Changes in women’s and men’s child care time in China, 2004–2011: the contributions of cohort replacement and intra-cohort change

With the rapid social and economic changes in China, increasing attention has been paid to issues related to child care, such as maternal work and child care, child care support sources, and work-family conflict. But the change in women’s and men’s child care time in the last decade remains under-researched. I use cross-sectional data from the 2004–2011 China Health and Nutrition Survey and linear decomposition regression techniques to examine the mechanisms generating structural change in child care time for men and women. I find that overall women’s child care time is slightly decreasing because the contributions of intra-cohort change and cohort replacement are offsetting one another. However, men’s childcare time is increasing during the same time period because of processes of intra-cohort change. Trends in women’s childcare time indicate a positive but small cohort replacement effect, whereas men’s childcare time is largely impacted by a positive intra-cohort change effect. These results highlight the mechanisms through which the gendered division of childcare time inside Chinese families has been shifting in the direction of increasing egalitarianism from 2004 to 2011.     

Enhancing the green efficiency of fundamental sectors in China’s industrial system: A spatial-temporal analysis

Due to sectoral interactions in the economy, the overall green efficiency (GE) of China’s industrial system relies heavily on fundamental sectors that contribute substantial energy to the supply chain production of other sectors but shows low sectoral GE. For the three fundamental sectors in China’s industrial systems, namely the smelting and pressing of nonferrous metals (SPNFM), the processing of petroleum, coking, and nuclear fuel (PPCNF); and the manufacturing of nonmetallic mineral products (MNMMP), we employed a three-stage data envelopment analysis (DEA) model to measure GE in the fundamental sectors in 30 provinces from 2010 to 2015. We then adopted a stochastic frontier analysis (SFA) model to evaluate the influence of technological innovation (TI), industrial agglomeration (IA), environmental regulation (ER), and intraindustry competition (IC). The results showed that GE in the three fundamental sectors varied spatially. Specifically, TI promoted GE in MNMMP, but the effect was not obvious in the SPNFM and PPCNF sectors. Moreover, ER had positive impacts on GE in the fundamental sectors. The effects of IA and IC on GE in the fundamental sectors varied in direction and strength. After eliminating the impacts of environmental effects and statistical noise, the real GE in the three fundamental sectors varied significantly compared to the comprehensive GE. Policy opportunities for enhancing GE in the fundamental sectors mainly lie in region-specific policy and regulations that avoid a “one-size-fits-all” governance approach.     

Using DEA for measuring teachers’ performance and the impact on students’ outcomes: evidence for Spain

This research contributes to the ongoing debate about differences in teachers’ performance. We introduce a new methodology that combines production frontier and impact evaluation insights that allows using DEA as an identification strategy of a treatment with high and low quality teachers within schools to assess their performance. We use a unique database of primary schools in Spain that, for every school, supplies information on two classrooms at 4th grade where students and teachers were randomly assigned into the two classrooms. We find considerable differences in teachers’ efficiency across schools with significant effects on students’ achievement. In line with previous findings, we find that neither teacher experience nor academic training explains teachers’ efficiency. Conversely, being a female teacher, having worked five or more years in the same school or having smaller class sizes positively affects the performance of teachers.     

Women’s entrepreneurship: A model of business-family interface and performance

Recently, there are renewed calls to develop new models addressing the intricacies of women-owned businesses and the women that head them. A new conceptual model of women’s entrepreneurship that involves relationships between business-family-interface and firm performance is introduced in our paper. We test the model based on data from countries around the world and show that the model’s links depend on the country context. As a result, we identify new boundary conditions to the domain of female entrepreneurship. Implications are discussed.     

Linking entrepreneurial and market orientation to the SME’s performance growth: the moderating role of entrepreneurial experience and networks

Entrepreneurial orientation and market orientation (EO and MO, respectively) have received extensive research attention in the past several decades. Although scholars widely agree that both MO and EO are critical to firms’ performances, a better understanding is still needed about how market and entrepreneurial orientation develop over time as well as their relative impact on the growth of the SME’s performance. This study does not consider MO and EO as generic resources that always positively influence firms’ performances; instead, it tries to explore contingent elements, such as social and business networks and accumulated entrepreneurial experience. The hypotheses were tested on 191 small and medium-sized electronic firms located in an Italian geographical cluster during two periods: 2005 and 2016. This study suggests that SMEs, which develop social networks, may enjoy considerable advantages from entrepreneurial and market orientation, improving their performance benefits. Moreover, our results show that previous entrepreneurial experience, when specific, can reinforce the impact of entrepreneurial and market orientation on firms’ performance growth. This analysis makes several important contributions to the management literature on the strategic orientation of firms, the entrepreneurial experience and network development.

     

Incentive regulation and performance measurement of Taiwan’s incineration plants: an application of the four-stage DEA method

The aim of this paper is to provide a technical efficiency assessment of Taiwan’s incineration plants as the basis of incentive regulation schemes. We integrate the four-stage approach with Simar and Wilson’s (in J Econom 136:31–64, 2007) double bootstrapping to filter out the impacts of external variables in the efficiency measurement. Empirical results show that there is room for 15 % cost reductions and capacity, ownership, location and experience are all influential in improving the performance of these plants. We also demonstrate how the results can be applied to modify a yardstick incentive scheme.     

Dimensional effects of Korean SME’s entrepreneurial orientation on internationalization and performance: the mediating role of marketing capability

This study examines how three different dimensions of entrepreneurial orientation (proactiveness, innovativeness, and risk-taking) each determine internationalization strategies and enhance international performance among small and medium-sized enterprises (SMEs) through the mediating role of marketing capabilities. An integrative theoretical framework built on international entrepreneurship and a resource-based approach was tested in the context of Korean SMEs. Analyses of 401 survey data collected from Korean exporting SMEs revealed the differential effects of each entrepreneurial orientation and the mediating effect of marketing capability on internationalization strategies and performance. Proactiveness and risk taking appeared to function as significant antecedents of marketing capability. Marketing capability, in turn, significantly decreased internationalization scope and increased the financial performance of Korean SMEs, though it did not influence internationalization scale. This study further confirms that the mediating role of marketing capability in entrepreneurial orientation-performance relationships vary by entrepreneurial orientation dimensions. Taking the direct and indirect roles of the entrepreneurial orientation dimensions together, this study recommends the critical prioritization of risk-taking over proactiveness. It extends previous approaches to the triad of resource–capability–performance. Theoretical contributions and insightful managerial implications are also provided.     

Boundary problems with the “Russell” graph measure of technical efficiency: a refinement

In an influential paper, Färe and Lovell (J Econ Theory 19:150–162, 1978) proposed an (input based) technical efficiency index designed to correct two fundamental inadequacies of the Debreu-Farrell index: its failure to satisfy (1) indication (the index is equal to 1 if and only if the input bundle is technically efficient) and (2) weak monotonicity (an increase in any one input quantity cannot increase the value of the index). Färe et al. (1985) extended the index to measure efficiency in the full space of input and output quantities. Unfortunately, this index fails to satisfy not only indication and monotonicity at the boundary (of output space), but also weak monotonicity. We show, however, that a simple modification of the index corrects these flaws. To demonstrate the tractability of our proposal, we apply it to baseball batting performance, in which zero outputs occur frequently.     

Diversification strategy,CEO management style and firm performance: an application of Heckman’s two-stage method

This paper aims to explore whether CEOs’ management style as agents or as stewards, which depends on their psychological and situational characteristics, moderates the effect of the diversification strategy on firm performance. After applying Heckman’s two-stage method to control econometrically for endogeneity bias in empirical work, results demonstrate that the relationship between diversification and profitability varies significantly depending on the management style of the diversifying CEO.

STEM selves: Women’s identity projects and their assessment of future employers in technical fields

In this paper, we take an identity project perspective on careers to explore how job seekers assess potential employers. Identity projects are individuals’ self-definitions in the light of their career development and personal aspirations and have the potential to further our understanding of careers. Drawing on focus group discussions of women seeking employment in STEM, we find four identity positioning strategies through which the women assess future employers. Our analysis illustrates the role of organizational images for shaping and realizing individuals’ identity projects. We contribute to research on identity projects by extending the concept’s focus to include job seekers as external organizational stakeholders and provide insight into their identity positioning. Furthermore, our study enhances the understanding of organizational image in the context of employee recruitment by outlining how individuals position themselves in relation to the organizational images they construct when reflecting on their identity projects and on the institutional context. Overall, we develop a more nuanced approach to understanding women’s interpretations of organizational identity claims (e.g., gender diversity claims) and thus extend current theorizing on recruiting women to STEM.     

The productivity and performance of Australia’s major banks since deregulation

The aim of this study is to present some measures of the performance of banks operating in Australia since the deregulation of the Australian financial system in early 1980s; including the periods of financial market instability (the early 1990s and mid to late 2000s). In undertaking this measurement two approaches will be used. The first simply applies standard financial indicators. The second approach applies data envelopment analysis (DEA), to determine Malmquist indices of the levels of and the changes in the efficiency and productivity of Australian banks. The empirical results demonstrate the effect of deregulation and periodic financial crisis’s on the performance of individual banks, and the major part of the Australian banking sector. Overall the productivity performance of the Australian banks tended to improve considerably in those periods of strongest economic growth (i.e. the mid 1980s and 2000s).     

Dynamic connectedness of China’s green bonds and asset classes

This paper quantifies the co-movement and time-varying integration between China's green bonds and other asset classes across different time domains using the wavelet coherence and time-frequency connectedness model based on the time-varying parameter VAR (TVP-VAR). First, we predominantly detect a strong positive co-movement of green and conventional bonds, especially in the medium and long term. Second, strong bidirectional spillovers exist between green bonds and treasury, corporate, and financial bonds regardless of the time horizon. Lastly, cross-market spillovers between the green bonds and the stock, energy, low-carbon stock market were quite limited in the short-run but strengthened towards the long-term except during the 2015 China stock market crash and the COVID-19 recession when short-term integration rose sharply. The results document some practical enlightenment for investors and policymakers with various time horizons.     

Estimation of technical change and price elasticities: a categorical time–varying coefficient approach

We propose a categorical time-varying coefficient translog cost function, where each coefficient is expressed as a nonparametric function of a categorical time variable, thereby allowing each time period to have its own set of coefficients. Our application to U.S. electricity firms reveals that this model offers two major advantages over the traditional time trend representation of technical change: (1) it is capable of producing estimates of productivity growth that closely track those obtained using the Törnqvist approximation to the Divisia index; and (2) it can solve a well-known problem commonly referred to as “the problem of trending elasticities”.     

The impact of the shutdown policy on the asymmetric interdependence structure and risk transmission of cryptocurrency and China’s financial market

By taking Bitcoin, Litecoin, and China’s gold and RMB/US dollar exchange rate market as research objects, this paper apply the MF-ADCCA and time-delayed DCCA methods to study the impact of China’s mainland shutdown of cryptocurrencies trading on the non-linear interdependent structure and risk transmission of cryptocurrencies and its financial market. Empirical results show that the cross-correlation between cryptocurrencies and China’s financial market has a long memory and asymmetric multifractal characteristics. After the shutdown, the long memory between cryptocurrencies and Chinese gold has weakened, and the long memory between cryptocurrencies and the RMB/US dollar exchange rate market was strengthened. China’s shutdown policy has a certain risk prevention effect. Specifically, after the implementation of the policy, the risk transmission of cryptocurrencies to China’s financial market has weakened, but the influence of China’s financial market has gradually strengthened.     

Modeling and simulation of the quality’s entropy

The aim of the present study is to define quality entropy as well as to illustrate some of its properties. The simulation of the mathematical model for quality entropy shall be performed by means of specialized software for mathematical problem simulation, such as Microsoft Excel that we have employed for this particular study. Our aim is to prove that quality entropy may be expanded to the notions of Markov source of quality and Bernoulli source of quality, by analogy with the Markov and Bernoulli sources employed in information theory. Likewise, the present study delineates some aspects regarding tolerance to quality entropy. The subject of entropy and its application of the management of quality has been approached by other authors as well (Dinu and Vod?, Revista Calitatea-acces la succes, anul 8(4): 60–61, 2007; Dinu, Revista Calitatea-acces la succes, anul 8(5): 62–63, 2007; Georgescu-Roegen, Legea Entropiei ?i Procesul Economic, 1979; Stamatiu, Proceedings of the 7th International Conference on Quality, Reability and Maintainabilty, 2000; Stamatiu, Proceeding of the 18th International Conference on Quality, Reliability and Maintainability, 2002). Through our transdisciplinary approach, we would like to contribute to the development of this subject.
