statistical models of consumer behavior with heterogeneous values and constraints in a market with heterogeneous individuals the fact that a particular group of individuals are the consumers of a particular product already indicates that there exist systematic differences between them and the average person simple tools from statistical theory are used here to analyze the implications of consumer diversity it is argued that an increase in consumer diversity will increase the gains from trade and that there is a shadow price of heterogeneity associated with product quality throughout the discussion the significance of consumer self selection and the distinction between average and marginal will be emphasized

compensating differentials and self selection an application to lawyers this paper models individual choice between two types of jobs as dependent on the difference in potential earnings and on preferences for nonpecuniary the model leads to simultaneous estimation of earnings and job choice functions in a manner that takes account of self selection of individuals into the sector of highest utility an application to lawyers choosing between private and public interest law casts doubt on the notion that public interest lawyers are accepting substantially lower earnings by virtue of their choice an impression derived from estimation of earnings functions without accounting for self selection the estimation technique also takes proper account of the choice based nature of the sample which appears to be important

clustering of initial public offerings information revelation and underpricing abstract by providing an analysis of sequential going public decisions the paper outlines conditions under which hot issue markets arise i e under which the likelihood of a second initial public offering increases after a first firm has gone public two effects can trigger the rise of hot issue markets in a setting with asymmetric and costly information about both firm quality and industry prospects the risk averse entrepreneur can be subject to risk induced selling pressure because of uncertain industry prospects conveyed by a first ipo in the industry also investors can free ride on the industry news and increase their valuation for a second firm by abstaining from further costly information production finally the model offers an explanation for the empirical finding that hot issue markets exhibit a higher degree of underpricing than cold issue markets

valuing alternative work arrangements abstract we employ a discrete choice experiment in the employment process for a national call center to estimate the willingness to pay distribution for alternative work arrangements relative to tr

the berlin stock exchange in imperial germany a market for new technology analysing 474 cases of firms going public in the german capital between 1892 and 1913 we show that innovative firms could rely on the berlin stock market as a source of financing the data also reveal that initial public offerings ipo of innovative firms were characterized by particularly low underpricing comparatively high first trading prices and no long run underperformance we interpret these empirical results as evidence for the surprising fact that contemporary investors had rational expectations

promotions and incentives in nonprofit and for profit organizations using data from the 1992 95 multi city study of urban inequality an employer survey the authors document a new empirical finding that workers are less likely to receive promotions in nonprofit organizations than in for profit firms the study also uncovers evidence that wage increases associated with promotion were of comparable magnitudes in the two sectors as was the potential for within job wage growth nonprofits were less likely than for profits to base promotions on job performance or merit nonprofits were less likely to use output contingent incentive contracts to motivate workers and the observed difference in promotion rates between the nonprofit and for profit sectors was more pronounced for high skilled than for low skilled workers the authors also propose a theory that potentially explains the broad pattern of evidence they uncover based on the idea that nonprofit workers are more intrinsically motivated attracted to their work for reasons transcending material compensation than are f

search and nonwage job characteristics this paper quantifies the importance of nonwage job characteristics to workers by estimating a structural on the job search model the model generalizes the standard search framework by allowing workers to search for jobs based on both wages and job specific nonwage utility flows within the structure of the search model data on accepted wages and wage changes at job transitions identify the importance of nonwage utility through revealed preference the estimates reveal that utility from nonwage job characteristics plays an important role in determining job mobility the value of jobs to workers and the gains from job search

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

the pervasive absence of compensating differentials we study the relation between individual preferences for job amenities e g type of work job security and compensating wage differentials in cross section to this end we estimate a partial equilibrium job search model on panel data from eight european countries there are five non wage job characteristics and two sources of job to job mobility on the job search and reallocation shocks we also allow for two types of unobserved heterogeneity we find strong preferences for amenities especially job security yet these preferences do not translate into significant wage differentials in cross section counterfactual experiments show that one would need extremely low levels of search frictions for compensating differentials to arise lastly a similar exercise on the distribution of job change outcomes reveals the role of constrained job to job mobility in the absence of compensating wage differentials copyright 2009 john wiley sons ltd

strategic trading behavior and price distortion in a manipulated market anatomy of a squeeze abstract this paper investigates an attempted delivery squeeze in a bond futures contract traded in london using cash and futures trades of dealers and customers we analyze their strategic trading behavior price distortion and learning in a market manipulation setting we argue that marked differences in settlement failure penalties in the cash and futures markets create conditions that favor squeezes we recommend that regulators require special flagging of forward term repurchase agreements on the key deliverables that span futures contract maturity dates and that exchanges mark to market their contract specifications more frequently or consider a cash settled contract on a basket of bonds

modeling charitable contributions of time and money abstract public goods theory predicts that government spending on charity can perfectly crowd out charitable contributions empirical research has found little support for the perfect crowd out hypothesis however the empirical work only measures part of a contributor s total contribution gifts of money contributors also volunteer labor this article extends the public goods model to the case in which individuals contribute both time and money to a charity that in turn produces a public good the model suggests that charitable contributions of time and money are perfectly substitutable in equilibrium this result offers new interpretations for existing empirical observations and suggests a new test of the crowd out hypothesis the implications of the model are empirically tested using a national survey of charitable activity

pricing initial public offerings further evidence from germany abstract in a recent article in this review wasserfallen and wittleder pricing initial public offerings evidence from germany european economic review 38 1505 1517 1994 ww provide evidence of the well known underpricing phenomenon for 92 german ipos coming to market in 1961 1987 using a larger sample of 189 firms from 1970 1993 this paper i reassesses the evidence on underpricing in germany after choosing a different risk proxy to avoid potential endogeneity problems and ii provides evidence of long run ipo performance a number of new results emerge stock market returns the macroeconomic climate insider retention rates and inverse offer size all affect underpricing positively over longer horizons german ipos are poor investments losing more than twelve percent over their first three years of trading relative to the market exclusive of the initial underpricing return negative performance is heavily concentrated after the end of ww s sampling period in the post 1987 cohort

pricing initial public offerings evidence on the pricing of initial public offerings is presented for germany a data set of 92 going publics over the years 1961 1987 is analyzed on average the initial return from the offer price to the first day of trading adjusted for market movements is more than 15 o tests of several hypotheses indicate that underpricing is related to ex ante uncertainty about the value of the shares

a modified switching regression model for earnings differentials between the public and private using dutch 1986 data the wage differentials between public sector and private sector workers are investigated by employing a variation of the switching regression model this model imposes fewer identification restrictions on the parameters of the model than the standard switching regression model the estimation results show that some categories of public sector workers earn substantially less than private sector workers copyright 1993 by mit press

underwriter price support and the ipo underpricing puzzle abstract this paper reassesses the apparent systematic underpricing of initial public offerings ipos investigation of the distribution of initial returns following ipos shows that positive mean initial returns may reflect the existence of a partially unobserved left negative tail moreover most ipos with zero one day returns subsequently fall in price suggesting that underwriter price support may account for the skewed distribution and hence the phenomenon of positive average initial ipo returns even if offering prices are set at expected market value this paper thus challenges the presumption underlying previous research that positive average initial ipo returns result primarily from deliberate underpricing

job mobility and the market for lawyers this paper studies the life cycle career choices of law school graduates using unique data from the university of michigan law school the model assumes that these graduates act according to the optimal solution of a dynamic optimization problem in which they sequentially choose among five employment sectors the employment sectors are differentiated by pecuniary and nonpecuniary returns promotion and dismissal probabilities and the extent of transferability of human capital the estimation of the model reveals a self selection mechanism based on unobserved heterogeneity in abilities and expected future returns which plays a critical role in reproducing the sector specific nonmonotonic separation hazards observed in the data the underlying self selection mechanism also has implications for policy interventions in the market for lawyers such as loan forgiveness programs

history is repeating itself get ready for a long dry spell the recent disappearance of a five year maturity gap from the set of bonds deliverable to the chicago board of trade treasury bond futures has resulted in a distinctive configuration whereby a single t bond will have the shortest remaining maturity in the delivery basket of bonds for a five year period this situation would be inconsequential were three other conditions not simultaneously present ensuring that this single bond will probably be the cheapest to deliver bond over the next five years we show that a similar alignment of conditions happened in 1994 1999 during the long dry spell of the 11 we recall the detrimental repercussions of that dry spell on the bond markets and suggest possible steps to remedy the current situation

public and private sector wages in the netherlands there is much debate in the netherlands about underpayment of public sector workers relative to private sector workers in this paper we analyze the wage structures in both sectors using an endogenous switching regression model unlike previous dutch studies we find that the earnings prospects of public sector workers are better in the public sector than in the private sector for private sector workers we find the exact opposite their earnings prospects are better in the private sector moreover the allocation over sectors points to comparative advantages

how much do farmers value their independence a farmer s decision to contract or produce independently depends on the distribution of income and the nonpecuniary attributes associated with both business arrangements the benefits to growers from contracting such as risk reduction may be overestimated if the nonpecuniary benefits enjoyed by independent producers such as the right to make management decisions and own the commodity produced are not accounted for this study uses data from a u s national survey of hog producers to estimate 1 the difference in expected net returns between contracting and independent production 2 the premium a representative farmer would pay for the risk reduction provided by a contract and 3 the premium a farmer would pay for the nonpecuniary benefits associated with independent production results indicate that growers have a strong preference for autonomy with moderately risk averse growers being willing to pay more for the attributes of independent production than they would for the risk reducing benefits of a contract

ranking firms using revealed preference this article estimates workers preferences for firms by studying the structure of employer to employer transitions in u s administrative data the article uses a tool from numerical linear algebra to measure the central tendency of worker flows which is closely related to the ranking of firms revealed by workers choices there is evidence for compensating differentials when workers systematically move to lower paying firms in a way that cannot be accounted for by layoffs or differences in recruiting intensity the estimates suggest that compensating differentials account for over half of the firm component of the variance of earnings

a model of the demand for investment banking advising and distribution services for new issues this paper presents a theory of the demand for investment banking advising and distribution services for the case in which the investment banker is better informed about the capital market than is the issuer and the issuer cannot observe the distribution effort expended by the banker the optimal contract under which the offer price decision is delegated to the better informed banker in order to deal with the adverse selection and moral hazard problems resulting from the informational asymmetry and the observability problem is characterized the model demonstrates a positive demand for investment banking advising and distribution services and provides an explanation of the underpricing of new issues an investment banker performs three functions which may be of value to an issuer of new securities underwriting advising and distribution this paper presents a theory of the demand for investment banking advising and distribution services based on an informational asymmetry between an issuer of new securities and an investment banker ultimately a theory of the organization of the financial intermediary industry is required that would predict which firms would use which types of financial intermediaries for which purposes and which firms would raise capital without engaging the services of a financial intermediary only a limited set of such predictions are developed here in the context of a model of a fixedprice offering under a negotiated contract in which the investment banker is

managerial talent motivation and self selection into public management the quality of public management is a recurrent concern in many countries calls to attract the economy s best and brightest managers to the public sector abound this paper studies self selection into managerial and non managerial positions in the public and private sector using a model of a perfectly competitive economy where people differ in managerial ability and in public service motivation we find that if demand for public sector output is not too high the equilibrium return to managerial ability is always highest in the private sector as a result relatively many of the more able managers self select into the private sector since this outcome is efficient our analysis implies that attracting a more able managerial workforce to the public sector by increasing remuneration to private sector levels is not cost efficient

nonprofit and proprietary sector behavior wage differentials among lawyers this paper focuses on earnings differentials in the for profit and private nonprofit sectors with specific reference to lawyers an earnings equation for private lawyers is estimated and is used to predict what the nonprofit sector public interest lawyers could earn in the private sector the finding is that the public interest lawyers are paid substantially less that they know this and that the financial sacrifice is permanent next a job choice equation is estimated which suggests that those lawyers who choose public interest work have different preferences from those who choose private law practices the difference may help to account for the willingness of the public interest lawyers to accept lower monetary rewards further research is needed to determine whether the differences found for lawyers in the two sectors are also found in other industries and whether such differences are found only at the level of management or at lower levels the goal is improved understanding of behavioral diff

the costs of going public abstract this paper presents evidence regarding the two quantifiable components of the costs of going public direct expenses and underpricing together these costs average 21 22 of the realized market value of the securities issued for firm commitment offers and 31 87 for best efforts offers for a given size offer the direct expenses are of the same order of magnitude for both contract types but the underpricing is greater for best efforts offers an explanation of why some firms choose to use best efforts offers in spite of their apparent higher total costs is given

substitution between wage and nonwage benefits you gotta be kidding ollie you re just robbing yourself schuylkill mutual offers a terrific deal on keogh and we could plug you in in fact we advise plugging you in on the corporate end so not a nickel comes out of your personal pocket it comes out of the corporate pocket and there s that much less for uncle to tax these poor saps carrying their own premiums with no company input are living in the dark ages there s nothing shady about rigging it this way we re just using the laws the government has put there they want people to take advantage it all works to up the gross national product you know what i mean by keogh don t you you re looking kind of blank john updike p 296

the central government private sector wage differential since ehrenberg and schwarz 1986 there has been a plethora of articles investigating the relationship between public and private sector wages this article examines part of this post 1986 literature by reviewing articles that examine central government private sector wage differentials in sum most articles find that there is a premium paid to central government workers although the premium has declined in recent years in developing countries however the differential is usually negative women and minorities tend to do better in the public sector relative to their private sector counterparts the evidence on union premiums between sectors is mixed although the premium tends to be higher in the private sector however public sector union workers do not do much better than private sector union members the magnitude of all of the wage differentials discussed are sensitive to the estimation technique and data source used the most common explanation for the public sector wage premium is economic rent accruing to government workers although the public sector wage determination literature suggests that the differential is due to returns to political and vote producing activities not relevant in the private sector
