evaluating the economic impact of international remittances on developing countries using household surveys a literature review abstract this literature review covers 50 recent empirical studies of the economic impact of international remittances on the developing world that are based on household survey data it begins by reviewing the considerable methodological problems confronting economic work on international remittances and then examines the strengths and weaknesses of various economic studies of the impact of remittances in the developing world on such outcomes as poverty and inequality health and education investment and savings labour supply and participation and economic growth it finds that while international remittances generally have a positive impact on poverty and health in the developing world remittances can have negative effects on labour supply education and economic growth

remittances bonds and bridges remittances and social capital in burundi abstractthis study explores the effects of remittances on households structural social capital in urban burundi distinctions are made between bonding and bridging social capital referring to intra versus inter network ties of family members and friends the results demonstrate that remittance receiving households invest more in bridging social capital by participating in organisations donating time but make fewer monetary contributions compared to non receiving households remittances have mixed effects on bonding social capital receiving households give significantly less gifts to family members and friends but are more likely to send internal remittances compared to non receivers the implications of these findings for post conflict development are discussed

remittances and household wealth after conflict a case study on urban burundi few studies have researched the use of remittances in conflict affected contexts this study analyzes unique data from burundi testing three hypotheses relative deprivation investment and insurance derived from new economics of labor migration studies employing propensity score matching results show that remittances are common among wealthier households rejecting the relative deprivation hypothesis remittances have strong effects on non productive assets such as living conditions and food security and weak effects on productive assets such as asset ownership poorer households invest mostly in non productive assets suggesting that remittances are insurance for the poor whereas wealthier households seem largely unaffected by remittances

an exclusive country club the effects of the gatt on trade 1950 94 using data on bilateral trade flows from both before and after world war ii this article examines the impact of the general agreement on tariffs and trade on trade between its members and on the system of interwar trade blocs it shows that the distribution of the benefits produced by the gatt was much more highly skewed than conventional wisdom assumes the article also shows that the gold commonwealth reichsmark and exchange control blocs exerted positive and significant effects on trade after 1945 the authors attribute these effects to the bargaining protocol that governed successive rounds of gatt negotiations the signature element of the postwar trade regime

sovereign debt and its restructuring framework in the eurozone debt is a particularly serious macroeconomic problem in the eurozone public debt ratios are high by international historical standards with no immediate prospect of a significant reduction private corporate and household debt ratios are either flat or rising banks remain fragile and impose a contingent liability on the public purse the most stressed economies have not had the option of renewing economic growth through exchange rate depreciation and a boost to exports thus fiscal austerity has been their principal instrument to achieve debt reduction but since austerity also hurts growth the debt to gdp ratios have barely budged persistent low growth has also created deflationary tendencies which further raise the challenge of debt reduction

bilateral treaties and the most favored nation clause the myth of trade liberalization in the nineteenth century textbook accounts of the anglo french trade agreement of 1860 argue that it heralded the beginning of a liberal trading order this alleged success holds much interest from a modern policy point of view for it rested on bilateral negotiations and most favored nation clauses with the help of new data on international trade the ricardo database the authors provide empirical evidence and find that the treaty and subsequent network of mfn trade agreements coincided with the end of a period of unilateral liberalization across the world they also find that it did not contribute to expanding trade at all this is contrary to a deeply rooted belief among economists economic historians and political scientists the authors draw a number of policy lessons that run counter to the conventional wisdom and raise skepticism toward the ability of bilateralism and mfn arrangements to promote trade liberalization

lessons from the past capital markets during the 19th century and the interwar period on friday 13 august 1982 finance minster jesus silva herzog of mexico made a series of visits to the international monetary fund the federal reserve and the u s treasury his message to each was the same mexico could no longer continue to service its debt thus began a dramatic weekend of negotiations that marked the end of the preceding decade s buoyant expansion of developing country debt and the start of a still continuing response to the sudden collapse

the forgotten history of domestic debt there is a rich scholarly literature on sovereign default on external debt comparatively little is known about sovereign default on domestic debt even today cross country data on domestic public debt remains curiously exotic particularly prior to the 1980s we have filled this gap in the literature by compiling a database on central government public debt external and domestic the data span 1914 to 2010 for most countries reaching back into the nineteenth century and earlier for many our findings here on debt sustainability sovereign defaults the temptation to inflate and the hierarchy of creditors only scratch the surface of what the domestic public debt data can reveal first domestic debt is big for the 64 countries for which we have long time series domestic debt accounts for almost two thirds of total public debt for most of the sample this debt carries a market determined interest rate except for the financial repression era between wwii and financial liberalization second the data go a long way toward explaining the puzzle of why countries so often default on their external debts at seemingly low debt thresholds third domestic debt has largely been ignored in the vast empirical work on inflation in fact domestic debt a significant portion of which is long term and nonindexed is often much larger than the monetary base in the run up to high inflation episodes last the widely held view that domestic residents are strictly junior to external creditors does not find broad support

optimal timing of decisions a general theory based on continuation values abstract by extending a methodology dating back to jovanovic 1982 we develop a comprehensive theory of optimal timing of decisions based on continuation value functions and operators that act on them rewards can be bounded or unbounded one advantage of this approach over standard bellman methods is that continuation value functions are smoother than value functions another is that for a range of problems the continuation value function exists in a lower dimensional space than the value function we exploit these advantages to obtain a range of new results on optimality optimal behavior and efficient computation

modeling the search for the least costly opportunity abstract with the continuing growth in the number of opportunities available at virtual stores over the internet there is also a growing demand for the services of computer programs capable of scanning a large number of stores in a very short time we assume that the cost associated with each scan is linear in the number of stores scanned and that the resulting list of price quotes is not always satisfactory to the customer in which case an additional scan is performed and so on in such a reality the customer wishing to minimize her expected cost must specify the requested sample size and a rule control limit to stop the search in the context of search theory the above search model can be categorized as fixed sample size sequential with infinite horizon according to this model the expected search cost is a function of two decision variables the sample size and the control limit we prove that for arbitrary sample size the expected search cost is either quasi convex or strictly decreasing in the control limit and that the optimal expected search cost is quasi convex in the sample size these properties allow an efficient calculation of the optimal policy we also develop analytic formulas to calculate the cost s variance allowing customers to choose a slightly higher expected cost if there is a considerable decrease in the variance finally we present detailed examples for price quotes that are distributed uniformly or exponentially

the democratic advantage institutional foundations of financial power in international competition despite their presumed liabilities institutions associated with democracy serve as a source of power in prolonged international competition by increasing the financial resources that states can bring to bear the theory of sovereign debt suggests that a state s ability to raise money through public borrowing is enhanced when debtholders have mechanisms for sanctioning state leaders in the event of default institutions associated with liberal government provide such mechanisms all other things being equal states that possess these institutions enjoy superior access to credit and lower interest rates than do states in which the sovereign has more discretion to default unilaterally liberal states can not only raise more money from a given economic base but can also pursue tax smoothing policies that minimize economic distortions the ability to finance competition in a manner that is consistent with long term economic growth generates a significant advantage in prolonged rivalries these claims are explored by analyzing the anglo french rivalry 1688 1815 and the cold war

sovereign debt defaults insights from history history provides many insights to address the issue of sovereign debt defaults this article first presents a detailed account of defaults in historical perspective it then discusses the solutions devised in the past to address sovereign debt crises and puts these into perspective with today s answers when crises occur finally the paper stresses the role of history when the events studied do not occur frequently and when archival data may shed new light on the process of the resolution of crises the impact of odious debts declarations of state succession and of international relations on sovereign defaults and on their settlement is thus also addressed copyright 2013 oxford university press

the peaceful conspiracy bond markets and international relations during the pax britannica this article provides foundations to polanyi s famed argument that monopoly power in the global capital market served as an instrument of peace during the pax britannica 1815 1914 our perspective is novel we focus on the role of intermediaries and certification we show that when information and enforcement are imperfect there is scope for the endogenous emergence of prestigious intermediaries who enjoy a monopoly position and as a result control government actions they can implement conditional lending they subject the distribution of credit to the adoption of peaceful policies prestigious intermediaries act that way because of their concern with maintaining an unblemished track record when wars increased risks of default our analysis which brings together insights from different disciplines provides a significant extension to and departure from recent research on how countries accumulate reputational capital

war international finance and fiscal capacity in the long run in this article i revisit the relationship between war and state making in modern times by focusing on two prominent types of war finance taxes and foreign loans financing war with tax money enhances the capacity to assess wealth and monitor compliance namely fiscal capacity tax financed war facilitates the adoption of power sharing institutions which transform taxation into a non zero sum game carrying on the effect of war in the long run financing war with external capital does not contribute to long term fiscal capacity if borrowers interrupt debt service and as part of the default settlement war debt is condoned or exchanged for nontax revenue the empirical evidence draws from war around the world as early as 1816 results suggest that globalization of capital markets in the nineteenth century undermined the association between war state making and political reform

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

the inequality of social capital and the reproduction of chronic poverty summary this paper draws on ethnographic research in tanzania to question ideas inherent to mainstream development policy that building social capital can be readily created used or substituted for other missing assets and thereby overcome poverty the poorest experience clusters of interlocking disadvantage that make it highly unlikely that they can draw on social capital to ameliorate their poverty or that increased association and participation at community level is necessarily beneficial to them moreover social relationships collective action and local institutions may structurally reproduce the exclusion of the poorest as such a politically neutral and undersocialized policy focus on strengthening associational life and public participation of the poor is unlikely to lead to their greater inclusion nor to significant poverty alleviation

debt and default in the 1930s causes and consequences abstract this paper studies interwar experience with external debt and default it begins with a description of the contours of international borrowing and lending in the 1920s we then use some empirical models from recent literature on the 1970s to describe the interwar data macroeconomic variables for over 20 countries are related to cross section variations in borrowing and debt during the period from the end of the 1920s to 1938 the paper then considers the incidence and correlates of sovereign default for 1934 1938 using regression to determine the association between standard measures of economic structure and performance and subsequent interruptions to debt service such variables as the magnitude of the debt burden the deterioration of the terms of trade during the great depression and the stance of monetary and fiscal policies provide a remarkably accurate explanation of the incidence of default we go on to provide a long run perspective on default and on the remedies available to creditors the provisions of loan contracts are reviewed with an eye toward analyzing the scope for renegotiation the discussion emphasizes the contrast between the regime of bond finance that prevalied in the interwar years and the current regime of bank lending we analyze the roles of governments banks and bondholders protective committees in the negotiation process we then present new estimates of the ex post realized rates of return on british and american foreign lending in the 1920s this empirical analysis uncovers a striking contrast in the returns realized on loans floated in the two countries while the nominal internal rate of return on dollar loans was less than 1 per annum the comparable return on sterling loans was in excess of 5 the paper concludes with a discussion of factors which help to account for this dramatic difference

who should be interviewed in surveys of household income summary this study tests the null hypothesis that it is sufficient to interview only the household head to obtain accurate information on household income results show that using a husband s estimate of his wife s income does not produce statistically reliable results for poverty analysis estimates of the wife s income provided by the husband and wife are in agreement in only 6 of households while limiting interviews to one person has the advantage of reducing the time and expense of household surveys this appears detrimental in terms of accuracy and may lead to incorrect conclusions on the determinants of poverty

inequality lobbying and resource allocation this paper describes how wealth inequality may distort public resource allocation a government seeks to allocate limited resources to productive sectors but sectoral productivity is privately known by agents with vested interests in those sectors they lobby the government for preferential treatment the government even if it honestly seeks to maximize economic efficiency may be confounded by the possibility that both high wealth and true economic desirability create loud lobbies broadly speaking both poorer economies and unequal economies display greater public misallocation the paper warns against the conventional wisdom that this is so because such governments are more corrupt jel d72 d78 d82 016 in this paper we propose a particular channel through which wealth inequality distorts the resource allocation process our analysis rests on four premises

development and social capital abstract this paper examines social capital and its relation with economic development we focus on the role that interpersonal relationships play in social exchange whether through the market or through the provision of public goods by facilitating search and trust social capital can increase the efficiency of social exchange where formal institutions are weak but the benefits from social capital are likely to be unequally distributed given these features documenting empirically the benefits of social capital is complicated by the presence of negative and positive externalities and by the existence of leadership and group effects lessons for development policy are drawn at the end

implementation cycles investment and growth we develop a model of intrinsic cycles driven by the decentralized behavior of entrepreneurs and firms making continuous divisible improvements in their productivity we show that when the introduction of productivity improvements is endogenous implementation cycles arise even in the presence of reversible investment and consumption smoothing the implied cyclical equilibrium is unique within its class and shares several features in common with actual business cycles in particular its predictions are qualitatively consistent with the joint behavior of the investment rate and tobin s q during u s recessions

the output costs of hard and soft sovereign default abstract how costly are sovereign debt crises in this paper we study output losses during sovereign default and debt renegotiation episodes since 1980 in contrast to previous work we account for the severity of default and not only for its occurrence specifically we distinguish between hard and soft defaults using new data on debtor payment and negotiation behavior and on the size of haircuts towards private external creditors we show that hard defaults are associated with a much steeper drop in gdp of up to ten percent compared to soft defaults the results are consistent with theoretical models assuming proportional output costs of default

welfare effects of british free trade debate and evidence from the 1840s the classical economists engaged in a vigorous debate over whether britain s tariff reductions in the 1840s should be made contingent on tariff liberalization abroad some notably robert torrens believed that a unilateral tariff reduction would so deteriorate british terms of trade as to outweigh efficiency gains and make the country worse off in this paper britain s foreign trade elasticities are estimated for this period in a simultaneous equation model they are used in a simple general equilibrium model that explicitly takes the terms of trade into account to assess the welfare impact of tariff reductions the results indicate that britain would have been made worse off from a unilateral tariff reduction however foreign tariff reductions mitigated the terms of trade deterioration and could easily have made britain better off

historical research on international lending and debt the parallels between debt crises past and present have attracted a large number of social scientists to the history of foreign lending and default in this article i describe the findings of the recent literature on the subject the questions posed have obvious relevance to the current policy debate over the debt of less developed countries what features of international capital markets have long rendered them vulnerable to generalized crisis what events tend to spawn debt servicing difficulties and to provoke default what have been the consequences of default for lenders and borrowers what approaches historically have proven most effective at clearing away the residue of debt crises i concentrate on 20th century experience on the lending of the 1920s on the debt crisis of the 1930s and on the recovery of capital markets after world war ii

the new economics of labor migration this paper reviews selected theoretical and empirical developments in the field of labor migration economics the migration behavior of individuals differs in accordance with their perceived relative deprivation those who are relatively more deprived tend to have stronger incentive to migrate than those who are relatively less deprived moreover a reference group characterized by more income inequality is likely to generate more relative deprivation highly skilled workers are also more likely to migrate migration decisions are often made jointly by the migrant and nonmigrant with a contractual arrangement regarding the sharing of costs and returns the exchange of commitments to share income provides coinsurance of particular interest are the determinants of the speed of adoption of migration as an innovation and the characteristics associated with the delay in the adoption of innovation new econometric techniques including techniques for the analysis of qualitative dependent variables techniques that correct for sample selection bias and those for the analysis of longitudinal data have substantially benefited empirical research in this area new methods that can correct for the biased estimate of the wages particular individuals would receive at 2 or more locations at the same point in time allow researchers to test locational decsion making models estimates of these structural models of labor migration support the hypothesis that individuals respond to income incentives in making the decsion to migrate further research is needed on the pazzling observation that migrant workers earn less than native born workers with similar characteristics during the 1st few years after migration but more thereafter other topics that need further research include the macroeconomic effects of migration the microeconomic and macroeconomic relationships between aging and labor migration and the migration behavior of dual earner families

feeling the blues moral hazard and debt dilution in eurobonds before 1914 debt mutualisation through eurobonds has been proposed as a solution to the euro crisis although this proposal found some support it also attracted strong criticisms as it risks raising the spreads for strong countries diluting legacy debt and promoting moral hazard by weak countries because eurobonds are a new addition to the policy toolkit there are many untested hypotheses in the literature about the counterfactual behaviour of markets and sovereigns this paper offers some tests of the issues by drawing from the closest historical parallel five guaranteed bonds issued in europe between 1833 and 1913 the empirical evidence suggests that contemporary concerns about fiscal transfers and debt dilution may be overblown and creditors moral hazard may be as much of a problem as debtors

r d expenditure in g7 countries and the implications for endogenous fluctuations and growth abstract the literature on endogenous growth cycles predicts countercyclical r d expenditure aggregate r d expenditure in g7 countries from 1973 to 2000 tends to be procyclical implications for future theoretical research are discussed

sovereign states bondholders committees and the london stock exchange in the nineteenth century 1827 68 new facts and old fictions this paper unpacks the role of foreign bondholders committees in influencing market access following a default during the era before the creation of the british corporation of foreign bondholders cfb in 1868 i argue that many ideas about this period need to be revisited in particular my evidence which uses archival work to describe market microstructures shows the importance of the london stock exchange lse as a court of arbitration i show how the lse general purpose committee set up a system of collective action clauses requiring majority agreement among bondholders to permit market access i argue that unlike what research has argued thus far this created powerful incentives for bondholders to get organized as they did previous models and historical lessons need to be recast copyright 2013 oxford university press

sovereign debt the assessment this article serves as an introduction to two issues of the oxford review of economic policy one entitled sovereign debt understanding bond markets during the eurozone crisis and the second sovereign debt lessons from the past reforms for the future we begin by documenting recent trends in advanced country sovereign indebtedness and reviewing events that preceded the sovereign debt crisis in the eurozone the mechanisms through which rising sovereign debt may impact bond yields economic growth and inflation are discussed and the evidence for such effects is reviewed our discussion highlights that there is no unique threshold beyond which sovereign debt exerts adverse macroeconomic effects and that in order to understand the consequences of a given debt load one must analyse its structure in terms of internal and external creditors currency denomination the time to maturity of the bonds and the legal code governing debt issuance as well as various economic and political constraints measuring the fiscal space of the sovereign we then turn our attention to episodes in which sovereign debt proves excessive and default occurs we review explanations for the protracted and inefficient nature of defaults and describe some lessons from historical studies examining default outcomes in the final part of the paper we discuss proposals for averting future debt crises including jointly issued bonds such as eurobonds contingent convertible bonds and elements of a sovereign debt restructuring mechanism in the course of our discussion we draw on each of the 11 articles included in the two issues of this journal devoted to sovereign debt copyright 2013 oxford university press

the effects of systemic banking crises in the inter war period abstract this paper examines the time profile of the impact of systemic banking crises on gdp and industrial production using a panel of 24 countries over the inter war period and compares this to the post war experience of these countries we show that banking crises have effects that induce medium term adjustments on economies focussing on an eight year horizon it is clear that the negative effects of systemic banking crises last over the entirety of this time horizon the effect has been identified for gdp and industrial production the adverse effect on the industrial sector stands out as being substantially larger in magnitude relative to the macroeconomic effect comparing the results across long run historical periods for the same selection of countries and variables identifies some differences that stand out the short term macroeconomic impact effects are much larger in the post war period suggesting that the propagation channels of shocks operate at a faster pace in the more recent period moreover the time profile of effects differs suggesting that modern policies may be modulating the temporal shape of the response to banking crises shocks however the broad magnitude of the adverse effect of banking crises remains comparable across these time periods

the case for trade liberalization in developing countries in a broad swing of the pendulum developing countries have been shifting from severe and destructive protection to free trade fever many of the notable examples are in latin america mexico after a major unilateral trade liberalization is now negotiating a free trade agreement with canada and the united states chile traditionally a highly protected country is a leading example of reducing trade barriers argentina and brazil have entered free trade agreements a free trade area for the americas is becoming a serious possibility the enthusiasm for more openness of the economy is not limited to latin america for example korea and turkey are cases of highly successful liberalization there are also cases in africa for example ghana and botswana to demonstrate the possibility and the benefits of opening up this new enthusiasm for freer trade stems from four overlapping sources anti statism the world has seen a broad intellectual swing away from emphasizing the beneficial role of the state in the 1980s and protection is seen as one of the manifestations of an overly intrusive state of course a shift to a liberal trade regime has not always been the by product of a more democratic society chile under pinochet or korea in its liberalizing phase were under authoritarian rule two cheers for the market but not three the saying goes today the market gets at least three cheers which may be at least one too many poor economic performance many developing countries have suffered dismal economic performance and declining productive potential much of the reason can be traced to populist macroeconomic policies that engendered debt crises and hyperinflation of course part of the reason was also a very adverse external environment but since the days of plentiful external credit are gone

enhanced debt management solving the eurozone crisis by linking debt management with fiscal and monetary policy abstract unconventional approaches to suit unusual circumstances have become acceptable in monetary policy a formerly highly conservative discipline in this paper it is argued that unconventional approaches should also be considered in sovereign debt management in order to contribute to resolving the eurozone sovereign debt crisis first the troika crisis lending to indebted sovereign borrowers in the eurozone is reviewed and compared with standard imf post crisis lending the main difference and shortcoming is the unsustainable character of the eurozone approach due to the omission of demand stimulation components to address this and other shortcomings the features of an ideal alternative funding tool are identified it would solve the funding problems of affected sovereigns help stabilise the banking system but most of all stimulate domestic demand and hence end the vicious downward spiral it is found that this funding method can be implemented as part of enhanced public debt management by each nation s debt management office

state market civil institutions the case of eastern europe and the soviet republics abstract the transition tasks facing the countries of central and eastern europe are monumental the public sector will play a dominant role during the transition process available evidence suggests that orthodox prescriptions for public sector reform cannot be effectively implemented without an underlying constitution and a legal and regulatory infrastructure lri a well designed constitution and lri instill confidence and policy credibility with perfectly rational expectations and confidence in the constitution and lri the sequence of reforms matters little future reforms are perfectly anticipated today and agents act as though the reforms will occur with certainty short of such confidence reforms need to be simultaneously pursued on many fronts the most important activity is to redefine the role of the state setting a constitution that clearly defines and secures basic political civil and economic freedoms and designing an lri that creates a fertile environment for a vibrant market economy

endogenous growth cycles current explanations why a growing economy necessarily goes through periods of high and low growth predict countercyclical r d investment as this is very controversial from an empirical perspective a stochastic poisson model of endogenous growth cycles is presented where the determinants of the cyclical behaviour of r d investment are analytically studied providing an explicit expression for the expected length of a cycle shows that high frequency fluctuations can indeed be understood by this approach it is also shown how small technological improvements translate into large aggregate fluctuations

volatility and slow technology diffusion abstract i study the effects of uncertainty on technology adoption and thereby on volatility and growth i present an analytically tractable model in which i uncertainty about the returns to adoption delays technology diffusion and ii the mean and volatility of output growth are jointly determined in equilibrium i then test the key predictions of the model by studying the introduction of three major information and communication technologies icts computers internet and cell phones i find that countries with more volatile growth rates of real gdp per capita have higher time adoption lags and lower average growth as predicted by the model

sovereign debt as intertemporal barter author s kletzer kenneth m wright brian d abstract borrowing and lending between sovereign parties is modeled as intertemporal barter that smoothes the consumption of a risk averse party subject to endowment shocks the surplus anticipated in the relationship offers sufficient incentive for cooperation by all parties including any other competitive agents who are potential lenders to the sovereign the sole punishments consist of renegotiation proof changes in the path of future payments we show that intertemporal trade can be sustained in the absence of any exogenous enforcement of lending relationships whatsoever that is borrowing and lending are possible under anarchy and are supported by punishments that consist of cheating any cheater long term implicit relationships may be fulfilled as the continual renegotiation of simple incomplete short term loans the analysis suggests that the crucial role of the explicit loan contract is the identification of the relationship and the parties involved

the economic determinants of technology shocks in a real business cycle model abstract creative destruction due to new technologies causes both long run growth and short run business fluctuations new technologies push the economy on a higher productivity level but also imply partial obsolescence of old production units obsolescence induces an adjustment period during which growth rates gradually fall at some endogenously determined point research for the next technology starts once the new technology is discovered a technology shock occurs and the next cycle starts this is shown in a continuous time rbc model with risk averse agents where savings can be used for financing deterministic capital accumulation and stochastic r d for new technologies

explaining output volatility the case of taxation this paper presents strong empirical evidence that the observed heterogeneity of output volatility across countries and over time is partly endogenous in particular based on a closed form solution we obtain a long run equilibrium relationship between taxes and output volatility in the stochastic neoclassical growth model by showing that asymptotically the variance of output growth rates is affected by the level of taxes without affecting the mean we estimate the tax semi elasticities on output volatility and provide convincing empirical evidence that taxes are important to understand differences in output volatility among oecd countries

remittances household expenditure and investment in guatemala the author uses a large household data set from guatemala to analyze how the receipt of internal remittances from guatemala and international remittances from the united states affects the marginal spending behavior of households on various consumption and investment goods contrary to other studies the author finds that households receiving remittances actually spend less at the margin on consumption food and consumer goods and durables than do households receiving no remittances instead of spending on consumption households receiving remittances tend to spend more on investment goods like education health and housing the analysis shows that a large amount of remittance money goes into education at the margin households receiving internal and international remittances spend 45 and 58 percent more respectively on education than do households with no remittances these increased expenditures on education represent investment in human capital like other studies the author finds that remittance receiving households spend more at the margin on housing these increased expenditures on housing represent a type of investment for the migrant as well as a means for boosting local economic development by creating new income and employment opportunities for skilled and unskilled workers

the accumulation of wealth and the cyclical generation of new technologies a search theoretic approach in this paper sustained technological progress results from the feedback between technical change and the accumulation of wealth the production technology is affected by a productivity factor which ensues from research and development the research and development process is described as a sequential search problem in which optimal decisions depend on current levels of wealth and technology the resulting growth path displays invention cycles a discovery of a significant technological improvement at the end of a search phase is followed by periods of growth without search eventually sufficient wealth is accumulated research and development resumes and a new cycle begins copyright 1996 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association
