the life duration of small firms born within a start up programme evidence from italy del monte a and scalera d 2001 the life duration of small firms born within a start up programme evidence from italy reg studies 35 11 21 we argue in this paper that the success of a subsidy programme should not be evaluated by comparing the survival rates of subsidized and non subsidized firms since the purpose of subsidies is to offset a gap with firms that do not need subsidies secondly we seek to identify the main factors avecting the death probability of small firms born within a start up programme to this end we conduct an empirical investigation of the firms supported by law 44 in italy between 1988 and 1997 finding that the amount of capital invested has a negative impact on life duration while the capital labour ratio and the amount of subsidy exert a positive influuence the main result is the unusual negative relationship between size and survival which we interpret in terms of the bias induced by subsidies in favour of larger and riskier firms del monte a et scalera d 200

rational household labor supply traditionally household behavior is derived from the maximization of a unique utility function in this paper we propose an alternative approach in which the household is modeled as a two member collectivity taking pareto efficient decisions the consequences of this assumption are analyzed in a three good model in which only total consumption and each member s labor supply are observable if the agents are assumed egoistic i e they are only concerned with their own leisure and consumption it is possible to derive falsifiable conditions upon household labor supplies from both a parametric and nonparametric viewpoint if alternatively agents are altruistic restrictions obtain in the nonparametric context useful interpretation stems from the comparison with the characterization of aggregate demand for a private good economy

socially responsible investing an investor perspective given the growing importance of socially responsible investing sri it is surprising that there is no consensus of what the term sri means to an investor further most studies of this question rely solely on the views of investors who already invest in sri funds our study surveys a unique pool of approximately 5 000 investors that contains both investors who have used sri criteria in investment decisions and those who have not and involves a broad array of criteria associated with sr investing our findings offer new insight into the sri debate for both sets of investors environmental and sustainability issues dominate as the major category associated with sr investing we find strong agreement in the ranking of the relative importance of various sri factors despite differences between these two groups in their opinion of their overall importance we also find that investors prefer to consider the sri question in more holistic terms rather than using the exclusionary format favored by most sri funds investors seem to prefer to reward firms who display overall positive social behavior rather than to exclude firms on the basis of certain products or practices these findings can help providers of sr investment vehicles to improve the sri products that they offer to the general investor thus both encouraging the initial adoption of sr criteria by investors and increasing overall investment in sr choices

collective female labour supply theory and application this article deals with female labour supply in the collective framework it studies married couples and starting from the empirical observation that the husband s labour supply is generally fixed at full time it shows that in this case structural elements of the decision process such as individual preferences or the rule that determines the intra household distribution of welfare can be identified if household demand for at least one commodity together with the wife s labour supply is observed these theoretical considerations are followed by an application using french data

marriage and consumption insurance what s love got to do with it when markets are incomplete individuals may choose to marry to diversify their labor income risk love however can complicate the picture if love is fleeting or the resolution of agents income uncertainty occurs predominantly later in life then marriages with good economic matches last longer in contrast if love is persistent and the resolution of uncertainty to agents income occurs early then marriages with good economic matches are more likely to be caught short with too little love to save a marriage consequently once married the partners will be more likely to divorce evidence is provided to distinguish between these alternative scenarios

diversification patterns and survival as firms mature we focus on the relationship between age and diversification patterns of german machine tool manufacturers in the post war era we distinguish between minor diversification adding a new product variation within a familiar submarket and major diversification expanding the product portfolio into new submarkets our analysis reveals four main insights first we observe that firms have lower diversification rates as they grow older and that eventually diversification rates even turn negative for old firms on average where negative diversification corresponds to exit from certain product lines second we find that product portfolios of larger firms tend to be more diversified third with respect to consecutive diversification activities quantile autoregression plots show that firms experiencing diversification in one period are unlikely to repeat this behavior in the following year fourth survival estimations reveal that diversification activities reduce the risk of exit in general and to a varying degree at different ages these results are interpreted using penrosean growth theory

are there non linearities between sme growth and its determinants a quantile approach this article uses quantile regressions to study the relationship between the growth of portuguese small and medium enterprises smes and its determinants to control a sample selection bias we use a two step estimation in the first stage we verified that past growth size age rd ii debt and rd iii age is a restrictive factor of portuguese sme growth only when there is an increase in size and iv cash flow although a determinant promoting portuguese sme growth regardless of the level of growth takes on greater importance when there is a reduction in size copyright 2010 the author 2010 published by oxford university press on behalf of associazione icc all rights reserved oxford university press

investment with a conscience examining the impact of pro social attitudes and perceived financial performance on socially responsible investment behavior this article addresses the growing industry of retail socially responsible investment sri profiled mutual funds very few previous studies have examined the final consumer of sri profiled mutual funds therefore the purpose of this study was to in an exploratory manner examine the impact of a number of pro social financial performance and socio demographic variables on sri behavior in order to explain why investors choose to invest different proportions of their investment portfolio in sri profiled funds an ordinal logistic regression analysis on 528 private investors revealed that two of the three pro social variables had a positive impact on how much the consumer invested in sri profiled funds moreover there was proof of a non altruistic motive for investing in sri as consumers who perceive that financial return of sri is equal or better than regular mutual funds invested a greater proportion of their portfolio in sri profiled mutual funds furthermore the results showed that women and better educated investors were more likely to invest a greater proportion of their investment portfolio in sri overall the findings indicate that both financial perceptions and pro social attitudes are connected to consumer investment in sri

marriage and divorce changes and their driving forces the family is not a static institution in recent decades marriage rates have fallen divorce rates have risen and the defining characteristics of marriage have changed the economic approach to the family seeks to explain these trends by reference to models that can also explain how and why families form gary becker s 1981 treatise on the family proposed a theory based on production complementarities in which husband and wife specialize in the market and domestic spheres respectively production complementarities also arise in the production and rearing of one s own children however production complementarities at least as initially described are decreasingly central to modern family life increased longevity and declining fertility mean that most of one s adult life is spent without one s own children in the household also the rise in marital formation at older ages including remarriage means that many families form with no intention of producing children moreover increases in female labor force participation suggest that household specialization has either declined or at least taken on a different meaning these changes have come about as what is produced in the home has been dramatically altered both by the emergence of labor saving technology in the home and by the development of service industries that allow much of what was once provided by specialized homemakers to be purchased in the market the availabil

do you have time to take a walk together private and joint time within the household we develop a theoretical model for the intra household allocation of time and consumption the model distinguishes between the partners joint and private leisure time we estimate the parameters of our model on a danish time use survey with information on time allocation and expenditures the empirical estimation leads to four main conclusions first we fi nd that assignable expenditures vary with female and male wage rates consistent with the collective model and we can assign this variation to the pareto weight being sensitive to relative wages second we fi nd that men put more weight on both their own private expenditure and composite leisure than women third we fi nd that joint leisure and individual leisure are not perfect substitutes for partners fourth we observe that both joint and private leisure are independent of the wage distribution thus togetherness is not a substitute for economic factors fifth we find that when the female wage goes up all else equal her child care hours increase while her husband s child care hours decrease

spending time and money within the household we consider both theoretically and empirically the allocation of time and money within the household the research question is whether a married person who enjoys more leisure than their partner also receives more consumption which seems to indicate the outcome of power within the household or receives less consumption which seems to indicate differing intrahousehold preferences we develop a simple parametric structural model with household production that is tested on survey data we find that relative wages have an impact on power for leisure this effect is dominated by a conventional wage effect in which the partner who has the higher wage takes less leisure

married with children a collective labor supply model with detailed time use and intrahousehold expenditure information we propose a collective labor supply model with household production that generalizes an original model of blundell chiappori and meghir 2005 in our model adults individual preferences not only depend on own leisure and individual private consumption of market goods they also depend on the consumption of domestic goods which are produced by combining goods bought on the market with individuals time we apply our model to new and unique data on dutch couples with children the data contains detailed information about the spouses time use and the intrahousehold allocation of all expenditures our application uses a novel estimation strategy that builds upon the familiar two stage allocation representation of the collective model we obtain interesting and plausible empirical results spouses preferences depend on the consumption of domestically produced goods including children s welfare in addition pareto weights depend on variables like the individual wages and the share in the household s nonlabor income finally and perhaps surprisingly we do not nd evidence that mothers care more for their children than fathers this paper draws on data of the liss panel of centerdata special thanks go to marika de bruijne and arthur van soest who helped to construct the questionnaire and to guillaume schollier

marriage markets and assortative mating with household public goods theoretical results and empirical implications this paper analyzes marriage market equilibria when the gains from marriage result from joint consumption of household public goods assuming transferable utility within marriage the paper proves that marriage markets will be characterized by positive assortative mating on wealth when spouses differ only in endowments and the gains to marriage result only from public goods when spouses differ in wages and household public goods are produced at home the results imply offsetting effects with public good economies creating an incentive for positive assortative mating on wages and gains from specialization creating an incentive for negative assortative mating on wages the results help explain the persistent lack of empirical support for becker s prediction of negative assortative mating on wages and have implications for empirical analysis of all joint living arrangement decisions

on the different survival rates of portuguese microbusinesses the case of projects supported by microcredit in spite of their importance to the micro entrepreneur s life portuguese microbusinesses exhibit a short duration in activity however until now there has been scarce attention about the determin

collective labour supply with children we extend the collective model of household behavior to allow for the existence of public consumption we show how this model allows the analysis of welfare consequences of policies aimed at changing the distribution of power within the household our setting provides a conceptual framework for addressing issues linked to the targeting of specific benefits or taxes we also show that the observation of the labor supplies and the household demand for the public good allow one to identify individual welfare and the decision process this requires either a separability assumption or the presence of a distribution factor

gender identity and relative income within households band s income we argue that this pattern is best explained by gender identity norms which induce an aversion to a situation where the wife earns more than her husband we present evidence that this aversion also impacts marriage formation the wife s labor force participation the wife s income conditional on working marriage satisfaction likelihood of divorce and the division of home production within marriage markets when a randomly chosen woman becomes more likely to earn more than a randomly chosen man marriage rates decline in couples where the wife s potential income is likely to exceed the husband s the wife is less likely to be in the labor force and earns less than her potential if she does work in couples where the wife earns more than the husband the wife spends more time on household chores moreover those couples are less satisfied with their marriage and are more likely to divorce these patterns hold both cross sectionally and within couples over time

socially responsible investing in the united states socially responsible investing sri has emerged in recent years as a dynamic and quickly growing segment of the u s financial services industry involving over 2 trillion in professionally managed assets its conceptual origins can be found in the early history of civilization with it s modern roots in the 1960s this paper provides an overview of the breadth and depth of the concept and practice of socially and environmentally responsible investing describes the investment strategies that together define sri as currently practiced in the u s offers several observations about some of the factors fueling its dramatic growth and presents data showing that investors who choose to invest in a socially and environmentally responsible manner can do so without giving up investment returns sri has matured to a point where virtually any investment need can be met through portfolio design that integrates an investor s personal values institutional mission and or social priorities the socially responsible investment industry in the unitedstates is a young phenomenon even referring to it as an industry ten years ago may have been a bit of a stretch while it has grown dramatically in recent years it is an area of work of study and of practical application that continues to evolve in many significant ways one intriguing example of the ongoing development of the field can be found in the analysis of the language used to describe it the terms social investing socially responsible investing ethical investing socially aware investing socially conscious investing green investing values based investing and mission based or mission related investing all refer to the same general process and are often used interchangeably

elevating the role of divestment in socially responsible investing the divest movement has focused attention on strategic and ethical differences in the practice of socially responsible investing sri and highlighted an unnecessary bifurcation of best of class engagement and divestment although best of class engagement is favored as a contemporary and pragmatic approach this paper calls for a more pronounced recognition of absolute dealbreakers and divestment as an underpinning for best of class engagement after linking divestment and best of class engagement to their foundations of absolutism and relativism respectively i critique best of class engagement and argue that without a distinct and explicit role for divestment best of class strategies are ethically and strategically fraught following a discussion of which types of issues suggest divestment or best of class engagement i identify the norway government pension fund as a noteworthy example and posit that divestment and engagement are best presented and employed in tandem particularly for issues that have yet to be addressed by law and convention

an analysis of new firm survival using a hazard function a unique data set is used to provide a detailed examination of the survival of newly established manufacturing firms in north east england using data on 781 firms established between 1973 and 2001 log logistic hazard models are estimated separately for i micro enterprises and ii small and medium establishments smes both micro enterprises and smes show clear evidence of positive duration dependence followed by negative duration dependence we find the two firm types are differentially affected by firm specific and macro economic variables increases in initial plant size impact negatively on micro enterprise survival and positively on sme survival

income and outcomes a structural model of intrahousehold allocation there is evidence from several sources that one cannot treat many person households as a single decision maker if this is the case then factors such as the relative incomes of the household members may affect the final allocation decisions made by the household we develop a method of identifying how incomes affect outcomes given conventional family expenditure data the basic assumption we make is that household decision processes lead to efficient outcomes we apply our method to a sample of canadian couples with no children we find that the final allocations of expenditures on each partner depend significantly on their relative incomes and ages and on the level of lifetime wealth

the identification of unobservable independent and spousal leisure this paper is based on the idea that for each partner in a marriage there are two distinct types of leisure one type is each person s independent or private leisure and the other type is spousal leisure whose importance has long been emphasized in the literature of psychology while each type of leisure is unobservable only total leisure is observed it is shown that the recent collective models of the intrahousehold allocation initiated by chiappori can be extended to identify each type of leisure up to an additive constant in particular the effects of each member s wage household unearned income and extrahousehold environmental parameters on the independent and spousal leisure and on the sharing rule are fully identified the observational requirement here is the same as in other studies namely the observation of individual labor supply individual wages household unearned income one assignable good and consumption expenditure at the household level
