co integration analysis of quarterly european tourism demand in tunisia abstract the purpose of this study is to identify the factors that affect the destination choice process in addition to prices and income factors the supply factor is introduced as an explanatory variable in the econometric model co integration analysis and error correction models ecms are used to estimate the long run tourism demand elasticities and to forecast the quarterly european tourism demand for a 1 year ahead horizon the main finding of this study is that the behaviour of european tourists varies from one country to another the co integrating relationships show that the large elasticity magnitude may be the reflection of the relatively expensive services often sought after by tourists from these countries the estimated values of the supply elasticity corroborate the supply induced demand hypothesis finally compared to the basic structural model and using the root mean squared error the ecm provides more precise forecasts

money anticipated changes and policy effectiveness the lucas sargent wallace l s w proposition states that expected policy changes have no influence on real economic variables even in the short run see robert lucas 1972 and thomas sargent and neil wallace 1975 one form of empirical test of the l s w proposition the neutrality proposition began with robert barro s 1977 1978 seminal articles supporting the neutrality proposition however more recent papers including those by david small 1979 john makin 1982 and frederic mishkin 1982a b have reexamined the relationships between anticipated and unanticipated money vs output unemployment and inflation and have found evidence suggesting that anticipated monetary changes do have real effects all of the above cited studies use expectations procedures which estimate for example a money growth equation over the entire period under consideration however this approach assumes that when expectations are being formed at the beginning of the period economic agents have the relevant information for the entire period in this note i reexamine the impact of expected vs unexpected monetary changes focusing on the informational restrictions actually faced by economic agents when formulating expectations the structure of the model used here is similiar to the models of barro and mishkin a measure of real output is assumed to be a function of a policy variable and a vector of predetermined variables the policy variable can be decomposed into anticipated and unanticipated components algebraically

supply side macro economics this paper tests new classical and keynesian explanations of output determination within an encompassing factor utilization model wherein the output decision by producers is modelled as the choice of a utilization rate for employed factors in this encompassing model the ratio of actual to normal output with the latter defined by a nested ces vintage production function with capital energy and employment as factor inputs is explained by unexpected sales a keynesian element abnormal profitability one component of which is the lucas price surprise effect and abnormal inventories results using canadian data show that the keynesian and new classical elements contribute explanatory power as does the production function based measure of normal output while each of these partial models is strongly rejected in favour of the encompassing model the highly structured factor utilization model is also seen to fit better than an unstructured var model u s data confirm the results and show that there are significant effects from abnormal demand profitability and inventory levels even if the labour and capital components of normal output are defined using hours and utilized capital rather than employment and the capital stock the results are also confirmed using alternative output and hence input concepts using a translog function instead of a ces function to define normal output and using data for several other major industrial countries this abstract was borrowed from another version of this item

an econometric investigation of the monetary neutrality and rationality propositions from an international perspective t he combination of the natural rate of unemployment and the rational expectations hypotheses in macroeconomic models results in the now well known conclusion that anticipated short run monetary stabilization policies do not influence real economic variables this policy ineffectiveness proposition has been named the macro rational expectations mre hypothesis by modigliani 1977 as a result the implicit policy prescription is that a price level stabilization policy should be pursued the empirical validity of this conclusion is perhaps the central issue in modern stabilization theory barro 1977 1978 1981 barro and rush 1980 and leiderman 1980 have presented empirical evidence for the united states supporting this proposition however a number of recent studies have claimed that previous empirical results which support the finding that anticipated policy is neutral are flawed corrections of these problems often result in conflicting conclusions see small 1979 gordon 1979 and mishkin 1982 given the important implications of the mre hypothesis it is curious that almost all formal testing has been focused upon the united states while barro has suggested that a cross country study would be useful as far as we know only darby 1980 attempts to test whether anticipated changes in monetary policy are neutral across countries unfortunately his results suffer from problems caused by using generated regressors in addition he makes no attempt to test the individual implications of the mre hypothesis which encompasses the propositions that expectations are rational lad anticipated monetary policy does not matter in this paper we employ the methodology developed by mishkin to test the mre hypothesis in six countries canada germany italy japan the united kingdom and the united states the paper is divided into three major sections and a conclusion section ii briefly reviews mishkin s testing method in section iii the procedure employed to specify the money growth equation is discussed and these equations specified section iv presents and discusses the results of applying the method introduced in section ii in the conclusion the major findings are restated possible limitations discussed and extensions suggested

home country supportiveness unfavorableness and outward foreign direct investment from china what drives the outward foreign direct investments ofdis by emerging market firms emfs drawing on a strategy tripod framework this article proposes a theoretical model to predict ofdi by emfs from china specifically we use institution and industry based views to examine two facets of home country environment namely the supportiveness from home government and unfavorableness from home industry as important determinants of ofdi and compare the relative strength of these effects further we use the resource based view to argue that the effect of the home country environment is contingent on the international experience portfolios of emfs

cliometrics and time series econometrics some theory and applications the paper discusses a range of modern time series methods that have become popular in the past 20 years and considers their usefulness for cliometrics research both in theory and via a range of applications issues such as spurious regression unit roots cointegration persistence causality structural time series methods including time varying parameter models are introduced as are the estimation and testing implications that they involve applications include a discussion of the timing and potential causes of the british industrial revolution income convergence and the long run behaviour of english real wages 1264 1913 finally some new and potentially useful developments are discussed including the mildly explosive processes graphical modelling and long memory

growth and the external constraint lessons from the spanish case the present article attempts to determine the role played by the balance of payments constraint on economic growth in spain 1960 94 using cointegration techniques this empirical exercise also serves to reveal some shortcomings in the usual procedures for estimating thirlwall s law in particular the spanish case reveals how important it is to introduce a variable that expresses the competitiveness gains generated by improvements in quality of the goods and services into the export function it also demonstrates the inadequate simplification entailed in an a priori exclusion of relative prices in external equilibrium equation not taking these two aspects into consideration may give rise to an erroneous confirmation of thirlwall s law especially if as in the spanish case both effects offset each other finally if the aim is to analyse long term relationships between variables it would seem advisable to use procedures such as cointegration with variables in levels

wage stickiness and the non neutrality of money a cross industry analysis abstract the paper provides an empirical test of sticky wage models of business fluctuations by focusing on industry level cross sectional implications that emerge this breaks the observational equivalence existing at the aggregate level between rational expectations long term contracting and imperfect information models the specific implication tested is whether output responses to nominal disturbances industry phillips curve slopes are inversely related to wage indexation elasticities the phillips curve slopes are found to vary across industries for the canadian economy but bear no relationship to indexation elasticities casting doubt on the role of nominal wage rigidity in generating the observed non neutrality of money

money and output in latin america some tests of a rational expectations approach abstract this paper deals with the relationship between money and output in sixteen latin american countries making use of the framework of analysis elaborated by robert barro for the united states three closely interrelated hypotheses are tested 1 that the growth of the money supply is predictable in that it differs from a random walk with trend 2 that only the part of money growth which is not predicted will affect real output in the short run and 3 that as lucas has argued the slope of the phillips curve is smaller in size for countries where money and prices are less predictable

structural analysis of cointegrating vars this survey uses a number of recent developments in the analysis of cointegrating vector autoregressions vars to examine their links to the older structural modelling traditions using autoregressive distributed lag ardl and simultaneous equations models sems in particular it emphasizes the importance of using judgement and economic theory to supplement the statistical information after a brief historical review it sets out the statistical framework discusses the identification of impulse responses using the generalized impulse response functions reviews the analysis of cointegrating vars and highlights the large number of choices applied workers have to make in determining a specification in particular it considers the problem of specification of intercepts and trends and the size of the var in more detail and examines the advantages of the use of exogenous variables in cointegration analysis the issues are illustrated with a small u s macroeconomic model

energy consumption real income and temporal causality results from a multi country study based on cointegration and error correction modelling techniques abstract unlike previous studies on the causal relationship between energy consumption and economic growth this paper illustrates how the finding of cointegration i e long term equilibrium relationship between these variables may be used in testing granger causality based on the most recent johansen s multivariate cointegration tests preceded by various unit root or non stationarity tests we test for cointegration between total energy consumption and real income of six asian economies india pakistan malaysia singapore indonesia and the philippines non rejection of cointegration between variables rules out granger non causality and imples at least one way of granger causality either unidirectional or bidirectionial secondly by using a dynamic vector error correction model we then analyse the direction of granger causation and hence the within sample granger exogeneity or endogeneity of each of the variables thirdly the relative strength of the causality is gauged through the dynamic variance decomposition technique by decomposing the total impact of an unanticipated shock to each of the variables beyond the sample period into proportions attributable to shocks in the other variables including its own in the bivariate system results based on these tools of methodology indicate that while all pair wise relationships shared common univariate integrational properties only relationships for three countries india pakistan and indonesia were cointegrated for these countries temporal causality results were mixed with unidirectional causality from energy to income for india exactly the reverse for indonesia and mutual causality for pakistan the vdcs were not inconsistent with these results and provided us with an additional insight as to the relatively more dominant direction of causation in pakistan simple bivariate vector autoregressive models for the three non cointegrated systems did not indicate any direction of causality significantly in either direction

interpreting econometric evidence the behaviour of consumers expenditure in the uk abstract the dynamic models of consumers expenditure proposed by davidson et al 1978 and hendry and von ungern sternberg 1979 are re appraised in the light of hall s 1978 analysis of the empirical implications of the life cycle permanent income hypothesis in particular that the series for consumption should obey a random walk apart from trend in an attempt to reconcile the conflicting findings monte carlo experiments are used to demonstrate that if the davidson et al model were actually correct the hall model would appear to give a good description of the data and would probably not be rejected all the models are re estimated with new data for the uk and these data do reject a modified random walk specification in conclusion we discuss the issue of income exogeneity and comment on questions of model selection and interpretation

unanticipated monetary growth output and the price level in latin america an empirical investigation abstract this paper provides statistical evidence on the response of real output and the price level to movements in unanticipated monetary growth for 16 latin american countries in the context of barro s version of the rational expectations natural rate theory arima p d q modeling of the growth rate of m2 is employed for each country and the residuals of the selected model utilized to estimate the parameters of the real output and price level equations careful attention is devoted to the autocorrelation structure of the residuals of the real output and price level equations the empirical results suggest that generally unanticipated monetary growth has positive effects on real output and negative effects on the price level such patterns however do not exhibit an unambiguous symmetric response

the economics of poverty traps and persistent poverty an asset based approach abstract longitudinal data on household living standards open the way to a deeper analysis of the nature and extent of poverty while a number of studies have exploited this type of data to distinguish transitory from more chronic forms of income or expenditure poverty this paper develops an asset based approach to poverty analysis that makes it possible to distinguish deep rooted persistent structural poverty from poverty that passes naturally with time due to systemic growth processes drawing on the economic theory of poverty traps and bifurcated accumulation strategies this paper briefly discusses some feasible estimation strategies for empirically identifying poverty traps and long term persistent structural poverty as well as relevant extensions of the popular foster greer thorbecke class of poverty measures the paper closes with reflections on how asset based poverty can be used to underwrite the design of persistent poverty reduction strategies

phasing the operation mode of foreign subsidiaries reaping the benefits of multinationality through internal capital markets the lifetime of foreign equity partnerships is often limited research suggests that mncs abandon their local partners when the need for sharing ownership in foreign subsidiaries has diminished this study shows that mncs may abandon their local equity partners to reap the benefits of multinationality as mncs gain a competitive advantage from leveraging resources across borders they will initially benefit from sharing ownership with a local firm to embed their foreign subsidiaries in the local environment and access local resources more effectively later they will benefit from taking over the local partner s equity share to better embed their subsidiaries in the parent organization and transfer locally accessed resources to the mnc s other locations moderated mediation regressions provide evidence of such practice in the context of cross border transfers of capital resources this strategy seems to work as a corollary of our model panel regressions suggest that sharing ownership with local firms in a host country with a capital resource advantage is associated with appropriating more capital resources from the local debt market while abandoning these partner firms later is associated with transferring more capital resources from this host country via internal capital markets to other parts of the mnc

internationalisation conceptualising an entrepreneurial process of behaviour in time this paper presents a three stage process of conceptual development in response to the call for a unifying direction for research in the emergent field of international entrepreneurship drawing on classic approaches to internationalisation and importing insight from entrepreneurship as a separate and distinct field of study the paper develops three potential models of internationalisation as a time based process of entrepreneurial behaviour the models evolve from the simple through general to precise levels of conceptualisation research implications are discussed

welfare dynamics in rural kenya and madagascar this paper presents comparative qualitative and quantitative evidence from rural kenya and madagascar in an attempt to untangle the causality behind persistent poverty we find striking differences in welfare dynamics depending on whether one uses total income including stochastic terms and inevitable measurement error or the predictable structural component of income based on a household s asset holdings our results suggest the existence of multiple dynamic asset and structural income equilibria consistent with the poverty traps hypothesis furthermore we find supporting evidence of locally increasing returns to assets and of risk management behaviour consistent with poor households defence of a critical asset threshold through asset smoothing

repatriating knowledge variables influencing the transfer process because of the strategic importance of organizational learning in a global economy the knowledge that repatriates acquire during international assignments is a valuable resource few multinational enterprises however actively harvest this knowledge and little quantitative empirical research on this topic exists to date we propose an original model and propositions that delineate the facilitative and inhibiting factors affecting repatriate knowledge transfer to work units we conclude with suggestions for future research and practical implications

stock watson dynamic ols dols and error correction modelling approaches to estimating long and short run elasticities in a demand function new evidence and methodological implications from an application to the demand for coal in mainland china in this paper robust elasticity estimates of coal demand for china are derived using annual data 1953 92 in so doing we illustrate the use of a powerful yet practically convenient and recently developed modelling procedure devised by stock and watson known as dynamic ols dols who provide evidence based on monte carlo simulations of this estimator being superior in small samples compared to a number of alternative estimators as well as being able not only to accommodate higher orders of integration but also to account for possible simultaneity within regressors of a potential demand system furthermore cointegration and error correction methods are employed to derive short run price and income elasticities estimated results are quite robust not only in terms of statistical prowess but also in terms of economic intuition and indicate that over the long run both price and income elasticities are close to unity while short run price and income elasticities are less in absolute value than their long run counterparts there seems to be some divergence in short run parameters from a subsample analysis overall results seem to imply that for china coal consumption should remain relatively constant as future modernization strategies for economic development are pursued in addition the study has clear methodological implications for estimating the long and short run elasticities in a demand function in general and in a wide variety of fields in future applied research

modeling monetary trends in italy using historical data the demand for broad money 1861 1990 in this paper we estimate a stable demand for money relationship for italy using a long series of historical data we extend previously available data sets to obtain a sample for the years 1861 to 1990 and use cointegration analysis and two stage estimation procedures to obtain a dynamic model for m2 demand by employing a small number of explanatory variables and a nonlinear error correction model we find a stable demand for money relationship our model incorporates significant inflation and interest rate effects in contrast to previous studies of this type

a critique of the proposed tests of the natural rate rational expectations hypothesis the failure of the governments of most industrialised countries over the past decade to deal successfully with the problems of rising unemployment and high and often accelerating rates of price and wage inflation has revived interest in the pre keynesian macro economics of sound money and has renewed the controversy of the 1930 s over what governments should or should not do if they wish to achieve full employment with reasonable price stability in democratic societies keynesian economics has come under attack both by those who primarily oppose interventionist policies on ideological grounds and by the so called new classical macro economists who adhere to the natural rate of unemployment hypothesis nrh advanced by phelps i967 and friedman i 968 and the hypothesis of rational formation of expectations reh originally due to muth i96i armed with this joint natural rate rational expectations nr re hypothesis the new classical macro economists have argued that in a world capable of being represented by linear or log linear relations with a unique and stable equilibrium and no information discrepancy between the government and the private sector no government macro economic policy whether monetary or fiscal no matter how ingeniously formulated and how effectively implemented can have any systematic or lasting impact upon the level of output or the rate of unemployment 2 clearly this fundamental policy

inference in cointegrating models uk m1 revisited the paper addresses the practical determination of cointegration rank this is difficult for many reasons deterministic terms play a crucial role in limiting distributions and systems may not be formulated to ensure similarity to nuisance parameters finite sample critical values may differ from asymptotic equivalents dummy variables alter critical values often greatly multiple cointegration vectors must be identified to allow inference the data may be 1 2 rather than 1 1 altering distributions and conditioning must be done with care these issues are illustrated by an empirical application of multivariate cointegration analysis to a small model of narrow money prices output and interest rates in the uk copyright 1998 by blackwell publishers ltd

learning across geographic space pro market reforms multinationalization strategy and profitability building on economic geography and knowledge based theory i argue that pro market reforms augment the profitability of firms by increasing their competitiveness and market knowledge however i propose that this effect is greater for firms that operate internationally firms that operate in more advanced markets and firms that become multinationals before reforms are implemented this is because such firms acquire market knowledge abroad that they can use when responding to reforms at home giving them a head start advantage over other local firms the analyses of a panel of the largest 500 latin american companies from 1989 to 2008 provide support for these arguments

seasonal integration and cointegration modelling labour demand in finnish manufacturing the unifying framework proposed by hylleberg et al 1990 for testing and modelling seasonally integrated and cointegrated variable is introduced these methods are applied to a seasonal manufacturing labour demand model for the years 1970 1 1986 4 seasonal integration and cointegration are established for the variables at the different seasonal frequencies the estimated error correction model indicates that the high frequency components of the models adjust more strongly towards equilibrium states than the lower frequency components

monetary economic myth and econometric reality few of the main macro economic forecasting systems can produce sensible forecasts without the tender loving care of their proprietors many econometric equations in com mon use show significant deterioration in the accuracy with which they characterise data as time passes and many economists are sceptical about empirical evidence feeling it lacks credibility monetary relationships have the dubious distinction of being among the leaders in this field as witnessed by the very large mispredictions of m1 models in the usa over what is now known as the missing money period 1973 76 as well as during the recent great velocity decline 1979 82 in the uk models of m1 and m3 demand experienced large structural breaks following the competition and credit control regu lation changes and the move to floating exchange rates perhaps it is no surprise that goodhart s law should have been formulated with respect to money demand equations

unit root and cointegration tests timeseries versus panel estimates for international health expenditure models classical regression estimates of the determinants of the oecd health expenditures are useful for policy formulation and evaluation however if the underlying timeseries data are not collectively stationary in levels the estimated parameters are faulty and can misguide health policy until very recently the crucial stationarity tests were ignored in a large number of studies on international comparisons stationarity adf phillips perron ips heterogeneous panel and cointegration engle granger bivariate johansen s multivariate tests are conducted here using 1960 1997 health expenditures data 1998 cd rom of 19 oecd countries it is found that extending the time series data length affects the order of integration and number of cointegrating vectors however it is arguable whether the order of integration decreases or increases as more observations are added for testing the failure of the johansen and engle granger cointegration tests for most of the oecd countries cautions policy makers against

deterministic and stochastic trends in the time series models a guide for the applied economist applied economists working with time series data face a dilemma in selecting between models with deterministic and stochastic trends while models with deterministic trends are widely used models with stochastic trends are not so well known in an influential paper harvey 1997 strongly advocates a structural time series approach with stochastic trends in place of the widely used autoregressive models based on unit root tests and cointegration techniques therefore it is important to understand their relative merits this article suggests that both methodologies are useful and they may perform differently in different models this article provides a few guidelines to the applied economists to understand these alternative methods

applied econometrics without sinning one must offer a cautious welcome to any paper kennedy 2001 discussing the problems confronting the implementation of econometrics to empirical data especially from someone who has written an elementary econometrics textbook see kennedy 1985 and later editions there is a considerable gulf between the elementary and inappropriate methodology inherent in many such textbooks and what applied econometricians need to do in practice to model economic data there is some good advice in his paper but also some which is bad kennedy fails to formalize the issues is unclear at key points and neither draws essential distinctions nor defines central terms consequently although some of his recommendations should help to narrow the theory applications gap others could exacerbate the difficulties the remainder of this note amplifies these comments first the topic is in fact addressed in some textbooks albeit none of which are cited by kennedy see inter alia hendry and doornik 2001 and earlier editions especially chs 11 and 15 hendry 1995a provides extensive analyses of the problems of matching theory and evidence empirical modelling and data measurement issues as well as de emphasizing estimation and highlighting the role of graphs spanos 1986 analyzes the difficulties inherent in the conventional paradigm and clearly explains an alternative approach now exposited in his introductory textbook spanos 1999 and charemza and deadman 1997 describe the practice of modelling non stationary time series also see hendry and wallis 1984 ch 1 for an earlier general discussion there are too many relevant papers on methodology to list additional to those kennedy mentions but mizon 1995 and hendry 1997 clarify some of his difficulties second the theory and practice of model building has advanced spectacularly in the last few years see e g hoover and perez 1999 2000 krolzig and hendry 2001 hendry and krolzig 2001b many of the so called sins turn out to be false accusations while others formulating and checking the ingredients of the basic specification remain essential if anything useful is to result from empirical modelling thus considerable revision of the ten econometric commandments

the long run stability of the demand for money italy 1861 1996 this paper examines the stability of the demand for money in italy using a newly extended data set for the period 1861 1996 we examine how the evolution of the financial system in italy and policy shifts have affected the behavior of the long run demand for money and present tests of structural stability we find the demand for broad money to be remarkably stable despite periods of considerable economic turbulence in addition we present evidence on the monetary transmission mechanism our results shed light on attempts to model long run relationships in other countries such as the uk and the us

a survey of some recent econometric methods this survey is written mainly for the applied economist though we hope that the specialist econometrician will find something of interest too our aim has been to try to bring the applied worker as up to date as possible and in the process to improve the quality of applied work by providing access to the latest ideas in econometrics we have tried to describe and explain in a relatively non technical way the main developments that have taken place in the last ten years partly for reasons of space the survey is by no means exhaustive but it does cover a wide range of topics in both time series and cross section analysis among the subjects covered are the followoing the nature of data including integrated and fractionally integrated data four estimation methods maximum likelihood method of moments m estimators and non parametric estimation inference with stationary and integrated regressors a comparison of various model evaluation principles the formulation of models including dynamic specification cointegration and conditional expectations in mean and variance copyright 1989 by royal economic society

cointegration and unit roots this paper provides an updated survey of a burgeoning literature on testing estimation and model specification in the presence of integrated variables integrated variables are a specific class of non stationary variables which seem to characterise faithfully the properties of many macroeconomic time series the analysis of cointegration develops out of the existence of unit roots and offers a generic route to test the validity of the equilibrium predictions of economic theories special emphasis is put on the empirical researcher s point of view

arch models properties estimation and testing abstract the aim of this survey paper is to provide an account of some of the important developments in the autoregressive conditional heteroskedasticity arch model since its inception in a seminal paper by engle 1982 this model takes account of many observed properties of asset prices and therefore various interpretations can be attributed to it we start with the basic arch models and discuss their different interpretations arch models have been generalized in different directions to accommodate more and more features of the real world we provide a comprehensive treatment of many of the extensions of the original arch model next we discuss estimation and testing for arch models and note that these models lead to some interesting and unique problems there have been numerous applications and we mention some of these as we present different models the paper includes a glossary of the acronyms for the models we describe

missing women and the price of tea in china the effect of sex specific earnings on sex imbalance economists have long argued that the sex imbalance in developing countries is caused by underlying economic conditions this paper uses exogenous increases in sex specific agricultural income caused by post mao reforms in china to estimate the effects of total income and sex specific income on sex differential survival of children increasing female income holding male income constant improves survival rates for girls whereas increasing male income holding female income constant worsens survival rates for girls increasing female income increases educational attainment of all children whereas increasing male income decreases educational attainment for girls and has no effect on boys educational attainment

the seasonal unit root structure in new zealand macroeconomic variables adf unit root tests are generally applied to macroeconomic data prior to testing theoritical models to ensure that all relevant variables are integrated of the same order not only is it important to test that these variables are integrated of the same order but also that a cointegrating relationship exists failure to do so raise the specture of false inference associated with the spurious regression problem the seasonal nature of quarterly data adds a further proplem which has generally been overcome by seasonally adjusting the data using procedure such as the census x 11 rather than suppressing it have attempted to determine whether the seasonal component in each variable exhibits stochastic non stationary this paper analysisunit roots in a seasonal setting and compares the recently developed tests for seasonal unit roots as well as the standard augmented dickey fuller zerop frequency unit root tests of the variables tested relatively few paper to be integrated at the seasonal frequenciues and as

evidence on the determinants of canadian provincial government health expenditures 1965 1991 abstract real per capita provincial government expenditures on health care over the period 1965 1991 are examined using pooled time series cross section regression analysis key determinants of real per capita provincial government expenditures on health care over the period 1965 1991 are real provincial per capita income the proportion of the provincial population over age 65 and real provincial per capita federal transfer revenues established program financing had a negative and significant impact on real per capita provincial government health expenditures in newfoundland and quebec an income elasticity of 0 77 implies that health care is not a luxury good

internationalization tacit knowledge and the top management teams of mncs this study investigates the effects of several dimensions of internationalization on the behavior of mncs top management teams the effects include top executives personal presence in foreign markets their participation in meetings about international strategic issues and their tacit knowledge of the firms international business activities

joint titling in rural peru impact on women s participation in household decision making summary peru has implemented joint property rights between spouses and cohabitants on 57 of 1 5 million formalized agricultural plots bargaining theory indicates such redistribution of assets should empower women this project measures influence on decision making in 1 280 rural households interviewing man and woman separately a historical coincidence during the land reform of the 1960 70s made only some communities eligible for plot titling the process was exogenous and independent of both household and community characteristics the significantly positive impact on female empowerment in simple mean comparison and econometric models including pre titling historic variables is hence unbiased

the role of expatriates in the management of interdependence complexity and risk in multinational corporations a multilevel analysis of environmental country and organizational affiliate factors is used to explain the differential utilization rates of u s nationals in overseas professional positions of a major u s bank with 84 branches in 43 countries the research suggests that to the extent that the affiliates of a multinational corporation operate in environments with differing levels of political risk cultural distance and competition and have operations with different levels of complexity and interdependence a single staffing policy may be inappropriate

exploring poverty traps and social exclusion in south africa using qualitative and quantitative data abstract recent theoretical work hypothesises that a polarised society like south africa will suffer a legacy of ineffective social capital and blocked pathways of upward mobility that leaves large numbers of people trapped in poverty to explore these ideas this paper employs a mix of quantitative and qualitative methods novel econometric analysis of asset dynamics over the 1993 98 period identifies a dynamic asset poverty threshold that signals that large numbers of south africans are indeed trapped without a pathway out of poverty qualitative analysis of this period and the period 1998 2001 more deeply examines patterns of mobility and confirms the continuation of this pattern of limited upward mobility and a low level poverty trap in addition the qualitative data permit a closer look at the specific role played by social relationships while finding ample evidence of active social capital and networks these are more helpful for non poor households for the poor social capital at best helps sta

monetary anticipation and the demand for money in the u k testing rationality in the shock absorber hypothesis the carr darby shock absorber hypothesis that unanticipated changes in the money supply cause changes in real balances but anticipated changes have a unit impact on the price level and therefore leave real balances unchanged is tested using two step and joint estimation techniques for the u k two step methods appear to support the shock absorber hypothesis but the superior joint estimation technique decisively rejects the hypothesis particularly the implicit rational expectations cross equation restrictions

an analysis of the disaggregated manufacturing exports of the asian nies to eec usa and japan this paper examines the export performance of the four asian newly industrialized economics nies by modelling their bilateral export flows to three main oecd blocks the usa japan and the european community our estimated export demand models reveal interesting asymmetries between these three areas of destination which do not emerge from previous aggregate empirical studies of nie export performance

the impact of group based credit programs on poor households in bangladesh does the gender of participants matter this paper estimates the impact of participation by gender in the grameen bank and two other group based micro credit programs in bangladesh on labor supply schooling household expenditure and assets the empirical method uses a quasi experimental survey design to correct for the bias from unobserved individual and village level heterogeneity we find that program credit has a larger effect on the behavior of poor households in bangladesh when women are the program participants for example annual household consumption expenditure increases 18 taka for every 100 additional taka borrowed by women from these credit programs compared with 11 taka for men

one kind of freedom poverty dynamics in post apartheid south africa abstract a 1993 south african living standards survey documented the legacy of apartheid in the form high levels of inequality and human insecurity drawing on a 1998 re survey of households in the 1993 study this paper explores whether this legacy has been superseded or whether apartheid s end has been only one kind of freedom that has left households in a poverty trap from which they cannot escape after proposing a theoretically grounded dynamic poverty typology that distinguishes stochastic from structural poverty transitions the paper goes on to estimate that significant numbers of the south african poor are potentially trapped in a structural poverty trap and lack the means to escape poverty over time

the policy ineffectiveness proposition some further tests abstract this study investigates for denmark the relative merits of the new classical versus the monetarist hypotheses regarding the role of monetary policy in stabilizing real economic activity the results do not reject the monetarist contention that anticipated systematic monetary policy has a significant effect on real output in the short run a finding that is inconsistent with the new classical policy ineffectiveness proposition

sinning in the basement what are the rules the ten commandments of applied econometrics unpleasant realities of real world data force applied econometricians to violate the prescriptions of econometric theory as taught by our textbooks leamer 1978 vividly describes this behavior as wanton sinning in the basement with sinners metamorphizing into high priests as they ascend to the third floor to teach econometric theory but this sinning is not completely wanton applied econometricians do or should follow some unwritten rules of behavior in effect bounding the sinning and promoting a brand of honor among sinners this paper exposits these rules and culls from them an unauthorized list of the ten commandments of applied econometrics

shocks and their consequences across and within households in rural zimbabwe abstract increasing attention is now being paid to poverty dynamics in developing countries this work links the extent to which households smooth consumption or smooth assets given income shocks the empirical evidence on the churning of households in and out of poverty and the possibility that temporary shocks can have permanent consequences using longitudinal data from rural zimbabwe this paper extends the discussion of these issues by disaggregating the impact of shocks by levels of asset holdings by disaggregating the impact of shocks on individual level welfare and by assessing the extent to which such shocks have permanent consequences by doing so it assesses the validity of distinguishing between asset and consumption smoothing and provides insights into whether poverty dynamics assessed at the household level provide an adequate picture of dynamics at the individual level

a seasonal model of consumption in this paper the authors present strong empirical evidence that the long run income elasticity of u k nondurable consumers expenditure and its short run rate of adjustment both vary across seasons such variability in the behavior of consumers is consistent with the hypotheses that consumers have seasonal preferences and that they exhibit seasonally varying degrees of habit persistence the tests are based on a modified form of the error correction methodology that allows for seasonally varying slope coefficients simulations for the dynamic responses of the authors model illustrate the important policy implications of these results coauthors are r c bladen hovell a p l chui denise r osborn and j p smith copyright 1989 by royal economic society

cointegration and dynamic time series models abstract this paper provides a survey of some of the recent developments in the field of econometric modelling with cointegrated time series in particular we describe the testing and estimation procedures which have become increasingly popular in the recent applied literature in addition to the two stage procedure proposed by engle and granger we consider extensions to the modelling of dynamic models with cointegrated variables such as the estimation of models with multiple cointegration vectors simultaneous systems models with seasonally integrated and cointegrated variables furthermore we illustrate the practical application of the techniques describes in the paper by means of a tutorial data set

cointegration and stock prices the random walk on wall street revisited abstract one of the more famous and empirically regular instances of unit roots occurs in stock price series where they are consistent with rational expectations and efficient markets under certain assumptions in this paper we investigate the dynamic behavior of five stock prices over the volatile period from january 1972 through december 1979 finding that the series are cointegrated with one dominant common trend a component with an estimated root of 0 95 in addition we find a lesser trend and two complex roots in the cycle model these findings are validated by out of sample forecasts beginning in january 1980 in addition to mean squared error criteria the forecasts are evaluated nonparametrically in two separate applications of a test due to henriksson and merton

the impact of shocks on gender differentiated asset dynamics in bangladesh abstractthis study investigates changes in assets owned by the household head his spouse or jointly in response to shocks in rural agricultural households in bangladesh with household survey panel data looking at changes within households over time we find that weather shocks adversely affect the asset holdings of household heads relatively strongly while predicted negative shocks more strongly lead to assets of both spouses being drawn down the results furthermore suggest that jointly owned assets are not easily sold in response to shocks and that women s asset holdings and coping strategies are shaped by their lower involvement in agriculture

the influence of the management team s international experience on the internationalization behaviors of smes why are some small and medium sized enterprises smes more successful in selling outside their domestic markets than are other smes in the same industry although the traditional explanation is that firms can gain valuable knowledge and resources as they become older and larger small and young firms are not necessarily disadvantaged if they develop other mechanisms to acquire the requisite knowledge and resources we examine the role of the management team s international experience as such a mechanism for the internationalization of canadian software product firms we show that internationally experienced management teams have a greater propensity to develop foreign strategic partners and to delay less in obtaining foreign sales after start up and that these behaviors are associated with a higher degree of internationalization

when do international human capital enhancing practices benefit the bottom line an ability motivation and opportunity perspective we study the conditions under which firms can capitalize on their international human capital ihc using the ability motivation opportunity amo perspective we conceptualize ihc as ability collaborative climate as motivation and the firm s level of internationalization as opportunity we test three alternative amo models the additive model main effect the combinative model two way interactions and the multiplicative model a three way interaction using a cross industry sample of south korean firms we find support for the multiplicative model specifically the relationship between ihc enhancement practices and firm performance is significant and positive only when both collaborative climate and internationalization are high

assets and poverty traps in rural bangladesh using longitudinal survey from rural bangladesh this article examines the determinants of land and asset accumulation over time and explores why some households may be trapped in asset poverty non parametric and parametric methods are used to discern the shape of the asset accumulation path and whether unique or multiple equilibria exist we find evidence for concavity of the dynamic asset frontier but no evidence for multiple equilibria it is suggested that the existence of well functioning factor markets in rural bangladesh and elsewhere in south asia explain the contrasts between our results and those for several african countries
