physical appearance and earnings further evidence the literature contains numerous studies on earnings differentials based on age race and gender comparatively few studies have examined differences in labour market success related to physical appearance using three waves of data collected at two organizations this paper tested for earnings differentials among workers based on their self reported appearance significant earnings premiums for attractiveness were found for women but not for men

can learning affect exchange rate behavior the case of the dollar in the early 1980 s this paper demonstrates that a change in parameters of the money market that is not immediately understood will affect the behavior of exchange rate forecast errors while the market is learning the analysis is applied to the behavior of u s dollar german mark forecast errors during the early 1980 s when the market appeared to systematically underpredict the strength of the dollar consistent with this observation empirical estimates of implied forecast errors based upon bayesian learning suggest that forecast errors would have been on average negative during the period as the market came to realize the increase in u s money demand

the impacts of government ideology on innovation what are the main implications abstract this study investigates the relationship between government ideology and technical innovativeness of the whole country by using multinational panel data covering 110 countries from 1995 to 2015 and by employing comprehensive indicators for technical innovation i e trademark and patent application in empirical research we utilize the panel generalized method of moment gmm technique to introduce dynamic variables in order to avoid the bias caused by potential endogeneity next we generate three cross items to examine whether the effect of government ideology on technical innovation differs under different circumstances we then change the measurement of government ideology to assure the reliability of our empirical results further investigate whether the changes of political ideology influence technical innovation and carry out a robustness test by dividing the whole sample into two sub samples based on the level of democracy by employing two samples which limited by 3 main coalition parties in government at most such as re elected government and non alternated government in countries overall the empirical results show that a leftist ruling party inhibits the progress of technical innovation whereas a right wing ruling party promotes the appearance of new technology the effect of government ideology on innovation is not similar under some circumstances more evidence is presented by using two dummy variables to represent left wing and right wing

technological innovation and the distribution of employment growth a firm level analysis this work studies the firm level relationship between different types of innovative activities and employment growth rates improving on previous investigations on the topic it combines a detailed analysis of the effects of product and process innovation on average employment growth with a broader outlook on the whole conditional employment growth distribution results show that product innovation especially in terms of good new to the entire market has a positive effect on employment growth this role is likely to be particularly relevant for both fast growing and shrinking firms process innovation appears instead to have less clear cut dynamics consistently with existing evidence among different types of process innovation the introduction of novel auxiliary processes appears to be more positively linked with employment growth

beauty and the labor market the authors examine the impact of looks on earnings using interviewers ratings of respondents physical appearance plain people earn less than average looking people who earn less than the good looking the plainness penalty is 5 to 10 percent slightly larger than the beauty premium effects for men are at least as great as for women unattractive women have lower labor force participation rates and marry men with less human capital better looking people sort into occupations where beauty may be more productive but the impact of individuals looks is mostly independent of occupation suggesting the existence of pure employer discrimination copyright 1994 by american economic association

learning about intervention target zones abstract this paper provides a framework for evaluating how market participants beliefs about foreign exchange target zones change as they learn about central bank intervention policy we generalize the standard target zone model to allow for intra marginal intervention intra marginal intervention implies that market participants beliefs about the target zone can be determined from their beliefs about the likelihood of intervention we then estimate a daily probability of intervention model for the period following the louvre accord we find that the market s views of intervention target zones would have varied quite a bit over time even over this relatively stable period

beauty in the classroom are german students less blinded putative pedagogical productivity due to professors pulchritude peculiar or pervasive given that instructional student ratings measure differences in pedagogical productivity this study examines whether perceived attractiveness of german university teachers impact on these differences apart from some refinements and adjustments to idiosyncracies of the german system of higher learning the quantitative analysis widely follows the strategy of the seminal work by hamermesh and parker 2005 based on us data in comparison to findings for the usa perceived attractiveness of teachers is found to have if at all only a weakly significant and quantitatively less important impact on the evaluation outcomes

towards green growth how does green innovation affect employment abstract we examine the relationship between green innovation and employment from data taken from the spanish technological innovation panel pitec for period 2007 2011 the increasing relevance of environmental issues for the spanish economy its unemployment problem and the uniqueness in its innovation structure make it a proper and interesting context to investigate green innovation dynamics we find a positive relationship between green innovation and employment and the relationship is stronger for firms in the so called dirty industries in addition we show that the relationship is positive for firms that introduce green innovation voluntarily as compared to firms that introduce green innovation merely to comply with regulations a positive and significant relationship is also found between employment and firms that report an increase in the degree of importance paid to green innovation

beauty productivity and discrimination lawyers looks and lucre we propose models with an ascriptive characteristic generating earnings differentials and causing sectoral sorting allowing us to distinguish among sources producing such differentials we use longitudinal data on a large sample of graduates from one law school and measure beauty by rating matriculation photographs 1 betterlooking attorneys who graduated in the 1970s earned more than others after 5 years of practice an effect that grew with experience 2 attorneys in the private sector are better looking than those in the public sector differences that rise with age these results support theories of dynamic sorting and customer behavior

r d and employment an application of the lsdvc estimator using european microdata abstract the job creation effect of business r d is tested applying the dynamic lsdvc estimator to a longitudinal database covering 677 european companies over the period 1990 2008 job creation is detected in services and high tech manufacturing but not in traditional sectors

playing with the band dynamic effects of target zones in an open economy this paper applies techniques of regulated brownian motion to a model of a small open economy to investigate how bands on fundamental driving variables affect the realization of the nominal exchange rate the real exchange rate prices and output the author shows that these bands mitigate the relationship between exogenous fundamentals and endogenous variables through their effects on expectations he also considers the effects of changing the width of the band and finds greater stabilization of endogenous variables with more narrow bands on exogenous fundamentals copyright 1990 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

target zones and realignments recent contributions emphasize that the presence of exchange rate target zones has important effects on the within band behavior of exchange rates when agents are forward looking the authors find that the implications of available models are inconsistent with european exchange rate data and they suggest that the frequent realignments occurring in the period they consider may be responsible for this they construct a model in which the likelihood of a realignment in the near future increases as the exchange rate approaches the limits of its fluctuation band and show that its implications are broadly consistent with the evidence copyright 1992 by american economic association

effects of innovation on employment a dynamic panel analysis abstract this paper estimates the effect of innovation on employment at the firm level our uniquely long innovation panel data set of german manufacturing firms covers more than 20 years and allows us to use various innovation measures we can distinguish between product and process innovations as well as between innovation input and innovation output measures using dynamic panel gmm system estimation we find positive effects of innovation on employment this is true for innovation input as well as for innovation output variables innovations show their positive effect on employment with a time lag and process innovations have higher effects than product innovations

on the evolution of market institutions the platform design paradox we study competition among market designers who create new trading platforms when boundedly rational traders learn to select among them we ask whether walrasian platforms leading to market clearing trading outcomes will dominate the market in the long run if several market designers compete we find that traders learn to select non market clearing platforms with prices systematically above the market clearing level provided at least one such platform is introduced by a market designer this in turn leads market designers to introduce non market clearing platforms hence platform competition induces non competitive market outcomes

the global economic crisis and the effect of immigrant workers on native born employment in europe the debate regarding the economic effects of employing immigrants has attracted renewed interest in european countries since the economic crisis we provide an approximation of the labour market effects of immigrant workers in four european countries during the global economic crisis after briefly analysing native and foreign born worker conditions for the most recent period our analysis focuses on the correlation between the stock of immigrant workers and the number of native labour market workers across several segments of the labour market using a simple model approach using eurostat and lfs labour force survey data we estimate a structural dynamic model using the generalised method of moments gmm to examine adjustment dynamics in the labour market and labour market segment and worker educational levels countries of origin and genders overall the empirical results suggest that immigrant labour force effects on native born worker employment rates have been persistent and but weak throughout the business cycle these effects are globally positive and immigrant origins do not appear to change the nature of their impact we offer some explanations for these findings related to dual labour markets and to differences in levels of substitution among native and immigrant workers

employment and technological innovation evidence from u k manufacturing firms this article uses british firm level panel data on actual innovative activity drawn from different statistical sources to identify the effect of technical change on jobs previous work tends to find positive associations of proxies for technical change and employment but such studies suffer from various statistical drawbacks in this study even when one controls for fixed effects dynamics and endogeneity innovations have a positive and significant effect on employment which persists over several years there seems to be little direct role for spillover effects from industry innovations or any role for industry wages or union power

big effects of small interventions the informational role of intervention in exchange rate policy abstract in this paper we demonstrate how an infintesimal unsterilized foreign exchange intervention may cause a very large discrete change in the exchange rate we analyze an example in which there is a target zone policy in place but the actual width of the target zone is not known by participants in the foreign exchange market in this case intervention both affects fundamentals and conveys information about policy the exchange rate jumps in response to intervention with the size of the jump related to the uncertainty about the true band width also in this model the relationship between the exchange rate and the fundamental depends upon both the history of the path of the exchange rate and whether or not intervention has occured

the greener the better job creation effects of environmentally friendly technological change this article investigates the link between environment related innovation and job creation at firm level employing italian data on 4507 manufacturing firms matched with patent records for the period 2001 2008 we test whether green innovation measured by the number of environment related patents has a positive effect on long run employment growth that is specific with respect to non environmental innovation results show a strong positive impact of green innovation on long run job creation substantially bigger than the effect of other innovations our findings are robust to a number of additional tests including controls for patents quality and cost differential between generic and green innovation and endogeneity

a model of exchange rate dynamics this model treats the exchange rate as an asset price that depends on expectations concerning exogenous real and monetary factors that will affect relative prices and absolute price levels in future periods changes in exchange rates reflect both expected changes in these exogenous factors and changes in expectations occasioned by new information the model explains the random component in exchange rate behavior the source of divergences from purchasing power parity the anticipatory response of exchange rates to future expected disturbances and the causes of exchange rate overshooting

environmental innovation and employment dynamics in different technology fields an analysis based on the german community innovation survey 2009 the employment effects of environmental technologies are in the focus of politicians but studies analyzing these effects for different environmental innovation fields are rare we use the 2009 wave of the community innovation survey cis allowing for such an analysis at the firm level our econometric analysis shows that innovative firms in general are characterized by a significantly more dynamic employment development especially the introduction of cleaner technologies as process innovations leads to a higher employment within the firm the theoretical background of this finding is that cost savings induced by this type of process innovation improve the competitiveness of firms this has positive effects on demand and thus also increases employment especially material and energy savings are positively correlated to employment because they help to increase the profitability and competitiveness of the firm on the other side air and water process innovations that are still dominated by end of pipe technologies have a negative impact on employment

swimming upstream trends in the gender wage differential in the 1980s using michigan panel study of income dynamics data for 1979 and 1988 we analyze how a falling gender wage gap occurred despite changes in wage structure unfavorable to low wage workers the decrease is traced to gender specific factors which more than counterbalanced changes in measured and unmeasured prices working against women supply shifts net of demand were unfavorable for women generally and hurt high skilled more than middle and low skilled women by analyzing wages we find support for the notion of a gender twist in supply and demand having its largest negative effect on high skilled women
