are household portfolios efficient an analysis conditional on housing in this paper we argue that standard tests of portfolio efficiency are biased towards rejection because they neglect the existence of illiquid wealth in the case of household portfolios the most important illiquid asset is housing if housing stock adjustments are costly and therefore infrequent we show how the dynamic optimization problem produces optimal portfolios in periods of no adjustment that are affected by housing price risk through a hedge term when the housing stock is not adjusted we argue that tests for portfolio efficiency of financial asset must then be run conditionally upon housing wealth in our application we use italian household portfolio data from shiw 1998 and time series data on financial asset and housing stock returns to assess whether actual portfolios are efficient we first consider purely financial portfolios and portfolios that also treat the housing stock as another asset we then consider the consequences of treating the housing stock as given and test for efficiency in this framework our empirical results support the view that the presence of illiquid wealth can explain portfolio choice by home owners

proper risk aversion on introduit et on etudie une condition comportementale significative sur les fonctions d utilite pour les richesses qui signifie qu une loterie indesirable ne peut jamais etre rendue desirable par la presence d une loterie indesirable independante

standard risk aversion this paper introduces the concept of standard risk aversion a von neumann morgenstern utility function has standard risk aversion if any risk makes a small reduction in wealth more painful in the sense of an increased reduction in expected utility also makes any undesirable independent risk more painful it is shown that given monotonicity and concavity the combination of decreasing absolute risk aversion and decreasing absolute prudence is necessary and sufficient for standard risk aversion standard risk aversion is shown to imply not only pratt and zeckhauser s proper risk aversion individually undesirable independent risks always being jointly undesirable but also that being forced to face an undesirable risk reduces the optimal investment in a risky security with and independent return similar results are established for the effect of broad class of increases in one risk on the desirability of or optimal investment in a second independent risk

political economic context and sensitivity to equity differences between the united states and the transition economies of central and eastern europe recent labor economics studies suggest that low enterprise productivity in former socialist economies can be corrected by adopting reward systems emphasizing compensation for performance we used t

the impact of regulatory heterogeneity on agri food trade we estimate the impact of regulatory heterogeneity on agri food trade using a gravity analysis that relies on detailed data on non tariff measures ntms collected by the ntm impact project the data cover a broad range of import requirements for agricultural and food products for the eu and nine of its major trade partners we find that trade is significantly reduced when importing countries have stricter maximum residue limits mrls for plant products than exporting countries for most other measures due to their qualitative nature we were unable to infer whether the importer has stricter standards relative to the exporter and we do not find a robust relationship between these measures and trade our findings suggest that at least for some import standards harmonising regulations will increase trade we also conclude that tariff reductions remain an effective means to increase trade even when ntms abound

converging or diverging a comparative analysis of trends in contingent employment practice in europe over a decade this paper makes a unique contribution to the hrm convergence divergence debate by examining whether organisations operating in europe over the 10 year time period preceding 2000 are converging in their adoption of contingent employment practice the susceptibility of contingent employment practice to both convergent and divergent pressures acts as a useful analytical lens data are drawn from organisations operating in germany spain sweden the netherlands and the uk in 1991 2918 organisations 1995 2048 organisations and 2000 1555 organisations the results suggest that convergence is limited by the institutional embeddedness of organisations

wealth and portfolio composition theory and evidence we examine a survey of 6010 u s households and estimate a model for household portfolio allocation we extend the conventional portfolio choice model in order to capture the observed incompleteness of household portfolios we show that the empirical specification of the joint discrete and continuous choice that characterizes household portfolio behavior is a switching regressions model with endogenous switching we go on to examine the impact of taxes on portfolio composition using detailed survey data to calculate precisely the marginal tax rate facing each household finally we estimate wealth elasticities of demand for a range of assets and liabilities

the determinants of household risky asset holdings australian evidence on background risk and other factors we study the portfolio allocation decisions of australian households using the relatively new household income and labour dynamics in australia hilda survey we focus on household allocations to risky financial assets our empirical analysis considers a range of hypothesised determinants of these allocations we find background risk factors posed by labor income uncertainty and health risk are important credit constraints and observed risk preferences play the expected role a positive age gradient is identified for risky asset holdings and home ownership is associated with greater risky asset holdings a unifying theme for many of our empirical findings is the important role played by financial awareness and knowledge in determining risky asset holdings many non stockholding households appear to lack the experience and financial literacy that might enable them to benefit from direct investment in stocks

determinants of world demand for u s corn seeds the role of trade costs the united states is a large net exporter of corn seeds seed trade including corn has been expanding but its determinants are not well understood this paper econometrically investigates the determinants of world demand for u s corn seeds with a detailed analysis of trade costs impeding exports flows to various markets trade costs include costs associated with distance tariffs and sanitary phytosanitary sps regulations imposed by foreign countries on u s corn seed exports sps policy information comes from the excerpt data base of usda aphis the analysis relies on a gravity like model based on an explicit specification of derived demand for seed by foreign corn producers a sps count variable is incorporated as a shifter in the unit cost of seeds faced by foreign users we use data from 48 countries and for the years 1989 to 2004 we find that all trade costs matter and have had a negative impact on u s corn seed exports tariffs matter most followed by sps measures and distance an extensive econometric investigation reveals that qualitative results are robust to specification changes but that sample selection bias is present in log linear specifications based on seed export levels and approximating zero trade data with a small positive number

differences in managerial values a study of u s hong kong and prc managers in this study of convergence divergence of managerial values four western developed measures machiavellianism locus of control intolerance of ambiguity and dogmatism and the four dimensions of the eastern developed chinese value survey confucian dynamism human heartedness integration and moral discipline were the measures used the findings indicate that often times both culture and the business environment interact to create a unique set of managerial values in a country

country and organizational level adaptation to foreign workplace ideologies a comparative study of distributive justice values in china russia and the united states drawing from concepts of cultural distance and cultural propensity to change we predict the convergence divergence or crossvergence of distributive justice values in china and russia as compared with us managers using institutional theory we predict responses by organizational type joint ventures foreign owned vs state owned enterprises soes lastly we develop predictions based on the interaction of culture and organizational type results indicate divergence in china regardless of organizational type in contrast differences by organizational type were observed among russian managers with convergence among managers in joint ventures but continuing divergence among managers in soes implications for theory are discussed

optimal portfolio choice for long horizon investors with nontradable labor income this paper examines how risky labor income and retirement affect optimal portfolio choice with idiosyncratic labor income risk the optimal allocation to stocks is unambiguously larger for employed investors than for retired investors consistent with the typical recommendations of investment advisors increasing idiosyncratic labor income risk raises investors willingness to save and reduces their stock portfolio allocation towards the level of retired investors positive correlation between labor income and stock returns has a further negative effect and can actually reduce stockholdings below the level of retired investors financial advisors typically recommend that their customers invest more in stocks than in safe assets when they are working and to shift their investments towards safe assets when they retire jagannathan and kocherlakota 1996 malkiel 1996 by contrast the standard academic models of portfolio choice merton 1969 1971 samuelson 1969 show that retirement is irrelevant for portfolio decisions if investment opportunities are constant and human capital is tradable in this case the fraction of wealth optimally invested in risky assets should be constant over the lifetime of an individual recent research building on the pioneering work by merton 1971 shows that time varying investment opportunities result in portfolio rules with an intertemporal hedging component whose magnitude depends on the investment horizon of the investor kim and omberg 1996 balduzzi and lynch 1997 brennan schwartz and lagnado 1997 brandt 1999 campbell and viceira 1999 2001 barberis 2000 with time variation in investment opportunities retirement and death play an instrumental role as events that exogenously fix the individual s investment horizon more importantly retirement also marks the time at which individuals stop working and thereafter must live off their lifetime savings and possibly transfers from this perspective retirement matters for portfolio choice

portfolio choice in the presence of background risk in this paper we focus on how the presence of background risks from sources such as labour and entrepreneurial income influences portfolio allocations this interaction is explored in a theoretical model that is calibrated using cross sectional data from a variety of sources the model is shown to be consistent with some but not all aspects of cross sectional observations of portfolio holdings the paper also provides a survey of the extensive theoretical and empirical literature on portfolio choice

the impact of regulations on agricultural trade evidence from the sps and tbt agreements according to world trade organization rules countries may adopt regulations under the agreements on sanitary and phyto sanitary sps and technical barriers to trade tbt we analyze the structure of these measures in agricultural trade the inventory approach suggests that european countries have among the lowest coverage ratios of all oecd countries using a gravity equation we also estimate their stringency our results suggest that they significantly reduce developing countries exports to oecd countries but do not affect trade between oecd members furthermore european imports are more negatively influenced by sps and tbts than imports of other oecd countries

organizational inertia and momentum a dynamic model of strategic change this study provides an empirical test of hannan and freeman s theory of structural inertia we examined the changes organizations undertook in response to a major environmental change in addition

institutional theory and mnc subsidiary hrm practices evidence from a three country study this study sets out to explore human resource management hrm practices in multinational corporation mnc subsidiaries within an institutional theory framework based on a sample of 158 subsidiaries of mncs operating in the united states russia and finland the paper examines factors hypothesised to influence the hrm practices adapted in us japanese and european mnc subsidiaries located in russia finland and the us the results indicate significant differences in hrm practices used across host countries both the status of the subsidiary human resource department and the degree to which the subsidiary was involved in knowledge transfer with other parts of the mnc had a significant impact on the selection of hrm practices

putting risk in its proper place this paper examines preferences toward particular classes of lottery pairs we show how such concepts as prudence and temperance can be fully characterized by a preference relation over these lotteries if preferences are defined in an expected utility framework with differentiable utility the direction of preference for a particular class of lottery pairs is equivalent to signing the nth derivative of the utility function what makes our characterization appealing is its simplicity which seems particularly amenable to experimentation

impacts of free trade agreements on agricultural trade creation and trade diversion this paper evaluates agricultural trade creation and diversion effects of the most important free trade agreements ftas trade creation and diversion effects are estimated using a poisson pseudo maximum likelihood ppml estimator with various fixed effects to deal with heteroskedasticity and zero trade observations the analysis finds that ppml estimation is preferred to ols and the estimated impacts of ftas are different if zero trade observations are considered the asean china preferential trade agreement eu 15 eu 25 and southern african development community agreements have generated large increases in agricultural trade among their members

precautionary saving and subjective earnings variance abstract in this paper i examine a model of precautionary saving and i show that the fact that people may insure against income risk makes it difficult to evaluate the extent of precautionary accumulation by simply looking at the relationship between wealth and earnings variance i also argue that occupations may represent a bad proxy for income risk

crossvergence 10 years on impact and further potential the 1997 jibs paper by ralston holt terpstra and yu was instrumental in anchoring and extending the construct of crossvergence in cross cultural research ten years on the paper has lost none of its relevance and continues to offer important opportunities for further theory development and attendant empirical research scope for further work seems to exist especially in three areas the meaning of crossvergence national culture and economic ideology and processes of change

understanding compensation practice variations across firms the impact of national culture with operations spread worldwide firms that find themselves competing in a global marketplace are looking at the implications of the admonition when in rome this raises the question do cultures of countries have an impact on the generally accepted methods of managing human resources the answer to this question is the focus of this article by developing culture specific propositions for four categories of compensation practices based on status performance social benefits and programs and employee ownership plans we seek to determine the extent to which hofstede s four dimensions of culture are associated with specific compensation practices support is found for most of the propositions the implications of the finding for the management of human resources by multinational firms are discussed

fostering corporate entrepreneurship cross cultural comparisons of the importance of individualism versus collectivism this study reports on results of a cross cultural empirical investigation designed to assess the impact of individualism collectivism upon organizational entrepreneurship the findings indicate individualism collectivism is an important factor in understanding entrepreneurial behavior in the firm implications of these findings are discussed

the importance of business owners in assessing the size of precautionary savings abstract not properly accounting for differences between business owners and nonbusiness owners in studies of household wealth can lead to erroneous conclusions about the significance of different saving motives using data from the panel study of income dynamics from the 1980s and 1990s we show that within samples of both business owners and non business owners the amount of precautionary savings with respect to labor income risk is modest and accounts for less than 10 of total household wealth previous large estimates of the size of precautionary balances resulted from pooling these two groups together such pooling is inappropriate given that business owners face higher labor risk and accumulate more wealth than non business owners for reasons unrelated to precautionary motives

risk management and wealth accumulation behavior in france abstract recent theoretical saving models have placed greater emphasis on studying prudent behavior in the face of an uncertain future and have shown the influences of background risks on precautionary savings a prudent household exposed to a high future income risk will increase its savings empirical tests on recent french data insee patrimoine 97 show the relevance of subjective earnings variance to explain wealth accumulation but its contribution is not very large around 5

the effect of national culture on the choice of entry mode characteristics of national cultures have frequently been claimed to influence the selection of entry modes this article investigates this claim by developing a theoretical argument for why culture should influence the choice of entry two hypotheses are derived which relate culture to entry mode choice one focusing on the cultural distance between countries the other on attitudes towards uncertainty avoidance using a multinomial logit model and controlling for other effects the hypotheses are tested by analysing data on 228 entries into the united states market by acquisition wholly owned greenfield and joint venture empirical support for the effect of national culture on entry choice is found

income risk borrowing constraints and portfolio choice economic theory suggests that uninsurable income risk and the expectation of future borrowing constraints can reduce the share of risky assets in a household s portfolio if the utility function exhibits decreasing absolute risk aversion and decreasing prudence an individual will reduce his exposure to rate of return risks when confronted with other independent risks if there are transaction costs the expectation of future borrowing constraints should induce individuals to keep a lower proportion of their wealth in the form of illiquid and risky assets the authors find support for these propositions in a cross section of italian households copyright 1996 by american economic association

on the future of international joint venture research international joint ventures ijvs are an important type of international strategic alliance isa and have been studied by scholars for decades resulting in a plethora of empirical studies publications and reviews yet an inadequate accumulation of knowledge exists as a closer look reveals much more than providing a summary and critical assessment of past contributions this paper develops an expansive research agenda based upon a deep understanding of past research and comprehensive frameworks that distill this research we identify a number of research opportunities that would not only advance ijv research but also closely related literatures and disciplines such as isas theories of the multinational firm international business research and strategic management

the impact of natural culture and economic ideology on managerial work values a study of the united states russia japan and china this study assesses the impact of economic ideology and national culture on the individual work values of managers in the united states russia japan and china the convergence divergence crossvergence cdc framework was used as theoretical framework for the study while the schwartz value survey svs was used to operationalize over investigation of managerial work values across these four countries the findings largely support the crossvergence prospective while also confirming the role of national culture implications from the findings are drawn for the convergence divergence crossvergence of values as well as for the feasibility of multidomestic or global strategies for a corporate culture

risk management housing and stockholding this article investigates the possible explanations of the stockholding puzzle by focusing on housing and other uninsurable risks associated with income health and business taking the french household wealth survey patrimoine 2004 french national statistical institute we find that the share of financial wealth invested in stocks depends on transaction and information costs risk aversion exposure to real estate risk and to a lesser extent labour market risk these results are obtained by controlling for endogenous home ownership status

efficient portfolios when housing needs change over the life cycle abstract we address the issue of the efficiency of household portfolios in the presence of housing risk we treat housing stock as an asset and rents as a stochastic liability stream over the life cycle households can be short or long in their net housing position efficient financial portfolios are the sum of a standard markowitz portfolio and a housing risk hedge term that multiplies net housing wealth our empirical results show that net housing plays a key role in determining which household portfolios are inefficient the largest proportion of inefficient portfolios obtains among those with positive net housing who should invest more in stocks

do sanitary phytosanitary and quality related standards affect international trade evidence from chilean fruit exports summary increasing awareness of food safety issues has led to intensive use of sanitary phytosanitary and quality related regulations and standards imposing a burden on exporting countries worldwide this study assesses the impact of such regulations and standards estimating a gravity model for chilean fresh fruit exports that incorporates a stringency perception index that comprises different dimensions of trade requirements our results suggest that an increase in stringency has a negative and substantial effect on exported volumes and the reduction is higher if stringency increases in developed countries results also showed that different dimensions have different effects on trade

the impact of sanitary and phytosanitary measures on market entry and trade flows in an attempt to disentangle the impact of sanitary and phytosanitary sps measures on trade patterns we estimate a heckman selection model on the hs4 disaggregated level of trade we find that aggregated sps measures constitute barriers to agricultural and food trade consistently to all exporters but conditional on market entry trade flows are positively affected by sps measures additionally we find that sps measures related to conformity assessment hamper market entry and trade flows while sps measures related to product characteristics pose an entry barrier but increase bilateral trade flows conditional on meeting the standard

culture and congruence the fit between management practices and national culture the financial performance of european and asian work units of one multinational company is examined as a function of the congruence between management practices and national culture using hofstede s five national culture dimensions and analogous management practices we find that work unit financial performance is higher when management practices in the work unit are congruent with the national culture

why do so few hold stocks the authors investigate why 75 percent of u s households do not hold stocks despite the equity premium and predictions of expected utility models the question is relevant for privatization asset pricing and tax progressivity issues they show that risk aversion per se heterogeneity of beliefs habit persistence time nonseparability and quantity constraints on borrowing do not account for the phenomenon a wedge between borrowing and lending rates and minimum investment requirements are plausible but empirically weak factors more promising explanations are inertia and departures from expected utility maximization there is also qualified support for nondiversifiable income risk as a contributing factor copyright 1995 by royal economic society

what differences in the cultural backgrounds of partners are detrimental for international joint ventures an international joint venture implies that a firm has to cooperate with a partner with a different cultural background in this study hypotheses about which differences in national culture are most disruptive for international joint ventures were developed and tested using hofstede s five dimensions the study focused on how these dimensions affect the survival of international joint ventures as well as their incidence relative to wholly owned subsidiaries the hypotheses were tested on longitudinal data about 828 foreign entries of twenty five dutch multinational in seventy two countries between 1966 and 1994 the database which spans almost three decades was also used to provide new evidence on a key assumption of hofstede s work that cultural values are stable over time

attitudes towards large income risk in welfare states an international comparison using survey data and the instrument developed by barsky et al we estimate the distribution of attitudes towards income risk in a country where many employment and health related risks are generously covered by a tax financed social insurance system norway in 2006 under a constant relative risk aversion assumption the sample average for the coefficient of relative risk aversion is 3 8 with standard deviation 2 3 this number is then contrasted to that for five other oecd countries where risk attitudes have been measured using the same instrument and also prior to the financial crisis chile france italy the netherlands and the usa when we relate this distribution for stated relative risk aversion to that for generosity of social insurance and the risks related to employment and health expenditure a picture emerges suggesting that more extensive welfare states induce higher risk tolerance for foreground risks a relationship that is in line with the theory on risk vulnerability

opening the black box of the relationship between hrm practices and firm performance a comparison of mne subsidiaries in the usa finland and russia this paper investigates the extent to which different human resource management hrm practices work better in different countries we also try to open the black box between hrm and multinational enterprise mne subsidiary performance by considering mechanisms through which hrm practices affect mne subsidiary performance the study utilizes a unique data set consisting of subsidiaries of 241 mnes operating in russia usa and finland in the partial least square analysis used to examine our hypotheses we demonstrate that different hrm practices are preferable in different countries and that motivation and ability are important mediating variables in the hrm mne subsidiary performance relationship

owner occupied housing and investment in stocks an empirical test abstract this paper analyzes the empirical link between housing investment and stockholding by testing implications of the model of flavin and yamashita american economic review 92 2002 345 362 their model illustrates how the house to net worth ratio influences a homeowner s portfolio composition regression estimates suggest that there is a strong relationship between housing investment and stockholding and the house to net worth ratio could explain certain heterogeneity in stockholding households with a high house to net worth ratio hold a lower proportion in stocks the results support the hypothesis that overinvestment in housing affects financial portfolio of homeowners

national natural rates of interest and the single monetary policy in the euro area national natural rates of interest and the single monetary policy in the euro area we estimate time varying national natural real rates of interest r for the four largest economies of the euro area over 1999 2016 we further derive the associated national real interest rate gaps which gauge the perceived monetary policy stance in each country we find that the average r have been lower after 2008 furthermore national r were significantly negative in southern countries during the sovereign crisis as their effective real rates soared national rate gaps across the euro area diverged however a common policy stance has been restored since 2014 as the european central bank s unconventional programs gathered pace

empirical evidence on the trade impact of asynchronous regulatory approval of new gmo events abstract this paper focuses on the ex post empirical analysis of the trade impact of asynchronous regulatory approval of new genetically modified organism gmo events we contribute to the literature in three ways first we define indices to assess the extent of asynchronicity and the relative strictness of the gmo approval authorizations of 40 countries considering gmo regulatory developments between 2000 and 2012 regarding cotton maize and soybeans second we introduce indices that are country pair specific product specific and year specific in a gravity model to examine the trade impact of asynchronous regulatory approval across countries by grouping the countries according to the state of their national regulatory gmo frameworks we have an even more differentiated view on the trade impact of asynchronous approval that focuses not only on the existence of regulations but also on their restrictiveness the results from the gravity model show that asynchronous approval has negatively impacted trade flows of cotton maize and soybeans it is observed that both asynchronous approvals and the restrictiveness of importing countries regulations to address the importation of gmo products matter meaning those countries that have already adopted a comprehensive gmo regulatory framework and have policies to manage the importation of gmo crops tend to feel a higher negative impact on trade flows

pay for performance in emerging markets insights from china with the rapid increase in the application of western hr practices in emerging markets it is crucial to investigate how non western employees react to western hr practices such as pay for performance pfp we investigate employee reactions to pfp in emerging markets using china as a case our multilevel analyses based on data from 574 engineers in 22 domestic firms and eight foreign firms in china demonstrated that pfp was positively associated with conscientiousness at the individual level in contrast pfp was negatively related to employees organizational commitment and interpersonal helping at the organization level this study suggests that the impact of culture distance associated with western hr practices may be more likely to manifest itself in the collective entity than at the individual level employees of domestic firms reported significantly higher levels of performance appraisal satisfaction and justice perceptions than employees of foreign firms which might explain why pfp was more widely implemented in domestic firms in china the present results demonstrated that in addition to the culture distance the context distance between domestic and foreign firms may play a critical role in accruing benefits from pfp indicating that pfp can be more beneficial to domestic firms than to foreign firms the present findings provide practical implications for foreign firms operating in emerging markets

protectionism indices for non tariff measures an application to maximum residue levels abstract we propose aggregation indices of non tariff measures ntms to quantify their protectionism relative to international standards of stringency we apply the indices to national maximum residue limit mrl regulations on pesticides and veterinary drugs affecting agricultural and food trade and using a science based criteria embodied in codex alimentarius international standards the approach links two streams of the ntm literature one concerned with the aggregation of various ntms into operational indices for econometric and modeling purposes and the other attempting to evaluate the protectionism of ntms the data used in the application come from a large international dataset on veterinary and pesticide mrls and codex mrl standards for a large set of countries

economic integration and income convergence not such a strong link abstract we would expect that the process of globalization between 1870 and 1914 and subsequent disintegration of the world economy during the interwar period would have led first to income convergence and then to income divergence between the participating countries but in fact we find stronger evidence for income convergence during the interwar period than during the first globalization similarly the average level of import protection in the world cannot be shown to have either helped or hampered convergence the evidence for trade induced convergence is therefore weak

precautionary saving in the small and in the large the theory of precautionary saving is shown to be isomorphic to the arrow pratt theory of risk aversion making possible the application of a large body of knowledge about risk aversion to precautionary saving and more generally to the theory of optimal choice under risk in particular a measure of the strength of the precautionary saving motive analogous to the arrow pratt measure of risk aversion is used to establish a number of new propositions about precautionary saving and to give a new interpretation of the dreze modigliani substitution effect copyright 1990 by the econometric society
