Creative service business and regional performance: evidence for the European regions

The study shows the important impact that the creative service business exerts on the wealth of European regions. The study disentangles the differences between creative service business and other non-creative service business, and explores how much each type of service business contributes to the wealth of the European regions. Most importantly, the study provides robust evidence about the fact that creative service business industries present the highest impact on the wealth of the European regions. The study has important implications for scholars and policymakers, focusing specifically on the type of service business that should be promoted by regional governments.     

State space models for the exchange rate pass-through: determinants and null/full pass-through hypotheses

In this article, we formulate linear Gaussian state space models for the estimation of the exchange rate pass-through of the Brazilian Real against the US Dollar, using monthly data from August 1999 to August 2008. The state space/Kalman filtering framework allows the investigation of some empirical aspects previously suggested in the literature, such as time-varying coefficients and null/full pass-through hypotheses. We also test whether some theoretical ‘determinants’ of the pass-through are statistically significant in the period considered. The principal findings are as follows: (1) the data offer strong support to a time-varying pass-through; and (2) the variance of the exchange rate pass-through, the monetary policy and the trade flow have shown to be relevant determinants of the exchange rate pass-through.     

Partisan Social Happiness

We use a new approach to study questions in political economy that relies on data on the subjective well-being of a large sample of people living in the OECD over the period 1975{1992. Controlling for the personal characteristics of the respondents, year and country fixed effects and country-specific time trends, we find that the data describe social happiness functions for left-wing and right-wing individuals where inflation and unemployment enter negatively. We use these functions to test the root assumption of partisan business cycle models. The evidence is consistent with the hypothesis that left-wing individuals care more about unemployment relative to inflation than right-wingers. Interestingly, we find that individuals declare themselves to be happier when the party they support is in power, even after controlling for macroeconomic variables. The effect of politics is large. Finally, we find that these partisan differences cannot be traced back to income differences. That is, it is misleading to assume|as it is done in the previous literature|that the poor (rich) behave similarly to the left (right). For example, inflation and unemployment do not have differential effects across rich and poor and the happiness levels of these two groups are unaffected by the identity of the party in power. Our findings are hard to explain using median voter models but are to be expected in a partisan world.     

The Random Walk Hypothesis in the Spanish Stock Market: 1980–1992

In this paper we test the random walk hypothesis in the Spanish stock market using disaggregated daily data base spanning the period January 1980 to December 1992. We find that daily returns are strongly correlated and nonlinear dependent. Furthermore, using the variance-ratio test, that is robust to heteroscedasticity, the results suggest that the rejection of the random walk hypothesis cannot be attributed completely to the effects of time varying volatilities. In this sense, the price changes can be potentially predictable over, at least, short time spans.     

Fiscal flows in Europe: The redistributive effects of the EU budget

Fiscal Flows in Europe: The Redistributive Effects of the EU Budget. — In this paper we analyze the redistributive effects of the EU budget among European countries, exploring the relationship between income and fiscal flows, both in per capita terms. Using a new data set on EU budgets from 1986 to 1998, we find that the EU budget has a redistributive effect, though only on its expenditure side. The most redistributive expenditure category is the Regional Fund, followed by the Social Fund and by the guarantee section of the EAGGF. All of them have become increasingly redistributive in time. Total budgetary revenues show only proportionality with income. As regards the net financial balance, three groups of countries are identified, given the treatment they get from the EU budget that cannot be explained by their per capita income levels.     

Female tourists and beach boys: Romance or Sex Tourism?

Previous studies of female tourists and beach boys in the Caribbean have defined these relationships as involving either sex or romance tourism. The objective of this study was to determine which of these definitions was more applicable to relationships in the Dominican Republic. Male and female tourists as well as beach boys and female sex workers were interviewed. Romance and sex tourism were conceptualized as the two ends of a continuum of motivations rather than as distinct categories. Although there was some gender overlap in the continuum of romance/sex motivations, more of the female tourists were located toward the romance end and more of the male tourists toward the sex end of the continuum.     

Search and the market for ideas

We study a market where innovators, who are good at coming up with ideas, can sell them to entrepreneurs, who might be better at implementing them. The market is decentralized, with random matching and bargaining. Ideas are characterized by five salient features: they are indivisible; partially nonrival; intermediate inputs; subject to informational frictions; and difficult to collateralize. This last feature gives rise to a demand by entrepreneurs for liquidity. We determine which ideas get traded in equilibrium and compare this to the efficient outcome, emphasizing the impact of bargaining and liquidity considerations. Among other applications, we study how outcomes in the idea market affect the labor market.     

TIME‐CHANGED MARKOV PROCESSES IN UNIFIED CREDIT‐EQUITY MODELING

This paper develops a novel class of hybrid credit‐equity models with state‐dependent jumps, local‐stochastic volatility, and default intensity based on time changes of Markov processes with killing. We model the defaultable stock price process as a time‐changed Markov diffusion process with state‐dependent local volatility and killing rate (default intensity). When the time change is a Lévy subordinator, the stock price process exhibits jumps with state‐dependent Lévy measure. When the time change is a time integral of an activity rate process, the stock price process has local‐stochastic volatility and default intensity. When the time change process is a Lévy subordinator in turn time changed with a time integral of an activity rate process, the stock price process has state‐dependent jumps, local‐stochastic volatility, and default intensity. We develop two analytical approaches to the pricing of credit and equity derivatives in this class of models. The two approaches are based on the Laplace transform inversion and the spectral expansion approach, respectively. If the resolvent (the Laplace transform of the transition semigroup) of the Markov process and the Laplace transform of the time change are both available in closed form, the expectation operator of the time‐changed process is expressed in closed form as a single integral in the complex plane. If the payoff is square integrable, the complex integral is further reduced to a spectral expansion. To illustrate our general framework, we time change the jump‐to‐default extended constant elasticity of variance model of Carr and Linetsky (2006) and obtain a rich class of analytically tractable models with jumps, local‐stochastic volatility, and default intensity. These models can be used to jointly price equity and credit derivatives.     

Integrating character in management: virtues,character strengths,and competencies

In recent years, character traits in general and virtue-related concepts in particular have been of considerable interest to philosophers, psychological researchers, and practitioners in the business ethics field. Three approaches to character traits can be used to incorporate ethics into organizations: virtues (philosophical approach), character strengths (psychological approach), and competencies (management approach). The aim of this article is to clarify the concept of character traits, or virtues, and provide a unified operational version of it for incorporation into management. To this end, we first discuss the analogy among virtues, character strengths, and competencies. Then, we propose a list of moral competencies that can be implemented in competency-based human resource management.     

How much energy will your NGN consume? A model for energy consumption in next generation access networks: The case of Spain

The contribution to global energy consumption of the information and communications technology (ICT) sector has increased considerably in the last decade, along with its growing relevance to the overall economy. This trend will continue due to the seemingly ever greater use of these technologies, with broadband data traffic generated by the usage of telecommunication networks as a primary component. In fact, in response to user demand, the telecommunications industry is initiating the deployment of next generation networks (NGNs). However, energy consumption is mostly absent from the debate on these deployments, in spite of the potential impact on both expenses and sustainability. In addition, consumers are unaware of the energy impact of their choices in ultra-broadband services. This paper focuses on forecasting energy consumption in the access part of NGNs by modelling the combined effect of the deployment of two different ultra-broadband technologies (FTTH-GPON and LTE), the evolution of traffic per user, and the energy consumption in each of the networks and user devices. Conclusions are presented on the levels of energy consumption, their cost and the impact of different network design parameters. The effect of technological developments, techno-economic and policy decisions on energy consumption is highlighted. On the consumer side, practical figures and comparisons across technologies are provided. Although the paper focuses on Spain, the analysis can be extended to similar countries.
