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

modelling the joint determination of household labour supplies and commodity demands in addition to choosing the allocation of total expenditure between commodities households may also be able to make decisions over the allocation of their time between market work and leisure in both theoretical and empirical work it has often been the case that these decisions have been analysed separately in this paper we stress the theoretical attractions of considering the joint determination of the allocation of time between work and leisure and the allocation of total expenditure between commodities in a utility maximising framework using a sample of individual households we attempt to evaluate the empirical importance of the joint determination model over the separate determination of labour supplies and commodity demands our approach follows that of abbott and ashenfelter i976 phlips i978 barnett i979 deaton and muellbauer i980 and atkinson and stern i980 here we pay particular attention to the following four important aspects of household decision making over commodity demand and labour supply the first concerns the commonly assumed restriction on the household s preferences of weak separability between goods and leisure this assumption allows the estimation of commodity demand systems and engel curves that exclude wage rate variables in cross section household budget data with large variation in wage rates across the sample the invalidity of this assumption would involve a serious mis specification any correlation between the excluded wage variable and the included price income and demographic variables would lead to biased parameter estimates and hence biased estimated elasticities similarly this assumption allows the estimation of labour supply curves that exclude relative price variables and its invalidity could produce biased labour supply elasticities a second aspect of household decision making which we wish to highlight arises from the suspicion commonly alluded to in labour economics texts that primary male workers may not be free to choose their hours of work thus we estimate a matched pair of rationed and unrationed systems following the work of neary and roberts i 980 and deaton and muellbauer i 979 the separability restriction is not unrelated to this point since without it we will see that the rationed hours of work enter demand systems in a complex fashion in effect

global value chain governance a relational perspective global value chain gvc governance is an established field within international business research yet the relational aspects of gvcs have to date garnered less scholarly attention than have efficiency considerations this conceptual study s objective is to explore the relational dynamics of gvc governance using an internalization theory perspective and by linking gvc research with insights from the business network literature gvcs are argued to be a distinct form of asymmetrical networks associated with economizing and capability creation features as well as costs the orchestrating firm can thus enhance efficiency outcomes of the gvc using social mechanisms similar to those adopted by core actors in a business network in the study six such mechanisms were identified 1 selectivity 2 inclusion of non business intermediaries 3 joint strategizing 4 relational capital 5 multilateral feedback and 6 rules for equitable value distribution while safeguarding the gvc s efficiency the above social mechanisms are associated with challenges and limitations and therefore do not guarantee international competitive success however deployed in an integrative fashion these social mechanisms facilitate coordination thus economizing on bounded rationality reduce the hazards of imperfect effort by partners thus economizing on bounded reliability and foster innovation and new capability development

labour supply specification and the evaluation of tax reforms this paper investigates the practical importance of the functional specification of labour supply equations for the analysis of tax benefit reform we consider two labour supply specifications one derived from stone geary preferences and the other from a generalisation that relaxes some of the more critical restrictions in that model we use these equations to contrast the effects of two reforms to the u k income tax system one involves income effects almost exclusively while the other implies a significant number of large increases in marginal tax rates

promotions and incentives in partnerships evidence from major u s law firms this paper develops a model of promotions in partnerships and estimates the model using cross sectional data on major u s law firms promotions to partner screen associates for firm specific skills and they generate tournament incentives among associates competing for promotions the key parameters of the model are estimated by imposing the equilibrium restriction that firms offer equal utility to incoming associates the incentive component of compensation is found to be statistically significant and a nested model without promotion

habits hysteresis and catastrophes in labor supply abstract this paper investigates the implications of a general model of locally unstable habit formation with respect to consumption household time and corporate time the model is shown to imply multiple long run equilibria exhibiting hysteresis and catastrophes dependent on rationings and the wage rate this can explain profound changes in labor supply preferences and behavior such as when long term unemployed become little motivated to get a new job or when former housewives develop a strong orientation towards paid work

aggregate consumer behaviour and the measurement of inequality this paper presents an approach to inequality measurement based on an econometric model of aggregate consumer behaviour the novel feature of this model is that systems of individual demand functions can be recovered uniquely from the system of aggregate demand functions we present methods for evaluating social welfare based on an explicit social welfare function this social welfare function incorporates measures of individual welfare based on indirect utility functions for all consumer units we develop indexes of inequality based on actual and potential levels of social welfare

international connectedness and local disconnectedness mne strategy city regions and disruption much of the rising international connectedness of city regions has developed from mnes replacing local connections with superior international ones this often creates local disconnectedness that energizes the current populist backlash against mne activities we develop approaches to new ib theory addressing the interdependencies of mnes and city regions that we propose as a crucial avenue for future research we contrast two generic mne strategies the first is the traditional one the global orchestration of resources and markets we argue that it exacerbates local disconnectedness the second that we call local spawning involves engaging with the local entrepreneurial eco system to create and renew local connectedness diffusing populist responses some mnes are better able to implement a local spawning strategy due to industry factors like innovation clock speed and firm characteristics like organizational path dependency finally we distinguish between disconnection which is an outcome of mne strategy and global disruptions like the coronavirus covid 19 pandemic which are primarily stochastic events addressing disconnections requires mnes to re orient their strategies while dealing with disruptions requires undertaking risk mitigation we present empirical evidence from city regions around the world to illustrate our theory

two stage residual inclusion estimation addressing endogeneity in health econometric modeling the paper focuses on two estimation methods that have been widely used to address endogeneity in empirical research in health economics and health services research two stage predictor substitution 2sps and two stage residual inclusion 2sri 2sps is the rote extension to nonlinear models of the popular linear two stage least squares estimator the 2sri estimator is similar except that in the second stage regression the endogenous variables are not replaced by first stage predictors instead first stage residuals are included as additional regressors in a generic parametric framework we show that 2sri is consistent and 2sps is not results from a simulation study and an illustrative example also recommend against 2sps and favor 2sri our findings are important given that there are many prominent examples of the application of inconsistent 2sps in the recent literature this study can be used as a guide by future researchers in health economics who are confronted with endogeneity in their empirical work

poverty and the forward falling labor supply function a microeconomic analysis abstract existing subsistence efficiency target income and limited aspiration theories impose a backward bending labor supply behavior on poor workers in less developed countries recent empirical studies of worker behavior in the unorganized sectors of ldcs contradict this view and report evidence of both a forward falling and an upward rising labor supply this study formulates an increasing elasticity of substitution utility function model to analyze the observed behaviors the function displays both nonhomotheticity and variable elasticity properties and is capable of generating labor supply curves with forward falling and upward rising segments while the upward rising supply is considered to be usual worker behavior the forward falling segment represents a below subsistence distress sale phenomenon and the subsistence income of the worker is implied to occur at the turning point joining the two segments of the supply curve econometric estimates of the utility and the labor supply functions provide support to the theoretical results

welfare analysis of tax reforms using household data abstract this paper discusses a methodology for calculating the distribution of gains and losses from a policy change using data for a large sample of households estimates are based on the equivalent income function which is money metric utility defined over observable variables this enables calculations to be standardised and a computer program to compute the statistics presented in the paper is available for a general demand system equivalent income is related to measures of deadweight loss and standard errors are computed for each of the welfare measures an application to u k data for 5 895 households is given which simulates a reform that involves eliminating housing subsidies

experimental evidence on the importance of competing for profits on forecasting accuracy abstract subjects forecasts of the price of a stock were compared across two experiment conditions payments were determined by a tournament based on forecasting accuracy with the conditions differing in the number of subjects earning positive profits the results suggest that subjects who consistently lost money learned to form more accurate forecasts than others who consistently made positive profits the implications of these results for learning in markets are discussed in terms of previous research in which competition for profits was seen as continually driving participants in markets toward making better decisions

an index of inequality with applications to horizontal equity and social mobility horizontal equity and social mobility are discussed in terms of a non utilitarian social welfare function which takes account of the process by which an ex ante distribution is mapped into an ex post distribution by the tax system for example an index of inequality is proposed which decomposes into two components corresponding to vertical and horizontal equity respectively a functional form for the social welfare function is derived for the purposes of empirical work and an application to data for 5895 uk households is presented the paper contains a theoretical application of the index to a model of optimal taxation it is conventional to assess the merits of alternative public policies in terms of a trade off between equity and efficiency in practice however a change in say the tax system involves three effects first it may have incentive or disincentive effects leading to efficiency gains or losses secondly it may alter the distribution of welfare levels thirdly it may alter the ranking of individuals or households within the distribution these three effects correspond to efficiency vertical equity and we shall argue certain aspects of horizontal equity respectively and any assessment of a tax change must take into account all three the principal assumption of this paper is that government is concerned about the trade off between these three effects a strict utilitarian is concerned only with the consequences of an action and in the evaluation of a particular reform a utilitarian measure of social welfare is defined over the vector of ex post utilities no account is taken of the process by which the vector of ex ante utilities is mapped into the ex post vector and no ethical status is awarded to the ex ante distribution one does not have to adopt an entitlement theory of justice to believe that the utilitarian approach may ignore some relevant considerations such as the fairness of the redistributive process a striking example of this arises in the model used by mirrlees 11 to examine optimal income taxation in that model individuals have identical preferences defined over consumption and leisure and differ only in respect of their potential wage rates or ability levels clearly in the absence of taxation individual utility is an increasing function of ability suppose the government uses redistributive lump sum taxes to achieve the first best optimum then as mirrlees 11 12 shows the first best optimum for a utilitarian social welfare

do tournaments have incentive effects much attention has been devoted to studying models of tournaments or situations in which an individual s payment depends only on his or her output or rank relative to that of other competitors academic interest derives from the fact that under certain sets of assumptions tournaments have desirable normative properties because of the incentive structures they provide our paper uses nonexperimental data to test whether tournaments actually elicit effort responses we focus on professional golf tournaments because information on the incentive structure prize distribution and measures of individual output players scores are both available we find strong support for the proposition that the level and structure of prizes in pga tournaments influence players performance

configurations of strategy and structure in subsidiaries of multinational corporations a three fold typology of subsidiary roles world mandate specialized contributor local implementer was induced from the literature and its empirical validity was confirmed adopting a configurational approach we then explored the ways in which subsidiary structural context varies across subsidiary role types structural context characteristics were determined through a discussion of the underlying principles of the hierarchy and heterarchy models of multinational organization the key findings were a higher strategic autonomy in world mandates than in local implementers b a more internationally configured value chain in world mandates and specialized contributors than local implementers c lower levels of internal product flows in world mandates than the other two types and d a significantly lower performance in specialized contributors implications for a configurational model of subsidiary management and for heterarchy as a higher level conceptualization are discussed

gender and competition at a young age gender gaps may be observed in a variety of economic and social environments one of the possible determining factors is that men are more competitive than women and so when the competitiveness of the environment increases the performance of men increases relative to that of women we test this hypothesis in a field study conducted with 9 year old children running on a track they first run alone and then in pairs over a short distance with different gender composition of the pairs the results support the hypothesis that performance in competition varies according to gender when children ran alone there was no difference in performance in competition boys but not girls improved their performance this finding relates to the discussion regarding single sex schools the outcomes of examinations in a mixed sex school can show a gender gap in favor of boys even when this gap does not reflect actual abilities girls who are as talented as boys will end up performing worse just because they are not as competitive and will not achieve as high scores in examinations as boys

social capital and localised learning proximity and place in technological and institutional dynamics this conceptual paper analyses why social capital is important for learning and economic development how it is created and its geography it argues that with the rise of globalisation and learning based competition social capital is becoming valuable because it organises markets lowering business firms costs of co ordinating and allowing them flexibly to connect and reconnect the paper defines social capital as a matrix of various social relations combined with particular normative and cognitive social institutions that facilitate co operation and reciprocity and suggests that social capital is formed at spatial scales lower than the national or international because the density of matrices of social relations increases with proximity the paper also offers a discussion of how national and regional policies may be suited for promoting social capital

new product strategy and industry clockspeed we study how industry clockspeed internal firm factors such as product development production and inventory costs and competitive factors determine a firm s optimal new product introduction timing and product quality decisions we explicitly model market demand uncertainty a firm s internal cost structure and competition using an infinite horizon markov decision process based on a large scale numerical analysis we find that more frequent new product introductions are optimal under faster clockspeed conditions in addition we find that a firm s optimal product quality decision is governed by a firm s relative costs of introducing new products with incremental versus more substantial improvements we show that a time pacing product introduction strategy results in a production policy with a simple base stock form and performs well relative to the optimal policy our results thus provide analytical support for the managerial belief that industry clockspeed and time to market are closely related

on the size of the gender difference in competitiveness we design a new procedure for measuring competitiveness and use it to estimate the magnitude of the gender gap in competitiveness before working on a task participants choose what percentage of their payoffs will be based on a piece rate compensation scheme the rest of their payoff is allocated to a competitive compensation scheme this novel procedure allows us to distinguish between 101 levels of competitiveness as opposed to the binary measure used in the literature whereas the binary measure allows researchers to conclude that about twice as many men as women choose to compete typically two thirds versus one third the new procedure sheds light on the intensive margin we find that the intensity of the preference is more extreme than the binary measure could detect for example we find that only one fifth of the most competitive 25 of our participants are women and the most competitive 10 of our participants are all men the new procedure also allows us to study the correlation between comp

estimating utility consistent labour supply functions some results on pooled budget data abstract demand systems aids les are augmented to include labour supply and then estimated on pooled u k budget data allowing for time series and cross section variation in wages the results point to the danger of constraining the labour supply curve a priori by use of restrictive utility systems in addition hypothesis relating to effects of price wage movements on composition of full income are tested

the importance of being confident gender career choice and willingness to compete abstract this study investigates the extent to which gender differences in choosing to enter competitive tournaments are due to women s lower taste for competition or differences in confidence we examine three types of confidence and find that confidence measured by expected ranking is the most important determinant of decisions to enter tournaments conditional on ability this measure eliminates gender differences in winner take all tournaments and when entered with risk measures eliminates differences in ranked compensation tournaments when the sample is split by career choice there are no gender differences for students in stem fields and in the humanities and the social sciences differences can be explained by confidence however for business school students gender differences in willingness to compete in winner take all tournaments persist even after accounting for risk aversion and confidence men in business set themselves apart from the rest of the population men and women alike with the highest levels of tournament entry and the most positive performance responses to competition

beijing or shanghai the strategic location choice of large mnes host country headquarters in china we argue that a multinational enterprise s mne s location choice for its host country headquarters hchq in the geographic space of the host country is determined by the interplay between the strategic roles of hchq in the organizational space of the mne and the institutional space external and internal to the mne we focus on the location choice between beijing and shanghai we test our arguments using data for a sample of fortune global 500 corporations in china 1979 2005 this study contributes to international business ib research by reinvigorating research on hchq we also complement economic geography research on subnational agglomeration by using an ib perspective with a focus on the institutional idiosyncrasies of cities

testing the theory of tournaments an empirical analysis of broiler production broiler chickens are raised by contract growers whose rewards depend explicitly upon relative performance we use data on the performance of broiler producers facing both tournament and linear performance evaluation compensation structures to test three predictions from the theory of tournaments that changes in the level of prizes that leave prize differentials unchanged will not affect performance that in mixed tournaments more able players will choose less risky strategies and that tournament organizers will attempt to handicap players of unequal ability or reduce mixing to avoid the disincentive effects of mixed tournaments our evidence is consistent with each prediction

land holdings living standards and labour supply functions evidence from a poor agrarian economy recent empirical studies of labour supply in ldc agriculture show both positive and negative sloping curves contrary to the traditional claims that such functions are backward bending in this study the causes for these differing results are traced empirically to the economic status of workers and the level of development of their villages in sharp contrast to prior assertions that workers in developing nations are limited by low aspirations

the incentive effects of tournaments revisited evidence from the european pga tour this analysis of data from the 1987 european men s professional golf association pga tour strongly supports the hypothesis that the level and structure of prizes in pga tournaments influence players performance specifically players performance appears to vary positively with both the total money prizes awarded in a tournament and the marginal return to effort in the final round of play a value that varies among players largely depending on how the prize money is allocated among finishers of different ranks the authors suggest that these results together with the similar results of their earlier study of the 1984 u s men s pga tour may have implications for the design of compensation systems for certain groups of workers such as corporate executives college professors and salespeople

intra household labor supply migration and subsistence constraints in a risky environment evidence from rural el salvador abstract we investigate the use of intra household labor allocation as a means of risk coping when subsistence constraints matter in rural el salvador we show that households increase the labor supply of its male members to the family farm and abroad in the us after being subjected to adverse agricultural productivity shocks the latter is the result of a standard substitution effect whereas the former is the result of subsistence concerns theoretically these results are not at odds with each other if these events differentially impacted rich and poor households we also show that the earthquakes of 2001 resulted in large reductions in the number of female members who were sent abroad and large increases in hours of domestic labor supplied by female members we argue that this result is a consequence of subsistence motives because female labor supply at home increased despite lower remuneration

do women shy away from competition do men compete too much we examine whether men and women of the same ability differ in their selection into a competitive environment participants in a laboratory experiment solve a real task first under a noncompetitive piece rate and then a competitive tournament incentive scheme although there are no gender differences in performance men select the tournament twice as much as women when choosing their compensation scheme for the next performance while 73 percent of the men select the tournament only 35 percent of the women make this choice this gender gap in tournament entry is not explained by performance and factors such as risk and feedback aversion only playa negligible role instead the tournament entry gap is driven by men being more overconfident and by gender differences in preferences for performing in a competition the result is that women shy away from competition and men embrace it

location and the multinational enterprise a neglected factor this article first traces the changing world economic scenario for international business over the past two decades and then goes on to examine its implications for the location of foreign direct investment and multinational enterprise activity it suggests that many of the explanations of the 1970s and early 1980s need to be modified as firm specific assets have become mobile across natural boundaries a final section of the article examines the dynamic interface between the value added activities of multinational enterprises in different locations

the ces utility function non linear budget constraints and labour supply results on female participation and hours the most recent efforts in the study of labour supply decisions have concentrated on the estimation of explicit utility indices as a means to overcome the specification and endogeneity problems created by non linear budget constraints the presence of non convexities and the interest in making welfare comparisons between individuals are additional reasons that make the use of explicit utility functions in either direct or indirect form an essential requirement for labour supply studies it is therefore important to consider carefully the available possibilities from a utility index we want flexibility and ease of estimation the stonegeary function has proved its relative worth in consumption studies but its performance has been disappointing when leisure is incorporated into the set of commodities abbot and ashenfelter i976 found that for part of their sample estimated available time was less than hours worked and these results have pervasively reappeared in subsequent studies using this function hausman i980 has recently proposed a utility function which yields a linear hours function this is an important contribution which facilitates the task of estimation enormously this paper argues that the ces utility function despite not generating a linear hours function is also very convenient for estimation purposes in fact it is shown below that to estimate the parameters of the utility function there is no need whatsoever for any explicit hours function labour supply responses by married women have been previously estimated with british data but none of the available results has taken full account of the joint decision on participation and hours and of the non linear shape of the budget constraint that the tax system generates layard et al i980 consider the joint decision in their estimation procedure but ignore the tax system greenhalgh i980 takes into account the non linearity of the budget constraint but estimates labour supply responses by a method which treats participation and hours of work as separate and independent decisions in the present paper on the other hand using an explicit utility index we propose an estimation method which takes into account both the tax system and the joint hours participation decision

an evolutionary approach to understanding international business activity the co evolution of mnes and the institutional environment this paper examines the co evolution of mne activities and institutions external and internal to the firm we develop a theoretical framework for this analysis that draws on the more recent writings of douglass north on institutions as a response to complex forms of uncertainty associated with the rise in global economic interconnectedness and of richard nelson on the co evolution of technology and institutions we link historical changes in the character of mne activities to changes in the institutional environment and highlight the scope for firm level creativity and institutional entrepreneurship that may lead to co evolution with the environment we argue that the main drivers for institutional entrepreneurship are now found in the increasing autonomy of mne subsidiaries thus mne agency derives from more decentralized forms of experimentation in international corporate networks which competence creating nodes of new initiatives can co evolve with local institutions unlike most other streams of related literature our approach connects patterns of institutional change in wider business systems with more micro processes of variety generation and experimentation within and across individual firms this form of co evolutionary analysis is increasingly important to understanding the interrelationships between mne activities and public policy

workfare versus transfers in rural india abstract prevailing methods for evaluating workfare schemes are inconsistent with the arguments made for workfare in poor rural economies those arguments emphasize the existence of higher involuntary underemployment among the poor and the fact that the type of work provided by these schemes gives disutility deterring non poor households from participating to include these features the consumption based welfare metric used in past assessments of workfare schemes in underemployed developing countries is generalized to incorporate a welfare loss from casual manual work while allowing the government to independently value the work done for other reasons using data for india s national rural employment guarantee scheme nregs the paper shows that the policy ranking switches in favor of a basic income guarantee big over workfare allowing for a welfare loss from casual manual labor implies a more poor poor targeting performance but this is not sufficient to compensate for the direct welfare loss from the work requirement for plausible parameter values a big dominates nregs for a given total outlay on workfare wages

of tournaments and temptations an analysis of managerial incentives in the mutual fund industry we test the hypothesis that when their compensation is linked to relative performance managers of investment portfolios likely to end up as losers will manipulate fund risk differently than those managing portfolios likely to be winners an empirical investigation of the performance of 334 growth oriented mutual funds during 1976 to 1991 demonstrates that mid year losers tend to increase fund volatility in the latter part of an annual assessment period to a greater extent than mid year winners furthermore we show that this effect became stronger as industry growth and investor awareness of fund performance increased over time

assets subsistence and the supply curve of labor the backward bending supply curve of labor is now accepted as a matter of course by most economists it has no doubt been perplexing to observe that the most commonly employed types of utility functions do not yield such curves under the usual textbook analysis of the problem 1 particular preference maps have been found that generate backward bending curves 2 however they are nonparametric leading to difficulties of estimation and upon closer examination seem to imply counter intuitive results we will show that taking into account the wealth position of an individual on the one hand and survival consideration on the other greatly expands the variety of shapes that can be derived for the supply curve from some simple utility functions the use of a specific simple utility function also implies some severe restrictions on the form the supply curve can take rendering it testable empirical evidence is shown to support the conclusion that the supply curve is monotonic we will also show that the notion that the aggregate supply curve of labor slopes down rests in part on an error of aggregation and that the empirical evidence usually cited in support of the negative slope when correctly interpreted cannot be so construed

de globalization theories predictions and opportunities for international business research de globalization now a distinct possibility would induce a significant qualitative shift in strategies structures and behaviors observable in international business ib coming to terms with this qualitative shift would require ib research to develop a much deeper integration of politics the key driver of de globalization to support such integration this paper introduces two relevant theories of de globalization from political science liberalism and realism both predict de globalization under current conditions but lead to different expectations about the future world economy liberalism suggests a patchwork of economic linkages while realism predicts the emergence of economic blocs around major countries this paper discusses the resulting opportunities in three areas of ib research political strategies and roles of multinational enterprises mnes global value chains and the role of the national context for political strategies and roles there is a need to explore how regular business activities and deliberate political agency of mnes affect the political sustainability of globalization for value chains questions include their future reach and specialization changes in organizational forms and the impact of political considerations on location decisions research opportunities on national contexts relate to their ability to sustain globalization and their connection with economic and military power

labour supply welfare rankings and the measurement of inequality abstract this paper presents an analysis of inequality using utility based measures of welfare derived from different approaches to modelling household labour supplies the almost ideal demand system specification of preferences is selected for the estimation of a neoclassical household model and of individual decision models which incorporate different assumptions concerning the intra household distribution of income using the rosen 1976 tax perception methodology the study also explores the implications of a model which does not constrain time at home to leisure welfare rankings and inequality measures defined on equivalent income are compared for each type of model the analysis uses australian unit record data on 3 352 households drawn from the australian bureau of statistics 1981 82 income and housing sample survey file the results indicate the sensitivity of welfare orderings and inequality measures to the choice of decision model and to the specification of lump sum transfers between family members a comparative study of equivalent incomes and selected money income variables also illustrates the limitations of observed household and individual incomes as welfare indicators for the analysis of inequality and for policy design

taking prices seriously in the measurement of inequality abstract in the measurement of inequality adjustments for differences across households in their demographic composition and in the price regimes they face are usually very simple often nominal expenditure or income is adjusted with an expenditure independent price deflator and a price independent equivalence scale i show that using more flexible expenditure dependent price deflators and price dependent equivalence scales affects the level of and trend in measured family expenditure inequality in canada over 1969 1997 for example standard methods show a significant decrease in inequality between 1969 and 1978 but more flexible methods show a significant increase in inequality over this period

core or periphery the effects of country of origin agglomerations on the within country expansion of mnes we show how the initial subnational entry location of foreign multinational enterprises mnes in china influences their subsequent within country location choices and expansion speed we distinguish between mnes that establish their first subsidiary in co ethnic cores dense agglomerations of other firms from the same country of origin and mnes that locate their first subsidiary in the periphery i e outside of these co ethnic cores to identify co ethnic cores in china we employ a geo visualization methodology which draws the boundaries of cores organically and dynamically over time we contrast our findings with the prevailing approach of using static administrative boundaries for identifying agglomerations our results provide evidence of path dependency in that a entry through subnational locations with strong co ethnic communities is followed by expansion into other locations where co ethnic communities are present and that b entry through co ethnic communities accelerates the pace at which mnes establish additional subsidiaries in china we also find that co ethnic community effects continue to influence within country mne activities over time despite a host of economic institutional and investment developments

global connectedness and local innovation in industrial clusters in today s knowledge economy clusters are a key driver of a country s competitiveness yet a cluster s technological base is now more than ever influenced by constituent firms actions to tap into distant knowledge sources drawing on a social network perspective and distinguishing between horizontal versus vertical organization based linkages we explore the effects of a cluster s connectedness to foreign locations on its innovation performance we show that improvements in horizontal and vertical connectedness both stimulate a cluster s innovation performance but that their relative effects vary across cluster types innovation in knowledge intensive clusters disproportionately benefits from enhancements in their constituent firms horizontal connectedness to foreign knowledge hotspots innovation in labor intensive clusters mostly gains from stronger vertical connections by their firms to central value chain players abroad we discuss the implications of our findings for research on global knowledge sourcing and cluster upgrading

labour supply household production and intra family welfare distribution abstract this paper demonstrates the importance in conceptual and empirical terms of incorporating household production in models of labour supply to avoid misleading results concerning the intra family distribution of income and behavioural responses to economic policy

taxation and the household abstract previous analyses of demand systems and the welfare effects of taxing male and female labour supplies suppress the analysis of household resource allocation by assuming a household utility function to analyse the implications of assuming this is not the case we construct a simple but fairly general model of household resource allocation and use the properties of the equilibrium of this model to characterise the effects of tax policy on individual utilities as determined by the household resource allocation process

the effects of region on the welfare and monetary income of spanish families in this paper we carry out a regional study aimed at measuring the effects of different regions on the welfare and income of spanish families this has in turn allowed us to calculate the inequality in welfare and income that exists between these households the results confirm the relation between welfare and monetary income for those spanish households in which both spouses work furthermore we find that the welfare level in the east and madrid regions is higher than elsewhere with the lowest welfare level being found in the south the comparison between regions allows us to rank them from the lowest to the highest welfare levels with this ranking adopting the order north centre east south and madrid

the sensitivity of an empirical model of married women s hours of work to economic and statistical assumptions this study undertakes a systematic analysis of several theoretic and statistical assumption s used in many empirical models of female labor supply using a singl e data set psid 1975 labor supply data the author is able to replic ate most of the range of estimated income and substitution effects fo und in previous studies in this field he undertakes extensive specif ication tests and finds that most of this range should be rejected du e to statistical and model misspecifications the two most important assumptions appear to be the tobit assumption used to control for sel f selection into the labor force and exogeneity assumptions on the wi fe s wage rate and her labor market experience copyright 1987 by the econometric society

collective labor supply and welfare the paper develops a general collective model of household labor supply in which agents are characterized by their own possibly altruistic preferences and household decisions are only assumed to be pareto efficient an alternative interpretation is that there are two stages in the internal decision process agents first share nonlabor income according to some given sharing rule then each one optimally chooses his or her own labor supply and consumption this setting is shown to generate testable restrictions on labor supplies moreover the observation of labor supply behavior is sufficient for recovering individual preferences and the sharing rule up to a constant finally the traditional tools of welfare analysis can be adapted to the new setting

gender biased redistribution and intra household distribution abstract this paper examines the implications of income redistribution from men to women for the welfare of married women and children we develop a cournot model of a two person household where agents provide market labor and allocate their spending between a private consumption good and goods for children we show that under plausible restrictions on individual preferences small redistributions to married women reduce their welfare this happens because the income redistribution induces men to reduce their own spending on children by more than the amount redistributed a relative increase in women s independent earnings may however improve children s welfare

why are companies offshoring innovation the emerging global race for talent this paper empirically studies determinants of decision by companies to offshore innovation activities it uses survey data from the international offshoring research network project to estimate the impact of managerial intentionality past experience and environmental factors on the probability of offshoring innovation projects the results show that the emerging shortage of highly skilled science and engineering talent in the us and more generally the need to access qualified personnel are important explanatory factors for offshoring innovation decisions moreover contrary to drivers of many other functions labor arbitrage is less important than other forms of cost savings the paper concludes with a discussion of the changing dynamics underlying offshoring of innovation activities suggesting that companies are entering a global race for talent

the local co evolution of firms and governments in the information age the governance structures of the value creating activities of mnes have evolved towards more networked forms that are geographically highly concentrated and involve partnering with diverse actors the experimentation that takes place within these corporate networks has a parallel on the government side where subnational governments and particularly cities as hubs of economic activity have increased their profile and level of cooperative activity we argue that engagement in these partnerships is an essential way in which firms and governments co evolve and create the basis for sustainable economic growth in the information age while the origins of this collaborative form of governance reside in the increasing knowledge intensity of value creation its implications go far beyond mne value creation and capture extending to issues of global governance such as climate change and sustainable development goals we examine the implications of this process of co evolution both in terms of the costs of developing the requisite corporate capabilities as well as the legitimacy of these efforts as part of a deliberative democracy

institutional inequality and tax incidence abstract this paper analyses the effects of taxation when inequality is not innate a theory of institutional inequality is presented which employs a trade model with circular production and the theory of clubs inequality is introduced by constraints on entry into sectors and local groups within sectors individual time is treated as a fixed factor of production and work and leisure are re defined the analysis suggests that when inequality is institutional and government policy does not alter the mechanisms by which institutions translate the distribution of power into the distribution of income a redistribution of income by conventional tax transfer schemes may not always be feasible

mnes as border crossing multi location enterprises the role of discontinuities in geographic space spurred by the classic work of dunning mne location has become the focus of a growing body of research in the field in this paper we argue that international business ib research examining the spatial dimension has serious weaknesses stemming from its traditional assumption of the country as the location unit of analysis while border crossing remains the key research context of ib placing it within a general spatial framework that recognizes both international and subnational spatial heterogeneity opens up vast new vistas for research analyzing mnes as border crossing multi location enterprises allows the researcher to distinguish between discrete border effects and continuous distance effects and undertake a more fine grained analysis of location within such analysis national borders may appear as qualitative discontinuities in space that is points at which spatial heterogeneity changes abruptly however subnational spatial heterogeneity is often the characteristic that drives firm strategy as mnes decide to locate in particular agglomerations and not at random locations within a country the complex firms that ib scholars study typically include multiple units within the same country so that a complete analysis requires considering both subnational distance effects as well as international border effects

a behavioural analysis of the subsistence standard of living subsistence is analysed as an endogenous variable contrary to its conventional exoge nous treatment it is postulated that the subsistence livers perceive their own standard of subsistence direct their earnings behaviour towards attaining maintaining or exceeding this standard and thus reveal the standard through this behaviour the labour supply function of the working poor which displays a forward falling segment at low wages and an upward rising segment at higher wages is hypothesised to offer measures of subsistence and survival standards the concepts are rationalised using sen s concept of freedom of choice and arrow s concept of freedom as flexibility it is argued that at below subsistence living individuals lack freedom of flexibility in choosing their preferences and thus suffer the loss of freedom of choice while subsistence offers a reasonable minimum of this freedom the freedom is completely lost at the lowest survival standard

is knowledge power knowledge flows subsidiary power and rent seeking within mncs in recent years as multinational corporation mnc subsidiaries have become more closely linked to international networks their knowledge intensity has risen and some of their r d has gained a more creative role simultaneously and often connectedly many subsidiaries have acquired considerable strategic independence in all aspects of their operations and therefore are able to exercise considerable intra firm bargaining power to influence the distribution of the firm s resources in this context we suggest that intra mnc knowledge flows are a key determinant of subsidiary bargaining power we argue that subsidiary managers can exploit such power to pursue their own ends such rent seeking behavior is implicit in much of the literature on managerialism but our analysis suggests that such behavior can now occur in headquarters subsidiary and subsidiary subsidiary relations thus subsidiary strategic independence designed to enhance the competitiveness of outputs market knowledge and inputs asset seeking and learning can be corroded when the pursuit of subsidiary objectives encourages rent seeking empirical analysis of a sample of high technology subsidiaries in the uk provides strong support for the theory we examine several avenues whereby the incentives of units within the mnc can be aligned

clustering of economic activities in polycentric urban regions the case of the randstad local contexts are becoming more important as the impact of the process of globalisation on the spatial distribution of economic activities seems to generate not so much processes of homogenisation as of heterogenisation between regions in advanced economies the combination of specialisation and spatial concentration of economic activity in advanced economies has attracted much attention from economists and geographers here we explore at what level of spatial aggregation contemporary tendencies of clustering of economic activities articulate themselves within the archetypal polycentric urban region of the dutch randstad to examine this question we look at profiles of business start ups in the individual cities of the randstad our focus is on business start ups as they respond most directly to the changes taking place in the economic environment and especially those regarding the supply of labour our findings point to the direction of cluster formation at a supraurban level the profiles of business

strengthening food policy through intrahousehold analysis abstract this paper argues that food policy can be strengthened through an improved understanding of how rights responsibilities and resources are allocated among household members the limitations of the standard unitary economic model of intrahousehold allocation are discussed alternative economic models of the household and the data needs they imply are outlined a number of examples are provided as to when intrahousehold resource allocation patterns and processes have proved important for policy project effectiveness finally the cross cutting nature of the intrahousehold approach is emphasized in terms of the potential benefits for policy design promising areas include irrigation and deforestation management labor intensive public works credit the eradication of micronutrient deficiencies and agriculture human fertility linkages

income uncertainty and optimal redistribution 1 introduction redistribution policy under a utilitarian criterion aims to transfer dollars from one group in the population to another if the weighted utility gain to the recipients exceeds the utility cost to the donors under diminishing marginal utility of income part of any exogenous change in one group s income should be shared with the other group for example if taxpaying workers suffer a negative shock to their mean earnings then part of this utility shock should be spread to nonworkers in the form of lower transfer payments and vice versa for the case of a positive shock this article demonstrates the counterintuitive result that under reasonable preference representations a policymaker may respond optimally to a negative utility shock by redistributing income away from the harmed group thus exacerbating the group s utility loss in particular under risk aversion a mean preserving increase in the variance of income typically has an effect on well being analogous to a decrease in mean income 1 it may nevertheless be welfare enhancing to transfer income away from those suffering an increase in income uncertainty even though this policy compounds their welfare loss the main ideas can be demonstrated in a simple framework for illustration the analysis will focus on redistribution from taxpaying workers to nonworkers the central result is that a meanpreserving increase in earnings uncertainty among taxpayers can increase optimal transfer amounts to nonworkers increasing optimal income replacement rates even though the redistribution exacerbates the taxpayers utility loss from the increase in uncertainty 2 model footnote 1 many factors in the economy affect earnings uncertainty even conditional on being employed such as the form of compensation e

executive compensation and tournament theory empirical tests on danish data this article adds to the empirical literature on tournament theory as a theory of executive compensation i test several propositions of tournament models on a rich data set containing information about 2 600 executives in 210 danish firms during a 4 year period i ask are pay differentials between job levels consistent with relative compensation is pay dispersion between levels higher in noisy environments is the dispersion affected by the number of tournament participants is average pay lower in firms with more compressed pay structures does wider pay dispersion enhance firm performance most of the predictions gain support in the data

how much does subnational region matter to foreign subsidiary performance evidence from fortune global 500 corporations investment in china what explains the heterogeneity of foreign subsidiary performance previous studies have emphasized the importance of industry corporate parent and home country effects on the variation of foreign subsidiary performance building on recent international business and economic geography research this study examines the extent to which subnational region effects can also explain such performance variation we empirically decompose the variance of the performance of fortune global 500 corporations subsidiaries in china during 1998 2006 results show that not only are subnational region effects statistically significant in explaining the variation of subsidiary performance but their interactions with industry corporate parent and home country effects are also significant and economically important we further show that subnational region effects tend to be stronger in the period prior to china s wto accession and in the country s less developed subnational regions our findings highlight the importance of considering both the direct and indirect roles of subnational region in shaping firms strategy and performance in international business research

men women and competition an experimental test of behavior this study reports a series of experiments that examine outcomes when agents are able to choose between a payment scheme that rewards based on absolute performance i e piece rate and a scheme that rewards based on relative performance i e a tournament we test for the presence and persistence of gender differences in performance and the rate of entry into the tournament option and whether these differences are sensitive to the structure of the tournament rewards in the winner take all wta condition only the best performer in the tournament for each round received a payment 4 50 in the graduated tournament condition the same payment 4 50 was divided among the first second and third finishers in the tournament in the wta condition men showed significantly lower forecast errors than women in addition a clear sorting effect occurs in the wta condition in early rounds of the wta condition male entrants into the tournament show significantly lower forecast errors than female tournament entrants however the difference disappears over time after controlling for forecasting skill gender did not predict entry into the tournament for the wta condition however lower forecasting skill reduced the probability of entry in the graduated tournament the situation was reversed men entered the tournament at significantly higher rates even after controlling for skill forecasting skill had no impact on the decision to enter the tournament while the average male entrant to the tournament had lower forecast errors than the average female entrant the men entered at much higher rates as a consequence men were much more likely than women to enter the tournament too frequently

economic status of households and labour supply to market and non market activities mdash some results from a poor rural economy assuming a given underlying utility structure for all households we have demonstrated that the differential labour supply behaviour among household categories results owing to the different sets of constraints they face depending on their economic status and asset ownership using the criteria implied by the theoretical model four household gorups are defined the labour supply functions estimated for these four groups support the theoretical result of significantly different supply behaviour the empirical exercise as expected indicates that the labour supply decision of the subsistence group is guided by their need to achieve the minimum level of consumption while the middle income households who do not have enough non labour income to meet their minimum subsistence need tend to work longer hours in market activities than the workers from high income households however market labour supply by high income households is found to be relatively more sensitive to changes in the wage rate the behaviou

functional forms for labor supply and commodity demands with and without quantity restrictions one of the most important current questions in economic analysis is whether or not labor markets clear in the short run to answer this it is necessary to be able to distinguish between restricted and unrestricted behavior by consumers supplying labor this paper investigates the forms of preferences which lie behind linear models of labor supply and derives the functional forms for commodity demands which accompany them both with and without quantity restrictions in the labor market simple linkages between restricted and unrestricted demands are also considered as is the question of perfect aggregation over consumers in the presence of quantity restrictions

global cities and multinational enterprise location strategy we combine the concept of location derived by economic geographers with theories of the multinational enterprise mne and the liability of foreignness developed by international business scholars to examine the factors that propel mnes toward or away from global cities we argue that three distinctive characteristics of global cities global interconnectedness cosmopolitanism and abundance of advanced producer services help mnes overcome the costs of doing business abroad and we identify the contingencies under which these characteristics combine with firm attributes to exert their strongest influence consistent with these arguments our analysis of a large sample of mne location decisions using a multilevel multinomial model suggests not only that mnes have a strong propensity to locate within global cities but also that these choices are associated with a nuanced interplay of firm and subsidiary level factors including investment motives proprietary capabilities and business strategy our study provides important insights for international business scholars by shedding new light on mne location choices and also contributes to our understanding of economic geography by examining the heterogeneous strategies and capabilities of mnes the primary agents of economic globalization that shape the nature of global cities

accessing vs sourcing knowledge a comparative study of r d internationalization between emerging and advanced economy firms research and development r d internationalization is on the rise for advanced economy multinationals amnes as well as emerging economy multinationals emnes we study emne r d internationalization by comparing it to that by amnes in the context of an emerging knowledge intensive industry we find that these two are fundamentally different processes while the internationalization of amnes r d activities can largely be explained in terms of the twin strategies of competence exploitation and competence creation emne r d internationalization is rooted in the firms overall catch up strategy to get on par with industry leaders an in depth comparison of knowledge flows reveals that within amnes headquarters often serves the primary source of knowledge for r d subsidiaries in contrast within emnes headquarters accesses knowledge from r d subsidiaries in advanced economies for innovation catch up within this dichotomy the innovative capabilities of emne headquarters develop more slowly and with greater difficulty than those of amne subsidiaries

knowledge connectivity an agenda for innovation research in international business the innovation driven multinational enterprise mne has dominated international business ib research for several decades now beginning with the award winning research of dunning there have been calls for ib researchers to rediscover the importance of locations recent work has emphasized that firms and locations co evolve with one another as knowledge is transferred and leveraged across space integrating insights from ib and economic geography we propose a research agenda for ib scholarship on spatially dispersed yet connected innovation processes this agenda is premised on the current reality of global value chains in which mobile mnes people and immobile locations factors interact the research perspective suggested recognizes that locations are host to increasingly fine sliced activities whose nature and composition are continuously changed by mne driven innovation processes as today s specialized activities become tomorrow s standardized ones the shifting distribution of global value creation depends on the pattern of international knowledge connectivity

labor supply the family and poverty the s shaped labor supply curve abstract the canonical model of labor supply is extended to account for subsistence needs and a frequently rigid division of labor within families gender various theories that have been put forward are thus reconciled in particular with respect to the distinct work choices of the poor the model predicts negative labor supply elasticities for secondary workers at low wage rates and positive ones at higher rates but near 0 for primary workers at all levels detailed time allocation data of the rural philippines support these conclusions as well as evidence from other studies including of industrialized countries policy implications are briefly discussed

incentive systems in a real effort experiment in the reported experiment different payment schemes are examined on their incentive effects payments based on individual team and relative performance are compared subjects conducted computerized tasks that required substantial effort the results show that individual and team payment induced the same effort levels in team production free riding occurred but it was compensated by many subjects providing more effort than in case of individual pay effort was higher but more variable in tournaments while in case of varying abilities workers with relatively low ability worked very hard and drove up effort of the others finally attitudes towards work and other workers differed strongly between conditions

performance in competitive environments gender differences even though the provision of equal opportunities for men and women has been a priority in many countries large gender differences prevail in competitive high ranking positions suggested explanations include discrimination and differences in preferences and human capital in this paper we present experimental evidence in support of an additional factor women may be less effective than men in competitive environments even if they are able to perform similarly in non competitive environments in a laboratory experiment we observe as we increase the competitiveness of the environment a significant increase in performance for men but not for women this results in a significant gender gap in performance in tournaments while there is no gap when participants are paid according to piece rate this effect is stronger when women have to compete against men than in single sex competitive environments this suggests that women may be able to perform in competitive environments per se

zoom in zoom out geographic scale and multinational activity ib scholars have long studied the multinational enterprise mne and now recognize that its ability to capture value stems from its control of bottleneck assets in contrast economic geographers and regional scientists have largely focused their attention on the locations within which economic and business systems operate in this article we draw on both these literatures we emphasize that the mne s integration of upstream and downstream strategic considerations to maximize its control of bottleneck assets implies an optimal geographic footprint this optimal footprint is typically asymmetric with a spatial scale that varies dramatically across the different activities of the value chain upstream innovation processes are likely to be based on highly local considerations like the availability of specialized resources and collocation advantages in contrast downstream sales and marketing processes are likely to driven by imperatives of high volume and global reach further in the current fast clockspeed business environment the location and nature of bottleneck assets are likely to change rapidly and unpredictably making organizational flexibility a crucial mne capability

fatal fluctuations cyclicality in infant mortality in india this paper investigates the impact of aggregate income shocks on infant mortality in india and investigates likely mechanisms a recent oecd dominated literature reports the provocative finding that mortality at most ages is pro cyclical similar analyses for poorer countries are scarce and both income risk and mortality risk are greater in poor countries this paper uses data and methods designed to avoid some of the specification problems in previous studies and it explores mechanisms and extensions that have not been previously considered it uses individual data on infant mortality for about 150 000 children born in 1970 1997 merged by cohort and state of birth with a state panel containing information on aggregate income identification rests upon comparing the effects of annual deviations in income from trend on the mortality risks of children born at different times to the same mother conditional upon a number of state time varying covariates including rainshocks and state social expenditure rural infant mortality is counter cyclical the elasticity being about 0 33 this is despite the finding that relatively high risk women avert birth or suffer fetal loss in recessions it seems in part related to recessions stimulating distress labor amongst mothers in contrast to the case in richer countries where they discourage labor market participation health care seeking declines in recessions and this appears to be related to the opportunity cost of maternal time disaggregation reveals that the average results are driven by rural households in which the mother is uneducated or had her first birth in teenage and that it is only girls that are at risk boys are protected from income shocks exposure to poor conditions in the fetal and neonatal period appears to have a larger effect on infant mortality than similar exposure in the postneonatal period
