collateral damage refinancing constraints and regional recessions in the current structure of the u s residential mortgage market a decrease in property values may make it very difficult for homeowners to refinance their mortgages to take advantage of declining interest rates in this papr we show that this form of collateral constraint has greatly reduced refinancing in statds with depressed property markets we outline the interaction between regional recessions and refinancing constraints when adverse economic shocks cause property values in a region to decrease the damage to the collateral makes it difficult or impossible for some homeowners to obtain new mortgages in the recent period this has meant that homeowners in economically depressed regions have been unable to refinance their mortgages to take advantage of declining interest rates this inability to refinance has further economic impacts on the region through lowering the wealth and the discretionary income of local homeowners thereby deepening the regional recession while the possible link between regional declines in property values and refinancing activity has been understood for some time for example monsen 1992 the subject has received very little empirical attention we provide the first quantitative assessment of the impact of constraints arising from regional property market dynamics on refinancing activity to accomplish this we use a new data set on more than thirty five thousand individual mortgages the sample consists of all mortgages serviced by chemical bank with originations between june 1989 and may 1992

day of the week effects and asset returns the number of empirical studies using daily stock returns is rapidly increasing researchers generally assume that the distribution of stock returns is identical for all days of the week a convenient statistical assumption but not a necessary condition of market equilibrium nevertheless there are reasons to suspect that the distribution of returns may vary according to the day of the week the most obvious is the impact of weekends on monday s return since monday s return is calculated over three instead of one calender day the mean and variance may well be higher on monday compared with any other daily return perhaps three times as large previous research has examined the daily distribution of stock returns for a monday effect while fama 1965 does not compare daily mean returns he does report that monday s variance is about 20o greater than other daily returns with a traditional distributional assumption regarding the returns on a financial asset specifies that the expected returns are identical for all days of the week contrary to this plausible assumption this paper discovers that the expected returns on common stocks and treasury bills are not constant across days of the week the most notable evidence is for monday s returns where the mean is unusually low or even negative several explanations of the results are investigated but none proves satisfactory aside from documenting significant day of the week effects the implications of the results for tests of market efficiency are examined while market adjusted returns continue to exhibit day of the week effects these effects are no longer concentrated on monday during the last year we have had many conversations with our colleagues throughout the professions we are particularly thankful to the participants at sessions of the western and american finance associations where preliminary versions of this paper were presented special thanks are due to gene fama gailen hite jon ingersoll robert jarrow merton miller clifford smith and rex thompson the expert research assistance of frank rabinovitch and youngsup yun is gratefully acknowledged 1 the list of papers using daily stock returns is too long to name recent examples include charest 1978 dodd 1980 banz 1981 and reinganum 1981

wages profits and capital intensity evidence from matched worker firm data swedish data on workers matched with firms balance sheet reports are used to examine the relation between wages and firms ability to pay results indicate that experienced and highly educated workers are sorted into profitable firms wages are positively correlated with profits and the capital labor ratio after controlling for worker quality degree of effort supervision job characteristics local unemployment firms employment history and employer size lester s range of pay due to rent sharing is around 12 24 of the mean wage in sweden which is close to the estimates for the united states and united kingdom

economic and welfare impacts of climate change on developing countries the impact of global climate change on developing countries is analyzed using cge multimarket models for three archetype economies representing the poor cereal importing nations of africa asia and latin america the objective is to compare the effects of climate change on the macroeconomic performance sectoral resource allocation and household welfare across continents simulations help identify those underlying structural features of economies which are the primary determinants of differential impacts these are suggestive of policy instruments to countervail undesirable effects results show that all these countries will potentially suffer income and production losses however africa with its low substitution possibilities between imported and domestic foods fares worst in terms of income losses and the drop in consumption of low income households countervailing policies to mitigate negative effects should focus on integration in the international market and the production of food crops in africa and on the production of export crops in latin america and asia

estimating the implied cost of carbon in future scenarios using a cge model the case of colorado abstract using colorado as a case study we develop a state level computable general equilibrium cge model that reflects the roles of coal natural gas wind solar and hydroelectricity in supplying electricity we focus on the economic impact of implementing colorado s existing renewable portfolio standard updated in 2013 this requires that 25 of state generation come from qualifying renewable sources by 2020 we evaluate the policy under a variety of assumptions regarding wind integration costs and assumptions on the persistence of federal subsidies for wind specifically we estimate the implied price of carbon as the carbon price at which a state level policy would pass a state level cost benefit analysis taking account of estimated greenhouse gas emission reductions and ancillary benefits from corresponding reductions in criteria pollutants our findings suggest that without the production tax credit federal aid the state policy of mandating renewable power generation rps is costly to state actors with an implied cost of carbon of about 17 per ton of co2 with a 3 discount rate federal aid makes the decision between natural gas and wind nearly cost neutral for colorado

regional labor markets and the determinants of wage inequality from 1972 to 1990 the united states experienced the largest increase in wage inequality of any developed country the spread in log wages between the 90th and 10th percentiles of the male wage distribution increased by about 60 points and inequality increased within virtually every demographic or skill category of the labor force see chinhui juhn et al 1993 various explanations have been offered including changes in the relative demand for skill intensive goods international trade immigration of less skilled workers and increased labor force participation of women yet attempts to quantify the relative importance of these factors have not met with much success this leaves skill biased technical change as the residual claimant that rationalizes the data this paper uses regional differences in the evolution of wage inequality to provide new evidence on the determinants of relative wages using a model of factor demand in geographic markets i isolate contributions of i changing skill ratios in the labor force ii increased participation of women iii technical change and iv changes in the industrial composition of labor demand the data indicate that changing skill ratios and women s labor supply have affected the wages of low skilled men in the west the data indicate that increased immigration of less skilled hispanic and asian workers has adversely affected the wages of natives causing a greater increase in inequality there than in any other region of the country i modeling wage inequality in regional markets

the challenges of determining the employment effects of renewable energy abstract the benefits of promoting renewable energy are regularly claimed to be energy security climate change mitigation and job creation while the first two benefits are generally accepted the impact of renewable energy on employment is still disputed this paper presents a discussion of the various factors that influence the analysis of renewable energy and its impact on employment the advantages and disadvantages of input output methods and analysis methods are discussed as well as the issues surrounding the measurement of job creation a critical evaluation of the literature reveals factors that should be considered when completing a study about renewable energy and employment labour intensity of renewables cost increases and availability of investments counting job losses job quality and skills model assumptions and sources of information analytical studies using extensive surveys were found to be more appropriate for regional studies while input output methods were better suited to national and international studies

earnings news and small traders an intraday analysis abstract this study separates trading volume into buyer and seller initiated activities and examines the directional volume reaction in small and large trades to different types of earnings news good bad news triggers brief but intense buying selling in the large trades however a persistent period of unusually high buying activity is observed in the small trades irrespective of the news this anomalous proclivity of small traders to buy is robust across firm size trading volume and different earnings expectation models several explanations are discussed although the behavior does not seem fully explained by existing theories

assessing the impact of skill shortages on the productivity performance of high tech firms in northern ireland this article utilizes data from three separate skill related surveys of firms in the northern ireland it electronic engineering and mechanical engineering industries in order to assess the extent to which the performance of high tech firms are being constrained as a result of hard to fill and or unfilled vacancies whist it was found that the determinants of skill shortage varied somewhat depending upon the definitional approach adopted a high degree of correlation was found with regards to the impacts of skill shortages on firm level performance it was found that both hard to fill and unfilled vacancies had reduced output per worker levels by between 65 and 75 in affected firms however these impacts were only detecw after controlling for selection effects the evidence suggests that standard ols procedures can generate highly misleading results in studies of this nature

the impact of environmentally friendly innovations on value added while recent literature has focused on explaining the determinants of green innovations it is not well understood how such innovations affect performance to analyse the relationship between green innovation and performance new industry level panel data were exploited these include 12 oecd countries the whole manufacturing sector and a period of 30 years the results show that green inventions are u shape related to performance however the turning point is quite high and hence only relevant for a few industries this indicates that given the current level of green promotion market incentives alone are not sufficient to allow the green invention activities of industries to rise considerably to verify these results and to get a better understanding of the mechanisms in the green market we finally made several interviews with multinational firms that have a good understanding of what happens on the global market of green innovation

employment trends in the u s electricity sector 2008 2012 abstract between 2008 2012 electricity generated gwh from coal the longtime dominant fuel for electric power in the us declined 24 while electricity generated from natural gas wind and solar grew by 39 154 and 400 respectively these shifts had major effects on domestic employment in those sectors of the coal natural gas wind and solar industries involved in operations and maintenance o m activities for electricity generation using an economic input output model we estimate that the coal industry lost more than 49 000 jobs 12 nationally over the five year period while in the natural gas solar and wind industries employment increased by nearly 175 000 jobs 21 we also combine published ratios for jobs per unit of fuel production and per megawatt of power plant capacity with site specific data on fuel production and power plant retirements additions and capacity changes to estimate and map direct job changes at the county level the maps show that job increases in the natural gas solar and wind industries generally did not occur where there were significant job losses in the coal industry particularly in west virginia and kentucky

the hidden winners of renewable energy promotion insights into sector specific wage differentials abstract in light of germany s energy system transformation this paper examines differences in employment structures and wage differentials between renewable energy establishments and their sector peers to do so we have developed a novel data set by linking company level information from the german renewable energy federation with administrative establishment level data from the institute for employment research descriptive evidence shows significant differences in wages and several other characteristics between renewable energy establishments and their sector peers our estimates give evidence that human capital and other establishment level characteristics mostly explain the wage differential among manufacturers and energy providers however we find a persistent renewable energy wage premium of more than ten percent in construction installation activities and architectural engineering services we interpret this premium as a positive indirect effect of the promotion of renewable energies for the benefit of employees in renewable energy establishments within these two sectors

green jobs economic impacts of renewable energy in germany abstract the labor market implications of large investment into renewable energy re are analyzed in this text although a growing re industry can be observed in germany the overall effect of large increases of re based electricity and heat generating technologies on the german economy require a careful model based analysis the applied model panta rhei has been used among others to evaluate the german energy concept in 2010 it takes positive and negative impacts of re into account the paper shows the overall effects under different assumptions for fossil fuel prices domestic installations and international trade the results are sensitive to assumptions on the development of re world markets and german exports to these markets almost all of these scenarios exhibit positive net employment effects under medium assumptions net employment of re expansion will reach around 150 thousand in 2030 only with assumptions for german re exports below today s level net impacts are slightly negative gross employment will increase from 340 thousand in 2009 to between 500 and 600 thousand in 2030

differences in labor supply to monopsonistic firms and the gender pay gap an empirical analysis using linked employer employee data from germany this article investigates women s and men s labor supply to the firm within a semistructural approach based on a dynamic model of new monopsony using methods of survival analysis and a large linked employer employee data set for germany we find that labor supply elasticities are small 1 9 3 7 and that women s labor supply to the firm is less elastic than men s which is the reverse of gender differences in labor supply usually found at the level of the market our results imply that at least one third of the gender pay gap might be wage discrimination by profit maximizing monopsonistic employers

does unmeasured ability explain inter industry wage differentials this paper provides empirical assessments of the two leading explanations of measured inter industry wage differentials 1 true wage differentials exist across industries and 2 the measured differentials simply reflect unmeasured differences in workers productive abilities first we summarize the existing evidence on the unmeasured ability explanation second we construct a simple model which shows that if matching is important then endogenous job change decisions can create important self selection biases even in first differenced estimates of industry wage differentials third we analyze a sample that approximates the experiment of exogenous job loss we find that i the wage change experienced by a typical industry switcher closely resembles the difference in the relevant industry differentials estimated in a cross section and ii pre displacement industry affiliation plays an important role in post displacement wage determination

stock market crashes and the performance of circuit breakers empirical evidence this study examines the behavior of a small stock market with circuit breakers and with a one hour preauction order imbalance disclosure during the october 1987 crash the crash and its aftershocks lasted for a week and selling pressure was concentrated in higher beta larger capitalization and lower leverage firm stocks circuit breakers when implemented reduced the next day opening order imbalance and the initial price loss however they had no effect on the long run response some price overreaction and reversal phenomena also are documented

order imbalance liquidity and market returns traditionally volume has provided the link between trading activity and returns we focus on a hitherto unexplored but intuitive measure of trading activity the aggregate daily order imbalance on the new york stock exchange signed order imbalances increase decrease following market declines rises which reveals that investors are contrarians on aggregate order imbalances in either direction either excess buy or sell orders reduce liquidity market wide returns are strongly affected by contemporaneous and lagged order imbalances market wide returns reverse themselves after high negative imbalance large negative return days the magnitude of this reversal is partially predictable from the level of the imbalance and return even after controlling for aggregate market volume and liquidity market returns are affected by order imbalance

why do cities pay more an empirical examination of some competing theories of the urban wage premium abstract ols regression identifies a 19 percent wage advantage for workers in large urban areas fixed effects estimation suggests that two thirds of this premium can be explained by cities attracting workers of higher unmeasured skills and ability the remaining wage premium is shown to consist of both level and growth elements the wage level effect is consistent with a productivity advantage for firms located in cities the wage growth effect is shown to relate in part to a cumulative advantage in the returns to job mobility for urban workers this last finding highlights the importance of coordination in urban labor markets

do newly founded firms pay lower wages first evidence from germany using a linked employer employee data set for germany this paper analyses wage setting in a cohort of newly founded and other establishments from 1997 to 2001 while theory provides alternative explanations for higher or lower wages in newly founded firms we show empirically that start ups tend to pay lower wages ceteris paribus on average wages in newly founded establishments are 8 lower than in similar incumbent firms this negative wage differential is substantially smaller in eastern than in western germany the wage differ ential is shown to decline over time as the newly founded firms become more mature

renewable energy policies and private sector investment evidence from financial microdata this paper analyses the effect of government policies and other determinants on private finance investment in renewable energy a unique dataset of financial transactions for renewable energy projects is constructed using the bloomberg new energy finance database the dataset covers 87 countries six renewable energy sectors wind solar biomass small hydropower marine and geothermal and the 2000 2011 time span in a first set of models undertaken at the level of the financial deal we find that in contrast to quota based schemes price based support schemes are positively correlated with private finance contributions this result holds for complementary analyses undertaken at the level of the project however for those projects in which public finance complements private finance co financed projects neither quota based measures nor price based support schemes have a significant effect on private finance flows

new market power models and sex differences in pay in the context of certain models it is possible to infer the elasticity of labor supply to the firm from the elasticity of the quit rate with respect to the wage we use this strategy to estimate the elasticity of labor supply for men and women workers at a chain of grocery stores identifying separation elasticities from differences in wages and separation rates across different job titles within the firm we estimate that women have lower elasticities so a robinson style monopsony model can explain reasonably well the lower relative pay of women in the retail grocery industry
