Specification testing in discretized diffusion models: Theory and practice

We propose two new tests for the specification of both the drift and the diffusion functions in a discretized version of a semiparametric continuous-time financial econometric model. Theoretically, we establish some asymptotic consistency results for the proposed tests. Practically, a simple selection procedure for the bandwidth parameter involved in each of the proposed tests is established based on the assessment of the power function of the test under study. To the best of our knowledge, this is the first approach of this kind in specification of continuous-time financial econometrics. The proposed theory is supported by good small and medium-sample studies.     

Econometric estimation in long-range dependent volatility models: Theory and practice

It is commonly accepted that some financial data may exhibit long-range dependence, while other financial data exhibit intermediate-range dependence or short-range dependence. These behaviours may be fitted to a continuous-time fractional stochastic model. The estimation procedure proposed in this paper is based on a continuous-time version of the Gauss–Whittle objective function to find the parameter estimates that minimize the discrepancy between the spectral density and the data periodogram. As a special case, the proposed estimation procedure is applied to a class of fractional stochastic volatility models to estimate the drift, standard deviation and memory parameters of the volatility process under consideration. As an application, the volatility of the Dow Jones, S&P 500, CAC 40, DAX 30, FTSE 100 and NIKKEI 225 is estimated.     

Marketing practices in the Spanish rural tourism sector and their contribution to business outcomes

This paper sets out to highlight the importance of entrepreneurial and market orientations for the success of enterprises operating out of a rural base. Using these two strategic frameworks, this paper identifies the marketing practices undertaken by rural enterprises, and evaluates their effect on business performance, on the local entrepreneur, and on the rural area itself. Enterprises operating from a rural location play a strategic role in the sustainable development of economies, in the context of which the rural tourism sector particularly stands out. The use of marketing practices appropriate to the aims, capacities and resources of such enterprises is proposed as a mechanism for improving their performance. Using the Spanish rural tourism sector as the basis, a scale measuring marketing practices, and another scale reflecting three different types of outcome – financial, those linked personally to the entrepreneur, and those in terms of development of the rural environment – are proposed and validated, and the effect of marketing practices on the performance of such enterprises is analysed. The findings, which reveal that marketing practices have a significant effect on the achievement of outcomes, have implications of interest for the literature and for practitioners in the rural enterprise sector.     

Entrepreneur: do social capital and culture matter?

This paper analyzes the effect of the individual perceptions of social capital and culture in entrepreneurial aspirations before and after the economic crisis in Western Europe. Following the approach of the Theory of Planned Behavior (Ajzen in Organizational Behavior and Human Decision Processes, 50, 179–211, 1991), we advance the analysis of the effect of the perception of subjective norms in the entrepreneurial intentions. We studied the Total Early-Stage Entrepreneurial Activity (TEA) of twelve countries in 2006 and 2010. The results reveal that the perception of having social networks is significant for the TEA, and it increases after the economic crisis. However, the cultural factors do not have a significant impact, except the one related with the perception of social equality. The results obtained through the double perspective of this analysis (individual’s social capital vs cultural factor of individualistic perspective) offers a certain dilemma when we try to understand the entrepreneurial intntion through the individual’s perception of subjective norms, following the Ajzen’s model. The more individualist is a person, the lower the weight of its social capital. However, the more a person has access to social networks, the greater his entrepreneurial intention will be. This result opens future lines of research focused on understanding the value of the individual’s social capital for different countries and groups of entrepreneurs.

Chief executive officer ability,corporate social responsibility,and financial performance: The moderating role of the environment

This paper seeks to explore how chief executive officer (CEO) ability influences the economic impact of corporate social responsibility strategic decisions. Currently, the evidence on the impact of corporate social responsibility on the value of the company is mixed; in this paper, we aim to observe the moderate role played by this particularity of the CEO in the relationship between socially responsible commitment and financial performance. Our results identify that the most able CEOs make investments in social and environmental practices that lead to greater financial performance; in contrast, the less able CEOs can overinvest or underinvest in an opportunistic way for personal benefit at shareholders' expense. In addition, the role that CEO ability plays in social and environmental strategies is particularly pertinent in munificent environments that foment managerial discretion; in these contexts, high managerial ability leads to investment in socially responsible performance, which benefits shareholders by alleviating moral hazard.     

Collective bargaining in Portugal in the aftermath of the crisis: trends and prospects

This article examines the decline of collective bargaining in Portugal during the recent economic crisis and why, following significant improvements in the economic and political contexts, the number of collective agreements published each year remains lower than before. Drawing on theoretical work on institutional change by Streeck and Thelen (2005) and Baccaro and Howell (2017), it argues that industrial relations institutions in Portugal have been subject to an incremental but transformative process of liberalisation. The analysis of national data and in‐depth interviews with key informants reveals that serial legal amendments since the 1990's weakened unions, converted bargaining into a mechanism to introduce flexibility and wage austerity and reduced incentives for the parties to conclude agreements. While these changes were gradual, their consequences became clear during the crisis. By improving understanding of recent developments in Portuguese collective bargaining, the article enriches knowledge of processes of liberalisation of industrial relations in Europe.     

Motivations of educational tourists in non-English-speaking countries: the role of languages

ABSTRACT

Learning a language or improving one’s foreign language skills may be a key motivator for students to decide to participate in an exchange program as well as choose the destination for their studies. Nevertheless, studies on educational tourism are limited, and there is no research on the motivations of students visiting non-English-speaking countries. To fill this gap, this paper aims to examine the motivations of university students in non-English-speaking destinations by using the push-and-pull framework. Primary data were collected through an online survey from 190 and 205 students who participated in mobility programs in a Spanish university and in a German university respectively. Empirical findings reveal that languages are a key motivating factor for either growing personally through cultural enrichment, or growing professionally. Furthermore, these data allow generic recommendations so that the destinations can attract a larger number of international students.     

Environmental Mutual Funds: Financial Performance and Managerial Abilities

For 15 years, former assistant football coach Jerry Sandusky used his Penn State University perquisites to lure young and fatherless boys by offering them special access to one of the most revered football programs in the country. He repeatedly used the football locker room as a space to groom, molest, and rape his victims. In February 2001, an eye-witness alerted Penn State’s top leaders that Sandusky was caught sexually assaulting a young boy in the showers. Instead of taking swift action against Sandusky, leaders began a cover-up that is considered one of the worst scandals in sports history. While public outcry has focused on the leaders’ silence, we focus on the talk that occurred within the organization by key personnel. Drawing from court documents and internal investigative reports, we examine two euphemism clusters that unfolded in the scandal. The first cluster comprises reporting euphemisms, in which personnel used coded language to report the assault up the chain of command. The second cluster comprises responding euphemisms, in which Penn State’s top leaders relied on an innocuous, but patently false, interpretation of earlier euphemisms as a decision-making framework to chart their course of (in)action. We use this case to demonstrate how euphemistic language impairs ethical decision-making, particularly by framing meaning and visibility of acts, encouraging mindless processing of moral considerations, and providing a shield against psychological and material consequences. Further, we argue that euphemism may serve as a disguised retort to critical upward communication in organizations.     

Is the Chinese stock market really inefficient?

Groenewold et al. (2004) documented that the Chinese stock market is inefficient. In this paper, we revisit the efficiency problem of the Chinese stock market using time-series model based trading rules. Our paper distinguishes itself from previous studies in several aspects. First, while previous studies concentrate on the viability of linear forecasting techniques, we evaluate the profitability of the forecasts of the self-exciting threshold autoregressive model (SETAR), and compare it with the conventional linear AR and MA trading rules. Second, the findings of market inefficiency in earlier studies mainly rest on the statistical significance of the autocorrelation or regression coefficients. In contrast, this paper directly examines the profitability of various trading rules. Third, our sample covers an extensive period of 1991–2010. Sub-sample analysis shows that positive returns mainly concentrate in the pre-SOE reform period, suggesting that China's stock market has become more efficient after the reform.     

Perceived credit constraints in the European Union

The promotion and support of small and medium-sized enterprises (SMEs) is an essential component of policies designed to help improve Europe’s economic performance. A crucial issue is whether SMEs face difficulty obtaining bank loans. Using pre-crisis survey data from 2005 and 2006 for nearly 3,500 SMEs (firms with fewer than 250 employees) in the European Union (EU), we investigate the determinants of perceived bank loan accessibility at the firm level and at the country level. Based on hierarchical (multi-level) binomial logit regressions, our findings show that the youngest and smallest SMEs have the worst perception of access to bank loans. The SMEs in nations with concentrated banking sectors are more positive about loan accessibility. In addition, a high fraction of foreign-owned banks is associated with improved perception of loan accessibility in the EU 15 but not in the EU 10.
