Teamwork and Intra-Firm Wage Dispersion among Blue-Collar Workers

Using data on a sample of manufacturing establishments in Germany, we find that the use of self-managed teams is associated with increased intra-firm wage inequality between skilled and unskilled blue-collar workers. We also show that moderating factors play an important role. While teamwork interacts positively with employer-provided further training and a production technology of the most recent vintage, it interacts negatively with the age of the establishment and the coverage by a collective bargaining agreement.technology, training, skill-biased organizational change, wage inequality, establishment age, collective bargaining

License Expenditures of Incumbents and Potential Entrants: An Empirical Analysis of Firm Behavior

This paper presents the results of an empirical test concerning the auction model of Gilbert and Newbery (1982). The study uses data on German companies in order to analyze expenditures for technology licenses. Aside of standard control variables the motives for innovation expenditures are also taken into account. We differentiate between firms which intend to secure their present position in the market (incumbents) and those intending to enter a new market (challengers). In line with the prediction of the auction model, it turns out that incumbents show higher expenditures for technology licenses than potential entrants. --Innovation,Licenses,Incumbent versus entrant,Limited Dependent Variables

Do Spillovers Stimulate Incremental or Drastic Product Innovations? Hypotheses and Evidence from German Establishment Data

We estimate the determinants of various types of product innovation. Knowledge spillovers from rivals have a positive impact on incremental innovations. This impact is largely independent of the participation in R&D cooperations. Spillovers exert no such independent influence on drastic innovation activities. The results support the hypothesis that establishments face difficulties in using knowledge that comes from areas they are not familiar with. Establishments exploit spillovers for incremental innovations rather than for drastic innovations. To a limited degree R&D cooperations can help to overcome the difficulties in using spillovers for drastic innovations. Furthermore, our estimates provide evidence that a firm?s own R&D effort and the use of outside information are substitutive. --New Products,Patents,Spillovers,Learning,R&D

Measuring the impact of innovation on firm value: a new approach

Most of the existing empirical literature on the relationship of firm value and knowledge capital is based on the stock market valuation of companies. However, the assets of many firms are not publicly traded, and hence the calculation of market value is limited to a subsample of firms. We suggest to use a credit rating score instead and present an empirical analysis. It turns out that innovative firms, i.e. those with a reasonable knowledge stock, have a better credit rating and thus, as we propose, a higher value. However, too much of innovative activi-ties is seen as risky and the firm value decreases. --Firm Value,Credit Rating,Innovation,Intellectual Property Discrete Regression Models

Are Credit Ratings Valuable Information?

Credit ratings are commonly used by lenders to assess the default risk, because every credit is connected with a possible loss. If the probability of a default is above a certain threshold, a credit will not be provided. The purpose of this paper is to test whether credit ratings contribute valuable information on the creditworthiness of firms. Employing a large sample of Western German manufacturing firms, we investigate loan defaults. First, we estimate Probit models with publicly available information. Subsequently, we additionally use a credit rating and show that it contributes significantly to the regression fit. However, the publicly available information has an independent effect aside of the ratings. Simple calculations demonstrate that the interest rate has to increase significantly to compensate for a possible loss in case of default, if a firm has a weak rating. --Credit Rating,Insolvency,Loan Default,Discrete Regression Models

Profit Sharing and Training

We analyze the impact of profit sharing on the share of workers receiving training. An effect is plausible because: 1) profit sharing is a credible commitment by firms to reward firm-specific skills acquired by formal or informal training, 2) profit sharing may reduce turnover and increase the returns to training, 3) a common payment for the whole workforce leads to peer group pressure to participate in training courses and raises incentives to help co-workers. In order to eliminate possible selectivity effects, we combine a matching approach with difference-in-differences. We identify the proportion of employees participating in profits and differentiate profit sharing according to the percentage of the workers covered by such remuneration schemes. Using German establishment data we find that profit sharing only has a significant effect on training intensity if the majority of the workforce benefits from it.profit sharing, training, matching

Effect of Labor Division between Wife and Husband on the Risk of Divorce: Evidence from German Data

Using German panel data from 1984 to 2007, we analyze the impact of labor division between husband and wife on the risk of divorce. Gary Becker's theory of marriage predicts that specialization in domestic and market work, respectively, reduces the risk of separation. Traditionally, the breadwinner role is assigned to the husband, however, female labor force participation and their wages have risen substantially. Our results suggest that there are gender-specific differences, e.g. female breadwinner-couples have a substantially higher risk of divorce than male breadwinner-couples. In contrast, the equal division does not significantly alter the probability of separation.Divorce, labor division, Germany

Barriers to Entry and Profitability

Barriers to entry are regarded as major impediments to the working of markets. Entry must not necessarily actually take place - the perceived threat of entry may encourage incumbent firms to behave as if they are in a competitive market, even if they are not. We present empirical evidence on effects of perceived threat of entry on profitability. Using information from managers about how they assess the existence of entry barriers a strong impact of these assessments on profitability is confirmed. The number and the relative size of competitors also exert considerable effects. We find no statistically significant relation between the perceived threat of entry and the actual number of firms if the size of the relevant market is taken into account. --Barriers to Entry,Profitability,Discrete Regression Models
