money and capital abstract the effects of money anticipated inflation on capital formation is a classic issue in macroeconomics previous papers adopt reduced form approaches putting money in the utility function or imposing cash in advance but using otherwise frictionless models we follow instead a literature that tries to be explicit about the frictions making money essential this introduces new elements including a two sector structure with centralized and decentralized markets stochastic trading opportunities and bargaining these elements matter quantitatively and numerical results differ from findings in the reduced form literature the analysis also reduces a gap between microfounded monetary economics and mainstream macro

optimal interest rate rules asset prices and credit frictions we study optimal taylor type interest rate rules in an economy with credit market imperfections our analysis builds on the agency cost framework of carlstrom and fuerst 1997 agency costs net worth and business fluctuations a computable general equilibrium analysis american economic review 87 893 910 which we extend in two directions first we embed monopolistic competition and sticky prices second we modify the stochastic structure of the model in order to generate a countercyclical premium on external finance this is achieved by linking the mean distribution of investment opportunities faced by entrepreneurs to aggregate total factor productivity we model monetary policy in terms of simple welfare maximizing interest rate rules we find that monetary policy should respond to increases in asset prices by lowering interest rates however when monetary policy responds strongly to inflation the marginal welfare gain of responding to asset prices vanishes within the class of linear interest rate rules that we analyze a strong anti inflationary stance always attains the highest level of welfare

what drives corporate social performance the role of nation level institutions based on whitley s national business systems nbs institutional framework we theorize about and empirically investigate the impact of nation level institutions on firms corporate social performance csp using a sample of firms from 42 countries spanning seven years we construct an annual composite csp index for each firm based on social and environmental metrics we find that the political system followed by the labor and education system and the cultural system are the most important nbs categories of institutions that impact csp interestingly the financial system appears to have a relatively less significant impact we discuss implications for research practice and policymaking

the design of the university system abstract this paper compares the organisation of the university sector under unregulated private provision with the structure which would be chosen by a welfare maximising government it studies a general equilibrium model where students attend university to earn higher incomes in the labour market and universities teach them and carry out research each university chooses its tuition fee to maximise the amount of resources it can devote to research research bestows an externality on society government intervention needs to balance labour market efficiency considerations which would tend to equalise the number of students attending each university with considerations of efficiency on the production side which suggest that the most productive universities should teach more students and carry out more research we find that government concentrates research more that the private market would but less than it would like to do if it had perfect information about the productivity of universities it also allows fewer universities than would operate in a private system

the ir relevance of real wage rigidity in the new keynesian model with search frictions we explore the role of real wage dynamics in a new keynesian business cycle model with search and matching frictions in the labor market both job creation and destruction are endogenous we show that the model generates counterfactual inflation and labor market dynamics in particular it fails to generate a beveridge curve vacancies and unemployment are positively correlated introducing real wage rigidity leads to a negative correlation and increases the magnitude of labor market flows to more realistic values however inflation dynamics are only weakly affected by real wage rigidity this is because of the presence of labor market frictions which generate long run employment relationships the measure of real marginal cost that is relevant for inflation dynamics via the phillips curve contains a dynamic component that does not necessarily move with real wages

choosy search and the mismatch of talents this article proposes a multi sector matching model where workers have symmetric sector specific skills and the search market is segmented by sector workers choose the range of markets they are willing to participate in i identify a composition externality workers do not take into account the impact of their choice on sector specific mean productivity among the pools of job seekers consequently workers prospect too many market segments and there is room for public policy even when the so called hosios condition holds

equilibrium price dispersion with sequential search abstract the paper studies equilibrium pricing in a product market for an indivisible good where buyers search for sellers buyers search sequentially for sellers but do not meet every seller with the same probability specifically a fraction of the buyers meetings lead to one particular large seller while the remaining meetings lead to one of a continuum of small sellers in this environment the small sellers would like to set a price that makes the buyers indifferent between purchasing the good and searching for another seller the large seller would like to price the small sellers out of the market by posting a price that is low enough to induce buyers not to purchase from the small sellers these incentives give rise to a game of cat and mouse whose only equilibrium involves mixed strategies for both the large and the small sellers the fact that the small sellers play mixed strategies implies that there is price dispersion the fact that the large seller plays mixed strategies implies that prices and allocations vary over time we show that the fraction of the gains from trade accruing to the buyers is positive and nonmonotonic in the degree of market power of the large seller as long as the large seller has some positive but incomplete market power the fraction of the gains from trade accruing to the buyers depends in a natural way on the extent of search frictions

incentives and careers in academia theory and empirical analysis we study career concerns in italian academia we mould our empirical analysis on the standard model of contests formalised in the multi unit all pay auction the number of posts the number of app

rent seeking with bounded rationality an analysis of the all pay auction the winner take all nature of all pay auctions makes the outcome sensitive to decision errors which we introduce with a logit formulation the equilibrium bid distribution is a fixed point the belief distributions that determine expected payoffs equal the choice distributions determined by expected payoffs we prove existence uniqueness and symmetry properties in contrast to the nash equilibrium the comparative statics of the logit equilibrium are intuitive rent dissipation increases with the number of players and the bid cost overdissipation of rents is impossible under full rationality but is observed in laboratory experiments our model predicts this property

job search with bidder memories this paper revisits the no recall assumption in job search models with take it or leave it offers workers who can recall previously encountered potential employers in order to engage them in bertrand bidding have a distinct advantage over workers without such attachments firms account for this difference when hiring a worker when a worker first meets a firm the firm offers the worker a sufficient share of the match rents to avoid a bidding war in the future the pair share the gains to trade in this case the diamond paradox no longer holds

competitive search equilibrium in this paper i construct an equilibrium for markets with frictions which is competitive in the sense that all agents are price takers and maximize utility subject to a set of market parameters i show that the equilibrium allocation is socially optimal i also show how the competitive search equilibrium can be achieved if employers with vacancies can advertise publicly the wages they pay

welfare cost of fluctuations when labor market search interacts with financial frictions we provide a quantitative assessment of welfare costs of fluctuations in a search model with financial frictions the matching process in the labor market leads positive shocks to reduce unemployment less than negative shocks increase it we show that the magnitude of this non linearity is magnified frictions this asymmetric effect of the business cycle leads to sizable welfare costs the model also accounts for the responsiveness of the job finding rate to the business cycle as financial frictions endogenously generate counter cyclical opportunity costs of opening a vacancy and wage sluggishness

job destruction and propagation of shocks this paper considers propagation of aggregate shocks in a dynamic general equilibrium model with labor market matching and endogenous job destruction cyclical fluctuations in the job destruction rate magnify the output effects of shocks as well as making them much more persistent interactions between capital adjustment and the job destruction rate play an important role in generating persistence propagation effects are shown to be quantitatively substantial when the model is calibrated using job flow data incorporating costly capital adjustment leads to significantly greater propagation

search theoretic models of the labor market a survey we survey the literature on search theoretic models of the labor market we show how this approach addresses many issues including the following why do workers sometimes choose to remain unemployed what determines the lengths of employment and unemployment spells how can there simultaneously exist unemployed workers and unfilled vacancies what determines aggregate unemployment and vacancies how can homogeneous workers earn different wages what are the tradeoffs firms face from different wages how do wages and turnover interact what determines efficient turnover we discuss various modeling choices concerning wage determination and the meeting process including recent models of directed search

credit market imperfections labor markets and leverage dynamics in emerging economies abstract emerging economies emes have different credit and labor market structures relative to advanced economies we document that economies with larger self employment shares tend to exhibit less countercyclical leverage dynamics we build a model where formal credit markets input credit relationships and the structure of labor markets interact that 1 captures a comprehensive set of eme business cycle regularities and 2 rationalizes our new fact the interaction between firms net worth interfirm input credit and self employment underlying our framework is critical for explaining our fact and is supported by the data

a decade s debate on the nexus between corporate social and corporate financial performance a critical review of empirical studies 2002 2011 abstract theoretical discussions and empirical studies on the nexus between corporate social responsibility corporate social performance and corporate financial performance have never ceased since the origin of the concepts the development trajectories of such studies should be articulated with a view to informing practical corporate social responsibility applications and theoretical studies in the future this paper presents a critical review of relevant empirical research articles on the nexus between corporate social performance and corporate financial performance published during the ten year period from 2002 to 2011 using mixed methods of content analyses and statistical analyses the paper reviews 84 empirical studies of this kind published during the period the results indicate that despite the enormous amount of previous studies the corporate social performance and corporate financial performance nexus is a line of inquiry that remains inconclusive the pattern of corporate social performance corporate financial performance relationship research in the decade examined has shifted towards exploring the linkages between specific aspects of the two constructs the positive relationships between these specific aspects in dual directions are confirmed by most of the studies examined in this paper the paper also examines the impact of time and space change on the corporate social performance corporate financial performance nexus the findings show that researchers have gradually recognized that the relationship is not static but changes over time furthermore the paper finds that corporate social responsibility has been increasingly debated in developing countries and in specified industrial settings the review concludes that to explore the corporate social performance corporate financial performance nexus by contextualizing it in a specified community and or examine its dynamics is a promising research area that can yield significant academic and practical values

life cycle equilibrium unemployment this paper extends the job creation job destruction approach to the labor market to take into account a deterministic finite horizon as hirings and separations depend on the time over which investment costs can be recouped the life cycle setting implies age differentiated labor market flows while search by the unemployed falls with age the separation rate is rather u shaped over the life cycle worker heterogeneity in the context of undirected search implies an intergenerational externality which is not eliminated by the hosios condition we show that age specific policies are required to attain the first best allocation

the curvilinear relationship between corporate social performance and corporate financial performance evidence from the international construction industry abstract the intellectual debate concerning the nexus between corporate social performance csp and corporate financial performance cfp is incessant in recent years the debate has explored more dynamic links one of which is the curvilinear relationship between the two constructs it argues that the relationship between csp and cfp can be better captured by a u shape at a low level of csp companies are not able to cultivate social activities to achieve tangible financial benefits but after passing an inflection point csp will gradually turn into financial benefits that can offset the costs involved this research empirically tests the curvilinear relationship between csp and cfp in the context of the international construction industry using a panel data set of 30 international construction companies and 210 firm year observations over the sample period from 2007 to 2013 the curvilinear relationship of csp on return on assets and earnings per share as specific cfp measures is strongly supported this empirical finding demonstrates an opportunity for executives of international construction companies to capitalize on their social responsibility efforts and create a win win situation between csp and cfp

competing for order flow in otc markets we develop a model of a two sided asset market in which trades are intermediated by dealers and are bilateral dealers compete to attract order flow by posting the terms at which they execute trades which can include prices quantities and execution times and investors direct their orders toward dealers that offer the most attractive terms of trade equilibrium outcomes have the following properties first investors face a trade off between trading costs and speeds of execution second the asset market is endogenously segmented in the sense that investors with different asset valuations and different asset holdings will trade at different speeds and different costs for example under a leontief technology to match investors and dealers per unit trading costs decrease with the size of the trade in accordance with the evidence from the market for corporate bonds third dealers implicit bargaining powers are endogenous and typically vary across sub markets finally we obtain a rich set of comparative statics both analytically by studying a limiting economy where trading frictions are small and numerically for instance we find that the relationship between trading costs and dealers bargaining power can be hump shaped

shareholder value stakeholder management and social issues what s the bottom line we test the relationship between shareholder value stakeholder management and social issue participation building better relations with primary stakeholders like employees customers suppliers and communities could lead to increased shareholder wealth by helping firms develop intangible valuable assets which can be sources of competitive advantage on the other hand using corporate resources for social issues not related to primary stakeholders may not create value for shareholders we test these propositions with data from s p 500 firms and find evidence that stakeholder management leads to improved shareholder value while social issue participation is negatively associated with shareholder value copyright 2001 john wiley sons ltd

when does it pay to be good a contingency perspective on corporate social and financial performance would it work abstract the findings on corporate social and financial performance research has exposed the universal approach as tenuous and questionable so the current approach of corporate social and financial performance research has been subject to severe criticism instead of exploring a universal corporate social and financial performance link scholars have called for a contingency perspective in order to determine the conditions and context that catalyzes positive connections between the constructs this study systematically reviews the literature on the moderators exploited in corporate social and financial performance research and finds by and large that a positive corporate social and financial performance association dominates although the relationship is stronger in advanced economies and institutionalized contexts although research on the contingency perspective has progressed theoretical support for this relationship is thin and the lack of appropriate research design and stereotyped constructs thwart its positive implications a review of the literature shows that although organizational factors seem to moderating the corporate social and financial performance relationship strongly yet industry and country factors also tend to affect this association important consistencies included that a dynamic business environment reinforces the corporate social and financial performance relationship differentiation in social responsibility practices moderates the responsibility performance link but not often positively the effect of r d intensity is equivocal and advertising intensity did not strengthen this relationship across the level avenues for future research conclude our discussion

competitive equilibrium and the core in club economies with anonymous crowding in club economies with anonymous crowding competitive equilibrium states of the economy are efficient and coincide with the core when there is only one private good anonymous admission prices permit consumers with different tastes to share facilities consumers might do so when their demands for facility size and crowding coincide in which case sharing is efficient thus similarity of demands is the relevant consideration for efficiently grouping consumers with different tastes

lending relationships and labor market dynamics abstract motivated by a negative link between credit spreads and labor force participation lfp and a positive link between these spreads and unemployment over the business cycle we study the role of lfp as an amplification mechanism of financial shocks in a labor search model with endogenous lfp lending relationships and credit market disruptions amid aggregate productivity and financial shocks that replicate the empirical volatility of lfp and credit spreads the model produces highly volatile unemployment and vacancies countercyclical credit spreads and unemployment and procyclical lfp when we quantitatively match the cyclical behavior of credit spreads the interaction between endogenous lfp and financial shocks gives rise to much sharper vacancy fluctuations and plays a key role in generating quantitatively factual cyclical labor market dynamics

on the determinants of corporate social responsibility international evidence on the financial industry this article sets out to undertake a thorough point by point examination of the theory postulated by campbell 2007 in which an attempt is made to specify the conditions under which corporations may or may not act in socially responsible ways in order to ensure the overall reliability of our study and to attempt to provide a new understanding of and greater insights into whether corporate social responsibility csr is affected by financial and institutional variables we empirically investigate a total of 520 financial firms in 34 countries between the years 2003 and 2005 our empirical findings are i firms with larger size are more csr minded and the financial performance and csr are not related ii firms would actually act in more socially responsible ways to enhance their competitive advantages when the market competitiveness is more intense iii financial firms in countries with stronger levels of legal enforcement tend to engage in more csr activities however interestingly and rather strikingly those firms in countries with stronger shareholder rights tend to engage in less csr activities and iv self regulation within the financial industry has a significantly positive effect on csr with firms being found to act in more socially responsible ways in those countries which have more cooperative employer employee relations higher quality management schools and a better macroeconomic environment

do sustainable companies have a better financial performance a study on brazilian public companies abstract increasingly companies are taking initiatives to mitigate the negative social and environmental impacts to address the emerging needs of society in the financial realm stock markets created indices to offer investors the option to prioritize sustainable companies in brazil the initiative came from the sao paulo stock exchange by releasing the corporate sustainability index in this paper we analyze the financial and economic performance of companies listed in the corporate sustainability index in comparison with the performance of companies listed in the sao paulo stock exchange index for that profitability and liquidity ratios were calculated and statistical tests specifically cluster and nonparametric analysis were performed to validate possible trends similarities or differences observed in each group of companies based on our analysis we found no evidence of economic and financial performance differences between companies from each of the studied indices in fact our findings show that other characteristics such as sectorial classification have more influence on firms economic and financial performance than their investments in sustainable initiatives the research contributes to the body of knowledge in the field of corporate sustainability by utilizing a different methodology than similar studies have used incorporating different accounting ratios and new statistical analyses of data from the emerging brazilian market

job matching and propagation in the u s labor market the vacancy unemployment ratio and employment react sluggishly to productivity shocks we show that the job matching model in its standard form cannot reproduce these patterns due to excessively rapid vacancy responses extending the model to incorporate sunk costs for vacancy creation yields highly realistic dynamics creation costs induce entrant firms to smooth the adjustment of new openings following a shock leading the stock of vacancies to react sluggishly

equilibrium wage dispersion and interindustry wage differentials this paper develops a search theoretic explanation of interindustry wage differentials given coordination problems in the labor market the probability of filling a vacancy is an increasing function of the wage offered in equilibrium firms that find vacancies more costly will offer higher wages the model thus explains the persistence of interindustry wage differentials and their correlation with industry average capital labor ratio and profitability additionally the model predicts that high wage firms will receive more applications per job opening and that wages in the labor market will behave as strategic complements

corporate social performance and its relation with corporate financial performance international evidence in the banking industry abstract the economic and financial crisis that began in 2008 has raised concerns over the impact of corporate social performance csp on corporate financial performance cfp the controversies and scandals in regard to the role of banks in the crisis have revealed failures in some csp dimensions and questioned the csr policies of banks as a real strategic commitment to the main stakeholders the financial sector has been one of the hardest hit by the crisis we study whether banks adopted a strategic approach to csp and the extent to which this approach attenuated the decrease in cfp during the crisis to that end we analyze the effect of four csp dimensions on the cfp of 154 financial entities in 22 countries most of them notably affected by the crisis from 2005 to 2010 the results show that banks with better employee relationships and corporate governance had better cfp nevertheless the crisis negatively moderated this effect in the latter suggesting failures in corporate governance mechanisms contrary to what was expected the product responsibility dimension did not positively influence cfp we found evidence that during the crisis better relations with the community could be valued positively by investors which in turn increases cfp the results are relevant for managers and policymakers we recommend that banks incorporate csp concerns into their corporate governance mechanisms review their commitment to customers and attach greater importance to relations with the community moreover regulatory reforms are suggested to clarify the responsibilities of financial institutions in the design and marketing of banking products

incentives in academics why is there tenure this paper models ancademic department as an internal labor market the major problem facing the university administration is to ensure that members of its departments are willing to hire the best possible candidates academic tenure is seen to be a necessary condition for this the analysis is also consistent with other aspects of the academic environment including tenure track appointments contract buy outs early retirement plans and when a budget crunch hits the elimination of entire departments the results extend in a simple way to other organizations in which members have an input into overall decisions

a comparison of multiple unit all pay and winner pay auctions under incomplete information this article examines the properties of independent private value all pay and winner pay auctions when there are multiple units sold we study bidding behavior efficiency and revenue in a set of 23 experimental sessions our data show that the all pay auction and the winner pay auction are empirically revenue equivalent though both yield higher revenue than the risk neutral bayesian equilibrium our evidence also suggests that the winner pay auction is more likely to lead to a pareto efficient allocation than the all pay auction

virtuous nexus between corporate social performance and financial performance a study of construction enterprises in china abstract although business and society are thought in a vicious relationship for diminishing trust among stakeholders a few studies indicate the existence of a reciprocal nexus between corporate social performance and corporate financial performance known as the virtuous cycle despite of some empirical studies in developed countries little research has been conducted concerning the assumption in emerging markets where large companies have more responsibilities to create positive and sustainable shared values this paper aims to explore the nexus between social performance and financial performance of chinese companies for their global influential social and environmental impacts together with increasing awareness of corporate social responsibility csr a two step longitudinal design including cross lagged correlation analyses and longitudinal path analyses is applied to examine the overall and decomposed links it is found the virtuous cycle does exist in the overall and in most decomposed links within the context of large construction companies in china these findings are beneficial for interested policy makers corporate managers and the public to create shared value on csr and therefore contribute to csr improvements analysis results indicate a one year time lag to be appropriate for examining the lead lag relationship between corporate social performance and financial performance the research also inspires a potential generalisation of the virtuous cycle by similarly examining it in other industries or other countries with diverse csr contexts

a search model of rental markets who should pay the commission abstract we develop a dynamic search equilibrium model of rental markets with brokerage fees an endogenous mass of landlords and tenants is active in the search market while the mass of entering tenants is exogenous the mass of entering landlords is endogenously determined by the rate at which apartments become vacant brokerage fees paid by tenants are used as a device to screen short term and long term tenants we analyze a policy that requires fees to be paid by landlords such a policy decreases efficiency by preventing efficient screening but also increases turnover and hence efficiency in the search market we further provide empirically testable implications of our theory

frictional assignment i efficiency abstract this paper examines the two sided matching problem where the agents on each side of the market are heterogeneous and the matching process is time consuming this is cast in a labor market setting where workers of different skills match with different machine qualities i characterize the efficient allocation and then show that it can be decentralized by a market mechanism the efficient assignment is not always positively assortative despite the fact that machine qualities and skills are complementary in production to decentralize the efficient allocation the market mechanism requires the firms to post wages and commit each machine quality to a particular skill implications on wage inequality are briefly examined journal of economic literature classification numbers j31 e24 j64

corporate reputation and philanthropy an empirical analysis this paper analyzes the determinants of corporate reputation within a sample of large uk companies drawn from a diverse range of industries we pay particular attention to the role that philanthropic expenditures and policies may play in shaping the perceptions of companies among their stakeholders our findings highlight that companies which make higher levels of philanthropic expenditures have better reputations and that this effect varies significantly across industries given that reputational indices tend to reflect the financial performance of organizations above other factors fryxell g e and j wang 1994 journal of management 20 1 14 and that elements of the literature emphasise that discretionary aspects of social responsibility including corporate donations may not be in the financial interests of organizations e g friedman m 1970 the social responsibility of business is to increase its profits new york times magazine september 13 this is a significant finding it suggests that philanthropic expenditures may play a significant role in stakeholder management and may in particular lead to stakeholders holding more positive impressions of philanthropic corporations

optimal unemployment insurance in search equilibrium should unemployment benefits be paid indefinitely at a fixed rate or should the rate decline or increase over a worker s unemployment spell we examine these issues using an equilibrium model of search unemployment the model features worker firm bargaining over wages free entry of new jobs and endogenous search effort among the unemployed the main result is that an optimal insurance program implies a declining benefit sequence over the spell of unemployment numerical calibrations of the model suggest that there may be nontrivial welfare gains associated with switching from an optimal uniform benefit structure to an optimally differentiated system

sorting versus screening search frictions and competing mechanisms in a market where sellers compete by posting trading mechanisms we allow for a general search technology and show that its features crucially affect the equilibrium mechanism price posting prevails when meetings are rival i e when a meeting by one buyer reduces another buyer s meeting probability under price posting buyers reveal their type by sorting ex ante only if the meeting technology is sufficiently non rival price posting is not an equilibrium multiple buyer types then visit the same sellers who screen ex post through auctions

environmental policy and the equilibrium rate of unemployment abstract this paper integrates environmental policy instruments with the theory of equilibrium unemployment we investigate the question of whether a low equilibrium rate of unemployment and a high quality of the environment are complementary policy goals or must be traded off it turns out that an interval exists for a tax on emissions where the two goals are indeed complementary the tax stimulates the emergence of an abatement sector which provides pollution control and vacancies for the job seekers for constrained efficiency the policy maker operates five instruments to internalize the environmental and the search externalities a tax on emissions employment subsidies and recruiting allowances for the polluting industries are sufficient to implement the first best the optimal emission tax is an increasing function of the workers bargaining strength for labor markets where workers have a strong bargaining position the optimal pollution tax may easily exceed the pigouvian tax

rigging the lobbying process an application of the all pay auction textabstractin a world where a politician can explicitly auction off a prize to the high bidder the standard auction literature can be used to analyse political behavior the justice system however precludes politicians from explicitly selling the prize to the highest bidder thus politicians cannot let it become public knowledge that they are in the business of selling political favors an institution has emerged in political markets to overcome this constraint which are termed as lobbying lobbyists make implicit payments to the politician through campaign contributions if these up front payments were rebated to those failing to receive the prize it would be clear that the politician was selling favors this article has examined an interesting principle arising in all pay auctions this principle states that a politician wishing to maximize political rents may find it in his best interest to exclude certain lobbyists from participating in the lobbying process particularly lobbyists valuing most the political prize

tax smoothing in frictional labor markets we re examine the optimality of tax smoothing from the point of view of frictional labor markets our central result is that whether or not this cornerstone optimal scal policy pre

demand shocks and open economy puzzles abstract we pose good markets frictions on top of an otherwise standard two country international real business cycle irbc model shopping for goods takes effort which prevents perfect matching between customers and producers an increase in search effort implies increased measured productivity demand shocks increase expenditures and search effort simultaneously increasing output consumption productivity and the trade deficit and appreciating the real exchange rate thus we solve the backus smith puzzle and we show that the cross country correlation of consumption is higher than that of output standard irbc models cannot account for these puzzles along with movements in tfp

taxation and redistribution of residual income inequality this paper studies the optimal redistribution of income inequality caused by the presence of search and matching frictions in the labor market we study this problem in the context of a directed search model of the labor market populated by homogeneous workers and heterogeneous firms the optimal redistribution can be attained using a positive unemployment benefit and an increasing and regressive labor income tax the positive unemployment benefit serves the purpose of lowering the search risk faced by workers the increasing and regressive labor tax serves the purpose of aligning the cost to the firm of attracting an additional applicant with the value of an application to society

all pay contests this paper studies a class of games all pay contests which capture general asymmetries and sunk investments inherent in scenarios such as lobbying competition for market power labor market tournaments and r d races players compete for one of several identical prizes by choosing a score conditional on winning or losing it is weakly better to do so with a lower score this formulation allows for differing production technologies costs of capital prior investments attitudes toward risk and conditional and unconditional investments among others i provide a closed form formula for players equilibrium payoffs and analyze player participation a special case of contests is multiprize complete information all pay auctions

analysis of social performance in the spanish financial industry through public data a proposal banking firms are becoming increasingly aware that their clients management of environmental and social risks may in term threaten their own business as lenders and investors in addition stakeholders are requiring banks to improve their social performance as a result some banks are developing corporate social responsibility csr policies and management systems to reduce potential risks and improve their performance in the spanish financial system half of the banking firms are savings banks most of which have always used some corporate social responsibility csr criteria in their management private banks have only recently started to integrate social aspects in their performance however no formal analysis has been carried out on the impact of csr strategies various initiatives have been launched nationally and internationally to include the social dimension in management systems the purpose of this research is to analyse the social performance of the main spanish financial companies through public data such as social or sustainability reports and media sources in order to do this we need to determine which csr criteria most greatly affect banking firms and to choose the most accurate quantitative and qualitative indicators to measure social performance

informative price advertising in a sequential search model the purpose of this paper is to study the role and implications of price advertising when shopping trips are costly to consumers to do so we introduce advertising into an optimal sequential search model information about prices is both gathered by consumers and disseminated by firms consumers search sequentially and stores advertise with various intensity when it is in their interest to do so our model has a unique equilibrium exhibiting priee dispersion the model generates predictions about the shape of the price distribution and firms advertising behavior we explore the effects of entry and find that when initial advertising costs at zero level of effort are precisely zero entry drives the equilibrium to the perfectly competitive outcome however when initial marginal advertising costs are positive entry drives prices higher and while the informed consumers almost surely locate competitive prices welfare does not necessarily increase finally we compare the effectiveness of the two informational channels when advertising costs shrink prices become competitive however when search costs shrink prices remain bounded above marginal production costs

the unemployment volatility puzzle is wage stickiness the answer i discuss the failure of the canonical search and matching model to match the cyclical volatility in the job finding rate i show that job creation in the model is influenced by wages in new matches i summarize microeconometric evidence and find that wages in new matches are volatile and consistent with the model s key predictions therefore explanations of the unemployment volatility puzzle have to preserve the cyclical volatility of wages i discuss a modification of the model based on fixed matching costs that can increase cyclical unemployment volatility and is consistent with wage flexibility in new matches

ex ante price offers in matching games non steady states a matching problem is considered in which sellers can publicly commit to a trading price that differs from the price at which buyers expect to trade elsewhere in the market when demand and supply are nearly equal the equilibrium ex ante price offer lies below the price associated with the nash bargaining split this relationship reverses when the level of excess demand is large sellers always have an incentive to make ex ante offers when prices elsewhere are determined by nash bargaining this can be interpreted to mean that nash bargaining is an unstable pricing institution copyright 1991 by the econometric society

the external finance premium and the macroeconomy us post wwii evidence abstract the central variable of theories of financial frictions the external finance premium is unobservable this paper distils the external finance premium from a dynamic stochastic general equilibrium dsge model estimated on us macroeconomic data covering the period 1954 to 2004 within the dsge framework movements in the premium can be given an interpretation in terms of shocks driving business cycles a key result is that the estimate based solely on non financial macroeconomic data picks up over 70 of the dynamics of lower grade corporate bond spreads the paper also identifies a gain in fitting key macroeconomic aggregates by including financial frictions in the model and documents how shock transmission is affected

business cycles and labor market search the quantitative implications of labor market search for economic fluctuations are evaluated in the context of a real business cycle model incorporating labor market search into the model is found to improve its empirical performance along several dimensions in particular hours now fluctuate substantially more than wages and the contemporaneous correlation between hours and productivity falls in addition the model replicates the observation that output growth displays positive autocorrelation at short horizons overall the empirical results suggest that the labor market search environment embodies a quantitatively important propagation mechanism copyright 1996 by american economic association

wage differentials discrimination and efficiency abstract i analyze a large labor market where homogeneous firms post wages to direct the search of workers who differ in productivity i show that the model has a unique equilibrium the wage differential depends positively on the workers productivity differential only when the latter is large when the productivity differential is small high productivity workers get a lower wage than low productivity workers this reverse wage differential remains even when the productivity differential shrinks to zero however the equilibrium is socially efficient high productivity workers always get the employment priority and higher expected wages than low productivity workers although discrimination in terms of expected wages does not exist conventional measures are likely to incorrectly find discrimination in the model

costly external finance and labor market dynamics abstract we study the role of agency frictions and costly external finance in cyclical labor market dynamics with a focus on how credit market frictions may amplify aggregate tfp shocks the main result is that aggregate tfp shocks lead to large fluctuations of labor market quantities if the model is calibrated to the empirically observed countercyclicality of the finance premium a financial accelerator mechanism thus amplifies labor market fluctuations by rendering rigidity in real wage dynamics in contrast if the finance premium is procyclical which the model can be parameterized to accommodate amplification is absent and labor market fluctuations display the shimer 2005 puzzle

monetary policy and labor market frictions a tax interpretation replicating the flexible price allocation in models with nominal rigidities and labor market frictions that lead to an inefficient matching of unemployed workers with job vacancies even if feasible is generally not desirable we characterize the tax instruments that implement the first best allocation and examine the trade offs faced by monetary policy if these tax instruments are unavailable our tax interpretation helps explain why the welfare cost of inefficient labor market search can be large while the incentive to deviate from price stability is small gains from deviating from price

corporate social responsibility in the banking industry motives and financial performance abstract the current study investigates the association between corporate social responsibility csr and financial performance fp and discusses the driving motives of banks to engage in csr three motives namely strategic choices altruism and greenwashing suggest that the relationship between csr and fp is positive non negative and non existent respectively we obtained our sample which covered 2003 2009 from the ethical investment research service eiris databank and bankscope database the data consists of 162 banks in 22 countries we then classified the banks into four types based on their degree of engagement in csr this study proposes the use of an extended version of the heckman two step regression in which the first step adopts a multinomial logit model and the second step estimates the performance equation with the inverse mills ratio generated by the first step the empirical results show that csr positively associates with fp in terms of return on assets return on equity net interest income and non interest income in contrast csr negatively associates with non performing loans hence strategic choice is the primary motive of banks to engage in csr

borrowing constraints collateral fluctuations and the labor market abstract this paper studies the effects of changes in collateral requirements on the cyclical properties of unemployment and job creation i develop a general equilibrium model in which labor market frictions prevent the costless adjustment of employment financial frictions arise from an imperfect enforcement contract an environment in which borrowing limits are linked to the firm s physical capital stock can quantitatively account for the sluggish response of labor market variables to productivity shocks i find that fluctuations in those variables are mainly driven by changes in financial conditions the model can explain 75 of the variation in job creation observed in the data and it can also account for the persistent reduction in both output and leverage that follows a contraction in credit availability

a walrasian theory of markets with adverse selection the paper describes a walrasian theory of markets with adverse selection and shows how refinements of equilibrium can be used to characterize uniquely the equilibrium outcome equilibrium exists under standard conditions it is shown that under certain conditions a stable set exists and is contained in a connected set of equilibria for generic models there exists a stable outcome that is all the equilibria in the stable set have the same outcome these ideas are applied to markets with one sided and two sided uncertainty under standard monotonicity conditions it is shown that the stable outcome is separating and implies a particular pattern of matches of buyers and sellers

pareto inefficiency of market economies search and efficiency wage models this paper shows that market economies with search and in which wages are affected by efficiency wage considerations are not constrained pareto efficient wages are not set at pareto efficient levels nor is the level of employment unemployment pareto efficient we identify the nature of the biases and the welfare improving government interventions this abstract was borrowed from another version of this item

the corporate social performance financial performance link strategic managers are consistently faced with the decision of how to allocate scarce corporate resources in an environment that is placing more and more pressures on them recent scholarship in strategic management suggests that many of these pressures come directly from sources associated with social issues in management rather than traditional arenas of strategic management using a greatly improved source of data on corporate social performance this paper reports the results of a rigorous study of the empirical linkages between financial and social performance corporate social performance csp is found to be positively associated with prior financial performance supporting the theory that slack resource availability and csp are positively related csp is also found to be positively associated with future financial performance supporting the theory that good management and csp are positively related 1997 by john wiley sons ltd
