Revisiting the decomposition of cost efficiency for non-homothetic technologies: a directional distance function approach

In the early 1980’s Kopp and Diewert proposed a popular method to decompose cost efficiency into allocative and technical efficiency for parametric functional forms based on the radial approach initiated by Farrell. We show that, relying on recently proposed homogeneity and duality results, their approach is unnecessary for self-dual homothetic production functions, while it is inconsistent in the non-homothetic case. By stressing that for homothetic technologies the radial distance function can be correctly interpreted as a technical efficiency measure, since allocative efficiency is independent of the output level and radial input reductions leave it unchanged, we contend that for non-homothetic technologies this is not the case because optimal input demands depend on the output targeted by the firm, as does the inequality between marginal rates of substitution and market prices—allocative inefficiency. We demonstrate that a correct definition of technical efficiency corresponds to the directional distance function because its flexibility ensures that allocative efficiency is kept unchanged through movements in the input production possibility set when solving technical inefficiency, and therefore the associated cost reductions can be solely—and rightly—ascribed to technical-engineering-improvements. The new methodology allowing for a consistent decomposition of cost inefficiency is illustrated resorting to simple examples of non-homothetic production functions.     

Differences in work–family conflict: which individual and national factors explain them?

This paper contributes to cross-cultural literature on work–family relationships by testing not only hypotheses about the impact of work and family demands and gender at individual level on work–family conflict (WFC), but also at country level. Concretely, several theories commonly used in the literature (role conflict, boundary management and social support theory) are used to analyzed how national culture dimensions affects WFC. Using information about employee residents in each of the countries interviewed in the Second European Quality of Life Survey and also GLOBE dimensions of national culture, the paper shows that the relationship between work and family demands and WFC is universal and equal phenomenon throughout Europe. In line with gender role theory, demanding and stressing work have stronger effects on women’s WFC than on men’s. While opposite to it, household hours also have stronger effect on women’s WFC than on men’s. Moreover, the paper shows that national culture affects how people perceive work–family relationships. In line with integration/segmentation hypotheses derived from boundary management theory, uncertainty avoidance decreases WFC. Moreover, in line with social support, human orientation decreases the level of WFC, especially for men. Eastern Europe and Mediterranean countries have higher levels of WFC, while Scandinavian countries are those that have lower levels of WFC.     

The intellectual structure of human resource management research: a bibliometric study of the international journal of human resource management, 2000–2012

The purpose of this study is to analyze the existing literature on human resource management (HRM) from all the research papers published in The International Journal of Human Resource Management between 2000 and 2012. The authors apply bibliometric methods to identify the main research lines within this scientific field; in other words, its ‘intellectual structure’. Social network analysis is also used to perform a visualization of this structure. The results of the analysis allow us to define the different research lines or fronts which shape the intellectual structure of research on HRM.     

Inflation and interest rates: Some time series evidence from 6 OECD countries

This study examines the time series properties of inflation and interest rates variables using monthly data from 6 OECD countries covering the period 1972.1–1984.8. The analysis focuses on the hypotheses that real rates of interest are constant over time and that movements in nomial rates can be explained by inflation only. These hypotheses are tested by applying both formal and informal test procedures and by carrying out tests both in the time and in the frequency domain. On the whole, the empirical evidence is at variance with these hypotheses. Only in the case of the United States do the results lend some support for the existence of the Fisher relationship.     

Barriers to innovation and public policy in Catalonia

The present paper analyses the link between firms’ decisions to innovate and the barriers that prevent them from being innovative. The aim is twofold. First, it analyses three groups of barriers to innovation: the cost of innovation projects, lack of knowledge and market conditions. Second, it presents the main steps taken by Catalan Government to promote the creation of new firms and to reduce barriers to innovation. The data set used is based on the 2004 official innovation survey of Catalonia which was taken from the Spanish CIS4 sample. This sample includes individual information on 2,954 Catalan firms in manufacturing industries and knowledge-intensive services (KIS). The empirical analysis reveals pronounced differences regarding a firm’s propensity to innovate and its perception of barriers. Moreover, the results show that cost and knowledge barriers seem to be the most important and that there are substantial sectoral differences in the way that firms react to barriers. The results of this paper have important implications for the design of future public policy to promote entrepreneurship and innovation together.

Entrepreneurial intention among University students in Malaysia: integrating self-determination theory and the theory of planned behavior

The present study endeavors to develop a deeper understanding of the motivational processes involved in intentional entrepreneurial behavior. For this purpose, it integrates the social cognitive approach of the theory of planned behavior (TPB) and the organismic theory of motivation of self-determination theory (SDT). More specifically, it tests the role of basic psychological needs of autonomy, competence and relatedness as defined in SDT in shaping university students’ attitudes and intentions toward entrepreneurship. The sample of this study consisted of 438 (Males?=?166, Females =272) 3rd and 4th year university students from four Malaysian Public Universities. The results of the study show that the model strongly explains about 71% of the variance in entrepreneurial intention. Basic psychological needs of autonomy, competence and relatedness have a strong indirect impact on entrepreneurial intention via their attitudinal antecedents: attitude, subjective norm, and perceived behavioral control. This indicates a full-mediational model, where the attitudinal factors operated as transmitters of effects from the distal constructs of SDT on entrepreneurial intention. These findings confirm that both SDT and the TPB provide complementary explanations of the motivational processes of entrepreneurial behavior. The study contributes to the existing knowledge by providing a theory-based understanding of the role of motivations in the formation of entrepreneurial intentions. It opens the way for future research to analyze how alternative motivations may affect new venture creation, survival and success.

     

Employees are satisfied with their benefits,but so what? The consequences of benefit satisfaction on employees’ organizational commitment and turnover intentions

Firms are increasing their efforts to offer benefits that satisfy their employees. However, the attitudinal and behavioral consequences of such satisfaction remain unclear. This article draws on the social exchange perspective and organizational support theory to examine the consequences of three dimensions of employees’ benefit satisfaction on organizational commitment and turnover intention, by considering the mediating effect of perceived organizational support (POS). A hypothesized model is developed and tested using partial least squares analysis on a sample of 870 employees working in Spanish firms. The results show that three dimensions of benefit satisfaction contribute to the development of POS, and that POS mediates their effects on organizational commitment. However, only benefit determination and benefit administration satisfaction have an effect on turnover intention, through the mediation of POS and organizational commitment.     

Liquidity Constraints,Competition, and Markup Cyclicality

This article provides evidence on the relation among financial constraints, competition, and the cyclicality of markups. Based on a long series of industry data from a large number of countries, we find that markups increase in conjunction with the business cycle in environments with higher short‐term financial constraints (liquidity constraints) and more competition. The evidence also suggests that these two elements complement each other: the procyclicality of markups in firms facing both high competition and high liquidity constraints is higher than that explained by each determinant independently.     

Government financial statistics and accounting in Europe: is ESA 2010 improving convergence?

This paper provides an empirical analysis of the impact of ESA 2010 on EU member states, looking at countries both individually and as a whole and analysing the global impact of the adjustments and the partial impacts of each category. Changing the system of national accounts has introduced conceptual and methodological changes, but there has not been any significant variation in the convergence/divergence between government financial statistics and budgetary accounting in reporting deficits. The effect on the deficits reported by individual member states was quite marked however.     

Robust pricing and hedging under trading restrictions and the emergence of local martingale models

We pursue the robust approach to pricing and hedging in which no probability measure is fixed, but call or put options with different maturities and strikes can be traded initially at their market prices. We allow the inclusion of robust modelling assumptions by specifying a set of feasible paths on which (super)hedging arguments are required to work. In a discrete-time setup with no short selling, we characterise absence of arbitrage and show that if call options are traded, then the usual pricing–hedging duality is preserved. In contrast, if only put options are traded, a duality gap may appear. Embedding the results into a continuous-time framework, we show that the duality gap may be interpreted as a financial bubble and link it to strict local martingales. This provides an intrinsic justification of strict local martingales as models for financial bubbles arising from a combination of trading restrictions and current market prices.
