tariff effects on mnc decisions to engage in intra firm and arm s length trade using confidential firm level data from the bureau of economic analysis bea on activities of u s multinational corporations mncs and their canadian affiliates we study the dramatic growth of intra firm and arm s length u s canada trade over the 1984 95 period we find that decisions to engage in intra firm and arm s length trade are essentially unrelated to tariff and transport cost reductions over this sample period thus we find that the increase in trade occurred almost entirely on the intensive rather than the extensive margin this is consistent with case study evidence in keane and feinberg 2006 where mnc executives consistently indicate that the modest tariff reductions of the 1984 95 period were not sufficient to justify fixed costs of overhauling international supply chains our results have important implications for recent influential models of international trade that rely on sensitivity of intra firm trade to tariffs at the extensive margin to explain how small tariff declines could have led to the explosion of intra firm trade since the 1980s we also find that initial conditions i e 1983 tariffs are uncorrelated with whether firms engaged in intra firm or arm s length trade activity at the start of the sample period this result is surprising as it implies that firms industries with a greater propensity to engage in trade were not in general successful at lobbying for more favourable tariff treatment a l aide de donnees confidentielles au niveau de la firme du bureau of economic analysis bea a propos des activites des firmes plurinationales fpn americaines et de leurs succursales canadiennes on etudie la croissance dramatique du commerce usa canada tant intra firme qu a bout de bras pour la periode 1984 95 il appert que les decisions de s engager dans l un et l autre commerce sont fondamentalement non reliees aux reductions des couts de transport et des tarifs au cours de cette periode on decouvre que l accroissement du commerce s est produit presqu entierement a la marge intensive plutot qu a la marge extensive c est en ligne avec les resultats de l etude de cas de keane et feinberg 2006 ou les cadres des fpn ont systematiquement indique que les modestes reductions de tarifs entre 1984 et 1995 n etaient pas suffisantes pour justifier les couts fixes impliques par la modification de leurs chaines de production internationales ces resultats ont des implications importantes pour certains modeles influents de commerce international qui sont ancres dans une sensibilite du commerce intra firme aux tarifs a la marge extensive pour expliquer comment de faibles chutes de tarifs ont pu engendrer une explosion du commerce intra firme depuis les annees 80 on montre aussi que les conditions initiales e g les tarifs de 1983 ne sont pas co reliees avec le fait que la firme est engagee ou non dans l un ou l autre commerce en debut de periode le resultat est surprenant parce qu il implique que firmes et industries ayant une plus grande propension a commercer n ont pas eu de succes dans leur lobby pour obtenir un traitement tarifaire plus favorable

when is external debt sustainable the article empirically examines the determinants of debt distress defined as periods in which countries resort to any of three forms of exceptional finance significant arrears on external debt paris club rescheduling and non concessional international monetary fund lending probit regressions show that three factors explain a substantial fraction of the cross country and time series variation in the incidence of debt distress the debt burden the quality of policies and institutions and shocks the relative importance of these factors varies with the level of development these results are robust to a variety of alternative specifications and the core specifications have substantial out of sample predictive power the quantitative implications of these results are examined for the lending strategies of official creditors

entry into pharmaceutical submarkets a bayesian panel probit analysis summary we study entry into pharmaceutical submarkets by using a dynamic panel probit model we develop a bayesian version of wooldridge s approach to dealing with unobserved heterogeneity we distinguish between greenfield entry entry with first product and undifferentiated entry which may take the form of introducing further products we extend the standard reduced form model to consider company size in the submarket and across all submarkets we find that greenfield and undifferentiated entries have different determinants that global and submarket size measures have different effects and that sunk costs often have positive effects on entry due to a commitment mechanism copyright 2012 john wiley sons ltd

entrepreneurship start up costs and employment abstract we study the effects of business start up costs on employment in a model with managers workers and matching we show that higher start up costs discourage entrepreneurs and increase the fraction of the population who become workers job creation suffers and employment settles at a lower level we illustrate with evidence from major oecd economies where large variations in start up costs are correlated with large variations in employment levels

the decoupling of farm programs revisiting the wealth effect recent reforms of agricultural policies in developed countries have introduced direct payments as replacements for traditional production enhancing instruments whereas these new instruments can in principle influence production through several channels current empirical studies show no significant impact on production direct payments mainly increase land values in this article we revisit the evaluation of the coupling effects passing through the wealth of agricultural households the initial wealth of these agents while mainly being in the form of land asset holding is always assumed to be fixed to the contrary we show theoretically and through an empirical simulation exercise that once the impact of farm programs on initial wealth is properly accounted for the measure of the coupling effects is not as negligible as found in previous studies copyright 2010 oxford university press

being good when being international in an emerging economy the case of china the importance imposed on corporate social responsibility csr is greater in developed economies than in emerging markets the pressures from various stakeholder groups on the csr are expected to have substantial spillover impact on companies domiciled in emerging economies that obtain revenues from companies in developed economies based on the data from 1 330 listed companies in china the largest emerging economy in the world this study provides evidence that the csr performance of china firms is positively related to the degree of their internationalization and such a positive association is less pronounced for state owned enterprises our findings support the hypothesis that internationalized companies in emerging economies are motivated to improve their csr practices to address concerns from their importers or outsourcers in developed economies

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

state dependence and heterogeneity in health using a bias corrected fixed effects estimator this paper considers the estimation of a dynamic ordered probit of self assessed health status with two fixed effects one in the linear index equation and one in the cut points the two fixed effects allow us to robustly control for heterogeneity in unobserved health status and in reporting behaviour even though we can not separate both sources of heterogeneity the contributions of this paper are twofold first it contributes to the literature that studies the determinants and dynamics of self assessed health measures second this paper contributes to the recent literature on bias correction in nonlinear panel data models with fixed effects by applying and studying the finite sample properties of two of the existing proposals to our model the most direct and easily applicable correction to our model is not the best one and has important biases in our sample sizes

adoption of organic farming in germany and austria an integrative dynamic investment perspective farm level adaptation to changing economic environments is often slower than expected technological innovations for instance are frequently adopted at a later date than the net present value of investment suggests this can be explained by a model of investment under uncertainty which consistently accounts for uncertainty sunk costs and the flexibility of investment timing its essential conclusion is that due to temporal opportunity costs critical incremental cash flows that trigger investments might be higher than those needed for simple cost recovery this accounts for an ostensible reluctance to invest economic hysteresis in this article we demonstrate how slow conversion to organic farming in general and the different rates of conversion in germany and austria in particular can be explained by the new investment theory

the british low wage sector and the employment prospects of the unemployed abstractare low wages a way for the unemployed to switch to higher paying jobs using data from the british household panel survey the labour market dynamics of unemployed low paid and higher paid employed men are analysed moreover the respective un employment duration and occupational skill level are accounted for results show that in general low wages significantly reduce the risk of future unemployment and increase the chances of ascending the salary ladder especially in the case of long term unemployment 360 days furthermore the occupational skill level has a substantial influence on the upward mobility of low paid jobs individuals working in the initial period in a low paid and higher skilled occupation have on average an 11 percentage points higher probability of entering higher pay compared to when working in a low paid and low skilled occupation

does confucianism reduce minority shareholder expropriation evidence from china using a sample of 12 061 firm year observations from the chinese stock market for the period of 2001 2011 and geographic proximity based confucianism variables this study provides strong evidence that confucianism is significantly negatively associated with minority shareholder expropriation implying that confucianism does mitigate agency conflicts between the controlling shareholder and minority shareholders this finding suggests that confucianism has important influence on business ethics and thus can serve as an important ethical philosophy or social norm to mitigate the controlling shareholder s unethical expropriation behavior moreover my findings reveal that the nature of the ultimate owner attenuates the negative association between confucianism and minority shareholder expropriation suggesting that confucianism s negative impact on minority shareholder expropriation is less pronounced for state owned enterprises than for non state owned enterprises the above results are robust to a variety of sensitivity tests and my findings are valid after controlling for the potential endogeneity between confucianism and minority shareholder expropriation

measuring state dependence in individual poverty histories when there is feedback to employment status and household composition this paper argues that the assumption of strict exogeneity which is usually invoked in estimating models of state dependence with unobserved heterogeneity is violated in the poverty context as important variables determining contemporaneous poverty status in particular employment status and household composition are likely to be influenced by past poverty outcomes therefore a model of state dependence is developed that explicitly allows for possible feedback effects from past poverty to future employment and household composition outcomes empirical results based on data from the german socio economic panel gsoep suggest that there are indeed such feedback effects and that failure to take them into account may lead to biased estimates of the state dependence effect copyright 2009 john wiley sons ltd

a theory of shortage in socialist economies based on the soft budget constraint this paper attributes shortages of goods in socialist economies to the soft financial constraints that firms in such economies face a soft budget constraint problem arises when the state bank is unable to make a credible commitment not to refinance bad projects once some investment costs are sunk in such a situation if a consumer good is also demanded by firms as an input and the seller cannot separate firms from households the high market clearing price would lead to welfare losses because too many bad projects would start and crowd out household consumption copyright 1994 by american economic association

good jobs versus bad jobs this article develops a model of noncompetitive labor markets in which high wage good and low wage bad jobs coexist minimum wages and unemployment benefits shift the composition of employment toward high wage jobs because the composition of jobs in the laissez faire equilibrium is inefficiently biased toward low wage jobs these labor market regulations increase average labor productivity and may improve welfare

cross sectional efficiency and labour hoarding in a matching model of unemployment we study positive and normative aspects of steady state equilibrium in a market where firms of endogenous size experience idiosyncratic shocks and undergo a costly search process to hire their workers the stylized model we propose highlights interactions between job security provisions and sectoral shocks in determining the natural rate of unemployment the allocation of labour and the extent of labour hoarding and rationalizes cross sectional asymmetries of gross employment flows at the firm level in our model where productivity and search costs are dynamically heterogeneous across firms decentralized wage bargains imply important cross sectional inefficiencies which overshadow the static search inefficiencies on which simpler models focus

simple solutions to the initial conditions problem in dynamic nonlinear panel data models with unobserved heterogeneity i study a simple widely applicable approach to handling the initial conditions problem in dynamic nonlinear unobserved effects models rather than attempting to obtain the joint distribution of all outcomes of the endogenous variables i propose finding the distribution conditional on the initial value and the observed history of strictly exogenous explanatory variables the approach is flexible and results in simple estimation strategies for at least three leading dynamic nonlinear models probit tobit and poisson regression i treat the general problem of estimating average partial effects and show that simple estimators exist for important special cases copyright 2005 john wiley sons ltd

policy burdens accountability and the soft budget constraint in a socialist economy when a state owned enterprise soe incurs losses the government often provides it with additional funding cuts its taxes and offers other compensations coincidentally the managers of an soe also expect to receive financial assistance from the state such a phenomenon is called the soft budget constraint sbc a term coined by janos kornai 1986 kornai attributes many problems in a socialist economy to the existence of the sbc to achieve successful reform of both the soe s and socialist economies it is imperative to eliminate the sbc however the sbc phenomenon continues to exist in transitional economies even after soe s are privatized world bank 1996 p 45 there is a large literature on the sbc mathias dewatripont et al 1996 and eric maskin 1996 provide surveys on the recent literature according to kornai 1998 there are two types of explanations for the existence of the sbc the exogenous and endogenous explanations of the first type attribute the existence of the sbc to various exogenous reasons including the paternalism of a socialist state and the government s aims for job creation or for gaining political support kornai 1986 explanations of the second type view the sbc as an endogenous phenomenon arising from a time inconsistency problem dewatripont and maskin 1995 for an inefficient uncompleted investment project the state or creditor may have incentives to refinance the investment because the marginal benefit of refinancing exceeds the marginal cost of abandoning it yingyi qian 1994 attributed the shortage of goods in socialist economies to the sbc based on such a timeinconsistency argument in this paper we provide another explanation for the prevalence of the sbc in socialist and transitional economies we will argue that the sbc is rooted in the state s accountability problem the traditional stalinist system was designed to facilitate the establishment of certain strategic soe s which were not viable in a market system to establish the nonviable soe s a socialist government distorted the prices of all kinds of inputs and of outputs and used administrative measures to allocate these inputs and outputs according to plans however due to information and coordination problems the state could make wrong decisions regarding investment production and fail to deliver necessary materials and inputs in time consequently the state instead of soe s was accountable for the failures and needed to allocate additional credits and other assistance to the soe s in order to complete the investment and production as such the sbc arose after the transition to a market economy many strategic firms still remain nonviable in a market economy for strategic purposes the state needs to support these finns moreover most firms in a transitional economy carry many types of policy burdens inherited from the pretransition system lin et al 1998 because the state is accountable for the losses arising from policy burdens the sbc phenomenon persists in a market economy the state s attempts to build nonviable industry and the state s policy burdens on enterprises will also lead to sbc

the dynamics of health in the british household panel survey this paper considers the dynamics of a categorical indicator of self assessed health using eight waves 1991 1998 of the british household panel survey bhps our analysis has three focal points the relative contributions of state dependence and heterogeneity in explaining the dynamics of health the existence and consequences of health related sample attrition and the investigation of the effects of measures of socioeconomic status with a particular focus on educational attainment and income to investigate these issues we use dynamic panel ordered probit models there is clear evidence of health related attrition in the data but this does not distort the estimates of state dependence and of the socioeconomic gradient in health the models show strong positive state dependence and heterogeneity accounts for around 30 of the unexplained variation in health copyright 2004 john wiley sons ltd

too many mothers in law abstract developing countries with low tax capacity may rely on predation to finance government functions government predation in turn is often accused of imposing a choking effect on state owned enterprises soes contributing to the latter s poor performance we formalize this choking effect as a problem of inefficient predation that arises from time inconsistency and show that having multiple government bodies supervising the same soe may mitigate this problem our theory provides an efficiency rationale for the chinese style of decentralization before 1978 and challenges the wisdom of china s recent enterprise reform that attempted to consolidate supervisory power

state dependence in the incidence of strikes evidence from canadian contract data using heckman s dynamic probit model abstract this paper considers whether there is state dependence in strike incidence using longitudinal contract data from canada i obtain my estimates using heckman s estimator for dynamic probit models and find that there is no state dependence in strike incidence

employment hours and the welfare effects of intra firm bargaining intra firm bargaining between a multiple worker firm and an individual employee leads to overhiring taking advantage of the decreasing returns to scale in employment the firm can reduce the marginal product by hiring an additional worker thereby reducing the bargaining wage paid to all existing employees we show that this externality is amplified when firms can adjust hours per worker as well as employment hours are too low at the steady state this misallocation of labor leads to sizeable welfare losses our finding is important for economies in which hours adjustment play an important role as it does in many euro area countries

estimation of fractional dependent variables in dynamic panel data models with an application to firm dividend policy fractional dependent variables and models with state dependence arise in many economic applications however estimating models with fractional dependent variables is complicated by the presence of two corner solution outcomes when coupled with a dynamic panel data setting estimating quantities of interest can be quite complex or computationally difficult this article demonstrates a method for estimating fractional response variables which is easy to implement and presents an application of the technique to the determination of firm dividend policy the estimation demonstrates that neglecting dynamics unobserved heterogeneity or the doubly censored nature of the dependent variable can generate misleading conclusions

indivisible labor lotteries and equilibrium abstract this paper considers an economy where labor is indivisible and agents are identical although the discontinuity in labor supply at the individual level disappears as a result of aggregation it is shown that indivisible labor has strong consequences for the aggregate bahavior of the economy it is also shown that optimal allocations involve lotteries over employment and consumption

dynamics of female labour force participation in france abstractthis article formulates and estimates a structural intertemporal model of labour force participation relying on theoretical characterizations derived from an economic model of lifetime behaviour we estimate a dynamic probit model with correlated random effects using longitudinal data to allow for a dynamic structure the model is applied to a panel of married women drawn from the 1997 2002 french labour force surveys in order to represent their participation behaviour it is estimated by maximum simulated likelihood our results show that women s decisions to go out to work are characterized by significant state dependence unobserved heterogeneity and negative serial correlation in the transitory error component in addition we find that the presence of young children in a woman s household reduces her labour participation but unequally according to their age and number as expected educational level has a positive impact on women s participation last a rise in the husband s wage is found

ghg registries participation and performance under the canadian voluntary climate challenge program between 1994 and 2004 the voluntary challenge and registry vcr played an important role in canadian climate change policy in this paper we examine the decision of firms to participate in the vcr the extent of their involvement and then ask if greenhouse gas emissions are related to past vcr participation as an information provision program we find evidence that firms may participate in vcr to signal their environmental responsibility to regulators and to some extent investors but not to consumers we also find that past involvement in the vcr is a strong and significant determinant of current involvement in the registry greenhouse gas emissions reported to the mandatory greenhouse gas reporting program in 2004 however do not appear to be different between vcr reporters and non reporters ghg emissions are observed to be significantly lower among firms that are smaller emit fewer toxic releases use more renewable energy sources are intermediate good producers and are located in quebec ontario and manitoba

indivisible labor and the business cycle abstract a growth model with shocks to technology is studied labor is indivisible so all variability in hours worked is due to fluctuations in the number employed we find that unlike previous equilibrium models of the business cycle this economy displays large fluctuations in hours worked and relatively small fluctuations in productivity this finding is independent of individuals willingness to substitute leisure across time this and other findings are the result of studying and comparing summary statistics describing this economy an economy with divisible labor and post war u s time series

the market for elective surgery joint estimation of supply and demand this paper develops models of the demand for and supply of elective non emergency surgery using a panel of quarterly data for 200 english hospitals over the period 1995 2002 unusually distinct measures of supply outpatients seen and inpatient admissions and demand outpatient referrals and decisions to admit are available for each observation these offer the opportunity to estimate separate empirical models of supply and demand using ordinary least squares ols regression methods however the strong correlation between the residuals of these models suggests some merit in the deployment of seemingly unrelated regression sur methods although both static and dynamic sur estimations leave the results largely qualitatively unchanged sur estimation can have a considerable quantitative effect relative to the ols results for example sur estimation generates a lower elasticity of inpatient demand with respect to waiting time than that obtained via ols the results offer an important justification for more careful econometric modelling of hospital behaviour than has traditionally been employed in the health economics literature

a theory of wages and labor demand with intra firm bargaining and matching frictions this article provides a model of labor market equilibrium with search and within firm strategic bargaining we yield explicit closed form solutions with heterogeneous labor inputs and capital the solution exhibits overemployment we show that higher relative bargaining power for some groups of workers may lead to overemployment relative to other groups with such other groups being underemployed instead if they have a lower relative bargaining power similarly the hold up problem between capitalists and employees does not necessarily lead to underinvestment in physical capital beyond the neo classical analysis firms are the field of several strategic interactions between capital owners and labor between marginal employees and incumbents and more generally between different groups with various bargaining positions within the firm it is usually considered that the bargaining power of workers entails an employment level that is lower than in a competitive labor market and any increase in the bargaining power of workers raises unemployment these results are true for a wide class of models and notably in the now standard framework to analyze unemployment namely search and matching models of pissarides 2000 however stole and zwiebel 1996a 1996b show that the above results are totally changed in the intra firm bargaining model where employees engage in individual wage negotiation with the firm in fact under the assumption that contract incompleteness does not enable either party to commit to future wages and employment decisions they show that intra firm bargaining yields no rent for employees and gives rise to overemployment compared to a competitive labor market the basic idea of stole and zwiebel is that a firm with a diminishing marginal productivity of labor can decrease the bargained wage which increases in the marginal productivity of labor by raising employment in stole and zwiebel s setting firms overemploy strategically up to the point where workers get their reservation wage

testing for choice dynamics in panel data this article applies different approaches to distinguish state dependence from unobserved heterogeneity and serial correlation and hence test for state dependence in consumer brand choices first we apply a simple method proposed by chamberlain which involves lagged exogenous variables only second we also estimate a lagged dependent variable specification proposed by wooldridge third we use the estimation approach suggested by wooldridge to estimate a model with both lagged dependent and exogenous variables to distinguish between the two different sources of choice dynamics state dependence and lagged effects of the exogenous variables our analysis reveals that the best approach is to use models with both lagged dependent and exogenous variables our findings include strong evidence for state dependence in five out of the six product categories studied in this article

persistence of innovation in dutch manufacturing is it spurious this paper studies the persistence of innovation and the dynamics of innovation output in dutch manufacturing using firm data from three waves of the community innovation surveys cis pertaining to the periods 1994 1996 1996 1998 and 1998 2000 we estimate by maximum likelihood a dynamic panel data type 2 tobit model accounting for individual effects and handling the initial conditions problem we find that there is no evidence of true persistence in achieving technological product or process innovations while past shares of innovative sales condition albeit to a small extent current shares of innovative sales

decomposition analysis of debt s impact on china s energy consumption abstract debt can influence the energy consumption of private sectors and public agencies by changing their fiscal budget constraints from 1996 to 2016 china has had rapid debt growth and become the second largest borrower in the world additionally china has been the largest energy consumer since 2009 the impact of debt growth on its energy consumption however is not much addressed in the literature using an extended lmdi model we investigate the impact of china s debt on its energy consumption from 1996 to 2016 in a new way the results show that 1 among the closed set of debt related factors and other conventional variables studied private debt per capita makes the strongest contribution to china s energy consumption and population has a moderate impact on the growth of energy consumption 2 energy efficiency improvement output efficiency of government debt debt structure adjustment and increased tertiary industry share are mitigating forces of energy consumption these results provide a new holistic perspective for the chinese government to formulate synergistic policies of risk control and pollution control

macroeconomic effects of regulation and deregulation in goods and labor markets product and labor market deregulation reduce and redistribute rents leading economic players to adjust to this new distribution it typically comes with distribution and dynamic effects to study these effects we build a macroeconomic model on two central assumptions monopolistic competition in the goods market which determines the size of rents and bargaining in the labor market which determines the distribution of rents product market regulation determines entry costs and the degree of competition labor market regulation determines the bargaining power of workers we show the effects of deregulation we then use our results to discuss the political economy of deregulation and recent macroeconomic evolutions in europe

does entry regulation hinder job creation evidence from the french retail industry are product market and entry regulation key sources of low employment growth in many european countries we investigate this question in the context of the french retail trade industry since 1974 approval by regional zoning boards has been required for the creation or extension of any large retain store in france we exploit a unique database that provides time and region specific variation in boards approval decisions we show that stronger deterrence of entry by the boards increased retailer concentration and slowed down employment growth in france

the dynamics of aid and political rights using cross country panel data we explore the extent to which the variation over time in measures of democracy and political rights can be explained by changes in aid inflows thus providing direct evidence on the impact of innovations in donor policy on the quality of recipient governance we distinguish between the short run and long run effects of changes in aid our results are very different from those based on cross country variation in aid inflows we find evidence of large differences between the effect of aid for political reform and the effect of other types of aid in aggregate these effects also depend on the recipient country s initial level of political development there is no evidence that aid intended for political reform has achieved its objective and in some countries it may be counterproductive however aggregate aid can have a beneficial effect on political rights

work sharing and overtime this paper deals with the employment effects of reduced working time when firms endogenous response of overtime is considered the analysis distinguishes between fixed and profit maximizing levels of output as well as between interior and corner solutions it is shown that under plausible assumptions a reduction in working time is quite likely to be counterproductive as an employment promoting measure i introduction a reduction in working time has been proposed as a method of increasing employment through work sharing such proposals however often seem to build on an oversimplified view of the world where little consideration is given to various possible repercussions most economists therefore seem rather sceptical towards such proposals for more or less critical discussions see e g hart sloane 1979 charpin 1984 brunstad holm 1984 calmfors 1985 hoel 1986 1987 hoel vale 1986 and dreze 1987 none of these papers however takes into account that actual working time will differ from normal working time to the extent that there is overtime work the aim of this paper is to analyse how endogenous responses of overtime may affect the outcome with respect to employment of reducing the normal working time although overtime work currently accounts for only a minor proportion of total working time around three per cent in sweden we believe this to be an important channel since a major reduction in working time will represent a nonmarginal change which is likely to produce significant changes in established practices our results add to the doubts that a reduction in working time increases employment there has been some recent work on the relationship between normal working time and overtime cf hart 1984 fitzroy hart 1985

no money no honey financial versus knowledge and demand constraints on innovation the paper adds to the literature on the barriers to innovation in two ways first we assess comparatively what mostly constrains firms ability to translate investment in innovation activity into new products and processes whether it is mainly finance as most of the literature would suggest or whether it is mostly knowledge and market related aspects second we suggest a method to correct for the sample selection bias that often affects empirical contributions to this scholarship by filtering out firms that are not interested in innovation from those that struggle to engage in it we obtain a relevant sample of potential innovators which allows us to analyse the comparative effect of financial and non financial barriers on innovation success we find that demand side factors particularly concentrated market structure and lack of demand are as important as financial constraints in determining firms innovation failures this evidence redirects attention from financial to non financial barriers by considering traditional demand market structure and regulation factors involved in reduced firm innovation performance the empirical analysis is based on an unbalanced panel of firm level data from four waves of the uk community innovation survey cis between 2002 and 2010 merged with data from the uk business structure database

job vacancy rates in the firm an empirical analysis this paper presents some evidence on the magnitudes and determinants of job vacancy rates in us firms based on data from a survey in 1980 and 1982 the results show low overall vacancy rates but substantial variation across firms occupations industries and local areas local unemployment unionization and employer size have negative effects on vacancy rates while turnover and sales growth have positive effects the results are generally consistent with the predictions of job matching models

do lenders value corporate social responsibility evidence from china drawing on risk mitigation theory this article examines whether the improvement of firms social performance reduces debt financing costs cdfs in china the world s largest emerging market employing both the ordinary least square ols and the two stage instrumental variable regression methods we find that improved corporate social responsibility csr reduces the cdf when firms csr investment is lower than an optimal level however this relationship is reversed after the csr investment exceeds the optimal level firms with extremely low or extremely high csr are subject to a higher cdf the results also suggest that the optimal csr level for small firms is higher than that for large firms this study is the first to document a u shaped relationship between csr and cdf and also the first to investigate this relationship within an emerging market context

whose wages do unions raise a dynamic model of unionism and wage rate determination for young men we estimate the union premium for young men over a period of declining unionization 1980 87 through a procedure which identifies the alternative sources of the endogeneity of union status while we estimate the average increase in wages resulting from union employment to be in excess of 20 we find that the return to unobserved heterogeneity operating through union status is substantial and that the union premium is highly variable we also find that the premium is sensitive to the form of sorting allowed in estimation moreover the data are consistent with comparative advantage sorting our results suggest that the unobserved heterogeneity which positively contributes to the likelihood of union membership is associated with higher wages we are unable however to determine whether this is due to the ability of these workers to extract monopoly rents or whether it reflects the more demanding hiring standards of employers faced by union wages 1998 john wiley sons ltd

employment and allocation effects of reducing the length of the workday the paper analyses the effects of reducing the length of the workday in a situation with classical unemployment owing to a fixed hourly real wage rate the length of the workday is assumed to enter the production functions of the two sectors manufacturing and services differently employment will increase in the manufacturing sector while the employment effect in the service sector is ambiguous it is possible for employment in the service sector to decline so much that total employment also goes down if the workday is shortened in the manufacturing sector alone employment will rise in this sector and decline in the service sector the effect on total employment is ambiguous with a specific case of mixed classical and keynesian unemployment employment in the manufacturing sector will be unaffected by changes in the length of the workday while a reduction in the length of the workday will reduce employment in the service sector if the income elasticity for services is not less than one

semiparametric bayesian inference for dynamic tobit panel data models with unobserved heterogeneity summary this paper develops semiparametric bayesian methods for inference of dynamic tobit panel data models our approach requires that the conditional mean dependence of the unobserved heterogeneity on the initial conditions and the strictly exogenous variables be specified important quantities of economic interest such as the average partial effect and average transition probabilities can be readily obtained as a by product of the markov chain monte carlo run we apply our method to study female labor supply using a panel data set from the national longitudinal survey of youth 1979 copyright 2008 john wiley sons ltd

how much do decoupled payments affect production an instrumental variable approach with panel data how much decoupled payments such as direct payments in the u s affect agricultural production remains an open empirical question with implications for policy using data from multiple years of the census of agriculture we exploit a provision of the 2002 farm act that departed from previous policy by making oilseeds eligible for direct payments thus increasing payments to areas that historically produced more oilseeds our instrumental variable estimates in contrast to ols estimates suggest that changes in payments over the period 2002 to 2007 had little effect on aggregate production at the zip code level copyright 2012 oxford university press

dependency of organic farms on direct payments in selected eu member states today and tomorrow this paper examines the development of the role of government support in the financial situation of organic farms in selected western and eastern european countries contrasting dependency on direct payments with that of conventional farms and assessing the impact of foreseeable changes in the political and economic environment the results show that direct payments play an important role in the financial viability of organic farms in both western and eastern european countries the level of specific support for organic farming is put into perspective as other support payments and market returns contribute larger shares to total farm revenue in all the countries analysed modelling analyses show that support payments will continue to play an important role in the profitability of organic farms in western europe after implementation of the 2003 reform of common agricultural policy in the eu for organic farmers in eastern european countries the importance of support payments increases strongly with eu accession as first pillar payments are introduced and environmental payments are expanded significantly

media bias in china this paper examines whether and how market competition affected the political bias of government owned newspapers in china from 1981 to 2011 we measure media bias based on coverage of government mouthpiece content propaganda relative to commercial content we first find that a reform that forced newspaper exits reduced competition affected media bias by increasing product specialization with some papers focusing on propaganda and others on commercial content second lower level governments produce less biased content and launch commercial newspapers earlier eroding higher level governments political goals third bottom up competition intensifies the politico economic tradeoff leading to product proliferation and less audience exposure to propaganda

phasing out of environmentally harmful subsidies consequences of the 2003 cap reform abstract subsidies linked to production have been classified as environmentally harmful by the oecd a core element of the eu 2003 common agricultural policy cap reform is to decouple income support from production this paper estimates the environmental consequences of this policy reform an agricultural sector model using a modified version of the positive mathematical programming method depicts the complex natural structural and political relationships of austrian farming changes in management measures can be analyzed with respect to their environmental effects by using appropriate indicators simulation results show that the 2003 cap reform will reduce the average cost of production and may improve environmental conditions regarding soil water and greenhouse gases when compared to a scenario without reform thus the new cap is likely to bring about outcomes which the previous reform agenda 2000 promised but did not deliver

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

labor hoarding and the business cycle this paper investigates the sensitivity of solow residual based measures of technology shocks to labor hoarding behavior using a structural model of labor hoarding and the identifying restriction that innovations to technology shocks are orthogonal to innovations in government consumption we estimate the fraction of the variability of the solow residual that is due to technology shocks our results support the view that a significant proportion of movements in the solow residual are artifacts of labor hoarding behavior specifically we estimate that the variance of innovations to technology is roughly 50 percent less than that implied by standard real business cycle models in addition our results suggest that existing real business cycle studies substantially overstate the extent to which technology shocks account for the variability of postwar aggregate u s output

third party intervention and the preservation of bargaining relationships this article uses longitudinal bargaining contract data to examine whether third party dispute resolution procedures improve the health of bargaining relationships and contribute to their preservat

unemployment and hours of work the north atlantic divide revisited i examine the dynamic evolutions of unemployment hours of work and the service share since the war in the united states and europe the theoretical model brings together all three and emphasizes technological growth computations show that the very low unemployment in europe in the 1960s was due to the high productivity growth associated with technological catch up productivity also played a role in the dynamics of hours but a full explanation for the fast rise of service employment and the big fall in aggregate hours needs further research taxation has played a role but results are mixed

does government funding complement or substitute private research funding to universities abstract there is growing political pressure on universities to intensify their interaction with industry and to enlarge their own research funding options in a context characterised by increasing constraints on public spending however whether the successful achievement of such a political desired outcome is consistent with a restriction of government funding is not clear and requires further investigation as a matter of fact there is scant empirical evidence on whether and to what extent government funding affects the external funding options available to universities in particular those related to research and consulting activities by using a set of probit and tobit panel data models estimated on financial data for the whole population of italian university departments engaged in research in the engineering and physical sciences this paper provides evidence that government funding to universities complements funding from research contracts and consulting contributing to increasing universities collaboration with industry and activating knowledge transfer processes

poverty and social exclusion two sides of the same coin or dynamically interrelated processes there is growing interest in the analysis and measurement of social exclusion to complement the static and dynamic literature on income poverty on theoretical grounds social exclusion and income poverty are seen as different processes but with closely interrelated dynamics however our empirical understanding of the way these two processes dynamically interact at the individual level is still very limited to shed some light on the issue we use a dynamic bivariate probit model controlling for unobserved heterogeneity and wooldridge 2005 type initial conditions both the first and second order markov dynamics are examined we estimate the model using the italian sample of the european community household panel echp waves 1 8 and find a sizable extent of state dependence in both poverty and social exclusion moreover there are dynamic cross effects implying that poverty and social exclusion are mutually reinforcing social policies aimed at eradicating poverty and avoiding individuals social

poverty transition and persistence in ethiopia 1994 2004 summary this study analyzes the persistence of poverty in both rural and urban areas in ethiopia during 1994 2004 the key finding is that households move frequently in and out of poverty but the difficulty of exiting from poverty like the chance of avoiding slipping back increases with the time spent in that state and varies considerably between male and female headed households our results imply that it is important to design anti poverty policies both to hinder households from slipping into extreme poverty and to minimize the length of the poverty spell for households once they have fallen into it

the impact of coupled and decoupled government subsidies on off farm labor participation of u s farm operators with the 1996 farm act the united states introduced payments that were designed to be decoupled labor allocation choices are likely to be affected by receipt of payments and income from off farm jobs has been the major source of income for most farm households for sometime this article examines whether the 1996 change has affected the off farm labor participation of farm households we conclude that the observed increase in off farm participation of farm operators who received payments was not the result of the 1996 policy change government payments whether coupled or decoupled have a negative effect on off farm labor participation

will farmers trade profits for stewardship heterogeneous motivations for farm practice selection we investigate the trade off agricultural producers face between profits and stewardly activities when selecting farm practices instead of the profit maximization framework we model producer behavior in an expanded utility framework built on production technology and including two utility components self and social interests the framework introduces inherent heterogeneity and social environmental motivations into farmer behavior based on this model we hypothesize that there are farmers that are willing to forego some profit to engage in stewardly farm practices with an empirical study we provide evidence that some farmers are willing to make this sacrifice results are consistent with the multi utility hypothesis

split panel jackknife estimation of fixed effect models we propose a jackknife for reducing the order of the bias of maximum likelihood estimates of nonlinear dynamic fixed effect panel models in its simplest form the half panel jackknife the estimator is just 2 hat theta bar theta 1 2 where hat theta is the mle from the full panel and bar theta 1 2 is the average of the two half panel mles each using t 2 time periods and all n cross sectional units this estimator eliminates the first order bias of hat theta the order of the bias is further reduced if two partitions of the panel are used for example two half panels and three 1 3 panels and the corresponding mles on further partitioning the panel any order of bias reduction can be achieved the split panel jackknife estimators are asymptotically normal centered at the true value with variance equal to that of the mle under asymptotics where t is allowed to grow slowly with n in analogous fashion the split panel jackknife reduces the bias of the profile likelihood and the bias of marginal effect estimates simulations in fixed effect dynamic discrete choice models with small t show that the split panel jackknife effectively reduces the bias and mean squared error of the mle and yields confidence intervals with much better coverage

real estate collateral value and investment the case of china previous research on the united states and japan finds economically large impacts of changing real estate collateral value on firm investment that amplified the business cycles of those countries working with unique data on land values in 35 major chinese markets and a panel of firms outside the real estate industry we estimate investment equations that yield no evidence of a collateral channel effect further analysis indicates that china s debt is not characterized by the frictions that give rise to collateral channel effects elsewhere essentially financially constrained borrowers appear able credibly to commit to repay debt in china while there is no impact on investment via the collateral channel our results should not be interpreted as implying there will be no negative fallout from a potential real estate bust on the chinese economy there likely would be but through different channels

employment and distributional effects of restricting working time we study the employment and distributional effects of regulating reducing working time in a general equilibrium model with search matching frictions job creation entails fixed costs but existing jobs are subject to diminishing returns we characterize the equilibrium in the de regulated economy where firms and individual workers freely negotiate wages and hours then we consider the effects of a legislation restricting the maximum working time while we let wages respond endogenously employment effects are sensitive to the representation of preferences in our benchmark small reductions in working time starting from the laissez faire equilibrium solution always result in a small increase in the equilibrium employment while larger reductions reduce employment the regulation benefits workers both unemployed and employed even if wages decrease and even in cases where employment falls but reduces profits and output

interactions between cap agricultural and agri environmental subsidies and their effects on the uptake of organic farming we analyze the effects of the interactions that the two pillars of the european union common agricultural policy market support and rural development have on farmers uptake of organic farming practices special attention is given to the 2003 reform which substantially altered the relative importance of the two types of support by decoupling direct agricultural payments from the production of a specific crop in our empirical analysis we study the case of sweden making use of the variation in the timing of farmers decisions regarding participation in support programs we estimate a dynamic non linear unobserved effects probit model to account for unobserved individual heterogeneity and state dependence our results indicate the existence of a negative effect of the market support system in place when organic farming techniques were adopted before the 2003 reform however this effect is reversed by the introduction of decoupling furthermore the effects of support differ between certified and non certified organic production both pillars have significant effects on non certified organic farming whereas certified organic farming is exclusively driven by agro environmental subsidies

borrowing from pui to pay pom multiple borrowing and over indebtedness in rural thailand summary rural financial markets have grown rapidly in asian emerging market economies thus contributing to economic development and the reduction of poverty at the same time however the level of indebtedness of rural households has increased making households more vulnerable to shocks one of the reasons for rising household debt is the ease of borrowing simultaneously from a growing number of lending institutions this paper addresses two major questions first does borrowing from multiple sources increase rural households risk of over indebtedness second do over indebted rural households refinance their outstanding loans through multiple borrowing running the risk of becoming trapped in a debt cycle employing a dynamic random effects bivariate probit model for a unique set of longitudinal household panel data from northeast thailand this study examines the bidirectional relationship between over indebtedness and multiple borrowing to determine to what extent rural households become trapped in debt cycles on the one hand the results indicate that households in northeast thailand take on multiple loans which further increases their risk of becoming over indebted on the other hand our model results do not confirm the widespread notion that over indebted rural households use multiple loans to refinance unpayable debts

farmers adoption of integrated crop protection and organic farming do moral and social concerns matter we investigate empirically the role of moral and social concerns in farmers decision to adopt integrated crop protection ip and organic farming of a survey questionnaire has been sent to 1286 fruit growers and vegetable producers located in the french areas of alpes de haute provence hautes alpes and vaucluse analysis of individual responses n 243 shows that although economic concerns play a strong role a significant number of respondents give high importance to moral and social ones we also examine how these considerations matter according to different crop protection strategies that is conventional farming ip and of using a multinomial logistic regression we find that 1 social concerns e g showing to others one s environmental commitment drive both ip and of adoption 2 moral concerns e g do not feel guilty about one s choices increase the probability of organic farming adoption only and 3 farmers who give high importance to economic concerns e g cutting production costs are less likely to adopt of

environmental regulation and foreign direct investment evidence from south korea abstract this paper studies how environmental regulation shapes the pattern of foreign direct investment fdi and thereby assesses the pollution haven hypothesis conflicting results exist in the case studies examining the most advanced countries partly due to the deterrent effect of clean technology adoptions on industry migration to minimize the clean technology effect we examine the pattern of south korean fdi over 2000 2007 the period that korean firms relied on old production technologies despite facing rapidly strengthened environmental standards a difference in differences type identification strategy circumvents other potential confounders we find strong evidence that polluting industries tend to invest more in countries with laxer environmental regulations in terms of both the amount of investment intensive margin and the number of new foreign affiliates extensive margin a similar finding is obtained when imports are analyzed

a framework for estimating dynamic unobserved effects panel data models with possible feedback to future explanatory variables abstract i show how to construct the likelihood function for the conditional maximum likelihood estimator in dynamic unobserved effects models where not all conditioning variables are strictly exogenous the method for handling the initial conditions problem appears to be novel and offers a flexible relatively simple alternative to existing methods

wage differentials employer size and unemployment the unique equilibrium solution to a game in which a continuum of individual employers choose permanent wage offers and a continuum of workers search by sequentially sampling from the set of offers is characterized wage dispersion is a robust outcome provided that workers search while employed as well as when unemployed the unique nondegenerate equilibrium distribution of wage offers is constructed for three cases 1 identical workers and employers 2 identical employers and an atomless distribution of worker supply prices and 3 identical workers and an atomless distribution of job productivities copyright 1998 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

a dynamic model of soft budget constraint abstract we study the soft budget constraint by dynamic models and conclude that the soft budget constraint originated in the investment activities do not match the profit function and policy burdens will intensify the soft budget constraint

crossing the innovation threshold through mergers and acquisitions firms are resorting more and more to mergers and acquisitions m a to bridge the gap between where they are and where they would like to be in relation to innovation and performance this paper investigates whether involvement in m a triggers distinct patterns of innovative behaviour across firms and whether this effect is conditional on firm size the analysis combines data from four waves of the community innovation survey cis and the business register of dutch manufacturing firms we observe that m as influence the probability that firms will begin innovation activities or persist with them and these effects vary at different points in the firm size distribution in particular by using m a firms are able to persist with the innovation efforts and output over time and this effect is especially strong for large firms for small firms m a help them to cross the innovation threshold increasing the probability of the transition from a non innovator to an active innovator however the m a effect does not mitigate the tendency of small firms to be occasional innovators

employment and hours of work abstract this paper develops a dynamic model of the labor market in which the degree of substitution between employment and hours of work is determined as part of a search equilibrium each firm chooses its demand for working hours and number of vacancies and the earnings profile is determined by nash bargaining the earnings profile is generally nonlinear in hours of work and defines the trade off between employment and hours of work concave production technology induces firms to overemploy and as a result hours of work are below their optimal level the hosios condition is not sufficient for efficiency when there are two industries workers employed by firms with higher recruitment costs work longer and earn more that is good jobs require longer hours of work interestingly technology differentials cannot account for working hours differentials

the development of and prospects for organic farming in the uk abstract the organic sector in the uk is booming with the largest ever wave of farm conversions underway consumer demand is currently growing faster than supply the evidence regarding the factors that have been critical now and in the past in causing producers to establish organic systems is reviewed this review draws on the authors own work as well as that of other researchers in europe and the usa in the second part of the paper we report on a recent study of the factors that prompt organic producers to abandon registered organic production this analysis is based on a survey of producers formerly registered with the soil association who have left the scheme since 1990 finally the paper considers the current policy regime with respect to organic farming the scope for the continued growth of the sector and the debate regarding the design of future policy
