unequal vulnerability to climate change and the transmission of adverse effects through international trade in this paper we consider the unequal distribution of climate change damages in the world and we examine how the underlying costs can spread from a vulnerable to a non vulnerable country through international trade to focus on such indirect effects we treat this topic in a north south trade overlapping generations model in which the south is vulnerable to the damages entailed by global pollution while the north is not we show that the impact of climate change in the south can be a source of welfare loss for northern consumers in both the short and the long run in the long run an increase in the south s vulnerability can reduce the welfare in the north economy even in the case in which it improves its terms of trade in the short run the south s vulnerability can also represent a source of intergenerational inequity in the north therefore we emphasize the strong economic incentives for non vulnerable and a fortiori less vulnerable economies to reduce the climate change damages on more vulnerable countries

inefficient credit booms this paper studies the welfare properties of competitive equilibria in an economy with financial frictions hit by aggregate shocks in particular it shows that competitive financial contracts can result in excessive borrowing ex ante and excessive volatility ex post even though from a first best perspective the equilibrium always displays under borrowing from a second best point of view excessive borrowing can arise the inefficiency is due to the combination of limited commitment in financial contracts and the fact that asset prices are determined in a spot market this generates a pecuniary externality that is not internalized in private contracts the model provides a framework to evaluate preventive policies which can be used during a credit boom to reduce the expected costs of a financial crisis copyright 2008 wiley blackwell

more mortgages lower growth in newly collected data on 46 economies over 1990 2011 we show that financial development since 1990 was mostly due to growth in credit to real estate and other asset markets which has a negative growth coefficient we also distinguish between growth effects of stocks and flows of credit we find positive growth effects for credit flows to nonfinancial business but not for mortgage and other asset market credit flows by accounting for the composition of credit stocks and for the effect of credit flows we explain the insignificant or negative growth effects of financial development in recent times what was true in the 1960s 1970s and 1980s when the field of empirical credit growth studies blossomed is no longer true in the 1990s and 2000s new bank lending is not primarily to nonfinancial business and financial development may no longer be good for growth these trends predate the 2008 crisis they prompt a rethink of the role of banks in the process of economic growth jel e44 o16 o40 c33

finance and the sources of growth at various stages of economic development this article studies the effects of financial development on the sources of growth in different groups of countries recent theoretical work shows that financial development may affect productivity and capital accumulation in different ways in industrial versus developing countries this hypothesis is tested with panel data from 74 countries using gmm dynamic panel techniques results are consistent with the hypothesis finance has a strong positive influence on productivity growth primarily in more developed economies in less developed economies the effect of finance on output growth occurs primarily through capital accumulation jel o4 g1

bank risk taking securitization supervision and low interest rates evidence from the euro area and the u s lending standards using a unique dataset of the euro area and the u s bank lending standards we find that low monetary policy short term interest rates soften standards for household and corporate loans this softening especially for mortgages is amplified by securitization activity weak supervision for bank capital and low monetary policy rates for an extended period conversely low long term interest rates do not soften lending standards finally countries with softer lending standards before the crisis related to negative taylor rule residuals experienced a worse economic performance afterward these results help shed light on the origins of the crisis and have important policy implications the author 2011 published by oxford university press on behalf of the society for financial studies all rights reserved for permissions please e mail journals permissions oup com oxford university press

good for living on the relationship between globalization and life expectancy this paper analyzes the relationship between three dimensions economic social and political of globalization and life expectancy using a panel of 92 countries covering the 1970 2005 period using different estimation techniques and sample groupings we find that economic globalization has a robust positive effect on life expectancy even when controlling for income nutritional intake literacy number of physicians and several other factors the result also holds when the sample is restricted to low income countries only in contrast political and social globalization have no such robust effects

temperature shocks and establishment sales combining granular daily data on temperatures across the continental united states with detailed establishment data from 1990 to 2015 we study the causal impact of temperature shocks on establishment sales and productivity using a large sample yielding precise estimates we do not find evidence that temperature exposures significantly affect establishment level sales or productivity including among industries traditionally classified as heat sensitive at the firm level we find that temperature exposures aggregated across firm establishments are generally unrelated to sales productivity and profitability our results support existing findings of a tenuous relation between temperature and aggregate economic growth in rich countries

climate shocks and international trade evidence from china abstract this paper examines the impacts of climate shocks on international trade in china we find that there are substantial climate effects on exports but only little impacts on imports poorer warmer and non coastal cities suffer more from a warming climate

low carbon development for the least developed countries the global community has to act collectively to halt climate change but such collective action must take into account the development needs of the least developed countries ldcs which are likely to be hit earliest and hardest by climate change the priority of such countries remains poverty alleviation and the achievement of the millennium development goals but the three challenges of limiting climate change adapting to its consequences and reducing poverty have to be faced together this requires ldcs eventually to follow a development path that differs from those trodden by today s industrial countries and emerging market economies there is no room in the long term for high emission economies and high carbon growth is unsustainable given the possible consequences for fossil fuel supplies and climate change impacts

estimating the efficiency of the system of healthcare financing in achieving better health this paper contributes to the effort to model and measure how the method of financing of health expenditure affects the efficiency with which better health can be achieved the focus is on the health system efficiency at the country level which provides an alternative to the work done in the who in this regard the approach uses frontier techniques as in the who studies however the paper appeals to the economic index number theory of quantity and productivity indexes which have well established axiomatic properties and provides a means for aggregating multiple health output proxies without having to attach arbitrary weights this allows the proposal of a specification that embeds health sector performance in a broader index of economic inputs and outputs and allows for comparisons across countries and time

weather variations and international trade in this paper i investigate the effect of weather variations in the exporter and importer countries separately as well as a the difference between weather variations in both countries on bilateral trade flows the analysis is done at the country sectoral and product levels worldwide and over the 1992 2014 period i find a negative effect of temperature variations in the exporter country and in the difference between exporter and importer countries on bilateral trade at the country level at the product level both negative and positive effects arise but the negative effect of temperature dominates the temperature effects are on the agricultural and manufacturing sectors especially in the textile and metals sectors i show that possible channels are the impact of temperature on output and labour productivity the negative impacts are larger in exporter countries that are closer to the equator that have lower quality of institutions and that export to more remote countries if countries are able to adapt to climate change the long term effects of temperature variations should be lower than the contemporaneous effect nevertheless my results on the long term effects analysis do not support this hypothesis suggesting no or very low adaptation moreover the negative effect of temperature is persistent and cumulative through several years after the temperature shock concerning precipitation variation effects they are found mainly at the product level with the positive effect dominating for the affected products

when credit bites back using data on 14 advanced countries between 1870 and 2008 we document two key facts of the modern business cycle relative to typical recessions financial crisis recessions are costlier and more credit intensive expansions tend to be followed by deeper recessions in financial crises or otherwise and slower recoveries we use local projection methods to condition on a broad set of macro economic controls to study how past credit accumulation impacts key macro economic variables such as output investment lending interest rates and inflation the facts that we uncover lend support to the idea that financial factors play an important role in the modern business cycle

same financial development yet different economic growth why we re study the relationship between financial development and real gdp per capita growth in 48 countries what we find is an interesting evidence that only stock market development has positive effects on growth and that banking development has an unfavorable if not negative effect on growth we examine whether or not these impacts are a product of various financial and economic conditional variables our conditional variables consist of financial liberalization two sets of country development dummies crises in banking and currency dummies the creditor protection index as well as the anti director and corruption indices our results clearly show that the conditional variables of financial liberalization high income level and good shareholder protection mitigate the negative impacts of banking development on growth in contrast the conditional variables of middle income level regional latin american sub saharan african and east asian dummies banking and currency crises good creditor protection and higher corruption strengthen the negative impacts of banking development on growth next the conditional variables of middle income level latin american sub saharan african and east asian dummies strengthen the positive impacts of stock market development on growth whereas the conditional variables of financial liberalization mitigate the positive impacts of stock market development on growth last we find that the relationship between growth and bank development is better described as a weak inverse ushape this inverse u shape becomes stronger when additional stock market variables are squared thus financial development and growth may in fact be in a nonlinear form

health behavior health knowledge and schooling the positive correlation between schooling and good health is well documented one explanation is that schooling helps people choose healthier life styles by improving their knowledge of the relationship between health behaviors and health outcomes that is schooling improves the household s allocative efficiency in producing health this empirical study uses direct measures of health knowledge to test this explanation part of the relationship between schooling and the consumption of cigarettes alcohol and exercise is explained by differences in health knowledge however most of schooling s effects on health behavior remain after differences in knowledge are controlled for

rising household debt its causes and macroeconomic implications a long period analysis the article analyses the rise in household indebtedness from the point of view of its causes and long run macroeconomic implications the analysis is focussed on the us case differently from life cycle interpretations of the phenomenon and from interpretations in terms of erratic deviations of current income flows from their long run trend the rising household debt is viewed as the outcome of persistent changes in income distribution and growing income inequalities through household debt low wages appear to have been brought to coexist with relatively high levels of aggregate demand thus providing the solution to the contradiction between the necessity of high and rising consumption levels for the growth of the system s actual output and a framework of antagonistic conditions of distribution which keeps within limits the real income of the vast majority of society the question of the long run sustainability of this substitution of loans for wages is finally discussed copyright the author 2008 published by oxford university press on behalf of the cambridge political economy society all rights reserved oxford university press

rain agriculture and tariffs this paper examines whether and how rainfall shocks affect tariff setting in the agricultural sector in a model of strategic trade policy the authors show that the impact of a negative rainfall shock on optimal import tariffs is generally ambiguous depending on the weight placed by the domestic policy maker on tariff revenue profits and the consumer surplus the more weight placed on domestic profits the more likely it is that the policy maker will respond to a rainfall shortage by reducing import tariffs these findings are robust to alternative assumptions about market structure and the timing of the game using detailed panel data on applied tariffs and rainfall for 70 nations the authors find robust evidence that rainfall shortages generally induce policy makers to set lower tariffs on agricultural imports

climate shocks and exports this paper uses international trade data to examine the effects of climate shocks on economic activity we examine panel models relating the annual growth rate of a country s exports in a particular product category to the country s weather in that year we find that a poor country being 1 degree celsius warmer in a given year reduces the growth rate of that country s exports by between 2 0 and 5 7 percentage points with no detectable effects in rich countries we find negative effects of temperature on exports of both agricultural products and light manufacturing products with little apparent effects on heavy industry or raw materials the results confirm large negative effects of temperature on poor countries economies and suggest that temperature affects a much wider range of economic activity than conventionally thought this abstract was borrowed from another version of this item

the efficiency of the health system in south africa evidence from stochastic frontier analysis the availability of increased resources and the lack of parallel improvement in health status have renewed interest on health system performance particularly where progress towards the millennium development goals has been slow since the political transition in 1994 south africa has consistently invested over eight of its gross domestic product gdp on health but so far returns remain uneven with some localities delivering lower outcomes than others even when they have comparable input levels this study measures the performance of the country s health system following a stochastic production frontier approach results have revealed that eight of the 52 districts in the country had an efficiency score of below 60 and in four of these the score was below 50 technical inefficiency was positively and significantly associated with hiv prevalence and illiteracy rates reported for districts overall mean technical efficiency te in the country was around 80 given this further improvements in he

industrial output fluctuations in developing countries general equilibrium consequences of agricultural productivity shocks abstract this paper shows that a negative shock to agricultural productivity may increase food prices and labor and capital can move away from manufacturing into agriculture to meet the subsistence requirement for food this effect depends on income levels and openness to trade using annual manufacturing data and rainfall shocks as the instrument for crop yields proxy for agricultural productivity i find that an exogenous decline in yield decreases manufacturing output as well as employment and capital investment in manufacturing overall crop yield variation can explain up to 44 of industrial output fluctuations in developing countries rainfall shocks cause 31 of the fluctuations lastly this paper shows that such perverse phenomena in which resources move toward the sector with declining productivity can lead to a significant reduction in aggregate productivity

tracking the stepwise effects of regulatory reforms over time a back door approach most of the literature on the efficiency effects of regulatory reforms ignores the gradual nature of the implementation of these reforms this article describes a new simple data manipulation that minimizes data requirements to measure econometrically the impact on efficiency of each stage of multi stages regulatory reforms the approach can easily be implemented using standard stochastic frontier software programs it is illustrated with data on the spanish port system which went through a two stage reform during the 1990s

inequalities in health some international comparisons there have been many attempts to compare various dimensions of inequality between different countries including particularly those relating to income and wealth however there have been relatively few international studies of inequalities in health 2 given that as has been noted by economists as eminent as kenneth arrow and amartya sen 3 individuals states of health are contributors to welfare comparable in impact to income or wealth holdings this relative poverty of health studies is surprising it cannot be explained by lack of data such studies of health inequality as do exist generally concern mortality and the data situation here is significantly better than that for other welfare indicators such as income there are extensive data available for a large number of countries although the quality varies see united nations 1982 it is likely to be generally higher than that for income data moreover there are fewer methodological problems associated with the data for obvious reasons mortality is easier to define than income and there is no problem equivalent to that of defining the income unit

credit constraints and gdp growth evidence from a natural experiment abstract before 1998 texas was the only state that greatly restricted home equity loans and cash out refinancing for non housing consumption such borrowing was authorized in texas for the first time through a constitutional amendment in 1998 using state level panel data and recently developed synthetic control methods based on machine learning we find that the texas constitutional amendments relaxing credit constraints had an insignificant impact on gdp growth our findings have important policy implications for the stimulative effect of easier home equity access on gdp growth

estimating a health production function for the us some new evidence this study reports some new evidence on the impact of medical care socioeconomic lifestyle and environmental factors on the health status of the population of the usa the results show that additional medical care utilization is relatively ineffective in lowering mortality and increasing life expectancy the most important factors that influence death rates are related to socioeconomic status and lifestyle the results suggest that health care policy which focuses primarily on the provision of medical care services and ignores larger economic and social considerations may do little to benefit the nation s health

the finance and growth nexus revisited we find that an expansion of credit has a positive effect on per capita output growth only up to a point beyond this threshold the impact of finance on growth is not statistically significant anymore we show however that the estimated non linear relationship may stem from the omission of factors not considered in the literature so far these factors may have a negative impact on growth in mature financial systems and include the magnitude of financial cycles as well as the importance of non intermediation activities in banks business models

financial dependence global growth opportunities and growth revisited abstract we show that financial development has a non monotonic effect on growth in the rajan and zingales 1998 and fisman and love 2007 sample beyond a threshold financially dependent industries and industries facing good growth opportunities grow disproportionately more slowly

measuring poverty in a growing world or measuring growth in a poor world the extent to which growth reduces global poverty has been disputed for 30 years although there are better data than ever before controversies are not resolved a major problem is that consumption measured from household surveys which is used to measure poverty grows less rapidly than consumption measured in national accounts in the world as a whole and in large countries particularly india china and the united states in consequence measured poverty has fallen less rapidly than appears warranted by measured growth in poor countries one plausible cause is that richer households are less likely to participate in surveys but growth in the national accounts is also upward biased and consumption in the national accounts contains large and rapidly growing items that are not consumed by the poor and not included in surveys so it is possible for consumption of the poor to grow less rapidly than national consumption without any increase in measured inequality current statistical procedures in poor

price and quantity in international comparisons of health care expenditure an important omission from earlier cross national comparisons of health care expenditure has been the failure to distinguish between price and quantity using recent data on purchasing power parities the purpose of this article is to report some preliminary results regarding health care expenditure and quantity across 22 oecd countries the article concludes that contrary to what has been suggested in some recent articles the relative price of health care is not correlated to the aggregate per capita income the fraction of the national income that is devoted to health care provision increases with the per capita income regardless of whether health care is measured in terms of expenditure or quantity the relative price of health care has a rationing effect on the quantity of health care that is offered with a price alasticity close to minus one the latter finding means that the health care expenditure is not greater in countries with higherprices furthermore the differences in health care expendit

decomposition of total factor productivity in world health production a stochastic frontier approach while countries around the globe have increased spending on health care economists and policy makers have raised concerns over the productivity and efficiency of health care this article applies a stochastic frontier approach to address this issue using data from 141 countries for the period 1993 to 1997 from the perspective of productivity change our results suggest that gains in population health will be greater provided that more resources are allocated to investment in human capital we also show that the scale component accounts for 65 70 of the productivity change that is omitting the scale component in our case will result in a significant underestimation of the decline in the productivity of world health production we do not find evidence supporting the hypothesis that production frontiers differ between organization for economic cooperation and development oecd and non oecd countries however the change in productivity and scale elasticity do vary significantly between these countries

financial development investment and economic growth zhenhui xu in this article i use a multivari ate vector autoregressive var approach to examine the effects of permanent financial development on domestic investment and output in 41 countries between 1960 and 1993 the var approach permits the identification of the long term cumulative effects of financial development on the domestic variables by allowing for dynamic interactions among these variables the results reject the hypothesis that financial development simply follows economic growth and has very little effect on it instead there is strong evidence that financial development is important to growth and that investment is an important channel through which financial development affects growth jel e22 e44 e47 016 057 keywords economic growth financial development investment vector auto regression impulse response i introduction interest in the relationship between financial development and economic growth dates back to early this century and has been growing since the 1980s 1 in the literature three views have emerged concerning the potential importance of finance in economic growth the first sees finance as a critical element of growth schumpeter 19113 goldsmith 19691 mckinnon 19733 shaw 1973 fry 1978 1988 bencivenga and smith 1991 king and levine 1993a 1993b in this view services provided by the financial system are essential for growth and a repressed financial system characterized by price distortion undersaving negative or unstable returns on savings and investment and inefficient allocation of savings among competing users impedes growth 2 as the financial system develops households substitute out of unproductive tangible assets raising the total real supply of credit the quantity and quality of investment and thus the rate of economic growth in addition financial development can pro mote technological innovations and productivity growth king and levine 1993a the second view regards finance as a relatively unimportant factor in growth essentially as the handmaiden to industry and commerce robinson 19521 lucas 1988 stern 1989 in this perspective the lack of financial development is simply a manifestation of the lack of demand for financial services as the real sectors of the economy grow the demand for various financial services rises and will thus be met by the financial sector based on this view financial development simply follows economic growth and has very little effect on it like the first one the third view ascribes effects to finance but focuses on its potential negative impacts on growth van wijnbergen 1983 buffie 1984 economists holding this view contend that financial development can hinder growth by reducing available credit to domestic firms this situation arises from the presence of informal curb markets as the formal financial system develops households are seen to substitute out of curb market loans thus reducing the total real supply of domestic credit the reduction in the supply of credit can lead to a credit crunch thereby lowering investment and slowing production and growth further such a credit crunch can retard economic growth beyond the short term by lowering the steady state capital stock wijnbergen 1983 from these divergent views three testable hypotheses emerge with sharply different policy implications the first view suggests that government policies should be directed toward improving the financial system since financial development has important causal effects on growth the second view implies that government policies toward improving the financial system will have little effect on growth since financial development results from growth and has little impact on it based on the third view there is a potential danger of financial development under certain institutional arrangements government efforts toward financial development can cost an economy its long term growth by reducing total real supply of domestic credit

a survey of recent developments in the literature of finance and growth this paper provides a survey of the recent progress in the literature of financial development and economic growth the survey highlights that most empirical studies focus on either testing the role of financial development in stimulating economic growth or examining the direction of causality between these two variables although the positive role of finance on growth has become a stylized fact there are some methodological reservations about the results from these empirical studies several key issues unresolved in the literature are highlighted the paper also points to several directions for future research

efficiency measures and productivity indexes in the context of university library benchmarking data envelopment analysis dea has attracted considerable attention during the last few decades as an intuitively clear method for performance assessment theoretical developments have taken turns with empirical efficiency studies in this paper we empirically analyse performance differences across university libraries from different countries from a cross section and a longitudinal perspective we use the malmquist index approach to disentangle environmental efficiency from technical efficiency te to highlight performance differences eventually induced by environmental factors beyond the control of library management as well as to decompose productivity changes over time into changes in te and changes in technology in our cross section analysis we found that north american na libraries are more productive at higher input levels than the european libraries from germany and austria at which we looked in this contribution moreover the largest na libraries are still able to improve performance as t

aggregate health care expenditures and national income is health care a luxury good it is well known that a strong relationship exists between national expenditures on health care and national income this has been used to suggest that health care is a luxury good and that factors such as the type of health care delivery system in a country are of little importance in determining expenditure levels this paper argues that these implications rely upon the application of microeconomic analysis to macroeconomic data and that this is not appropriate as well as raising questions about the inferences drawn from previous studies new empirical evidence is presented which casts some doubts on previous findings international comparisons are based on purchasing power parity rather than exchange rate conversions underlining the importance of prices as well as quantities in the relationship and leading to the conclusion that the aggregate data show health care to be if anything a necessity rather than a luxury good

weather shocks agriculture and crime evidence from india we use detailed crime agriculture and weather data from india during the years 1971 2000 to conduct a systematic analysis of the relationship between weather shocks and multiple categories of crime we find that drought and heat exert a strong impact on virtually all types of crimes that the impact on property crimes is larger than for violent crimes and that this relationship has been relatively stable over three decades of economic development we then use seasonal and geographical disaggregations of weather and agricultural cultivation to examine the prevailing hypothesis that agricultural income shocks drive the weather crime relationship in developing countries the patterns we find are consistent with this hypothesis in the case of rainfall shocks but suggest additional mechanisms may play an important role in driving the heat crime relationship consistent with evidence from industrialized countries

credit supply and the price of housing we show that since 1994 branching deregulations in the u s have signi cantly af fected the supply of mortgage credit and ultimately house prices with deregulation the number and volume of originated mortgage loans increase while denial rates fall but the deregulation has no eect on a placebo sample formed of mortgage compa nies that should not be aected by the regulatory change this sharpens the causal interpretation of our results deregulation acts to relax access to mortgage credit and pushes the demand for house ownership outwards interestingly the fraction of securi tized mortgage loans remains unchanged through the process we nd evidence house prices rise with branching deregulation and particularly in metropolitan areas where construction is inelastic for topographic reasons we document these results in a large sample of counties across the u s we also focus on a reduced cross section formed by counties on each side of a state border where a regression discontinuity approach is possible our conclusions are strengthened jel classi cation numbers g21 g10 g12

exchanging goods and damages the role of trade on the distribution of climate change costs the impacts of climate change vary significantly across world regions whereas tropical and subtropical regions are expected to suffer severely from the effects of climate change the impacts in northern latitudes should remain relatively moderate however regions are not self sufficient and the costs of climate change can spread across regions through international trade i study the international spillover of climate impacts within a regionalised climate sensitive dynamic computable general equilibrium model of the world economy using data from a global climate model shows that the world regions face welfare losses between 0 6 and 2 1 due to climate change i also show that climate change affects terms of trade and sectoral competitiveness by means of a decomposition method the extent of spillover impacts through international trade can be identified spillover impacts significantly affect either positively or negatively the total costs of climate change for a region for regions with low exposure to climate change and high adaptive capacities spillover effects are responsible for a 1 6 of the total cost of climate change

wealthier is healthier we estimate the effect of income on health using cross country timeseries data on health infant and child mortality and life expectancy and income per capita we use instrumental variables estimates using exogenous determinants of income growth to identify the pure income effect on health isolated from reverse causation or incidental association the long run income elasticity of infant and child mortality in developing countries lies between 0 2 and 0 4 using these estimates we calculate that over a half a million child deaths in the developing world in 1990 alone can be attributed to the poor economic performance in the 1980s

income shocks and hiv in africa we examine how variation in local economic conditions has shaped the aids epidemic in africa using data from over 200 000 individuals across 19 countries we match biomarker data on individuals serostatus to information on local rainfall shocks a large source of income variation for rural households we estimate infection rates in hiv endemic rural areas increase by 11 for every recent drought an effect that is statistically and economically significant income shocks explain up to 20 of variation in hiv prevalence across african countries suggesting existing approaches to hiv prevention could be bolstered by helping households manage income risk better the relationship between income and health has long been of interest to economists and a lengthy literature documents strong linkages between economic conditions and many important health outcomes currie 2009 there has been much less progress however in understanding the economic foundations of the hiv aids epidemic one of the most important global health challenges such an understanding might yield particular dividends in sub saharan africa ssa where over a million people continue to become newly infected with the disease each year unaids 2010 in this article we explore the role of negative income shocks in shaping the

the financial cycle and macroeconomics what have we learnt abstract it is high time we rediscovered the role of the financial cycle in macroeconomics in the environment that has prevailed for at least three decades now it is not possible to understand business fluctuations and the corresponding analytical and policy challenges without understanding the financial cycle this calls for a rethink of modelling strategies and for significant adjustments to macroeconomic policies this essay highlights the stylised empirical features of the financial cycle conjectures as to what it may take to model it satisfactorily and considers its policy implications in the discussion of policy the essay pays special attention to the bust phase which is less well explored and raises much more controversial issues

implicit bank debt guarantees costs benefits and risks the expectation by market participants that public authorities might bailout the creditors of banks that are considered too important for financial system stability or another reason to be allowed to fail is commonly referred to as an implicit guarantee public authorities do not have any explicit commitment to intervene they may even honestly state that they not want to do so ex ante but may feel compelled to do so ex post a declared policy aim is to limit the value of implicit guarantees by making banks stronger more easily resolvable in case of distress as well as by imposing extra charges that rise as banks become more systemically important as part of the latter approach globally systemically important banks are identified and subjected to more costly and intrusive regulation there is little evidence that specific approach has been successful so far there is some evidence that the introduction of new resolution frameworks has been helpful while the use of newly available resolution tools and the involvement of bank creditors in the burden sharing associated with bank failure resolution has significantly reduced the value of implicit bank debt guarantees where it occurred in that sense actions speak louder than words

financial development and economic growth abstract this paper examines the empirical relationship between long run growth and financial development proxied by the ratio between bank credit to the private sector and gdp we find that this proxy is positively correlated with growth in a large cross country sample but its impact changes across countries and is negative in a panel data for latin america we argue that the latter findings is the result of financial liberalization in a poor regulatory environment our findings also show that the main channel of transmission from financial development to growth is the efficiency rather than the volume of investment

studying the effects of household and firm credit on the trade balance the composition of funds matters i introduction the implications of higher levels of financial development have been investigated in a large number of studies both in the empirical growth and in the financial crisis literatures 1 a widely used indicator of financial development is the relative importance of loans issued by commercial banks and other financial intermediaries to the entire private sector that is the private credit to gross domestic product gdp ratio following the definition by king and levine 1993a 1993b a higher level of private credit indicates better developed financial markets and easier credit access for businesses and households yet these two types of borrowers vary in terms of the use of credit and might have different effects on macroeconomic performance in this article we study the link between the components of private credit and the trade balance we focus on the distinction between household and corporate sector credit and investigate whether these two types of credit have adverse effects on the trade balance of goods and services this article builds on a theoretical framework by backus kehoe and kydland 1994 who study the dynamics of the trade balance we extend their work by assuming two types of households one being credit constrained due to enforcement problems we then ease the credit constraints on households and firms and study the hypothesized effects by comparative statics analysis more specifically we argue that an increase in household credit raises the demand for consumption goods whereas firm credit growth raises the demand for investment goods while both can have a negative impact on the trade balance the difference is important because borrowing to finance consumption does not add to the productive capacity of an economy and to greater export earnings frankel and rose 1996 firm credit on the other hand has the potential to increase investment by relaxing the credit constraints on firms thus increasing exports and trade balance exploring the decomposition of private credit in emerging countries is relevant for several reasons first the effects of the increased level of household credit in emerging economies are still ambiguous on the one hand better access to credit helps credit constrained households to smooth out their consumption on the other hand it boosts spending and hence decreases savings in an influential paper japelli and pagano 1994 show that liquidity constraints on households raise the saving rates they also find empirical evidence that an increase in household credit decreases saving rates for a sample of organization for economic cooperation and development oecd countries yet the effects of household credit in emerging economies have not been explored second if we find that household and firm credit have different impacts on the trade balance of goods and services this underlines the importance of the decomposition of private credit which will also have key implications for the financial development growth link the level of private credit in emerging economies has been rising steadily after the financial liberalization process that took place in early 1990s however higher levels of total private credit do not necessarily imply higher levels of firm credit in fact data for emerging economies show that household credit rather than firm credit has been rapidly increasing in the past decade the higher share of household credit in the total private credit can crowd out investment especially in countries where stock and bond markets are not well developed to finance investment finally a possible negative link between household credit and trade balance has important policy implications for emerging economies as argued by wood 1997 the international monetary fund continues to place most emphasis within its programmes on the stabilisation objective and therefore the core of imf programmes continues to be based upon the restriction of domestic credit creation

what do we learn from the weather the new climate economy literature a rapidly growing body of research applies panel methods to examine how temperature precipitation and windstorms influence economic outcomes these studies focus on changes in weather realizations over time within a given spatial area and demonstrate impacts on agricultural output industrial output labor productivity energy demand health conflict and economic growth among other outcomes by harnessing exogenous variation over time within a given spatial unit these studies help credibly identify i the breadth of channels linking weather and the economy ii heterogeneous treatment effects across different types of locations and iii nonlinear effects of weather variables this paper reviews the new literature with two purposes first we summarize recent work providing a guide to its methodologies datasets and findings second we consider applications of the new literature including insights for the damage function within models that seek to assess the potential economic effects of future climate change jel c51 d72 o13 q51 q54

credit cycle coherence in the eurozone was there a euro effect this paper examines effects of the euro introduction on credit cycle coherence in the eurozone through six channels we construct and describe credit cycles for total bank credit household mortgages and non financial business loans for 16 emu economies over 1990 2015 credit cycle coherence is measured by synchronicity of cycle movements and similarity of their amplitudes we find that the effect of euro introduction runs through elimination of currency risk and higher capital flows which decrease coherence of total credit and mortgage credit cycles but increase coherence of business credit cycles falling interest rates contribute to the convergence of total and mortgage credit cycles financial deregulation and legal harmonization are associated with lower coherence of all credit cycles while trade openness has the opposite impact the findings impinge on monetary policy effectiveness in the eurozone with implications for macroprudential policy

the finance growth nexus in crisis while the literature on the finance growth nexus suggests a positive link between financial development and economic growth another strand of literature highlights the crucial role of credit growth for the occurrence and strength of financial and economic crises in this paper we link the two seemingly contradicting strands of the literature by a strong and robust empirical finding while financial development is indeed positively linked to gdp p c growth in normal non crisis times larger financial sectors lead to significantly worse economic outcomes in the case of a banking crisis

empirical studies on agricultural impacts and adaptation abstract agricultural production is heavily dependent on weather outcomes and hence climate change has the potential to significantly alter the sector s productivity both reduced form studies as well as integrated assessment models have found that the agricultural sector might experience significant impacts we discuss the advantages of empirical reduced form studies and their link and potential usefulness to integrated assessment models we further discuss challenges facing empirical studies and recent research that looks at the longer term changes in climate and attempts to measure adaptation

a new database on the structure and development of the financial sector this article introduces a new database of indicators of financial structure and financial development across countries and over time the database is unique in that it combines a wide variety of indicators that measure the size activity and efficiency of financial intermediaries and markets it improves on previous efforts by presenting data on the public share of commercial banks introducing indicators of the size and activity of nonbank financial institutions and constructing measures of the size of bond and primary equity markets this article introduces a new database the first to provide comprehensive measures of the development structure and performance of the financial sector this database is the first to define and construct indicators of the size and activity of nonbank financial intermediaries such as insurance companies pension funds and non deposit money banks it is also the first to include indicators of the size of primary equity markets and primary and secondary bond markets in constructing the database authors carefully deflate measures and match stock and flow variables

the african growth miracle measures of real consumption based on the ownership of durable goods the quality of housing the health and mortality of children the education of youths and the allocation of female time in the household indicate that sub saharan living standards have for the past two decades been growing about 3 4 3 7 percent per year that is three and a half to four times the rate indicated in international data sets

credit booms and lending standards evidence from the subprime mortgage market this paper links the u s subprime mortgage crisis to demand side factors that contributed to the rapid expansion of the u s mortgage market we show that denial rates were relatively lower in areas that experienced faster credit demand growth and that lenders in these high growth areas attached less weight to applicants loan to income ratios the results are robust to controlling for supply side factors including house price appreciation mortgage securitization and other economic fundamentals and to several robustness tests controlling for endogeneity the results are consistent with the notion that a relaxation of lending standards triggered by an increased demand for loans contributed to the boom and the ensuing crisis together with other supply side explanations these findings shed new light on the relationship between credit booms and financial instability

natural disasters and countries exports new insights from a new and an old database this paper is the first to uncover in details the impact of different families of disasters on exports from 1979 to 2000 storms floods earthquakes and changes in temperatures besides our paper is the first to compare in a quasi systematic way the results across the two data sets at hand the standard em dat data and geomet data a newly available data set based on geophysical and meteorological data european economic review 2013 58 18 journal of development economics 2014 111 92 we run series of regressions while accounting progressively for the characteristics of products all traded goods v s agriculture ones the characteristics of the country size level of development and the intensity of the catastrophes when pooling all countries and all types of disasters we do not find any statistical impact on exports but when focusing on each of them separately and on agricultural goods the occurrence of an earthquake appears to reduce exports of about 3 regardless of its location a windstorm shock even when it happens to be very severe has hardly any impact a flood on its side is estimated to reduce export flows of a small country by nearly 3 the effect of changes in temperatures is ambiguous all in all except for temperature related disasters the results are consistent across both data sets em dat and geomet although they appear to be slightly more in line with our expectations in the case of geomet

do capital flows change domestic credit allocation since the 1990s domestic bank credit has been reallocated away from lending to non financial business and toward households an expanding literature discusses negative effects on growth and stability of this change in credit allocation we research its drivers we hypothesize that if foreign capital flows into economies with few investment opportunities it may substitute for domestic bank lending to non financial business so that bank balance sheets become more dominated by household lending in gmm estimations on data for 36 economies over 1990 2011 we find evidence consistent with this mechanism foreign capital inflows into the non bank sector but not into the bank sector are associated with lower shares of business lending in domestic bank portfolios the association is weaker in economies with more investment opportunities whether proxied by investment shares current account surpluses or emu membership our results highlight the importance of sectoral destination in determining the effects of capital flows

non linear growth effects of financial development does financial integration matter using both macro and industry level data this paper analyses the non linear effects of financial development and international financial integration on economic growth in europe special attention is devoted to modeling threshold effects with respect to the depth of financial markets as a measure of economies absorption capacity results reveal evidence of significant non linear effects with less developed european countries gaining more from financial development in contrast benefits of international financial integration become significant at higher levels of financial development the data show that monetary integration in europe significantly contributed to a higher degree of financial integration entry of new eu members to the european monetary union may thus be the mechanism ensuring a virtuous development circle as the adoption of the euro may allow the development of domestic financial markets and financial integration to go hand in hand

on the role of domestic and international financial cyclical factors in driving economic growth abstractwe investigate the effects of domestic and international financial cyclical factors on the us business cycle over the period 1890 2013 using an augmented stochastic version of the neoclas

implicit bank debt guarantees costs benefits and risks implicit bank debt guarantees the expectation by market participants that public authorities might bailout the creditors of banks that are considered too important for financial system stability or another reason to be allowed to fail is commonly referred to as an implicit guarantee public authorities do not have any explicit commitment to intervene they may even honestly state that they not want to do so ex ante but may feel compelled to do so ex post a declared policy aim is to limit the value of implicit guarantees by making banks stronger more easily resolvable in case of distress as well as by imposing extra charges that rise as banks become more systemically important as part of the latter approach globally systemically important banks are identified and subjected to more costly and intrusive regulation there is little evidence that specific approach has been successful so far there is some evidence that the introduction of new resolution frameworks has been helpful while the use of newly available resolution tools and the involvement of bank creditors in the burden sharing associated with bank failure resolution has significantly reduced the value of implicit bank debt guarantees where it occurred in that sense actions speak louder than words

an econometric analysis of health care expenditure a cross section study of the oecd countries this paper is an empirical examination of the determinants of aggregate health care expenditure the paper presents a systematic analysis of relationships across 19 oecd countries showing the effects of aggregate income institutional and socio demographic factors on health care expenditure the results indicate that institutional factors of the health systems in addition to per capita gross domestic product gdp contribute significantly to the explanation of the health care expenditure variation between countries for example the way physicians in outpatient care are paid and the mixture of public private funding and inpatient outpatient care

gains from trade and the sovereign bond market abstract increasing international flows of goods services and financial assets have been shown to increase a country s welfare through various channels this paper studies how a country s access to a bond market affects its welfare gains from international trade we do so by incorporating a sovereign bond market into a simple armington 1969 s trade model while standard trade models suggest surprisingly small gains from trade our model implies that introducing channels through a sovereign bond market greatly magnifies the gains from trade key mechanisms in the model are confirmed by data and the results are found to be robust to a variety of considerations

what is happening to the impact of financial deepening on economic growth i introduction among the strongest elements of the modern economists canon is that financial sector development has a significant impact on economic growth a generation ago economists like goldsmith 1969 1 and mckinnon 1973 began to draw attention to the benefits of financial structure development and financial liberalization by the early 1990s mckinnon 1991 12 could write with confidence that now however there is widespread agreement that flows of saving and investment should be voluntary and significantly decentralized in an open capital market at close to equilibrium interest rates since the 1990s a burgeoning empirical literature has illustrated the importance of financial sector development for economic growth despite the growing consensus however we find that the link between finance and growth in cross country panel data has weakened considerably over time at the very time that financial sector liberalization spread around the world the influence of financial sector development on economic growth has diminished the seminal empirical work that established the growth finance link is king and levine 1993 which extended the cross country framework introduced in barro 1991 by adding financial variables such as the ratios of liquid liabilities or claims on the private sector to gross domestic product gdp to the standard growth regression they found a robust positive and statistically significant relationship between initial financial conditions and subsequent growth in real per capita incomes for a cross section of about 80 countries in the subsequent decade numerous empirical studies expanded upon this using both cross country and panel data sets for the post 1960 period 2 in this paper we reexamine the core cross country panel result and find that the impact of financial deepening on growth is not as strong with more recent data as it appeared in the original panel studies with data for the period from 1960 to 1989 we consider various explanations for this clear shift first we suggest that financial deepening has a positive effect on growth if not done to excess rapid and excessive deepening as manifested in a credit boom can be problematic even in the most developed markets because it can both weaken the banking system and bring inflationary pressures we test this hypothesis by looking at the finance growth nexus among countries that have or have not experienced financial sector crises we find that once crisis episodes are removed the finance growth relationship remains intact its weakening over time thus seems to be a result of an increased incidence of crises in later years our second and related hypothesis is that the widespread liberalization of financial markets that occurred in the late 1980s and early 1990s made financial deepening less effective this is reminiscent of robert lucas s 1975 critique of econometric policy evaluation advanced three decades ago policies that have promoted and or forced increases in financial depth over the past two decades may have altered the basic structural relationship between finance and growth this could occur if the observed benefits of financial deepening led many countries to liberalize before the associated legal and regulatory institutions were sufficiently well developed as a consequence the impact of financial deepening on growth would become smaller our evidence does not indicate that recent liberalizations are responsible for the breakdown of the finance growth link however there may be an indirect link as premature financial development can lead to financial crises that have real effects third we examine the role of global equity markets that have grown in importance and prominence in the years over which the finance growth relationship disappeared however we do not find any evidence to suggest that equity market growth has substituted for the role of credit markets and banks in particular

towards an accounting view on money banking and the macroeconomy history empirics theory in this paper three views are considered which are traditionally associated with money cranks and brave heretics the first is that the credit nature of money has macroeconomic significance the second is that financial development can be bad for economic growth the third is that macroeconomic models need to be explicitly monetary macroeconomic models it is argued that in each of these three areas there has been a recent shift in mainstream economic opinion this suggests new opportunities for meaningful debate between heterodox and orthodox schools on money and finance it is further argued following skaggs 2003 that a common meeting ground could be an accounting view of economics this is a mode of macroeconomic analysis which explicitly uses accounting definitions identities that credit is also debt or that flows of a variable affect the stock of that variable or accounting methods e g decomposing different kinds of liabilities or linking flows of liquidity to flows of transactions to structure and direct the analysis the accounting view is highly pluralist yet clearly defined i discuss its applications to each of the three views

financialisation and the slowdown of accumulation over the past decades financial investment of non financial businesses has been rising and accumulation of capital goods has been declining the first part of the paper offers a novel theory to explain this phenomenon financialization the shareholder revolution and the development of a market for corporate control have shifted power to shareholders and thus changed management priorities leading to a reduction in the desired growth rate in the second part the link between accumulation and financialization is tested econometrically by means of a time series analysis of aggregate business investment for usa uk france and germany extensive test of robustness are performed for the first three countries evidence that confirms the negative effect of financialization on accumulation is found author s abstract

public financing of health expenditures insurance and health outcomes the effects of public financing of health expenditures insurance coverage and other factors on health outcomes are examined within health production models estimated using 1960 1992 data across 20 oecd countries mortality rates are found to depend on the mix of health care expenditures and the type of health insurance coverage increases in the publicly financed share of health expenditures are associated with increases in mortality rates increases in inpatient and ambulatory insurance coverage are associated with reduced mortality the effects of gdp health expenditures and age structure on mortality are similar to those in previous studies tobacco use alcohol use fat consumption female labour force participation and education levels are also significantly related to overall mortality rates increases in income inequality are associated with lower mortality rates suggesting that the negative relationship between inequality and health outcomes suggested by some previous studies does not remain w

the determinants and effects of health expenditure in developed countries previous studies of international differences in health spending have been restricted to the use of relatively small samples of cross sectional data our objective here is to re examine the results of previous work using a sample of 560 pooled time series and cross section observations results confirm the importance of gdp as a determinant of health spending with an estimated income elasticity at or around unity but also suggest that oecd countries should not be regarded as a single homogeneous group the importance of some non income variables is also confirmed although the direct effect of these factors appears to be small

how effective is public health expenditure in improving overall health a cross country analysis the primary emphasis of this paper is on seeking some justification for the worldwide phenomenon of increasing government involvement in health care the disability adjusted health expectancy dale rankings of countries in the world health report 2000 ranked wealthier countries with a typically large public sector involvement in health care higher on the list contrary to the possible implications for this ranking this paper finds that the comparatively higher dale in wealthier countries is not a result of greater public health expenditures in the middle income and less developed countries however there is some evidence of effective public involvement in health care

does one size fit all a reexamination of the finance and growth relationship abstract recent research has found a strong positive effect of a country s financial development on economic growth we propose that this relationship may vary according to the level of financial development divided in three regions in the low region countries with very low levels of financial development additional improvements in financial markets have an uncertain effect on growth in the intermediate region financial development has a large positive effect on growth finally in the high region the effect is positive but smaller we examine a panel of 74 countries using generalized method of moments gmm dynamic panel techniques and find support for the different regions

the effect of financial development on convergence theory and evidence we introduce imperfect creditor protection in a multicountry schumpeterian growth model the theory predicts that any country with more than some critical level of financial development will converge to the growth rate of the world technology frontier and that all other countries will have a strictly lower long run growth rate we present evidence supporting these and other implications in the form of a cross country growth regression with a significant and sizable negative coefficient on initial per capita gdp relative to the united states interacted with financial intermediation in addition we find that other variables representing schooling geography health policy politics and institutions do not affect the significance of the interaction between financial intermediation and initial per capita gdp and do not show any independent effect on convergence in the regressions our findings are robust to removal of outliers and to alternative conditioning sets estimation procedures and measures of financial development

estimating a health production function for sub saharan africa ssa the paper estimates a health production function for sub saharan africa based on the grossman 1972 theoretical model that treats social economic and environmental factors as inputs of the production system in estimating this function socioeconomic and environmental factors such as income per capita illiteracy rate food availability ratio of health expenditure to gdp urbanization rate and carbon dioxide emission per worker are specified as determinants of health status the parameters of the function are estimated by one way and two way fixed and random effects model of panel data analyses the results of the two way random effect model suggest that an increase in income per capita a decrease in illiteracy rate and an increase in food availability are strongly associated with an improvement in life expectancy at birth overall the results imply that a health policy which may focus on the provision of health services family planning programs and emergency aids to the exclusion of other socio

finance and the sources of growth the authors evaluate whether the level of development in the banking sector exerts a causal impact on economic growth and its sources total factor productivity growth physical capital accumulation and private saving they use 1 a pure cross country instrumental variable estimator to extract the exogenous component of banking development and 2 a new panel technique that controls for country specific effects and endogeneity they find that banks do exert a large causal impact on total factor productivity growth which feeds through to overall gdp gross domestic product growth the long run links between banking development and both capital growth and private savings are more tenuous

reassessing the law finance and growth nexus after the recent great recession abstract the paper provides a reassessment of the relationship between financial structure financial development and economic growth conducting cross section and panel econometric analyses for a sample of 62 countries over 1980 2016 in line with the traditional literature we confirm the existence of a positive cross country relationship between the legal system financial development and growth even including the experience of the recent great recession in addition when jointly assessing the effect of financial structure and financial development on growth it emerges that a more bank oriented economy enjoys higher benefits in terms of long run real gdp per capita growth than a market oriented one when we consider variations across countries and over time we find that both financial structure and financial development affect growth but in an opposite way as the cross section analysis in particular when we control for their joint effect on growth we observe a positive impact of market based financial systems and a negative impact of the overall financial development we also provide evidence of the existence of a positive and significant relationship between economic growth and shadow banking during the 2002 2016 period highlighting the crucial role played by non bank financial intermediation in complementing traditional banking and in affecting the real economy

the migration response to increasing temperatures climate change especially the warming trend experienced in recent years by several countries could affect agricultural productivity as a consequence the income of rural populations will change and with it the incentives for people to remain in rural areas using data from 115 countries between 1960 and 2000 we analyze the effect of differential warming trends across countries on the probability of either migrating out of the country or from rural to urban areas we find that higher temperatures in middle income economies increased migration rates to urban areas and to other countries in poor countries higher temperatures reduced the probability of migration to cities and to other countries consistently with the presence of severe liquidity constraints in middle income countries migration represents an important margin of adjustment to global warming potentially contributing to structural change and even increasing income per worker such a mechanism however does not seem to work in poor economies
