaire for the collection of the data and the following discriminant analysis, lifestyle patterns were discovered. Results from 1045 non-renters in the Alpenarena area of Switzerland, indicate that the level of letting of second homes depends on when the second home was purchased and on the owner's age. Owners’ self-concepts and concepts of their second homes also varied with age. The findings are used to suggest strategies and incentives to encourage owners to let second homes.
