some issues concerning interest rate pegging price level determinacy and the real bills doctrine abstract in a recent paper canzoneri henderson and rogoff have shown that it is possible for the monetary authority to peg the nominal interest rate without creating price level indeterminacy in a simplified version of the 1975 sargent wallace model the present paper begins by reviewing that result which involves a limiting case of a money supply rule that depicts the authority as responding to current values of the interest rate then it shows that there exists an alternative rule that will peg the nominal rate without creating indeterminacy but that this rule induces a different pattern of price level fluctuations next the paper considers whether indeterminacy will prevail if the authority tries to effect a peg in a third way by simply standing ready to buy and sell securities at the desired rate finally the implications of the foregoing results are drawn for arguments concerning the real bills doctrine and some critical comments are directed at the recent attempted rehabilitation of that doctrine by sargent and wallace

import price elasticities reconsidering the evidence recent economic geography and trade empirical studies based on monopolistic competition suggest high levels of trade price elasticities between 3 and 1 1 however price elasticity estimations in trade equations using unit values as price proxies usually lead to lower values of around unity we show that those inconclusive results may be due to some misspecification in these equations as well as measurement errors in prices when suit able instrumental variables are used within a panel of industrialized countries we obtain high price elasticities the majority ranging from i to 13 the highest estimates correspond to industries producing homogeneous goods jel classification c2 c3 and f 1

factor endowments and the international location of production econometric evidence for the oecd 1970 1985 abstract this paper uses data on manufacturing output and factor endowments for 20 oecd countries from 1970 to 1985 to examine the production side of the factor proportions model under well known conditions there will be a linear rybczynski relationship between sectoral outputs and factor endowments across countries this proposition is investigated using the kalman filter and maximum likelihood techniques to estimate time varying parameter models the results indicate that capital and unskilled labor are sources of comparative advantage for most industries while skilled labor is a source of comparative disadvantage residual analysis shows that the neoclassical model has poor explanatory power

demographic change and policy responses implications for the global economy the fertility declines associated with the final phase of the global demographic transition have led to slower population growth and accelerated ageing in developed countries and in several advanced developing countries a global demographic and economic model is used to assess the implications of these changes for population sizes age gender distributions labour force growth and their implications for economic performance a baseline projection that incorporates declining fertility is compared with a hypothetical constant population growth scenario the results show that slower population growth and ageing reduces average saving rates in industrial regions yet global investment demand is also slowed and saving rates rise in developing regions so there is no net tightening of financial markets increased aged labour force participation considered one solution to the resulting rise in aged dependency in advanced regions is found to redistribute investment in favour of the industrialised regions and hence to accelerate their per capita income growth while conferring on the other regions compensatory terms of trade improvements the alternative of replacement migration is found to require inconceivably large population movements it also impairs real per capita growth in destination regions but by least in western europe where the terms of trade are improved by the immigration

intra industry trade in financial services abstract intra industry trade iit has been central to increasing the variety of products available to consumers unlike traditional trade theories the recent trade theories have placed an emphasis on the role of foreign direct investment fdi in generating trade and increasing the volume of iit this study is the first study of intra industry trade in banking services in which the key elements of the new trade theories of iit have been taken into account in measuring the determinants of iit in banking services the empirical results of the determinants of iit in banking services indicate that factor endowments average per capita income fdi in banking economies of scale in the banking sector trade intensity between the us and its partners and market openness make a positive contribution to the volume of iit in banking services furthermore the empirical results indicate that intra trade activities amongst the us multinational corporations reduce the level of iit in banking services for the us

border effects and the availability of domestic products abroad trade between countries could fall short of trade within a country because 1 the volume of international trade is less than the volume of domestic trade for a given product the intensive margin or 2 some goods that are sold domestically are simply not exported the extensive margin my theoretical model illustrates that either of these two factors could explain a given aggregate border effect i examine the empirical relevance of this distinction by isolating the fraction of total domestic production attributable only to exporters finding that around one half of the border effect may be attributed to each explanation jel classification f1 les effets de frontieres et la disponibilite de produits domestiques a l etranger le commerce entre pays peut etre moindre que le commerce a l interieur d un pays parce que 1 le volume de commerce international est moindre que le volume du commerce interieur pour un produit donne la marge intensive ou 2 certains biens qui sont vendus a l interieur d un pays ne sont tout simplement pas exportes la marge extensive un modele theorique montre que l un et l autre de ces facteurs pourraient expliquer un certain effet de frontiere au niveau agrege on montre l importance empirique de cette distinction en isolant la fraction de la production interieure totale attribuable strictement aux exportateurs et il s avere qu a peu pres la moitie de l effet de frontiere est attribuable a chacune des deux explications

money and endogenous growth the ramsey romer model of endogenous growth is extended to allow for holdings of real money balances and government debt as well as capital and for non interconnected generations of households tax financed increases in government consumption and debt depress growth prospects and boost inflation as long as a positive birth rate ensures that future taxes are shouldered by future yet unborn generations debt financed increases in government consumption depress growth and boost inflation even more money financed increases in government consumption depress growth less but increase inflation by more giving subsidies through an increase in monetary growth is non neutral since this increases real growth and thus inflation increases by a lesser amount than monetary growth bond financed increases in monetary growth lead to a larger increase in real growth and a smaller increase in inflation if there are cost adjustment for investment cuts in monetary growth and increases in government debt and government consumption induce an increase in the real interest rate copyright 1994 by ohio state university press

openness to trade in manufactures in the oecd abstract how open are the advanced economies to trade with each other in this paper openness is calculated relative to the predictions of the monopolistic competition trade model using data on manufacturing trade and production in the oecd in 1985 the paper finds that 1 japan imports much less than other large oecd countries while the european countries have larger import volumes than does the us 2 japan and the us engage in less intra industry trade than the rest of the oecd and 3 the eu countries are less open to imports from japan and the us than those countries are open to imports from the eu

approaches to inequality of opportunity principles measures and evidence we put together the dierent conceptual issues involved in measuring inequality of opportunity discuss how these concepts have been translated into computable measures and point out the problems and choices researchers face when implementing these measures our analysis identies and suggests several new possibilities to measure inequality of opportunity the relevance of the conceptual issues and modelling choices are illustrated with ndings from the empirical literature on income inequality of opportunity

a comparison of optimal tax policies when compensation or responsibility matter this paper examines optimal redistribution in a model with high and low skilled individuals with heterogeneous tastes for labor we compare the extent to which optimal policies based on different normative criteria obey the principles of compensation for differential skills and responsibility for preferences for labor when labor supply is along the extensive margin with heterogeneity in skills and preferences traditional welfarist criteria including utilitarianism present unappealing policy recommendations in some scenarios as they fail to take compensation and responsibility issues into account criteria from the social choice literature perform better in this regard in first and second best more importantly these equality of opportunity criteria push the second best policy away from an earned income tax credit and in the direction of a negative income tax

fiscal policy and liquidity traps with heterogeneous agents this paper explores global dynamics in a monetary model with limited asset market participation and the zero lower bound on nominal interest rates it is shown that a rise in government transfers to non ricardian consumers financed by debt based taxes to ricardian consumers is capable of escaping disinflationary paths typically convergent to a liquidity trap fiscal policy does not need to be unsustainable at the low inflation steady state to avoid liquidity traps as argued in the context of the standard single representative agent setup

inequality of opportunity in sub saharan africa in the last decades inequality of opportunity has been extensively studied by economists on the assumption that in addition to being normatively undesirable it can be related to low potential for growth this paper evaluates inequality of opportunity and the different sources of unequal opportunities in 11 sub saharan africa countries the results indicate that the portion of total inequality that can be attributed to exogenous circumstances that is circumstances outside the control of individuals control is between 30 percent and 40 percent in the countries considered the results also indicate a positive association between total consumption inequality and inequality of opportunity finally this paper addresses a number of methodological issues that typically arise when measuring inequality of opportunity with imperfect data which is the typical case in developing countries

trade blocs currency blocs and the reorientation of world trade in the 1930s we analyze the impact of commercial and financial policies on the reorientation of trade in the 1930s we report evidence that commercial policies attenuated prior connections between income growth and trade and that exchange rate instability marginally discouraged international trade in contrast the tendency toward regionalization commonly ascribed to the formation of trade and currency blocs was already evident to a considerable extent prior to the regional policy initiatives of the 1930s this reorientation is more properly attributed to ongoing historical forces such as commercial and financial links between countries forged over many years

china s one belt one road initiative the impact of trade facilitation versus physical infrastructure on exports the one belt one road obor project is perhaps china s most significant international relations initiative in recent times it is based on openness harmony inclusivity mutual benefit and market operations and aims to connect the economically vibrant east asia and the developed europe by land and by sea and in the process it brings growth and development to tens of countries along the modern silk routes in this paper we compare the impact of the main initiatives of obor namely enhancements in physical infrastructure and improvements in border administration on the trade of countries that have signed on to this project especially countries along the six economic corridors we find overwhelming evidence that shows improvements in border administration has the greatest impact on exports of corridor countries although physical infrastructure is important for trade the chinese government should place equal attention to improvements in trade facilitation to ensure trade routes operate seamlessly across the various corridors

fair income tax fairness is a key concept in redistribution issues in this paper we study how particular requirements of fairness can shed light on the design of the optimal income tax schedule we consider a population of heterogeneous individuals or households who differ in two respects first they have unequal skills and therefore unequal earning abilities second they differ in terms of their preferences about consumption and leisure and as a consequence typically make different labour time choices both kinds of differences generate income inequalities we study how to justify and compute a redistribution income tax in this context redistribution through an income tax usually entails distortions of incentives but the resulting efficiency loss has to be weighed against potential improvements in the fairness of the distribution of resources we address this efficiency equity trade off here by constructing social preferences which obey the standard pareto principle in addition to fairness conditions

measures of distributional change an axiomatic approach in recent years a number of interesting papers have appeared in the general field of the analysis of changes in a frequency distribution the most common applications of such analysis are in the areas of income and wealth re distribution and the contributions have usually focussed on a particular specialised issue such as mobility of individuals within a structure or of horizontal inequity as opposed to vertical inequality implicit in the comparison of two distributions a number of approaches to each of these problems have been suggested and indeed several specific practical indices of mobility or inequity have been proposed 1 whilst some of these can be shown to have very useful features in their application it is probably fair to say that most derive from an ad hoc approach to the particular aspect of the problem on which the author had focussed it is interesting to note that comparatively few papers attempt to exploit the similarities involved in each of these issues all this contrasts rather sharply with the state of play in an obviously closely related game that of the measurement of inequality much of the essential foundation of the problem of measuring inequality as we presently understand it seems to be more or less sorted out in a systematic fashion roughly speaking what may be done is as follows given

to each the same and to each his own a proposal to measure responsibility sensitive income inequality this paper deals with the question of how to incorporate modern responsibility catering egalitarianism into economic theory on the measurement of income inequality i present a particular axiomatic expression of the main aspects of such egalitarianism then to measure offensive inequality separately i construct a norm or reference income distribution based upon the axiomatic model to replace the perfectly equal income distribution that is used as norm by all common inequality measures i defend the use of a particular measure of distributional change to determine the degree of offensive inequality and apply the method to belgian income data

equality of opportunity theory and measurement during the last third of the twentieth century political philosophers actively debated about the content of distributive justice the ruling ethical view of utilitarianism was challenged by various versions of equality of opportunities economists formulated several ways of modeling these ideas focusing upon how individuals are placed with respect to opportunities for achieving various outcomes and what compensation is due to individuals with truncated opportunities after presenting a review of the main philosophical ideas section 2 we turn to economic models sections 3 and 4 we propose a reformulation of the definition of economic development replacing the utilitarian measure of gdp per capita with a measure of the degree to which opportunities for income acquisition in a nation have been equalized finally we discuss issues that the econometrician faces in measuring inequality of opportunity briefly review the empirical literature section 6 and conclude section 7

monopolistic competition and international trade reconsidering the evidence we test some propositions about international trade flows that are derived from models of monopolistic competition developed by elhanan helpman and paul krugman we investigate whether the volume of trade between oecd countries is consistent with the predictions of a model in which all trade is intraindustry trade in differentiated products we then repeat the test with non oecd countries we also investigate whether the share of intraindustry trade is consistent with a more general theoretical model in which some but not all trade is intraindustry trade our results lead us to question the apparent empirical success of these models

devaluation levels vs rates and balance of payments in a cash in advance economy abstract this paper investigates the consequences of the currency devaluation both in levels and rates on the balance of payments in a cash in advance economy with finite horizons endogenous capital accumulation and international capital immobility in this context a once and for all currency devaluation induces a balance of payments surplus whereas a sustained increase in the rate of devaluation produces in principle an ambiguous effect on the balance of payments if however non restrictive assumptions on some structural parameters are made an increase in the devaluation rate leads to a balance of payments surplus the exact opposite of calvo s result j int econ 11 2 1981 165

measuring unfair in equality abstract this paper shows one way of generalizing the standard framework of inequality measurement to allow for a distinction between fair and unfair inequalities we introduce the unfairness lorenz curve and the unfairness gini which are generalizations of the standard versions of the lorenz curve and the gini with this more general framework in place we study the implications of responsibility sensitive theories of justice for the evaluation of the income distribution in norway from 1986 to 2005 we find that both the pre tax and the post tax income distributions have become less fair in norway even though the standard gini for the pre tax income distribution has decreased in the same period two trends explain this development the increase in income share of the top percentile and the change in the situation of females in the labor market the concentration of income at the top of the distribution contributes both to increased unfairness and increased inequality whereas the increase in females working hours and level of education primarily contributes to a reduction in inequality thus the latter effect dominates for the standard gini and the former effect for the unfairness gini furthermore we find that the increase in post tax unfairness is even larger than the increase in pre tax unfairness which shows that the tax system in norway contributes less to eliminating unfairness in 2005 than in 1986

measuring long term inequality of opportunity abstract in this paper we introduce a new family of rank dependent measures of inequality and social welfare consistent with the equality of opportunity eop principle the proposed framework can be used to measure long term as well as short term eop depending on whether we let permanent income or snapshots of income form the basis of the analysis furthermore it allows for both an ex ante and an ex post approach to eop there is long term ex post inequality of opportunity if individuals who exert the same effort have different permanent incomes in comparison the ex ante approach focuses on differences in the expected permanent income between groups of individuals with identical circumstances to demonstrate the empirical relevance of a long run perspective on eop we exploit a unique panel data from norway on individuals incomes over their working life span this allows us to examine how well analysis of opportunity inequality based on snapshots of income approximate the results based on permanent income

environmental abatement and intergenerational distribution this paper employs an overlapping generations model to explore the impact of public abatement on private investment and the intergenerational distribution of welfare whereas public abatement benefits old generations in terms of non environmental welfare future generations gain most in terms of environmental welfare the overall benefits tend to be smallest for generations born at the time of the unanticipated policy shock public debt policy however can be employed to ensure that welfare gains are distributed more equally across the various generations such a policy implies that natural capital crowds out man made capital

how trade related are intellectual property rights abstract there is little empirical evidence about whether differing international levels of patent protection influence trade flows if a nation strengthens its patent laws it could experience higher or lower imports we specify an empirical model in which deviations of bilateral sectoral imports from anticipated levels are related to income trade barriers and patent laws patent regulations in the importing country are corrected for endogeneity through the use of instrumental variables the results of the final equations indicate that increasing patent protection has a positive impact on bilateral manufacturing imports into both small and large developing economies

preferences for redistribution in the land of opportunities this paper explores how individual preferences for redistribution depend on future income prospects in addition to estimating the impact of individuals socioeconomic background and of their subjective perceptions of future mobility we employ panel data to construct dobjectivet measures of expected gains and losses from redistribution for different categories of individuals we find that such measures have considerable explanatory power and perform better than dgeneral mobilityt indexes we also find that preferences for redistribution respond to individual beliefs on what determines one s position in the social ladder ceteris paribus people who believe that the american society offers equal opportunities are more averse to redistribution d 2004 published by elsevier b v

lower bounds on inequality of opportunity and measurement error when measuring inequality of opportunity researchers usually opt to eliminate within type variation provided that in practice it is impossible to observe all circumstances this implies that the researcher estimates a lower bound of the true level of inequality of opportunity by using data drawn from 27 demographic household surveys circa 2008 it is found that lower bound estimates can have substantial measurement error and that measurement error can vary considerably across countries as a consequence lower bound estimates of inequality of opportunity can demand too little redistribution to equalize inequalities due to circumstances and can make the traditional cross country comparisons misleading

ex ante inequality of opportunity in health decomposition and distributional analysis of biomarkers abstract we use a set of biomarkers to measure inequality of opportunity iop in the risk of major chronic conditions in the uk applying a direct ex ante iop approach we find that inequalities in biomarkers attributed to circumstances account for a non trivial part of the total variation for example observed circumstances account for 20 of the total inequalities in our composite measure of multi system health risk allostatic load we propose an extension to the decomposition of ex ante iop to complement the mean based approach analysing the contribution of circumstances across the quantiles of the biomarker distributions shapley decompositions show that for most of the biomarkers the percentage contribution of socioeconomic circumstances education and childhood socioeconomic status relative to differences attributable to age and gender increase towards the right tail of the biomarker distribution where health risks are more pronounced

equity responsibility and the cultural dimension we present questionnaire studies concerning equity judgments based on an axiom that underlies rawls s difference principle our investigation spanning over a period of fifteen years was run at german austrian and slovenian universities we also modified two of our basic scenarios to check for responsibility aspects additionally we included information on socio demographic characteristics of respondents in a probit model answers depend on cultural environments but results indicate some convergence over time responsibility considerations are important if they can be attributed to particular persons although overall explanatory power of demographic attributes is low we observe significant gender differences

the volume of trade in differentiated intermediate goods theory and evidence this paper develops a model of trade in differentiated intermediate goods and shows how the structure of the importing country s production will influence gross bilateral import volumes a regression equation directly implied by the model is estimated using disaggregated bilateral trade data for the oecd countries in 1985 the data reject the model a more general model suggested by the theory establishes strong links between a country s factor endowments and its gross trade volume this model is dominated statistically by a fixed effects model and does not substantially alter the conclusions of earlier empirical studies about openness to trade in manufactured goods copyright 1995 by mit press

trade policy issues and empirical analysis interest in u s trade policy has been stimulated in recent years by the massive american trade deficit by the belief that intervention by foreign governments in international markets has given other countries a competitive edge over the united states and by concern about the increase in protectionism among industrial countries in turn major analytical developments in international economics have revolutionized trade theory broadening its scope both by introducing in a more formal manner such concepts as imperfect competition increasing returns product differentiation and learning effects and by including the study of political and economic factors that shape trade policy decisions this collection of papers the result of a conference held by the nber applies these new trade theories to existing world cases and also presents complementary empirical studies that are grounded in more traditional trade theories the volume is divided into four parts the papers in part 1 consider the problem of imperfect competition empirically assessing the economic effect of various trade policies introduced in industries in which the new trade theory seems to apply those in part 2 isolate the effects of protection from the influences of the many economic changes that accompany actual periods of protection and also examine how the effects from exogenous changes in economic conditions vary with the form of protection part 3 provides new empirical evidence on the effect of foreign production by a country s firms on the home country s exports finally in part 4 two key bilateral issues are analyzed recent u s japanese trade tensions and the incident involving the threat of the imposition of countervailing duties by the united states on canadian softwood lumber

the backing of government bonds and monetarism abstract this paper examines the implications of the fiscal backing of government bonds for the effects of conventional macroeconomic policies and in particular for certain monetarist propositions it shows that the validity of some basic monetarist hypotheses requires a considerable degree of accommodation by the fiscal authority relative to the central bank otherwise government bonds may matter in a manner as described in the traditional literature e g mundell 1971 patinkin 1965 though some differences arise of perhaps independent interest the framework developed in the analysis is an intertemporal general equilibrium model with all the descriptive features of the conventional flexible price is lm model

has the development gap between the ethnic minority and majority groups narrowed in vietnam evidence from household surveys using household data for rural northern vietnam between 1993 and 2014 we find that the ethnic minority group continued to lag behind the majority group in various development indicators despite the overall improvement in living standards our regression and decomposition analyses show that the structural differences between the two groups are an important cause of persistent development gap however the nature of structural differences changed over time and no single source of structural difference explains the persistent gap we argue that more minority appropriate policies are needed to lift poor minority households out of poverty further and reduce the development gap

equality of opportunity policy and measurement paradigms abstract equality of opportunity is a widely accepted principle of distributive justice and it is the leading idea of most political platforms in several countries according to this principle a society might institute policies that secure an equal distribution of the means to reach a valuable outcome among its members once the set of opportunities have been equalized which particular opportunity the individual chooses from those open to her is outside the scope of justice ex ante inequalities and only those inequalities should be eliminated or compensated for by public intervention the recent literature on the opportunity egalitarianism often merges these questions introducing two different economic issues on one side the design of a public policy intended to implement the equality of opportunity view and on the other side the problem of measuring the degree of opportunity inequality in a society we describe the basic setting and assumptions of some different approaches derived by roemer s algorithm for public policy and then we discuss some theoretical and empirical studies to separate and test alternative paradigms on the measurement of inequality of opportunity accordingly an extended critique on the causality issue on policies and measurements is taken into account

equality of opportunity and luck definitions and testable conditions with an application to income in france abstract we offer a model of equality of opportunity that encompasses different conceptions expressed in the public and philosophical debates in addition to circumstances whose effect on outcome should be compensated and effort which represents a legitimate source of inequality we introduce a third factor luck that captures the random factors whose impact on outcome should be even handed for equality of opportunity to be satisfied then we analyze how the various definitions of equality of opportunity can be empirically identified given data limitations and provide testable conditions definitions and conditions resort to standard stochastic dominance tools lastly we develop an empirical analysis of equality of opportunity for income acquisition in france over the period 1979 2000 which reveals that the degree of inequality of opportunity tends to decrease and that the degree of risk of income distributions conditional on social origin appears very similar across all groups of social origins

robust cross country analysis of inequality of opportunity abstract international rankings of countries based on inequality of opportunity indices may not be robust vis a vis the specific metric adopted to measure opportunities indices often aggregate relevant information and neglect to control for normatively irrelevant distributional factors this paper shows that gap curves can be estimated from cross sectional data and adopted to test hypotheses about robust cross country comparisons of in equality of opportunity

is it fair to make work pay the design of the income transfer program for the lower incomes is a hot issue in current public policy debate should we stick to a generous welfare state with a sizeable basic income but high marginal tax rates for the lower incomes and thus little incentives to work or should we make work pay by subsidizing the work of low earners but possibly at the cost of a smaller safety net we think it is difficult to answer this question without making clear what individuals are held responsible for and what not first we present a new fair allocation coined a pareto efficient and shared resources equivalent pese allocation which compensates for different productive skills but not for different tastes for working we also characterize a fair social ordering which rationalizes the pese allocation second we illustrate the optimal second best allocation in a discrete stiglitz 1982 1987 economy the question whether we should have subsidies for the low earners or not crucially depends on whether the low skilled have a strictly positive or zero skill third we simulate fair taxes for a sample of belgian singles our simulation results suggest that making work pay policies can be optimal according to our fairness criterion but only in the unreasonable case in which none of the unemployed are ever willing to work

ex ante versus ex post equality of opportunity we study the difference between the ex post and ex ante perspectives in equality of opportunity we show that the well documented conflicts between compensation and reward are but an aspect of a broader conflict between ex ante and ex post perspectives the literature that takes the goal of providing equal opportunities as the guiding principle generally considers that this is implemented only when ex post all individuals with the same effort obtain equal success it is easy to believe that ex ante compensation is another natural embodiment of the same idea we show that this is not true
