does the gap in family friendly policies drive the family gap a segregation of the labour market into a family friendly and a non family friendly sector has the effect that women self select into the sectors depending on institutional constraints preferences for family friendly working conditions and expected wage differences we find that neglecting the sector dimension tends to understate the effect of birth related interruptions in both sectors the combined effect of a large depreciation effect and no recovery means that females in the non family friendly sector e g private sector are punished severely after childbirth in the family friendly sector e g public sector we find complete catch up

complementarity and external linkages the strategies of the large firms in biotechnology in biotechnology large firms enter into different kinds of linkages with universities and small medium sized research intensive firms we test the hypothesis that the strategies of external linkage of the large firms with other parties are complementary to one another we show that if any two strategies are complementary i e undertaking more of one strategy raises the marginal value of the other then they are positively correlated using data for a sample large us european and japanese chemical and pharmaceutical producers we find that the strategies above are positively correlated even after controlling for firm specific characteristics

understanding the family gap in pay for women with children as the gender gap in pay between women and men has been narrowing the family gap in pay between mothers and nonmothers has been widening one reason may be the institutional structure in the united states which has emphasized equal pay and opportunity policies but not family policies in contrast to other countries that have implemented both the authors now have evidence on the links between one such family policy and women s pay recent research suggests that maternity leave coverage by raising women s retention after childbirth also raises women s levels of work experience job tenure and pay

marriage motherhood and wages we explore several problems in drawing causal inferences from cross sectional relationships between marriage motherhood and wages we find that heterogeneity leads to biased estimates of the direct effects of marriage and motherhood on wages i e effects net of experience and tenure first difference estimates reveal no direct effect of marriage or motherhood on women s wages we also find statistical evidence that experience and tenure may be endogenous variables in wage equations instrumental variables estimates suggest that both ordinary least squares cross sectional and first difference estimates understate the direct negative effect of children on wages

liberalizing foreign investments by pension funds positive and normative aspects abstract the paper evaluates the economics of foreign investment regulation for pension funds with a focus on developing countries where fully funded pension systems are being started de novo the analysis proceeds in three steps first it is argued that the benefits of global portfolio diversification apply particularly to developing country pension assets because the volatility of asset returns is high while the risk tolerance of pensioners is low second restrictions of foreign investmetn by domestic pension funds can hardly be justified on ground of financial development arguments the paper presents crosscountry evidence which shows little support for the claim that the accumulation of pension assets would provide strong externalities for financial development moreover the home bias generally observed in pension fund investment should translate into sufficient potential demand for domestic financial assets as to deepen markets and develop the institutional infrastructure third a case for initial localization requirements however can be derived from the fiscal costs of moving from unfunded to fully funded pension systems if fiscal illustion and domestic tax collection costs are important

in and out of the labour market long term income consequences of child related interruptions to women s paid work why do canadian mothers have lower incomes than women who have never had children microdata from the 1995 gss allow examination of two hypotheses 1 mothers have spent more time out of the labour force thus acquiring less human capital 2 higher levels of unpaid work lead to fatigue and or scheduling difficulties measuring work history does little to account for the family gap the estimated child penalty is reduced by allowing for human capital depreciation and controlling for unpaid work hours but the two hypotheses together cannot entirely explain the gap jel classification j0 j3 entrees et sorties marche du travail et consequences a long terme des interruptions dans l experience sur le marche du travail a cause des enfants ce memoire se demande pourquoi les femmes canadiennes qui ont eu des enfants ont des revenus plus bas que ceux des femmes qui n en ont pas eus les microdonnees de l enquete sociale generale de 1995 de statistiques canada permettent d examiner deux hypotheses 1 les meres ont passe plus de temps en dehors de la main d oeuvre active et donc ont accumule moins de capital humain ou 2 des niveaux plus eleves de travail non remunere peuvent entrainer fatigue ou difficultes d organisation du temps des efforts pour construire une meilleure image de l experience de travail des femmes ne permettent pas d expliquer cet ecart familial meme si la possibilite qu il y ait depreciation du capital humain reduit la penalisation attachee au fait d avoir un enfant en particulier si l interruption dans l experience sur le marche du travail est suivie d un changement d emploi le nombre hebdomadaire d heures de travail non paye est relie negativement aux revenus et si l on normalise pour tenir compte des heures de travail non paye cela reduit la penalisation attachee au fait d avoir un enfant cependant les deux hypotheses combinees ne suffisent pas pour expliquer l ecart

repossession and the democratization of credit we exploit a 2004 credit reform in brazil that simplified the sale of repossessed cars used as collateral for auto loans we show that the reform expanded credit to riskier self employed borrowers who purchased newer more expensive cars the legal change has led to larger loans with lower spreads and longer maturities although the credit reform improved riskier borrowers access to credit it also led to increased incidences of delinquency and default our results shed light on the consequences of a credit reform and highlight the crucial role that collateral and repossession play in the liberalization and democratization of credit

is relationship lending special evidence from credit file data in germany the german financial market is often characterized as a bank based system with strong bank customer relationships the corresponding notion of a housebank is closely related to the theoretical idea of relationship lending it is the objective of this paper to provide a direct comparison between housebanks and normal banks as to their credit policy therefore we analyze a new data set representing a random sample of borrowers drawn from the credit portfolios of five leading german banks over a period of five years we use credit file data rather than industry survey data and thus focus the analysis on information that is directly related to actual credit decisions in particular we use bank internal borrower rating data to evaluate borrower quality and the bank s own assessment of its housebank status to control for information intensive relationships the major results of our study support the view that housebanks are able to establish a distinct behavioral pattern consistent with the idea of long term commitment we find that housebanks do provide liquidity insurance in situations of unexpected deterioration of borrower ratings with respect to loan pricing we find no evidence for intra or intertemporal price differentiation related to housebanking

the family gap for young women in the united states and britain can maternity leave make a difference in the united states and britain there is a family gap between the wages of mothers and other women differential returns to marital and parental status explain 40 50 of the gender gap another 30 40 is explained by women s lower levels of work experience and lower returns to experience taking advantage of quasi experiments in job protected maternity leave in the united states and britain this article finds that women who had leave coverage and returned to work after childbirth received a wage premium that offset the negative wage effects of children

the effect of sibling sex composition on women s education and earnings this paper documents the impact of siblings on the education of men and women born in the united states between 1920 and 1965 we examine the effect of the number and sex composition of a boy or girl s siblings on that child s educational attainment we find that throughout the century women s educational choices have been systematically affected by the sex composition of her siblings and that men s choices have not women raised only with brothers have received on average significantly more education than women raised with any sisters controlling for household size since sibling sex composition affects women s educational attainment and plausibly may be unrelated to other determinants of earnings it may provide a useful instrument for education in earnings functions for women our results suggest that standard estimates significantly underestimate the return to schooling for women

efficiency in hierarchies implementing the first best solution by sequential actions a model of a firm with one principal and two agents is considered the actions of the agents are not observed by the principal hence there is moral hazard it is shown that when the agents act sequentially that is agent 2 takes his action conditional upon agent i s choicethe first best actions can be implemented by a suitable choice of the incentive schemes given to the two agents the result relies both on the sequential nature of the game and on the particular specification of the effect that the agents actions have on output several extensions and applications of the framework are suggested in particular it is shown that the analysis generalizes to the case of more than two agents

the costs of motherhood an analysis using matching estimators we estimate the effect of motherhood on wages using matching we distinguish between net and direct effects the net effect includes the total wage costs whereas the direct represents the causal effect since covariates are likely affected by motherhood the latter effect is not immediately uncovered we therefore implement two strategies first we confine the analysis to consider sector specific treatment effects second we impose additive separability on the outcome equation we find negative net effects that vary little with sector the direct effect is small and negative in the public sector and insignificant in the private sector copyright 2006 john wiley sons ltd

creditor concentration an empirical investigation most of the literature on multiple banking assumes equal financing shares however unequal asymmetric or concentrated bank borrowing is widespread and creditor concentration is only weakly correlated with the number of bank relationships this paper therefore investigates the determinants of creditor concentration for german firms using a comprehensive firm bank level dataset for the time period between 1993 and 2003 we document that corporate borrowing from banks is very often concentrated even for the largest firms in our sample leveraged firms and firms with more redeployable assets concentrate their borrowing from banks as are firms dealing with a relationship lender that is profitable that has lower monitoring costs or that operates in a concentrated regional lending market

financial development and economic growth abstract this paper examines the empirical relationship between long run growth and financial development proxied by the ratio between bank credit to the private sector and gdp we find that this proxy is positively correlated with growth in a large cross country sample but its impact changes across countries and is negative in a panel data for latin america we argue that the latter findings is the result of financial liberalization in a poor regulatory environment our findings also show that the main channel of transmission from financial development to growth is the efficiency rather than the volume of investment

capital controls collection costs and domestic public debt abstract the implications of a large public debt for the implementation of capital controls for an economy where tax revenue collection is costly are examined conditions are analyzed under which policymakers will resort to capital controls to reduce the cost of recycling domestic public debt the linkages between a costly tax collection mechanism capital controls and domestic government debt are explored in terms of a two period model of optimal taxation numerical simulations are provided to illustrate how capital controls are linked to different domestic public debt levels and to different degrees of efficiency in tax revenue collection

credit and efficiency in centralized and decentralized economies we study a credit model where because of adverse selection unprofitable projects may nevertheless be financed indeed they may continue to be financed even when shown to be low quality if sunk costs have already been incurred we show that credit decentralization offers a way for creditors to commit not to refinance such projects thereby discouraging entrepreneurs from undertaking them initially thus decentralization provides financial discipline nevertheless we argue that it puts too high a premium on short term returns the model seems pertinent to two issues soft budget constraint problems in centralized economies and differences between anglo saxon and german japanese financing practices

optimal debt structure and the number of creditors within an optimal contracting framework we analyze the optimal number of creditors a company borrows from we also analyze the optimal allocation of security interests among creditors and intercreditor voting rules that govern renegotiation of debt contracts the key to our analysis is the idea that these aspects of the debt structure affect the outcome of debt renegotiation following a default debt structures that lead to inefficient renegotiation are beneficial in that they deter default but they are also costly if default is beyond a manager s control the optimal debt structure balances these effects we characterize how the optimal debt structure depends on firm characteristics such as its technology its credit rating and the market for its assets

financial contracting and leverage induced over and under investment incentives this paper investigates the effects of seniority rules and restrictive dividend convenants on the over and under investment incentives associated with risky debt we show that increasing seniority of new debt decreases the incidence of under investment but increases over investment and vice versa under symmetric information the optimal seniority rule is to give new debtholders first claim on a new project without recourse to existing assets i e project financing under asymmetric information the optimal debt contract requires equating the expected return to new debtholders in the default state to the new project s cash flow in the same rate if this is not possible the optimal seniority rule calls for strict subordination of new debt if the expected cash flow in default is small and full seniority if it is large with regard to dividend convenants we show that their effect depends on whether or not dividend payments are conditioned on future investments when they are unconditioned allowing more dividends increases the under investment incentive in contrast conditional dividends decrease the underinvestment incentive and increase the over investment incentive

why do tougher caseworkers increase employment the role of programme assignment as a causal mechanism abstract previous research found that less accommodating caseworkers are more successful in placing unemployed workers into employment this paper explores the causal mechanisms behind this result using semi parametric mediation analysis analyzing rich linked job seeker caseworker data for switzerland we find that the positive employment effects of less accommodating caseworkers are not driven by a particularly effective mix of labor market programs but rather by other dimensions of the counseling process possibly including threats of sanctions and pressure to accept jobs

wealth constraints and option contracts in models with sequential investments summary the paper investigates a model where two parties a and b invest sequentially in a joint project an asset investments and the asset value are nonverifiable and a is wealth constrained so that an initial outlay must be financed by either agent b insider financing or an external investor a bank c outsider financing we show that an option contract in combination with a loan arrangement facilitates first best investments and any arbitrary distribution of surplus if renegotiation is infeasible moreover the optimal strike price of the option is shown to dier across financing modes if renegotiation is admitted we identify conditions under which the first best can still be attained then either b financing or c financing may be strictly preferable and a combination of insider and outsider financing may be strictly optimal

a theory of debt and equity diversity of securities and manager shareholder congruence this paper shows how the optimal financial structure of a firm complements incentive schemes to discipline managers and how the securities return streams determine the claim holders incentives to intervene in management the theory rationalizes 1 the multipucity of securities 2 the observed correlation between return streams and control rights of securities and 3 the partial congruence between managerial and equity holder preferences over policy choices and monetary rewards as well as the low level of interference of equity in management the theory also offers new prospects for a reappraisal of the earlier corporate finance literature

debt and seniority an analysis of the role of hard claims in constraining management we argue that long term debt has a role in controlling management s ability to finance future investments a company with high widely held debt will find it hard to raise capital since new security holders will have low priority relative to existing creditors conversely for a company with low debt we show there is an optimal debt equity ratio and mix of senior and junior debt if management undertakes unprofitable as well as profitable investments we derive conditions under which equity and a single class of senior long term debt work as well as more complex contracts for controlling investment behavior
