effects of quotas under variable returns to scale the large country case the welfare effects of import quotas have been studied by a host of trade theorists see for example dei 8 brecher and bhagwati 3 and neary 20 recently chao hwang and yu 4 have examined the welfare impacts of quotas under variable returns to scale vrs for a small home economy the purpose of this paper is to consider the welfare effects of quotas under vrs in a two country trading world the large country case for both the home as well as the foreign country specifically we will explore the conditions under which a quota can benefit either the home country the foreign country or both countries in addition we will derive and interpret a formula for computing the second best quota in the presence of vrs

the drivers of international migration to the uk a panel based bayesian model averaging approach a heterogeneous panel based bayesian model averaging approach is used to identify the robust economic and policy drivers of international migration to the uk from 14 different source regions over 1980 2007 around three quarters of the increase in net immigration over the last decade which is particularly pronounced for selected source regions is associated with structural change which may be attributed to uk and foreign immigration policy the remainder of the rise is largely explained by friends and family effects there are considerable uncertainties associated both with the effects of particular economic drivers of immigration and with forecasts of immigration

the dynamic relationship between the us gdp imports and domestic production of crude oil this article investigates the dynamic relationship between crude oil imports gross domestic product gdp and domestic crude oil production of the united states using a vector error correction model estimation generalized impulse response functions persistence profile and variance decompositions this article results suggest that the gdp has a leading role in determining oil imports

nonmonetary effects of the financial crisis in propagation of the great depression this paper examines the effects of the financial crisis of the 1930s onthe path of aggregate output during that period our approach is complementary to that of friedman and schwartz who emphasized the monetary impact of the bank failures we focus on non monetary primarily credit related aspects of the financial sector output link and consider the problems of debtors as well as those of the banking system we argue that the financial disruptions of 1930 33 reduced the efficiency of the credit allocation process and that the resulting higher cost and reduced availability of credit acted to depress aggregate demand evidence suggests that effects of this type can help explain the unusual length and depth of the great depression this abstract was borrowed from another version of this item

a micro data approach to the identification of credit crunches this article presents a micro data approach to the identification of credit crunches using a survey among german firms which regularly queries the firms assessment of the current willingness of banks to extend credit we estimate the probability of a restrictive loan supply policy by time taking into account the creditworthiness of borrowers creditworthiness is approximated by firm specific factors e g the firms assessment of their current business situation and their business expectations after controlling for the return on the banks risk free investment alternative which is also likely to affect the supply of loans we derive a credit crunch indicator which measures that part of the shift in the loan supply that is neither explained by firm specific factors nor by the opportunity costs of providing risky loans

climate change policy what do the models tell us very little a plethora of integrated assessment models iams have been constructed and used to estimate the social cost of carbon scc and evaluate alternative abatement policies these models have crucial flaws that make them close to useless as tools for policy analysis certain inputs e g the discount rate are arbitrary but have huge effects on the scc estimates the models produce the models descriptions of the impact of climate change are completely ad hoc with no theoretical or empirical foundation and the models can tell us nothing about the most important driver of the scc the possibility of a catastrophic climate outcome iam based analyses of climate policy create a perception of knowledge and precision but that perception is illusory and misleading jel c51 q54 q58

gains from trade under variable returns to scale recently several trade theorists have investigated the welfare consequences of international trade under variable returns to scale for example kemp and negishi 11 using the revealed preference arguments obtain the sufficient conditions under which the opening of trade and an improvement in the terms of trade are nonharmful in the presence of variable returns to scale production subsidies and consumption taxes eaton and panagariya 7 reexamine these issues in the context of pareto welfare criterion it is noteworthy that the assumption of constant returns to scale is retained in their discussions on production subsidies and consumption taxes 1 the purpose of this paper is to explore the welfare implications of tariffs and consumption taxes as well as the welfare rankings of these policy instruments under variable returns to scale we obtain several interesting results for example social welfare for a small country can be maximized by introducing in addition to free trade a policy of production tax cum subsidy such that the output of the industry exhibiting greater smaller returns to scale is pushed to the maximum minimum a higher tariff rate needs not result in a lower welfare whereas a higher rate of consumption tax necessarily leads to a lower welfare furthermore a tariff may be superior to an equivalent consumption tax the paper evolves as follows the model and assumptions are presented in section ii section iii is the analysis regarding non optimality of free trade free trade versus no trade

is the relationship between financial development and economic growth monotonic evidence from a sample of middle income countries summary we revisit the relationship between financial development and economic growth in a panel of 52 middle income countries over the 1980 2008 period using pooled mean group estimations in a dynamic heterogeneous panel setting we show that there is an inverted u shaped relationship between finance and growth in the long run in the short run the relationship is insignificant this suggests that too much finance can exert a negative influence on growth in middle income countries the finding of a non monotonic effect of financial development on growth is confirmed by estimating a threshold model

prudential regulation and the credit crunch evidence from japan the underlying causes of sharp declines in bank lending during recessions in large developed economies as exemplified by the u s in the early 1990s and japan in the late 1990s are still being debated due to the lack of any convincing identification strategy of the supply side capital lending relationship from lending demand using within bank share of real estate lending in the late 1980s as an instrumental variable for bank capital we find that japanese banks cut back on their lending in response to a large loss of bank capital in fiscal year 1997

the growth effects of tax rates in the oecd this paper explores the merits of macro and micro based tax rate measures within an open economy fiscal policy and growth model using annual data for 15 oecd countries we find statistically small non robust long run growth effects of macro based average tax rates on capital income and consumption but some evidence for average labor income tax effects changes in micro marginal income tax rates at both the personal and corporate levels yield statistically robust gdp responses of modest size both domestic and foreign corporate taxes appear relevant in general tax effects on gdp operate largely via factor productivity rather than factor accumulation

zombie lending and depressed restructuring in japan this paper explores the role that misdirected bank lending played in prolonging the japanese macroeconomic stagnation that began in the early 1990s the investigation focuses on the wide spread practice of japanese banks of continuing to lend to otherwise insolvent firms we docu ment the prevalence of this forbearance lending and show its distorting effects on healthy firms that were competing with the impaired firms the paper by hoshi 2000 was the first to call attention to this phenomenon and its ramifi

renewable energy consumption economic growth nexus in turkey abstract this paper examines the renewable energy consumption economic growth causality nexus in turkey studies in the literature can be grouped as country specific and multi country studies the results of these studies are inconsistent and there is no agreement on the existence or the direction of causality between renewable energy consumption and economic growth the results of this country specific study support conservation hypothesis the results of empirical tests from ardl approach show that renewable energy consumption has a negative impact on economic growth and the ones of toda yamamoto causality tests show that there is a unidirectional causality running from economic growth to renewable energy consumption

financial development financial fragility and growth the authors study the apparent contradiction between two strands of the literature on the effects of financial intermediation on economic activity on the one hand the empirical growth literature finds a positive effect of financial depth as measured by for instance private domestic credit and liquid liabilities for example levine loayza and beck 2000 on the other hand the banking and currency crisis literature finds that monetary aggregates such as domestic credit are among the best predictors of crises and their related economic downturns for example kaminski and reinhart 1999 the authors account for these contrasting effects based on the distinction between the short and long run impacts of financial intermediation working with a panel of cross country and time series observations they estimate an encompassing model of short and long run effects using the pooled mean group estimator developed by pesaran shin and smith 1999 their conclusion from this analysis is that a positive long run relationship between financial intermediation and output growth coexists with a mostly negative short run relationship the authors further develop an explanation for these contrasting effects by relating them to recent theoretical models by linking the estimated short run effects to measures of financial fragility namely banking crises and financial volatility and by jointly analyzing the effects of financial depth and fragility in classic panel growth regressions

from riches to rags and back institutional change financial development and economic growth in argentina since 1890 abstractargentina is the only country in the world that in 1900 was developed and in 2000 was developing although economic historians have identified and explored various possible explanations chiefly institutions political instability financial development inflation trade openness and international financial integration no study so far has attempted a comprehensive quantitative assessment of their relative importance this article tries to fill this gap using the power arch framework and annual data since 1896 to study the effects of these factors in terms of both growth and growth volatility the results highlight two main factors to understand the remarkable growth trajectory of argentina over the very long run financial development and institutions formal and informal political instability and stress the importance of differences in their short vis a vis long run behaviour

country size and exchange rates this paper studies how country size affects the role of the exchange rate in external adjustment first the impact of country size on the sensitivity of relative prices to external imbalances is explored in a two country neoclassical model second at the empirical level a significant effect of external imbalances on relative prices is found in particular a trade surplus is associated with a depreciation of the real exchange rate our estimations reveal a systematic pattern in the sensitivity of the real exchange rate to external imbalances larger countries are characterized by a higher absolute trade elasticity of the exchange rate

the adaptive investment effect evidence from chinese provinces abstract this paper investigates the adaptive investment effect a redirection of investment towards adaptive capital in order to mitigate the negative effects of climate change we find that the impact of investment on economic growth is reduced by between 27 and 37 in chinese provinces investing more in adaptive capital this implies that the benefits from mitigation policies are greater than existing studies suggest

the international transmission of financial shocks the case of japan one of the more dramatic financial events of the late 1980s and early 1990s was the surge in japanese stock prices that was immediately followed by a very sharp decline of more than 50 percent while the unprecedented fluctuations in japanese stock prices were domestic financial shocks the unique institutional characteristics of the japanese economy produce a framework that is particularly suited to the transmission of such shocks to other countries through the behavior of the japanese banking system the large size of japanese bank lending operations in the united states enables us to use u s banking data to investigate the extent to which this domestic japanese financial shock was transmitted to the united states as well as to identify a supply shock to u s bank lending that is independent of u s loan demand we find that binding risk based capital requirements associated with the decline in the japanese stock market resulted in a decline in commercial lending by japanese banks in the united states that was both economically and statistically significant this finding has added importance given the severe real estate loan problems currently faced by japanese banks how japanese bank regulators decide to resolve these problems will have significant implications for credit availability in the united states as well as in other countries with a significant japanese bank presence

public budgetary rules and gdp growth an empirical study on oecd and twelve european countries we study the long term effects of budgetary rules on gdp growth rate and analyse the determinants of the short term gdp growth dynamics for both a sample of 19 oecd and a subsample of 12 european countries we show that in the long run improvements in the cyclically adjusted budget balance as well as increases in the tax burden have negative effects on gdp growth the highest effect of fiscal policy on gdp growth would be obtained if the structural deficits were used to increase the market size by reducing the tax burden in line with barro 1990 a deficit financed reduction of tax burden has a stronger effect for european than for oecd countries because in europe the government size with respect to market size is too large therefore if gdp growth is a dominant policy objective in europe specific actions should redress the 2012 treaty toward a reduction of the tax burden

the harris todaro model and economies of scale the authors attempt to reanalyze the harris todaro migration model in the presence of economies of scale in the manufacturing sector focusing on economies of scale that are external to a given firm but internal to the industry annotation

the capital crunch neither a borrower nor a lender be the dramatic reduction in the growth rate of bank lending associated with the 1990 91 recession particularly in new england has evoked claims by many observers of a credit crunch however because of the difficulty in determining whether the observed slow credit growth is a demand or supply phenomenon convincing evidence of the practical importance of credit crunches for economic activity remains elusive we overcome this obstacle by examining a cross section of banks in new england that have experienced the same economic downturn effectively controlling for changes in demand we find empirical support for a capital crunch whereby poorly capitalized institutions shrink to satisfy capital requirements this alone is not a sufficient condition for a credit crunch however we find s6me additional evidence that the ca ital crunch may have limited credit availability in new england

capital requirements monetary policy and aggregate bank lending theory and empirical evidence capital requirements linked solely to credit risk are shown to increase equilibrium credit rationing and lower aggregate lending the model predicts that the bank s decision to lend will cause an abnormal runup in the borrower s stock price and that this reaction will be greater the more capital constrained the bank i provide empirical support for this prediction the model explains the recent inability of the federal reserve to stimulate bank lending by increasing the money supply i show that increasing the money supply can either raise or lower lending when capital requirements are linked only to credit risk the motivation of this article is first to examine the impact of risk based capital requirements namely those that link mandatory capital to asset ratios for banks to their loans on aggregate bank lending these requirements called the basle capital rules or bis guidelines went into effect in march 1989 for banks in the leading industrialized nations these rules initially required banks to maintain capital equal to 7 25 percent of business and most consumer loans with the requirement increasing to 8 percent by the end of 1992 secondly i wish to understand the link between monetary policy and aggregate bank credit in the presence of risk based capital requirements my curiosity is sparked in part by two recent phenomena one is the experience of the u s economy which displayed sluggish growth during 1989 93 despite a monetary policy that attempted to spur bank lending and economic activity and the other is the striking decline in loans relative to security holdings mostly government bonds in the asset portfolios of u s

variable returns to scale urban unemployment and welfare the proposition that free trade is superior to no trade has a classical ancestry adam smith and ricardo were amongst the first proponents of free trade samuelson 26 proved and it is held by economists today that free trade is the optimal policy in the presence of standard paretoconditions it is also generally agreed amongst economists that lower trade intervention is superior to higher trade intervention given competitive conditions in a small country these propositions do not hold however in the presence of factor market imperfections such as wage differentials in a small country and therefore production or wage subsidies improves social welfare the two models which are generally used to investigate the positive as well as normative aspects of trade theory in the presence of unemployment are the uniform real minimum wage model which is based on the assumption of general rigidity of real wage in one or two sectors of production and the sector specific minimum wage model which focuses on the phenomenon of rural urban migration in the face of large scale urban unemployment these two models are commonly utilized by trade theorists to analyze trade and unemployment specifically studies by haberler 13 johnson 16 batra and seth 3 findlay 12 and brecher 6 7 investigate the consequences of rigid factor prices for a small country whereas the normative as well as positive aspects of sector specific unemployment have been explored by harris and todaro 15 bhagwati and srinivasan 4 5 and more recently by batra and naqvi 2 das 10 and kahn 19 it has been correctly observed that the introduction of an exogenously specified real minimum wage among other things generates unorthodox results concerning unemployment and gains from trade a large body of research has also been concerned with the welfare implications of different commercial policies in the context of variable returns to scale kemp and negishi 20 have pointed out the beneficial effects of trade in the presence of variable returns to scale production subsidy and consumption taxes eaton and panagariya 11 have analyzed the question of gains from trade in the presence of variable returns to scale and in the context of pareto welfare criterion whereas choi and yu 8 have examined the welfare implications of tariffs and consumption taxes as well as the welfare rankings of these policies under variable returns to scale while panagariya and succar 25 have modified the necessary and sufficient conditions for stability under increasing returns to scale in urban sector

in search of capital crunch supply factors behind the credit slowdown in japan the seeming failure of loose monetary policy to reactivate japan s economy has led some observers to suggest that the usual credit channels through which monetary policy affects the real economy are blocked and this is because of a pervasive shortage of bank capital that has induced a leftward shift in the supply of bank credit this is the so called capital crunch hypothesis this paper finds support for the hypothesis in the bank data for 1997 a year during which the landscape of the japanese financial system underwent some fundamental changes

immiserizing growth for a quota distorted small economy under variable returns to scale the authors demonstrate that growth of a small open economy distorted by import quotas in contrast to the case of tariffs improves welfare when the industries display identical variable or constant returns to scale furthermore growth cannot reduce welfare if the industry that experiences technical progress exhibits a greater returns to scale than the static industry conversely if the dynamic sector displays a smaller returns to scale than the static sector growth of a quota distorted small economy can be immiserizing the authors results are independent of whether hicks neutral technical progress occurs in the importable or the exportable sector

export share requirements and unemployment the case of quota trade restrictions such as import tariffs have been a common practice for protecting domestic import competing industries in most less developed countries ldcs foreign firms may however circumvent such protection through direct investment in the host countries this is the well known tariff jumping direct foreign investment which has been examined by brecher and diaz alejandro 7 they show that the foreign capital inflow leads to overproduction of the output of tariff protected sectors and hence results in welfare reduction recently rodrik 17 demonstrates that export share requirements when applied to the output produced by foreign capital may offset the negative effect of foreign direct investment through the contraction of tariffprotected overproduced sectors thus an increase in such a requirement may actually improve welfare this result contradicts the earlier finding of davidson matusz and kreinin 11 which is obtained from a partial equilibrium framework the existing literature on export share requirements remains deficient in two respects first the full employment models have been deployed ignoring the fact that most ldcs suffer from massive unemployment second the analysis has been confined by and large to tariff protection thereby neglecting quantitative trade restrictions e g import quotas it is noteworthy that it is quotas rather than tariffs which constitute a major constraint on imports by developing countries 2 the purpose of this paper is thus to remedy these two shortcomings by developing a sectorspecific unemployment general equilibrium model with quota restrictions on imports as noted by richardson 16 export performance requirements operate in a second best environment import

urban unemployment terms of trade and welfare it is generally accepted prior to 1970 that a deterioration in the terms of trade results in lower social welfare in particular prebisch 11 and singer 12 have expressed the basic concern with the terms of trade the secular deterioration in the terms of trade facing less developed countries ldcs leads to income and welfare losses batra and pattanaik 2 nevertheless shows that a deterioration in the terms of trade in the presence of an intersectoral wage differential may raise welfare bhagwati and brecher 5 demonstrate that a decline in the terms of trade can improve real income if capital is mobile internationally recently anam 1 obtains a similarly interesting result for an economy engaging in quota induced rent seeking activities it is notable that none of these studies considers a key feature inherent in a typical ldc namely the existence of substantial urban unemployment thus the purpose of this paper is to examine the welfare impacts of terms of trade losses for ldcs plagued by pervasive urban unemployment the well known harris todaro 7 framework of sector specific unemployment is utilized in addition we derive and contrast various welfare effects of a change in the terms of trade when a ldc pursues alternative import substitution policies i e tariffs vs quotas over the short vs the long run the paper is organized as follows section ii develops the model and provides the transformation relation between urban and rural outputs section iii examines the welfare effects of an exogenous shift in the terms of trade for a tariff or quota distorted economy in the short run as well as in the long run finally concluding remarks are set out in section iv

capital markets urban unemployment and land abstract this paper shows that the remarkable result by khan and naqvi that a reduction in the capital rental differential always improves welfare despite the presence of a rigid urban wage can be obtained only for the 2 2 harris todaro model in an extended harris todaro framework incorporating a third specific factor a decrease in a distortion may not necessarily be welfare improving

the effect of urbanization on co2 emissions in emerging economies the theories of ecological modernization and urban environmental transition both recognize that urbanization can have positive and negative impacts on the natural environment with the net effect being hard to determine a priori this study uses recently developed panel regression techniques that allow for heterogeneous slope coefficients and cross section dependence to model the impact that urbanization has on co2 emissions for a panel of emerging economies the estimated contemporaneous coefficients on the energy intensity and affluence variables are positive statistically significant and fairly similar across different estimation techniques by comparison the estimated contemporaneous coefficient on the urbanization variable is sensitive to the estimation technique in most specifications the estimated coefficient on the urbanization variable is positive but statistically insignificant the implications of these results for sustainable development policy are discussed

finance inequality nexus the long and the short of it financial development affects income inequality differently in the short and in the long term investigating oecd countries from 1870 2011 we find in the short run an improvement in financial development tends to reduce inequality while in the long run more finance contributes to more inequality the short run effect concurs with theories advocating financial development increases the availability of financial services primarily for the poor however this effect becomes nil within a few years results thus imply that policies aimed at reducing inequality through improving access of the poor to finance need to be carefully designed to ensure longevity of impact

do urbanization and industrialization affect energy intensity in developing countries abstract against a backdrop of concerns about climate change peak oil and energy security issues reducing energy intensity is often advocated as a way to at least partially mitigate these impacts this study uses recently developed heterogeneous panel regression techniques like mean group estimators and common correlated effects estimators to model the impact that income urbanization and industrialization has on energy intensity for a panel of 76 developing countries in the long run a 1 increase in income reduces energy intensity by 0 45 to 0 35 long run industrialization elasticities are in the range 0 07 to 0 12 the impact of urbanization on energy intensity is mixed in specifications where the estimated coefficient on urbanization is statistically significant it is slightly larger than unity the implications of these results for energy policy are discussed

migration and the environment policy reform in a polluted open economy previous literature on labour migration has paid little attention to the influence of environmental attributes this paper attempts to remedy this void by developing a simple two region general equilibrium model with amenities playing a key role in affecting migration flows specifically we argue that in the presence of an environmental externality interregional labour migration depends not only on wages but also on amenities people may leave a region offering higher wages if the resulting utility loss from worsened amenities exceeds the gain in wages policies should be adopted by regions or nations to regulate the environment to provide for the quality of living to attain this goal regional or international policy cooperation on tradable pollution permits can be superior to pollution permits supplied independently by each region or nation while non tradable between them

the theory of tariffs under variable returns to scale and inter industrial externalities the theory of nominal tariff in general and the well known metzler paradox in particular have been rigorously developed by metzler 14 jones 13 johnson 12 and batra 1 ch 5 among others the analysis has been typically conducted under the strong assumption that the economy is devoid of any inter industrial and or intra industrial externalities some aspects of inter industrial externalities which have played a major role in the development of welfare economics in the past three decades have been explored by chang 3 and herberg kemp and tawada 11 and the implications of intra industrial variable returns to scale which are external to the firms have been examined by eaton and panagariya 7 8 panagariya 9 parai 10 choi and yu 4 5 and beladi 2 many of the standard trade theories have been shown to be significantly affected by the presence of either type of the externalities it is notable that the implications of the externalities for the tariff theory however have not been studied the purpose of this paper thus is to examine several aspects of the standard theory of tariffs in a framework allowing various production externalities specifically we will explore the effects of a change in the tariffs and or the terms of trade on the import demand as well as the effects of tariff on the terms of trade and the domestic price ratio several interesting results emerge from this analysis for example in contrast to the conventional results an improvement in the terms of trade for a given tariff may dampen the import demand and a higher tariff for a given terms of trade may raise it an increase in the tariff rate need not improve the terms of trade and hence may raise the domestic price ratio of the importable good by more than the tariff rate although the presence of inter industrial and intraindustrial externalities does not affect the sufficient condition for the metzler paradox it does modify a necessary condition for the paradox this paper is organized as follows section ii delineates the assumptions and the model section iii examines the effects of tariffs and or the terms of trade on import demands section iv

bank capital shocks dynamic effects on securities loans and capital abstract we used quarterly data for individual banks to estimate recent dynamic responses to bank capital shocks while it took bank capital and securities only one year to adjust to capital shocks liabilities and most loan categories took two to three years to complete their adjustments compared with those in the late 1980s capital shocks were twice as large and portfolio responses to capital shocks tended to be more rapid in the early 1990s larger banks adjusted each component of their portfolios faster than smaller banks capital shocks caused banks with capital shortfalls to contract more and more quickly in the 1990s than they had in the 1980s

foreign capital inflows and welfare in an economy with imperfect competition abstract this paper examines the resource allocational and welfare effects of exogenous inflows of foreign capital in a general equilibrium model with oligopolistic competition and unemployment although the welfare impact for the short run is ambiguous and dependent upon the strength of excess profits and scale economies relative to unemployment in manufacturing in the long run additional inflows of foreign capital always improve national welfare with capital mobility hence attracting foreign capital remains a sound policy for economies characterized by imperfect competition scale economies and regional unemployment

industrialization and the demand for mineral commodities abstract this paper uses a new data set that begins in 1840 to investigate how industrialization affects the derived demand for mineral commodities i establish that there is substantial heterogeneity in the long run effect of manufacturing output on demand across five commodities a one percent increase in per capita manufacturing output leads to an approximately 1 5 percent increase in aluminum demand and a roughly 1 percent rise in copper demand estimated elasticities for lead tin and zinc are below unity my results suggest that the experience of japan and south korea s industrialization for example may be used to infer the impact of china s industrialization on future demand for metals the results imply substantial differences across commodities with regard to future demand adjustment to equilibrium takes 7 13 years which helps explain the long duration of commodity price fluctuations

sector specific minimum wages economic growth and some policy implications abstract economic growth is introduced in the urban unemployment model of harris and todaro it is shown that in the steady state the optimal savings ratio is greater than the golden rule savings ratio under full employment also the optimal proportion of total investment allocated to the urban sector is not necessarily higher than the optimal proportion under full employment

the shadow price of foreign exchange in a dual economy abstract this paper examines the shadow price of foreign exchange for a dual economy with tariffs quotas or vers we show that the shadow exchange rate is greater than the official rate in the presence of tariffs whereas it is greater or smaller than the official rate in the presence of quotas depending upon whether capital is sector specific or perfectly mobile furthermore the shadow exchange rate is unambiguously smaller than the official rate for the ver case when capital is intersectorally mobile the rate however may be larger than the official rate when capital is sector specific the practical implications of the results for project appraisal are also discussed

shocks to bank capital evidence from uk banks at home and away this article assesses how shocks to bank capital may influence a bank s portfolio behaviour using novel evidence from a uk bank panel data set from a period that predates the recent financial crisis focusing on the behaviour of bank loans we extract the dynamic response of a bank to innovations in its capital and in its regulatory capital buffer we find that innovations in a bank s capital in this precrisis sample period were coupled with a loan response that lasted up to 3 years the international presence of uk banks allows us to identify a specific driver of capital shocks in our data independent of bank lending to uk residents specifically we use write offs on loans to nonresidents to instrument bank capital s impact on uk resident lending a fall in capital brought about a significant drop in lending in particular to private nonfinancial corporations pnfc in contrast household lending increased when capital fell which may indicate that in this precrisis period banks substituted into l

institutions capital stock and wage setting in spain this article confronts two distinct perspectives of the labour market the institutionalist view highlighting equilibrium and labour market institutions and the chain reaction theory emphasizing dynamics and the growth drivers role in labour market performance we consider the ratio of public to private capital stock as a growth driver relevant to the labour market provide different economic rationales for this ratio to exert a negative influence in wage setting and explore its empirical relevance in the context of a wage setting curve for spain comprising the standard variables there are two main results first several institutional variables taken to be critical to explain unemployment in the mainstream literature are not relevant for the spanish wage setting curve second there is a negative and significant influence of the ratio of public to private capital stock which is robust to different specifications of the wage setting equation

the effects of internet usage and economic growth on co2 emissions in oecd countries a panel investigation this paper estimates the short and long run effects of internet usage and economic growth on carbon dioxide co2 emissions using oecd panel data for the period 1991 2012 the pedroni panel cointegration test confirms that the variables are cointegrated although pooled mean group pmg estimates indicate a positive significant long run relationship between internet usage and co2 emissions the coefficient is very small and no causality exists between them which both imply that the rapid growth in internet usage is still not an environmental threat for the region the study further indicates that economic growth has no significant short run and long run effects on co2 emissions internet use stimulates both financial development and trade openness the findings offer support in favor of the argument that oecd countries can promote their internet usage without being significantly concerned about its environmental consequences but the future emissions effect of internet usage cannot be ruled out as is evident from the variance decomposition analysis therefore this study recommends that in addition to boosting the existing measures for combating co2 emissions oecd countries need to use ict equipment not to simply reduce its own carbon footprint but also to exploit ict enabled emissions abatement potential to reduce emissions in other sectors such as the power energy agricultural transport and service sectors

assessing the role of institutions in limiting the environmental externalities of economic growth emissions of pollutants tend to be procyclical as they generally increase with economic growth however as government policy has a role to play in the mitigation of the environmental consequences of economic activity the quality of institutions may influence the procyclicality of pollution and reduce the environmental cost of economic growth based on the assumption that changes in emissions are stronger at earlier stages of development we develop a non linear framework and confirm first the presence of income related threshold effects in the relationship between pollution co 2 and greenhouse gas emissions and growth for a panel of 142 countries over a period spanning from 1960 to 2017 we also find that institutional quality influences this relationship as the quality of institutions lowers the value of the threshold and the degree of procyclicality of emissions these results bring therefore evidence that higher institutional quality can attenuate the environmental externalities of economic growth
