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

understanding innovation an analysis of persistence for spanish manufacturing firms abstract this study focuses on the persistence of innovation in a panel of spanish manufacturing firms for the period 1990 2008 in particular we analyse whether persistence in firms innovation activities over time is the result of previous experience the dynamic capabilities of the firm or industry market related characteristics we find that r d input and innovation output are highly persistent at the firm level after controlling for unobserved heterogeneity and initial conditions and by using a dynamic random effects probit we conclude that there are similar determinants of persistence in r d and innovative activities among external environmental factors market dynamism affects r d and innovation regarding firm specific characteristics size and outsourcing also have a positive impact on both processes past innovative behaviour is clearly more decisive in explaining the current state of r d and innovation activities than external factors or firm level heterogeneity

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

unemployment persistence is there evidence for stigma effects we present evidence for a highly significant interaction between state dependence in individual unemployment risk and the business cycle the disadvantage from having been unemployed in the previous period is smaller in times of relatively high unemployment and larger in times of low unemployment this is consistent with the existence of stigma effects in the sense that unemployed individuals face difficulties finding a new job because employers interpret unemployment as a negative signal and do so especially when it is easier to find jobs i e when unemployment is low

ethical influences on the evolution of the us tradable permit approach to air pollution control abstract in 1975 a novel approach to air pollution control was implemented in the usa from this rather humble beginning this approach has now been expanded rather dramatically in several different directions this paper describes this evolution shows how the design of the system has been adapted to accommodate ethical concerns and describes how the latest versions of this approach have transformed the regulatory process which spawned the approach in the first place

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

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

incentives for environmental protection this book explores the extent to which pricing incentives such as charges on emissions in contrast to regulatory standards can be shaped into a practical policy that is technically effective politically enactable administratively enforceable and equitable it also compares he advantages and disadvantages of this approach to those that characterize the policy of compliance to regulatory standards and it identifies the criteria on which either pricing mechanisms or regulatory standards should be based three case studies comprise the heart of the book one investigates carcinogenic chemical emissions another audits the tradeoffs in controlling aircraft noise near major airports and the third treats the protection of air quality from pollution by primarily stationary sources the case studies are introduced by a chapter that gives numerous examples of possible pricing approaches and identifies common lessons that the three diverse studies reinforce the studies are followed by a chapter which is based on interviews with congressional staff environmentalists and industrial lobbyists and other interest groups in washington revealing their assessments of pricing mechanisms in environmental protection thomas c schelling and his co authors david harrison jr albert l nichols robert repetto and steven j kelman are all affiliated with the kennedy school of government harvard university the book is fifth in the series regulation of economic activity

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

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

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

simulation estimation of two tiered dynamic panel tobit models with an application to the labour supply of married women a comment summary we find that the empirical results reported in chang journal of applied econometrics 2011 26 5 854 871 are contingent on the specification of the model the use of heckman s initial conditions combined with observed and not latent lagged dependent variables leads to a counter intuitive estimation of the true state dependence the use of wooldridge s initial conditions together with the observed lagged dependent variable and a proper modelling of censoring provides a much more natural estimate of the true state dependence parameters together with a clearer interpretation of the decision to participate in the labour market in the two tiered model copyright 2015 john wiley sons ltd

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

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

myopic loss aversion and stock investments an empirical study of private investors abstract myopic loss aversion was suggested by benartzi and thaler 1995 as an explanation for the equity premium puzzle its main prediction is that loss averse investors who evaluate their investment performance too frequently and therefore often observe small losses on their stock portfolios would invest too little in equity we investigate the link between myopic loss aversion and actual investment decisions of individual investors using survey data our results are consistent with the predictions of benartzi and thaler higher myopic loss aversion is associated with lower stock investment as a share of total assets investors tend to evaluate their stock portfolio performance too often which contributes to the prevalence of myopic loss aversion the effect of myopia is most apparent when investors both evaluate their portfolios frequently and trade stocks regularly

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

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

state dependence individual heterogeneity and the choice of employment status evidence from korea abstractfocusing on the individual heterogeneity this article examines the causes of an individual s employment status choice and the extent of state dependence in the korean labour market we estimate a dynamic multinomial logit model using the panel data drawn from the first to fifteenth wave of the korean labour and income panel study the results suggest the presence of state dependence individual characteristics and growth background have a significant effect on the choice of employment status gender is still an important employment factor males are more likely to be employed and this gender effect is highest for regular employment re one s educational attainment and age operate in opposite directions that is educational attainment age has a positive negative impact on the choice of a regular job and a negative positive impact on the choice of a non regular job contrary to our expectations a wealthy family background reduces the probability of individuals being wage workers and rais

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

trade flows a facet of regionalism or globalisation this paper examines the evidence about the extent of globalisation by focusing on some aspects of international trade flows a reinterpretation of the existing evidence based on the analysis of tables and a range of indicators is provided in the first part of the paper the focus is on whether the increase in trade flows has been predominantly a global or regional phenomenon the analysis points to the tentative conclusion that the dominant tendency is the increase in trade within regional blocs north america the eu and the asia japan blocs rather than across them to address the same question a more formal analysis is undertaken in the second part of the paper by focusing on the relative speed of the convergence in openness within and across regions of the world our results indicate that the degree of openness converges faster across the countries of a given region rather than at the global level reinforcing the conclu sions from the first part of the paper the results are consistent with the view that trade integration is more of a regional phenomenon than a global one

trade flows revisited further evidence on globalisation we consider the relative effects of globalisation and regionalism in the context of recent developments in the world economy we extend and advance the work of chortareas and pelagidis using the recently updated penn world tables data this allows consideration of the recent golden era of globalisation great moderation and the washington consensus we produce evidence that corroborates the findings of chortareas and pelagidis we find however that in the 1990s and in the new millennium globalisation dynamics outpace regionalism nevertheless regionalism displays resilience and in a potential de globalisation context it is more likely to dominate over globalism copyright the author 2011 published by oxford university press on behalf of the cambridge political economy society all rights reserved oxford university press

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

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

domestic and international influences on green taxation economists have made a strong case for the relative efficiency of market based mechanisms for environmental regulation such as cap and trade and green taxes yet the spread of these forms has been limited and traditional command and control regulation still predominates the authors explain geographical and temporal variation in green tax burdens by considering their domestic and international determinants modeling international influences using spatial lags hypotheses are tested using panel data on organisation for economic co operation and development member states from 1995 to 2004 at the domestic level the authors show that green tax burdens are influenced by the left right and environmental positions of legislative medians and the power of the energy producing sector among other factors the authors also show that ideas about policy diffuse through international networks generated by trade and environmental intergovernmental organizations but they do not find compelling evidence for intern

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

the interrelated dynamics of unemployment and low wage employment this paper examines the extent of state dependence in unemployment and the role played in this by intervening low wage employment a range of dynamic random and fixed effects estimators are compared low wage employment is found to have almost as large an adverse effect as unemployment on future prospects and the difference in their effects is found to be insignificant evidence is presented that low wage jobs act as the main conduit for repeat unemployment and considerably increases its probability obtaining a higher wage job reduces the increased risk of repeat unemployment to insignificance

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

multilateralism and the endogenous formation of preferential trade agreements abstract this paper examines the interaction between preferential trade agreements ptas and multilateral tariff reduction in a model of imperfect competition a growing literature finds that the formation of ptas alters the incentives for and the sustainability of multilateral tariff reduction we show that the causation is not one sided multilateral tariff reduction also affects the formation of ptas specifically tariff reduction enhances the incentives to form a pta and increases the likelihood that it is self enforcing thus each round of multilateral tariff reduction should lead to a new wave of ptas this may help to explain the current trend towards regionalism

the myth of economic globalization geographic patterns of commodity trade and foreign direct investment are not consistent with the proposition that european economies are experiencing a process of increasing globalisation internationalisation is taking place as economic integration within the european union during the last 35 years the european union has not become relatively more integrated with the world s other trade blocs moreover in contrast to what globalisation theory might cause us to predict the share in foreign direct investment taken by low wage countries shows little growth we try to explain such findings using arguments about the nature of the process of technological change

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

job search requirements for unemployed at the end of working life effects on unemployment dynamics and self employment probabilities this paper investigates the extent to which job search requirements in unemployment insurance u i increase the probability of self employment as a retirement route for causal identification we apply a difference in differences approach using a dutch 2004 policy reform that introduced job search requirements in u i for persons aged 57 5 and older unemployment dynamics and self employment probabilities are studied using a dynamic multinomial logit model with unobserved heterogeneity the results suggest that job search requirements stimulated people to exit unemployment and discouraged older workers to enter unemployment the probability of self employment as an exit route to retirement increased relative to u i but not relative to paid employment

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

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

charging the earth the promotion of price based measures for pollution control abstract this paper seeks to consider the ways in which the theory and application of economic instruments in particular price based instruments is shaped by the interests values and ideologies of those who are promoting and implementing them although economists have been advocating the use of economic instruments for pollution control for decades it is only in recent years that they have been embraced by business groups and governments looking for a way to avoid stricter and more costly regulations that might inhibit economic growth and as a way of correcting and therefore preserving the free market system this paper examines the rationale for price based instruments and explains how economists have managed to enroll the support of other interest groups even those that have conflicting interests

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

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

selection staging and sequencing in the recent chinese privatization selection in privatization is a decision making process of choosing state owned enterprises soes prioritizing and sequencing privatizing events and determining the extent of private ownership in partial privatization we investigate this process in an important but rarely studied case of china based on the soe population over 1998 2008 we track 49 456 wholly soes and identify 9 359 privatization cases over time our econometric analysis concludes i the privatization selection is a complex decision making process in which local governments balance between various economic financial and political objectives ii in the recent chinese privatization firm performance relates to the selection staging and sequencing in privatization in an inverted u fashion the worse and the best performing soes are more likely to remain state owned maintain higher state holding when privatized and are less likely to be privatized later in time these patterns suggest the privatization reform slowdown and the underlying changes in the privatization policy

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

the necessity for environmental taxes for the avoidance of environmental thievery a note on the paper environmental responsibility versus taxation abstract internalizing environmental costs is a necessary condition for an effective environmental policy since the majority of socio economic activities cannot be free of environmental impacts the noninternalized external environmental costs impose a peculiar thievery of welfare charging environmental costs through environmental taxes and other economic instruments is a necessary condition for avoiding welfare thievery in this context the anti tax approaches emerging within ecological economics are found to be misleading and directing away from an effective environmental policy environmental responsibility is a different issue from the charging of the environmental costs therefore environmental taxes should not be considered as an induction to less environmental responsibility and hence to environmental degradation

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
