How does the development of urban agglomeration affect the electricity efficiency of resource-based cities?—An empirical research based on the fsQCA method

Urban agglomeration impacts the electricity efficiency of resource-based cities. Under the background, the paths that lead to high level electricity efficiency are not clear. Therefore, it is difficult to guide the socio-economic planning. This paper assumes that the influence of urban agglomeration includes agglomeration and diffusion effect. Then, this paper uses fuzzy-set qualitative comparative analysis (fsQCA) to explore the paths lead to high-level electricity efficiency. The process includes the measurement of electricity efficiency, the selection and quantification of action conditions, and path analysis. Four main conclusions are obtained. First, the positive impact of urban agglomeration on the electricity efficiency of resource-based cities is achieved through the optimal allocation of regional resources. Second, compared with the paths under diffusion effect, the paths under agglomeration effect are more diversified. Third, the effects of two kinds of paths are obvious: the agglomeration of non-resource-based industries to central cities and the diffusion of green production from central cities. Fourth, the diffusion of green production depends on the sustainability of resource-based cities. The research conclusion can improve the energy and sustainability policies of urban agglomerations and resource-based cities, and the improved policies will improve the efficiency of regional resource allocation and will promote the electricity efficiency and sustainability of resource-based cities.     

Urban effects on participation and wages: Are there gender differences?

This paper estimates participation and wage equations using panel data from the United Kingdom to explore gender differences in urban wage and participation premiums. The results suggest a small but economically significant urban participation premium for women but none for men. Results from the wage estimations suggest that after controlling for sample selectivity, observed and unobserved heterogeneity, the urban premium is larger for women. This wage premium is also larger for married or cohabiting women relative to others. There is also evidence of higher urban returns to experience for men and lower urban wage depreciation for both men and women.     

Are China's HSR tariff affordable and economic equitable? An international comparison perspective

While the issues of high-speed rail (HSR) tariff and its impact on equity have always been a hot topic in China, which also attracted the attention of international researchers, research on the level of HSR tariff from the perspective of individual affordability and equity issue have scarcely been considered. This study therefore aims to fill the research gap by quantifying the HSR relative tariff level and its impact on income/regional distribution via introducing a HSR affordability index.Based on the index, we calculate the HSR affordability levels of the main international sample countries with the order of magnitude. Then we expand the analysis of HSR affordability level according to differentiated HSR pricing practice in the selected countries. At the same time, we compare the HSR tariff impact on economic equity among different countries, regions, and social classes.The result indicates that although the absolute level of HSR tariff is low, China is generally in the middle/the lowest and unbalanced position among the sample countries on HSR affordability in terms of expensiveness and economic equity. When we considered the differentiated tariff policy implemented in Europe and Japan, the affordability gap between China and the other countries is further enlarged. Moreover, inequitable distribution of HSR affordability between different income groups and social classes are found larger not only within China, but also higher when compared to the other sample countries.Finally, we conclude that China should implement differentiated HSR pricing system at a larger scale and greater extent based on the Ramsey pricing and Yield management principle to grasp the additional revenue from the high level income group/the developed region and alleviate the economic equity as well. Meanwhile, we also suggest the balance between HSR affordability for passengers themselves and the macro financial affordability for the country as a whole should also be considered in the future HSR pricing regime formulation.     

Managers in transition: An empirical test of Kirton's adaption—innovation theory and its implications for the mid—career MBA

Adaption—innovation theory makes fundamental predictions about the differences in cognitive style of adaptors and innovators. It draws particular attention to the potential for conflict when adaptors and innovators are involved in decision-making and problem-solving in organizations. This paper reports a test of hypotheses derived from the theory in the context of a full-time MBA course for mid-career managers. It draws conclusions relating to the validity of the theory and its implications for the training of these and similar managers in transition.     

How to optimize the allocation of research resources? An empirical study based on output and substitution elasticities of universities in Chinese provincial level

Although significant progress has been made in China's basic research in recent years, there remains a wide gap between research in China and that from developed countries. How to optimize the allocative efficiency of research resources is of great importance for increasing research output. In this paper, using the fixed effect stochastic frontier model based on the translog production function, we estimate output and substitution elasticities of research and development (R&D) inputs at universities in China's provincial level during 2009–2016. We find that the R&D technical efficiency of China's universities, after a rapid growth, has tended to become relatively stable. Improvements of internationalization degree and exogenous R&D capabilities are conducive to promoting R&D technical efficiency, whereas expenditures from government grants inhibit the promotion of R&D technical efficiency; the effects of R&D capital deepening and internet penetration are not evident. The output elasticity of R&D capital is much higher than that of R&D personnel, suggesting that R&D capital is the main driving force of research output. The substitution elasticity between R&D capital and personnel has experienced a change from substitution to complementary since 2014. To realize sustained growth of research output, we should increase R&D input with positive output elasticity or reduce R&D input with negative output elasticity, making the necessary trade-offs according to the substitution relationship between the two R&D inputs.     

An empirical analysis of state labor markets: has worker insecurity shifted wages in the 1990s?

Labor markets in the 1990s have tightened considerably but with a surprising lack of wage inflation. There are several explanations for this behavior, where one of the more prominent explanations is that worker insecurities have depressed wage growth. This study develops an augmented Phillips curve model to test whether there are any structural shifts in wage dynamics in the 1990s. Using state data from 1980 to 1996, the empirical results are consistent with wages becoming more cyclically responsive in the 1990s. Increased long-term unemployment and permanent job losses are associated with the depressed wages in the 1990s, supporting claims that worker insecurity has dampened wage growth.     

Are case studies more than sophisticated storytelling?: Methodological problems of qualitative empirical research mainly based on semi-structured interviews

Qualitative empirical research and case studies have, like any other scientific method, their strengths and weaknesses. But how valid are the findings stemming from such research, particularly when they are base on data gained from interviews? This paper primarily deals with the methodological problems throughout the whole research process. Areas of concerns are: (1) before collecting data and during the whole research process, (2) the process of collecting data, (3) internal validity and making sense of data, (4) external validity of the data and findings, (5) relation between the findings and social sciences as well as social practice. The analysis will reveal a mixed picture concerning the scientific value of qualitative case studies. There is some good news. There is more methodological freedom and room for creativity in qualitative research than it seems at first glance. On the other hand there is a need for a greater methodological awareness particularly concerning possible downsides of subjectivity, the generalisation of the findings, conscious and unconscious biases, influences of dominant ideologies and mainstream thinking. Above all, there is a great need for rational critique. There is great need for a more critical attitude towards (basic) assumptions—particularly, to challenge, question and criticise literally everything systematically and permanently and to put the findings sufficiently in relation to the wider historical context, i.e. epochal ideologies and societal structures. Social science research has to contribute much more to the discussion of values, interests, and ideologies that shape current and future social practices.     

Are some Indian banks too large? An examination of size efficiency in Indian banking

In this paper we use data from the years 1997–2003 to evaluate the size efficiency, as distinct from scale efficiency, of Indian banks. Following Maindiratta [Maindiratta A (1990) J Econ 46:39–56] we consider a bank to be “too large” if breaking it up into a number of smaller units would result in a larger output bundle than what could be produced from the same input by a single bank. When this is the case, the bank is not size efficient. Our analysis shows that many of the banks are, indeed, too large in various years. We also find that often a bank is operating in the region of diminishing returns to scale but is not a candidate for break up.

Co-determination of capital structure and stock returns—A LISREL approach: An empirical test of Taiwan stock markets

Titman and Wessels (1988) utilize a structural-equations model (LISREL) to find out the latent determinants of capital structure. Maddala and Nimalendran (1996) indicate that the problematic model specification causes the poor results in Titman and Wessels’ research. Chang, Lee, & Lee (2009) apply a Multiple Indicators and Multiple Causes (MIMIC) model to re-examine the same issue as Titman and Wessels did but found more convincing results. We extend Titman and Wessels’ research from using a single-equation approach to a multi-equations approach. In addition to the determinants of firms’ capital structure, those of stock returns are determined simultaneously. Literature indicates that a firm's capital structure may affect its stock returns (Bhandari, 1988), and the reverse is true too (Baker and Wurgler, 2002, Lucas and McDonald, 1990, Welch, 2004). Hence, a firm's determinants of its capital structure and those of its stock returns should be decided simultaneously, rather than independently. By solving the simultaneous equations, we examine the empirical relationship between the two endogenous variables: capital structure and stock returns and find out their common determinants as well. Our results show that stock returns, expected growth, uniqueness, asset structure, profitability, and industry classification are the main factors of capital structure, while the primary determinants of stock returns are leverage, expected growth, profitability, value and liquidity. The level of debt ratios and stock returns are mutually determined by the aforementioned factors and themselves.     

Are there major differences in the attitudes and service quality of standard and seasonal employees? An empirical examination and implications for practice

Despite the increased use of seasonal employees by organizations, few studies have been completed on the attitudes and service quality of seasonal office workers. Using Lautsch's classification model, we analyzed the organizational context in which the standard and seasonal workers in this study were employed. Hypotheses were developed based upon the organizational analysis and social exchange theory. Results from archival data obtained from a web‐based organizational survey of 205 clerical and professional workers indicated contrary to expectations, standard and seasonal employees did not significantly differ in terms of perceptions of overall job conditions, perceived organizational support (POS), or job engagement. However, seasonal employees did report significantly fewer opportunities to work on challenging tasks, less comfortable physical working conditions, and less job security than the standard workers. As predicted, standard employees reported significantly higher levels of service quality performance than seasonal employees. Additionally, job engagement mediated the relationship between POS and service quality for both the standard and seasonal employees. Implications for managing seasonal employees are discussed.     

The impact of financial sector development on the economic growth of emerging countries： An empirical study for E-7 countries

Globalization, financial liberalization, financial integration, financial sector, and economic growth have been significant issues for many researchers. The studies have investigated the effects of the above issues to the economic growth of countries both theoretically and empirically. Since there has been conducted an enormous body of work, each of them may be grouped and studied separately. This paper focuses on the impact of financial sector development to economic growth and empirically studies the potential effect on the emerging E-7 countries, consisting of Brazil, China, India, Indonesia, Mexico, the Russian Federation, and Turkey. The study employs panel regression methodology and the data set for modeling Gross Domestic Product （GDP） comprises annual data over 2001-2007, using basic variables which resemble financial sector development, namely market capitalization of listed companies （stock market capitalization）, bank capital to asset ratio, stocks traded, total debt service, foreign direct investments, portfolio investments, real interest rates, and claims on private sector. The analysis indicates that the GDP may be modeled using the above stated macroeconomic variables with considerably high explanatory power, except for the real interest rates and bank capital to asset ratios.     

Are innovation and R&D the only sources of firms’ knowledge that increase productivity? An empirical investigation of French manufacturing firms

The economic literature presents knowledge accumulation as one of the most important characteristics of innovation. The accumulation of knowledge arises from complex and dynamic interactions between a firm??s own internal capacity and external expertise. Research and development (R&D) remains important in the innovation process, but it must be integrated with knowledge from other sources, such as training and knowledge capitalization. This paper investigates the relationship between such knowledge sources and the productivity of French firms. Using asymptotic least squares, a Cobb-Douglas function including R&D, innovation, training expenditure and ISO 9000 certification is estimated for 1,213 French manufacturing firms. Our results show that innovation, training and ISO 9000 certification have a positive and significant impact on firms?? productivity.     

Families of linear efficiency programs based on Debreu’s loss function

Gerard Debreu introduced a well known radial efficiency measure which he called a ??coefficient of resource utilization.?? He derived this scalar from a much less well known ??dead loss?? function that characterizes the monetary value sacrificed to inefficiency, and which is to be minimized subject to a normalization condition. We use Debreu??s loss function, together with a variety of normalization conditions, to generate several popular families of linear efficiency programs. Our methodology also can be employed to generate entirely new families of linear efficiency programs.     

What about theory? The consequences on a widened perspective of social theory

One of the leading debates in social sciences concerns research design. However, in comparative politics, the predominant way conducting research misses out crucial aspects that are central to social theory. This article shows how method and empirical research are highly dependent on the definition of theory. Arguing that theory should not only give an explanation of the social phenomena in question but should also show how this relationship is constructed, this article outlines the consequence of such a perspective, namely that the collection of data should reflect both macro and micro perspectives and the analyses of data should be carried out using mixed methods. In conclusion, such an integrated framework is the most appropriate way to give valuable theoretical feedback, either by examination and revision of already established theories or by a contribution to the construction of new theory in the social sciences. It is important, though, that such a framework is applied in a systematized way.     

Do credit squeezes influence firm survival? An empirical investigation of China

This paper analyses the effect of a “credit squeeze” policy that was set by the Chinese government in 2007, increasing the strictness for firm-level bank loans. We adopt the difference-in-difference (DID) model to compare the survival rate change before and after the policy was implemented. We further explore the mechanism behind how the “credit squeeze” policy reduced the probability of firms surviving the market from perspectives such as financial constraints and ownership structures. The “credit squeeze” policy significantly increased firms’ operating costs and lowered firms’ productivity. In addition, we find that the zombie firm phenomenon existing in state-owned enterprises has a large impact on our estimation. Our results provide practical policy implications regarding the compromise between systematic debt risk and firm survival.     

Does VC fund diversification pay off? An empirical investigation of the effects of VC portfolio diversification on fund performance

The paper tests different theories of how diversification by Venture Capital (VC) firms affects fund performance. The Financial Intermediation and the Resource-based Theory suggest that lower financial risk associated with diversification implies a lower return. However, the assumptions of these theories are questionable in the context of venture capital. We test their validity using data on VC portfolio diversification by industry and country using an original dataset of 649 VC funds originating in the United Kingdom over the period 1981–2000. Results show that higher diversification by industry does indeed lower VC fund success rates. Diversification by geographical region, on the contrary, increases returns.     

Do quality perceptions of health and social services vary for different ethnic groups? An empirical investigation

The United States is now more ethnically diverse than any other time in its history. In 2000, minority ethnic groups comprised 26% of the US population; by 2010, they comprise 35%, and in 2080 they will form the majority of American citizens. And among these ethnic groups, African Americans (12.4%), Hispanics (15.4%) and Asians (4.4%) were the most predominant in 2000. The growth of this segment of the population is not only in terms of numbers but also in terms of economic development. Minority groups are showing marked improvement in income and education levels leading to greater purchasing power. As a result, for‐profit companies are increasingly targeting minority populations with products and promotions specifically designed for specific minority groups. Even non profit organizations such as educational programs, social service and healthcare agencies are striving to design specific services and culturally competent outreach models in order to serve this increasingly diverse marketplace. But despite the strides made by non profit agencies, several studies note the tremendous disparities between the ethnic and racial groups in the seeking and the receipt of health‐care and social services. Additionally, there is limited empirical information about the perceptions of minority consumers. In order to effectively serve minority groups, it is essential to understand their experiences with the non profit service industry and to assess their ongoing concerns. In this study, we focus on two critical components of the non profit world – healthcare and social services. We conducted a survey to compare and contrast the social service and health‐care quality perceptions of three ethnic groups: Caucasians, African‐Americans and Hispanics. Our study, undertaken in collaboration with community health centers, reveals distinct differences in perceptions between the three ethnic groups. Based on our findings, we outline a set of implementable strategies for social service and community health organizations. Copyright © 2010 John Wiley & Sons, Ltd.
