Training,productivity and wages in Italy

This paper presents for the first time panel evidence on the productivity and wage effects of training in Italy. It is based on an original dataset which has been created aggregating individual-level data on training with firm-level data on productivity and wages into an industry panel covering all sectors of the Italian economy for the years 1996–1999. I use several modelling specifications and a variety of panel data techniques to argue that training significantly boosts productivity. However, no such effect is uncovered for wages. This seems to suggest that firms do actually reap more of the returns.     

The impact of computer use on earnings in a developing country: Evidence from Ecuador

This paper examines the earnings premium to computer use in a developing country: Ecuador. We use different approaches to examine whether the premium is causal. Controlling for an extensive set of observables, we find an earnings difference between users and non-users of around 20%. Using first differences, the premium drops and is no longer significant in a specification that includes proxies for workers' computer experience and knowledge. Estimates of the impact of the intensity of computer use are also small and in most cases insignificant. Estimates of the pencil premium are substantial in level specifications, but become insignificant in fixed effect specifications. Taken together, also in the setting of a developing country we do not find evidence in favour of the computer premium reflecting a causal impact.     

Productivity,seniority and wages: new evidence from personnel data

Wages may be observed to increase with seniority because of firm-specific human capital accumulation or because of self-selection of better workers in longer jobs. In both these cases, the upward sloping wage profile in cross-sectional regressions would reflect higher productivity of more senior workers. If this were true, the observation of an effect of seniority on wages would depend on the presence of controls for individual productivity. In this paper we replicate, using personnel data from a large Italian firm, the results of the pioneering work of Medoff and Abraham [Quarterly Journal of Economics (1980); The Journal of Human Resources, 15(2) (1981)] in which supervisors' evaluations were used as productivity indicators. Since the validity of supervisors' evaluations as measures of productivity has been widely criticised, we extend the work of Medoff and Abraham using different direct measures of productivity based on recorded absenteeism and misconduct episodes. Both these indicators and supervisors' evaluation suggest that the observed effect of seniority on wages does not reflect a higher productivity of more senior workers. Only at the lowest levels of the firm's hierarchy, the human capital theory contributes to explain the effect of seniority on wages. At least at all other levels, the explanation of the observed upward sloping profile has to be based on theories in which wages are deferred for incentive or insurance reasons.     

Evidence in development of sustainability reporting: a case of a developing country

Current development in social accounting presents an interesting phenomenon. Companies are increasingly engaging in sustainability initiatives and reporting their activities in annual reports, company websites and other media of communication. Unlike previous studies, which have mainly used ex post content analysis of annual reports or other published data to study the relationship between disclosure and possible determinants, this study starts with an interview with the local preparer before the data is triangulated to determine the significant possible determinants. The interview findings are interpreted through institutional theory for possible identification of determinants. Initially, the interview findings indicate that all three mechanisms of isomorphism, the coercive, the normative and the mimetic, contribute to Malaysian company sustainability reporting. However, the regression results prove that only a government linked company in the plantation industry, which is large in size, has a significant amount of sustainability reporting.

Urban agglomeration, wages and selection: Evidence from samples of siblings

The large and significant relationship between city population and wages has been well-established in the agglomeration literature, and the influence of selection effects on this wage premium is important. This paper contributes new evidence to the understanding of this premium by using two different data sets of siblings in order to estimate the agglomeration premium while controlling for unobserved heterogeneity with a family-specific fixed effect. The inclusion of a familial fixed effect into the regression framework makes the city size wage premium insignificant, and there is a large return to a variable representing the correlation between familial ability and residence in an urban area in all of the data sets used in the analysis. The results are discussed in the context of the existing literature, and they demonstrate the importance of family background and selection effects for interpreting the agglomeration premium, which is small in the fixed effects regression.     

State minimum wages and business location: Evidence from a refined border approach

This study examines the effect of state minimum wage changes on new and existing business establishments. It employs a refined border approach in conjunction with other differencing methods to control for unobserved heterogeneous area characteristics. The findings suggest that state minimum wage increases deter new establishments from locating in an area, particularly in industries that rely on low-education workforces, such as the retail and manufacturing industries. However, existing establishments, regardless of industry type, are not found to be adversely affected by minimum wage policy.     

Technological evolution as creative destruction of process heterogeneity: evidence from US plant-level data

Change in evolutionary economics is predicated on the creative destruction of variety. Despite the importance of the concept of variety, or heterogeneity, in evolutionary economic theory, empirical work that examines the character of variety – its extent and its persistence – is still scarce. Drawing on unpublished, micro-level data from the US Bureau of the Census, this paper examines the characteristics of process heterogeneity in selected US manufacturing industries. More specifically the paper has three goals. First, to demonstrate that heterogeneity in plant technologies exists and that it persists over time even within relatively mature industrial sectors. Second, to examine the veracity of the processes that generate and destroy heterogeneity in production technology within narrowly defined industries. Third, to link the heterogeneity of plant-level techniques of production to the pace and direction of technological change at the level of the industry.     

Agricultural productivity,shadow wages and off-farm labor decisions in Nicaragua

The objective of this study is to analyze the decision to work off-farm by male and female farmers in Nicaragua using a three-year unbalanced panel dataset. Shadow income and shadow wages are also estimated. Moreover, to mitigate biases from unobserved individual and farm time-invariant characteristics as well as from sample selection, we apply a semiparametric approach for panel data. Our main findings suggest that shadow wages play a major role in off-farm labor decisions for both males and females. This implies that less labor is allocated to off-farm activities as the opportunity cost for agricultural work goes up. In addition, as the on-farm marginal productivity of households (i.e., shadow income) rises, both males and females reduce the hours they allocate to off-farm activities.     

Substitution and complementarity between managers and subordinates: Evidence from British football

We use data on British football managers and teams over the 1994-2007 period to study substitution and complementarity between leaders and subordinates. We find for the Premier League (the highest level of competition) that, other things being equal, managers who themselves played at a higher level raise the productivity of less-skilled teams by more than that of highly skilled teams. This is consistent with the hypothesis that one function of a top manager is to communicate to subordinates the skills needed to succeed, since less skilled players have more to learn. However, we also find that managers with more accumulated professional managing experience raise the productivity of talented players by more than that of less-talented players. This is consistent with the hypothesis that a further function of successful managers in high-performance workplaces is to manage the egos of elite workers. Such a function is potentially more important the more accomplished the workers are-as indicated, in our data, by teams with greater payrolls.     

Impact of cultural diversity on wages,evidence from panel data

This paper combines individual data from the British Household Panel Survey and yearly population estimates for England to analyse the impact that cultural diversity has on individual wages. Do people living in more diverse areas earn higher wages after controlling for other observable and unobservable characteristics? The results show that cultural diversity is positively associated with wages, but only when cross-section data are used, while panel data estimations show no impact of diversity. Since natives with comparatively higher skills – and wages – tend to self-select into more diverse areas, cross-section analyses may produce upwardly biassed results.     

Environmental regulation,total factor productivity,and enterprise duration: Evidence from China

Environmental regulation has been confirmed to have an important impact on enterprise productivity, which is regarded as a crucial factor of enterprise duration. However, existing studies have paid little attention to how environmental regulation affects enterprise duration. Using firm‐level data from the Chinese Industrial Enterprises Database (2003–2007) and the stochastic frontier analysis method, we estimate enterprise total factor productivity (TFP) and its four decomposed components (scale efficiency change, technological change, factor allocation efficiency change, and technical efficiency change). Meanwhile, we adopt a comprehensive index to measure the environmental regulation intensity. Furthermore, we use the linear probability model and the proportional hazards model to investigate the effect of environmental regulation on enterprise duration through the mediating role of enterprise TFP. The results show that although environmental regulation per se negatively impacts on enterprise duration, environmental regulation can present a synthetic positive effect on enterprise duration due to its positive effect on enterprise TFP. Specifically, environmental regulation significantly mitigates the scale efficiency and technical efficiency of regulated enterprises. It also stimulates regulated enterprises' technological innovation and improves their factor allocation efficiency. In addition, state‐owned and large‐scale enterprises are more malleable when facing environmental regulations. We propose that the government should encourage enterprises to innovate and improve the allocation efficiency of production factors, so as to achieve the purpose of controlling environmental pollution in stages while extending enterprise duration.     

Product Innovation,Credit Constraints,and Trade Credit: Evidence from a Cross‐country Study

This paper studies the relationship between trade credit and innovation. Although trade credit is well researched in the finance literature, its link to innovation has been neglected in prior research. We argue that innovative small and medium‐sized enterprises (SMEs) are more likely to use trade credit than non‐innovative SMEs because of credit constraints and that business partners may have incentives to offer trade credit especially to SMEs with product innovations. The relationship between product innovation and trade credit is empirically examined using a sample of SMEs from 15 European countries. The results of an econometric analysis confirm a positive relationship between innovation and trade credit. In particular, SMEs with product innovations have a higher probability of using trade credit than other SMEs. Moreover, the results suggest that the effect of product innovation is only statistically significant if SMEs report that access to financing or cost of financing are obstacles for the operation and growth of their businesses. Hence, the results point to the relevance of trade credit as a source of short‐term external finance for innovative SMEs that are credit constrained. Copyright © 2011 John Wiley & Sons, Ltd.     

Sticky prices, fair wages, and the co-movements of unemployment and labor productivity growth

This paper studies the co-movements of unemployment and labor productivity growth for the U.S. economy. Measures of co-movements in the frequency domain indicate that co-movements between variables differ strongly according to the frequency. First, long-term and business cycle co-movements are larger than short-term co-movements. Second, co-movements are negative in the short and long run, but positive over the business cycle. A New Keynesian model that combines nominal rigidity on the goods market (sticky prices) and real rigidity on the labor market (fair wages) is shown to be quantitatively consistent with the observed co-movements both in the long term and over the business cycle. However, the model fails to explain the short-term co-movements.     

Analyzing China's productivity growth: Evidence from manufacturing industries

This article examines the growth attributes of manufacturing industries in China for the sample period of 1999–2007. The output growth of manufacturing industries classified under four groups and four regions is decomposed into four components of input growth, scale effect, technical progress, and technical efficiency change. A stochastic frontier model is applied to the translog production function to estimate technical efficiency. Despite the conventional argument that input growth and technical progress are important factors to output growth, the empirical findings show a significant scale effect but a weak technical efficiency change. The contribution to growth from labor has been replaced by human and physical capitals. Structural transformation in the industrial sector is evident, so as regional imbalances.     

Location of trade,return comovements,and diversification benefits: Evidence from Asian country ETFs

Using data from the Asian country ETFs and their MSCI indices, this paper examines whether trading location affects return comovements and diversification benefits. Our empirical results show that the magnitude of return comovements for the Asian country ETFs is higher than the corresponding MSCI indices. Moreover, our empirical findings indicate that the factors, including investor sentiment, market conditions, and economic fundamentals of the U.S. market, have greater effects on the return comovements for the Asian country ETFs than their underlying MSCI indices. Finally, the evidence presents a higher diversification benefit for the Asian MSCI indices than the Asian country ETFs.     

The consequences of private equity acquisitions for employees: new evidence on the impact on wages,employment and productivity

There is growing controversy on the HR consequences of private equity acquisitions, especially when the existing management team is replaced. Much of the debate thus far has centred on the use of limited panels of case studies and industry surveys. This article, in contrast, uses both in‐depth interviews with relevant stakeholders and objective company data to compare firms subject to private equity acquisitions against a control group of non‐acquired firms. Our interviews provide insights into key issues that are investigated in the subsequent empirical analysis. Our core findings are that firms subject to a specific type of private equity acquisition – institutional buyouts – are associated with job losses, lower wages and lower productivity. This evidence is consistent with the notion that this type of private equity acquisition has negative employment consequences without any corresponding improvement in productivity.     

European integration,productivity growth and real convergence: Evidence from the new member states

We estimate the determinants of labor productivity growth in 8 new European Union (EU) member states that joined the Union in 2004. Our focus is on the impact of globalization and EU integration efforts on labor productivity growth. Previous studies test the impact of trade using either exports or trade openness. We also test the impact of imports separately on labor productivity growth. Using panel data for 1995–2006 period, we find that globalization has mixed effects. FDI and exports improve productivity, but imports hurt it. Regarding domestic variables, we find that human capital is the most important source of labor productivity growth in the new member states. There is also considerable adjustment of labor productivity towards EU15 levels, indicating significant “catching up” and hence real convergence. Policy implications of the findings are also discussed.     

Better protected,better paid: Evidence on how employment protection affects wages

This paper empirically establishes the effect of the employer's term of notice on the wage level of employees. The term of notice is defined as the period an employer has to notify workers in advance of their upcoming dismissal. The wages paid during this period are an important element of firing costs and hence employment protection. To find a causal effect, I exploit the exogenous change in the term of notice that resulted from the introduction of a new Dutch law in 1999. Strong evidence is found that a longer ‘dormant’ term of notice leads to higher wages. In my sample, an additional month of notice increases wages by three percent, ceteris paribus.     

The euro and developing country finance: A survey

More than eight years after the introduction of the euro, impacts on developing countries have been relatively modest. Overall, the euro has become much more important in debt issuance than in official foreign exchange reserve holdings. The former has benefited from the creation of a large set of investors for which the euro is the home currency, while demand for euro reserves has been held back by the dominance of the dollar as a vehicle and intervention currency, and the greater liquidity of the market for US treasury securities. Fears of further dollar decline may fuel some shifts out of dollars into euros, however, with the potential for a period of financial instability.
