central bank constitutions for federal monetary unions abstract in a monetary union the central bank constitution must distribute the power over monetary policy between the members and the administrative center of the union we compare alternative distributions and evaluate their performance dominance of regional interests always leads to inefficient monetary stabilization policies whether or not dominance of regional interests leads to a higher long run rate of inflation depends on the union s political constitution

inflation and relative price variability in the euro area evidence from a panel threshold model the impact of inflation on relative price variability rpv generates an important channel for real effects of inflation this article provides first evidence on the empirical relation between inflation and rpv in the euro area stirred by the widespread use of inflation caps or target bands in monetary policy practice we are particularly interested in threshold effects of inflation in line with the predictions of monetary search models our results indicate that expected inflation significantly increases rpv only if inflation is either very low below 0 95 per annum p a or very high above 4 96 p a

testing an alternative habit persistence model marshall long ago noted the phenomenon of past consumption being highly correlated with current consumption if habit was indeed a major determinant of current consumption behavior then the neoclassical theory of utility maximization should take it into account a rigorous incorporation of habit formation into consumer theory began with gorman 12 pollak 21 22 23 laid out the theoretical conditions that needed to be satisfied in order for habit persistence to be consistent with the utility maximizing model of consumer behavior competent empirical work in this area was done initially by houthakker and taylor 14 with subsequent studies by manser 16 phlips 18 19 pollak and wales 24 anderson and blundell 2 and blanciforti and green 8 these papers have focused on examining the impact of measured past consumption on current consumption blundell 9 provides a comprehensive review of this literature

estimating theoretically consistent demand systems using cointegration techniques with application to greek food data abstract the use of time series techniques cointegration and error correction models has been offered as a potentially promising way in estimating demand systems that resolve the perennial issue of violating the theoretical postulates of homogeneity and symmetry the empirical results of this paper based on linearized aids and greek food data indicate that sample size aggregation schemes and model specification seem to be important factors in the estimation of a theoretically consistent demand system they also show that homogeneity is sensitive to sample size while symmetry is sensitive to the aggregation scheme adopted

the determination of foreign banking location abstract in this paper we examine the determinants of foreign bank location we initially present some time series data on the postwar expansion of international banking we show that foreign branching increased very rapidly from about 1960 to the mid 1980s and slowed significantly after 1985 one interpretation of this growth in foreign branching is that it largely paralleled the increase in trade and foreign direct investment although it may also have been encouraged by the improvements in communications and the rapid financial innovation of the 1960s and 1970s to assess the role of trade and foreign direct investment on bank expansion we employ a cross sectional analysis of the pattern of foreign bank offices whereas previous studies have focused on a single parent or host country our study extends the existing literature by analyzing the location of nearly 2000 overseas offices across 37 patent and 82 host countries our results suggest a significant relationship between the pattern of bank location trade and foreign direct investment we define a banking centre as one in which there are more foreign banks than can be explained in terms of real business activity and we show that the usa uk switzerland singapore and indonesia most clearly qualify as banking centres we also provide some evidence for a sample of host countries that the abnormal number of bank offices is related to capital market activities

weak separability and the estimation of elasticities in multistage demand systems the necessary conditions for multistage budgeting to be at least approximately justified are reviewed and the plausibility of these assumptions i e weak separability and low variability of price indices with utility level are discussed using no further assumptions simple relationships between expenditure and price elasticities in different budgeting levels are derived these results are applied to a three stage model for swedish food consumption and it is shown that the assumptions are not inappropriate restricting the analysis to the last stage of a multistage budgeting process is also shown to lead to considerable errors which could well have policy consequences

the mix of international banks foreign claims determinants and implications we analyze the cross country determinants and financial stability implications of the mix of international banks foreign claims we distinguish between local claims extended by host country affiliates and cross border claims booked outside the receiving country using data on italian spanish and us banks foreign claims we find that the share of local claims is driven by restrictions on banking sector openness and by local scale economies business opportunities the impact of limits on property rights entry requirements start up and informational costs is less robust finally foreign claim volatility is lower in countries with a larger share of local claims

drivers of cross border banking exposures during the crisis abstract the recent crisis highlighted the role of cross border banking linkages this paper analyzes these linkages through an examination of both banking systems foreign credit exposures and borrower countries reliance on foreign bank credit it does this by combining bis data with bank level data the results indicate that the proposed refinements on measuring those two exposures are important especially when foreign bank affiliates funding relies heavily on local deposits after developing novel and necessary break in series and exchange rate variation adjustments estimations looking at the driving factors of both measures during 2006 2012 highlight i the role of systemic banking crises and global financial conditions in the evolution of banks foreign credit exposures ii the role of a larger set of factors in the case of the evolution of borrower countries reliance on foreign bank credit how countries borrowed from whom they borrowed and global financial and domestic demand conditions

money and the dispersion of relative prices a price dispersion equation is tested with data from the german hyperinflation the equation is derived from a version of lucas s and barro s partial information localized market models in this extension different excess demand elasticities across commodities imply a testable dispersion equation in which the explanatory variable is the magnitude of the unperceived money growth in order to test this hypothesis a price dispersion series is constructed and a measure of the unperceived part of money growth is estimated the model receives support from the empirical analysis although it is evident that unincluded variables have important effects on price dispersion

distance constraints the limits of foreign lending in poor economies how far does mobility of multinational banks solve problems of financial development using a panel of 80 000 loans over 7 years i show that greater cultural and geographical distance between a foreign bank s headquarters and local branches leads it to further avoid lending to informationally difficult yet fundamentally sound firms requiring relational contracting greater distance also makes them less likely to bilaterally renegotiate and less successful at recovering defaults differences in bank size legal institutions risk preferences or unobserved borrower heterogeneity cannot explain these results these distance constraints can be large enough to permanently exclude certain sectors of the economy from financing by foreign banks

a test of the habit formation hypothesis using household data numerous studies have confirmed the importance of habit formation as represented by a lagged dependent variable in demand analysis although all work to date has been based on aggregate time series data this study uses household level bls interview panel data to test the habit hypothesis an interrelated demand system for seventeen goods is estimated from cross section data and compared with a similar system based on time series data the results show that the habit component is significantly different between the two data sets and much smaller in the cross section data habit effects while not as large in cross section data as time series are still highly significant several explanations are offered concerning why the two sets of estimates differ copyright 1991 by mit press

inflation price dispersion and market structure abstract in this paper we use a novel data set containing prices from bazaars convenience stores and supermarkets in istanbul to re examine the relationship between price dispersion and inflation although existing evidence is mixed we find positive and significant relationships between dispersion on the one hand and lagged dispersion and unexpected product specific inflation on the other we also find evidence that dispersion is initially decreasing in anticipated aggregate inflation but is eventually increasing finally average price duration and dispersion are lowest in the bazaar this is intuitive since menu and search costs should be minimal in that market structure

policy effectiveness in an open multi market economy with risk neutral exchange rate speculation abstract in an open multi market equilibrium model of the business cycle the informational role of a forward exchange market is that the forward rate aggregates individual perceptions of the aggregate state of the economy in the case of risk neutral exchange rate speculation the forward rate perfectly reveals average expectations of current nominal shocks that hit the economy this paper analyzes the informational implications of forward speculation when markets are structurally diverse the two types of structural diversity considered are heterogeneous price elasticities of output demand and supply and asymmetric information between traders in output markets and traders in asset markets in contrast to previous results the paper shows that risk neutral speculation is not in general sufficient to generate a fully revealing rational expectations equilibrium in which monetary policy is ineffective

the relationship between relative prices and the general price level it is very nearly a truismi amaong neoclassical economists that the public is wont to confuse changes in the general price level with relative price changes correspondingl y one might speak of the independence between the two as one of the central postulates of the neoclassical tradition william stanley jevons was aml ong the first to identify this basic dichotomin economic life as well as to attempt to explain the ordinary citizen s seenming incapacity to understand it

monetary policy and inflation uncertainty in the united states and germany friedman s 16 proposition that increased inflation uncertainty may adversely affect real economic variables has received much attention over the last decade the theoretical arguments for such real effects are compelling however the empirical evidence on their presence and magnitude in different countries is mixed most results for the postwar u s economy strongly support the proposition 28 25 26 19 24 7 whereas it is generally rejected for the german economy 23 17 8 2 while a direct comparison of the u s and german results is difficult due to a lack of uniform sample periods data definitions estimation techniques and or measures of inflation uncertainty the evidence to date nevertheless suggests that the role of inflation uncertainty differs sharply between the two countries the question then arises what factor s can explain the difference one popular explanation is that the monetary authorities in the united states and germany respond quite differently to accelerating inflation 3 so that the behavior of uncertainty differs across countries 4 the u s federal reserve is often criticized for switching frequently between the primary policy goals of price stability and full employment possibly due to political pressures 21 30 since inflation is primarily a monetary phenomenon in the long run it is likely that such stop and go policies increase the uncertainty about future steady state inflation which in turn can adversely affect real output growth by reducing overall economic efficiency the german bundesbank on the other hand is reputed for its staunch and credible commitment to price stability which often takes precedence over other policy goals a more consistent and predictable

the information content of the exchange rate and the stability of real output under alternative exchange rate regimes abstract when the exchange rate is flexible and thus responds to market forces it provides agents with useful information while when it is fixed by a feedback rule it does not the implications of this asymmetry for the stability of real output under the two regimes is discussed it is shown that whenever shocks are predominantly of one variety or when domestic monetary shocks accompanied by one real shock a flexible exchange rate does a better job of stabilizing real output than does a fixed exchange rate these results undermine arguments favoring fixed exchange rates because they discipline monetary policy in addition it is demonstrated that managed floating rules and exchange rate feedback rules are irrelevant for the distribution of real output

a cointegrated vecm demand system for meat in italy this article applies cointegration techniques to estimate a monthly demand system for meat in italy in contrast to existing studies where engle and granger s two step procedure and triangular vector error correction model tvecm representations are usually exploited it applies a cointegrated vector error correction model vecm where also prices and expenditure enter endogenously the system and the cointegration rank is not assumed to be known a priori but subject to inference it highlights some of the advantages of using the vecm compared to the tvecm including the possibility of testing the cointegration rank of the system and the weak and strong exogeneity of prices and expenditure within a well specified statistical model this may lead to remarkable improvements in the efficiency of parameters system estimates

cost sharing versus block funding in a federal system a demand systems approach this paper employs a maximizing framework consistent with the axioms of consumer preference to analyze local government s choice of spending on different social services within this framework it is possible to include both block funding and cost sharing intergovernment transfer schemes canada s movement to block funding from the cost sharing method of financing provincial expenditures on hospitals medical care and post secondary education is analyzed the results indicate that the provincial governments actions are generally consistent with a significant maximizing model of consumer behavior and that the change to block funding had a significant impact on real provincial funding of some previously cost shared social services

a semi nonparametric approach to the demand for uk monetary assets we estimate an asymptotically ideal model of the demand for uk personal sector monetary assets we use data that are consistent with utility maximizing behaviour and find that uk monetary assets are generally substitutes in use the estimated elasticities of substitution during the 1980s and the early 1990s indicate that a relatively broad monetary aggregate should be used in economic studies the results also suggest that any policy based on interest or user cost elasticities of substitution between financial assets should be based on the morishima elasticities as the allen uzawa calculation can give misleading results

dynamic factor demand equations in u s and canadian agriculture abstract this research provides one of the first empirical estimates of a data based dynamic factor demand model for american and canadian agriculture models such as these deserve more widespread use in the empirical analysis of agriculture these models have the advantage that they do not impose inappropriate dynamics on the data rather they permit the data to select the appropriate dynamics we use a model originally developed by anderson and blundell this model is a general first order dynamic model which contains as testable hypothesis several simpler models this model permits us to estimate the long run agricultural production structure as a subset of the dynamic parameter estimates we will test this long run structure for symmetry homotheticity and neutral technical change the estimated models may be used to test for three alternative dynamic structures in the limit dynamics may not be needed and we can test for the static long run equilibrium model two intermediate cases are the autoregressive and the partial adjustment models which are simpler than the general model but still include dynamics our results suggest that the long run equilibrium model is unsatisfactory in both countries a dynamic model is needed in both countries the two more restricted dynamic models are rejected the general dynamic model is required in canada the long run equilibrium structure is homothetic with neutral technical change in the united states homotheticity is also accepted but neutral technical change is rejected

the impact of liberalization and foreign investment in colombia s financial sector abstract this study analyzes financial liberalization measures undertaken in 1990 of which an opening to foreign investment was a major component after a brief description of the major changes in legislation on foreign investment we compare performance of foreign owned vs domestic banks first using a descriptive approach then in a more systematic manner using econometric analysis panel data estimations reveal that financial liberalization in general had a beneficial impact on bank behavior in colombia by increasing competition lowering intermediation costs and improving loan quality although the positive contribution of foreign entry may be overstated in recent studies by not controlling for other liberalization factors foreign and domestic entry beginning in 1990 did improve bank behavior by enhancing operative efficiency and competition however the greater competition may have resulted in increased risk and a subsequent deterioration in loan quality particularly among domestic banks

information or regulation what drives the international activities of commercial banks information costs and regulatory barriers distinguish international financial markets from national ones using panel data on bilateral assets and liabilities of commercial banks i empirically determine the impact of information costs and regulations and i isolate intra eu financial linkages i confirm that information costs and regulations are important factors influencing international asset choices of banks but their relative importance differs among countries

the implications of tourism specialisation in the long run an econometric analysis for 13 oecd economies abstract the paper aims to illumine the longrun impact of specialisation in tourism it is shown that specialisation in tourism may not be deleterious for economic welfare once the terms of trade are considered conditions for an improvement in welfare are laid out and their existence tested by econometric methods within an almost ideal demand system formulation of tourist expenditure for 13 oecd economies the analysis uses cointegration techniques and novel sequential break dating procedures evaluated where the time dimension is small the values of the estimated parameters suggest that long run growth may not be harmed by tourism specialisation

an investigation into the demand for alcoholic beverages in canada a choice between the almost ideal and the rotterdam models in this article i investigate the historical pattern of interactions in the demand for three categories of alcoholic beverages in canada using both the differential almost ideal and the differential rotterdam demand systems i evaluate these models based on several decision criteria including model encompassment based on the j test structural stability conformity with demand theory and the credibility of the estimated price and income responses in an attempt to determine which of these models is better suited for explaining the demand for alcoholic beverages the results reveal that both models satisfy the restrictions of demand theory and of structural stability but the rotterdam model is preferable on grounds of the remaining two criteria

bank lending to small businesses in latin america does bank origin matter recently foreign bank participation has increased significantly in developing countries fueling concerns that foreign banks might extend credit only to certain sectors leaving customers like small businesses unattended using bank level data for four latin american countries during the mid 1990s we investigate whether bank origin affects the share and growth of lending to small businesses while on average foreign banks seem to lend less to small businesses regression results reveal significant differences between small and large foreign banks in general we find that the latter surpass large domestic banks in their share and growth of lending to small businesses

habit formation and demand for sugar sweetened beverages using scanner data we estimated demand for nine nonalcoholic beverages under habit formation we found strong evidence for habit formation although demand for sugar sweetened beverages by low income households is less elastic to own price changes compared with high income households there is evidence that high income households consider beverages to be more substitutable than low income households do a half cent per ounce tax on store purchased sugar sweetened beverages will result in a moderate reduction in consumption of sugar sweetened beverages for both income strata because of habit formation long run national tax revenue from a sugar sweetened beverage tax is about 15 to 20 lower than short run revenue

interrelated factor demands from dynamic cost functions an application to the non energy business sector of the uk economy in this paper we propose a dynamic cost function which allows us consistently to derive a set of dynamic interrelated factor demand equations in the general error correction form introduced by anderson and blundell 1982 this paper expands results recently published in urga 1996 it shows that the derivation of an effective underlying cost function allows us to identify the full set of parameters of the underlying process this does not happen in the standard anderson blundell formulation we report an empirical exercise used to model the so called supply side of the london busines school large scale economic model where we estimate both the set of factor demands and the underlying dynamic cost function for the non energy business sector of the uk economy

empirical modelling of the aggregation error in the representative consumer model this paper examines different approaches to modelling the aggregation error associated with the representative consumer model each approach is based on an analytical framework intended for modelling aggregate time series data on quantities and prices with potential additional measures of income distribution simple functions that track aggregation error over time are found to perform better than more complex and theoretically sophisticated models an explanation is given based on typical time series characteristics of economic data

foreign banks and credit stability in central and eastern europe a panel data analysis abstract we examine whether foreign and domestic banks in central and eastern europe react differently to business cycles and banking crises our panel dataset comprises data of more than 250 banks for the period 1993 2000 with information on bank ownership and mode of entry during crisis periods domestic banks contracted their credit base whereas greenfield foreign banks did not also home country conditions matter for foreign bank growth as there is a significant negative relationship between home country economic growth and host country credit by greenfields finally greenfield foreign banks credit growth is influenced by the health of the parent bank

voluntary export restraints and rationing u k leather footwear imports from eastern europe following the imposition of a quantitative import restriction someone somewhere must be quantity rationed concentrating on demand we develop methods to test and allow for the presence of rationing in the estimation of demand equations and in the calculation of the welfare effects of quantitative restrictions using a ces model we analyse the voluntary export restraints on u k imports of two types of leather footwear from comecon countries the results suggest that even if prices did not rise to clear the market u k consumers could have lost up to 60 million in 1986 from these restrictions

an intertemporal system of dynamic consumer demand functions abstract this paper constructs and estimates a system of dynamic consumer demand equations under the assumption of rational expectations about anticipated human wealth the traditional one period budget constraint is replaced by the lifetime anticipated wealth constraint lagged dependent variables are rationalized by an adjustment cost argument in the model presented both the dynamic adjustment coefficients as well as the parameters characterizing the underlying long run preferences are identified and can be estimated we find that a weak version of the reh cannot be rejected on the data in common with most empirical studies on demand behaviour we have to reject the symmetry restrictions

the demand for cigarettes in japan a two stage budgeting procedure was used to estimate demand elasticities for cigarettes in japan cigarettes were disaggregated into japanese u s and rest of world testing for habit effects was performed at both stages results indicated that habit effects occur for total expenditures on cigarettes but not between types

expenditure allocation across nondurables services durables and savings an empirical study of separability in the long run the separability of categories of consumption expenditures and savings are empirically examined in the context of an error correction model of aggregate quarterly expenditure allocations in canada some evidence is found for separability of consumption allocations from savings in both the long run structure and short run dynamics of the model lending some support to the use of the assumption in modelling consumption behaviour

testing dynamic specification for import demand models the case of cotton error correction models impose few prior restrictions on dynamic model specification and allow the data to determine model structure despite this obvious advantage few applications have adopted the error correction model to explain trade flows an error correction model of cotton import demand is estimated for france japan and hongkong a variety of tests are applied to determine the dynamic structure of the model it is found that the most general models are those that best fit the data for cotton import demand long run elasticities from these general models are significantly different than elasticities derived from a comparable static model

how foreign participation and market concentration impact bank spreads evidence from latin america increasing foreign participation and high concentration levels characterize the recent evolution of banking sectors market structures in developing countries the authors analyze the impact of these factors on latin american bank spreads during the late 1990s their results suggest that foreign banks were able to charge lower spreads relative to domestic banks this was more so for de novo foreign banks than for those that entered through acquisitions the overall level of foreign bank participation seemed to influence spreads indirectly primarily through its effect on administrative costs bank concentration was positively and directly related to both higher spreads and costs

price premium for high efficiency refrigerators and calculation of price elasticities for close substitutes a methodology using hedonic pricing and demand systems this article uses the hedonic pricing method to estimate the price premium paid for the highest energy efficiency label a in the refrigerators market of the basque autonomous community spain the estimated figure is 8 9 of the final price or about 60 euro which represents one third of the energy savings that a consumer gets during the lifetime of a refrigerator with the highest energy efficiency label this figure is then combined with the linear version of the almost ideal demand system la aids to obtain own and cross price elasticities of demand the information presented here is useful for policy design and analysis the results indicate that the demand for refrigerators with the highest energy efficiency label is highly sensitive to price variations

simple tests of distributional effects on macroeconomic equations the presence of distributional effects in macroeconomic equations is shown to coincide with nonlinearity in micro behavioral relationships parameters estimated with aggregate data as in representative agent models contain distributional biases that are not measurable using aggregate data alone tests for distributional effects and other measures of the extent of aggregation problems are derived using distributional data observed over time significant distributional effects are noted for a model of annual aggregate u s commodity expenditure data a static model that accommodates individual heterogeneity is found to be statistically equivalent to a simply dynamic model that accommodates first order autocorrelation

consumer behaviour in greece an application of the almost ideal demand system this paper estimates the almost ideal demand system on greek data for the period 1960 1986 for seven commodity groups the results conform with earlier research findings that the homogeneity and symmetry restrictions of demand theory are broadly inconsistent with the data the imposition of the restrictions leads to substantial changes in the estimated elasticities in both the static and dynamic specifications the introduction of habit effects with lagged consumption supported statistically by the data led to plausible results leaving however the problem of rejection of homogeneity and symmetry intact

an inverse demand analysis with introduction of quality effects an application to spanish consumption of fruit and vegetables this article analyzes consumer preference for fruit and vegetables when by using time series with socioeconomic characteristics of households there can be seemingly unobserved quality effects which are increased by aggregation the changes in spanish demand for fresh and processed fruit and vegetables over the period 1987 2000 are discussed following previous tests and analyses quantities are taken as predetermined and prices as matching the offer conditions thus quality effects based on the nutritional and or health value of the product are estimated from the error terms associated with the functions of the unit values quality variables are introduced as taste shifters in the inverse demand system laitinen theil model the results show the positive effects of quality differences on the normalized price for the group of products through own quality flexibilities and the negative effects between fresh and processed products through cross quality flexibilities

a flexible dynamic model of multiproduct technology for the west german economy this paper tests symmetry and negativity of the slutsky matrix for a system of demand functions derived from an aggregate model of multi product technology within a flexible dynamic framework the model considers three inputs and three outputs including imports and exports of intermediate goods we derive a static demand model from a trans log cost function and specify the data generation process by a stationary arx 1 1 model results based on west german quarterly data indicate that the integrability conditions are not rejected when imposed on the arx 1 1 model whereas they are rejected for all the less general dynamic models considered

conditional relative price variance and its determinants open economy evidence from germany the authors present empirical tests of two hypothesis derived from an open economy version of the multimarket equilibrium model the first hypothesis holds that the conditional relative price variance is positively related to the variance of domestic monetary and foreign nominal and real shocks the second hypothesis claims a negative impact of an increase in conditional relative price variance on normal output in contrast to earlier studies the authors use direct measures of conditional relative price variance based on arch estimates the authors results show that both hypotheses are consistent with german data copyright 1991 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

spanish food demand a dynamic approach other empirical works have demonstrated that spanish food demand seems to have a dynamic structure however the commonly used dynamization processes are too restrictive to explain the dynamic food consumers behaviour a more general model that is able to incorporate different dynamic structures partial adjustment first autoregressive and static and allows for direct estimation of long run coefficients has been used this general framework is applied to the generalized addilog demand system gads for annual spanish data covering 1964 to 1991 results indicate that an autoregressive gads fits well the data satisfying the theoretic restrictions finally the expenditure and price elasticities are calculated

relative price variability evidence from supply and demand events abstract previous studies of relative price variability assume that all supply changes are unanticipated or that supply elasticities are equal across markets in this paper we extend these models by relaxing these restrictive assumptions our resulting theoretical expression for relative price dispersion reveals an independent role for unanticipated and anticipated supply events subjecting our model to empirical testing we find that this dichotomy of supply shocks is not rejected by the data for the period 1970 1981

advertising in demand systems testing a galbraithian hypothesis in this paper we argue that the influence of advertising upon the inter product distribution of demand is a system wide phenomenon which is investigated better through a demand equation system rather than through single equation methods attention is focused upon a dynamic version of deaton muellbauer s aids model modified to include advertising terms within this framework using data on consumer s non durable expenditure in the uk we carry out a preliminary test of galbraith hypothesis that advertising may affect the composition of aggregate consumer demand

interest rates aggregate information and monetary policy abstract interest rates set on economy wide markets represent an important source of information to economic agents within the class of business cycle models advanced by lucas and barro this paper explores the information conveyed by such aggregate signals and the types of monetary policies that can influence economic activity by changing the information content of interest rates

foreign banks trends and impact over the past two decades foreign banks have become much more important in domestic financial intermediation heightening the need to understand their behavior we introduce a new comprehensive database made publicly available on bank ownership including the home country of foreign banks for 5 324 banks in 137 countries over the period 1995 2009 we document large increases in foreign bank presence in many countries but with substantial heterogeneity in terms of host and banks home countries bilateral investment patterns and bank characteristics in terms of impact we document that the relation between private credit and foreign bank presence importantly depends on host country and banks characteristics specifically foreign banks only seem to have a negative impact on credit in low income countries in countries where they have a limited market share where enforcing contracts is costly and where credit information is limited available and when they come from distant home countries this shows that accounting for heterogeneity including bilateral ownership is crucial to better understand the implications of foreign bank ownership

banking across borders abstract the international linkages between banks play a crucial role in today s global economy existing models explain these links largely on the basis of portfolio theory in which banks diversify lending these models have found limited empirical support and do not speak to several relevant dimensions of the data they do not explain heterogeneity in the degree to which banks operate through foreign affiliates fund their activities abroad or matter for local lending in foreign countries this paper proposes a complementary theory of banking across borders that is based on elements of international trade theory in the model banking across borders arises because countries differ in their relative factor endowments and in the efficiency of their banking sectors based on these differences the pattern of foreign bank asset and liability holdings emerges endogenously this parsimonious model provides a rationale for the observed heterogeneity in foreign bank activities and is consistent with key patterns in the data

errata aggregation distribution and dynamics in the linear and quadratic expenditure systems using canadian data 1965 86 the author confirms and extends thomas m stoker s 1986 results on the rule of distributional effects in demand systems the confirmation consists of evidence from the linear expenditure system model showing that distributional effects are statistically significant and can displace ar 1 dynamics in the disturbances the extension is made to the quadratic expenditure system model and an argument is advanced that standard habit formation dynamics may reflect omitted distributional effects the evidence supports this conjecture this suggests that the author may have been drawing the wrong conclusions from expenditure studies rather than inferring dynamic behavior he should have been concluding that these models are misspecified copyright 1992 by mit press

the logic of testing structural change in meat demand a methodological analysis and appraisal in the past two decades the profession has expended valuable resources testing structural change in meat demand with mixed results overlooked to date is a fundamental methodological problem that transcends all methods of testing for structural change in this study a methodological framework is used to show that there is no valid test of structural change because of this result additional criteria from the methodology literature are used to evaluate the literature on structural change in meat demand and to provide suggestions for fertile areas of future research

a note on the location choice of multinational banks the case of japanese financial institutions abstract there are many studies investigating the location choice of foreign direct investment fdi of us banks nigh et al journal of international business studies 17 1986 59 72 find that the choice does not depend on local banking opportunity this paper examines what factors affect the location choice of japanese multinational financial institutions our results are consistent with previous studies analyzing us banks in that the fdi of the manufacturing industry is an important determinant of the location choice of japanese financial institutions however our results differ from nigh et al in that japanese financial institutions choose their locations at least partially based on the local banking opportunity in the host countries

forecasting with the almost ideal demand system evidence from some alternative dynamic specifications the almost ideal demand system is used as a representation of long run demands in discrete time and continuous time error correction models to produce forecasts of budget shares beyond the sample period the estimated models are subjected to a battery of tests and an analysis of the forecasts indicates that continuous time adjustment mechanisms based around fully modified estimates of the long run preference parameters provide a remarkably accurate method of forecasting budget shares

an analysis of the disaggregated manufacturing exports of the asian nies to eec usa and japan this paper examines the export performance of the four asian newly industrialized economics nies by modelling their bilateral export flows to three main oecd blocks the usa japan and the european community our estimated export demand models reveal interesting asymmetries between these three areas of destination which do not emerge from previous aggregate empirical studies of nie export performance

habit seasonality and time aggregation in consumer behaviour habitual behaviour in consumer demand analysis is generally portrayed via some form of a lagged dependent variable model the purpose of this paper is to explore the implications for habit behaviour of time aggregation this is done by specifying both habit and seasonal components in demand relations the results indicate that much of what has traditionally been identified as habitual behaviour is in fact seasonal effects

global deleveraging and foreign banks lending to latin american countries proquest denotes formulae omitted lending by foreign banks to emerging markets is a defining feature of finan cial globalization in the years preceding the recent global crisis foreign bank lending to emerging economies expanded rapidly whether directly from parent banks headquarters in advanced economies cross border flows or through their affiliates operating in host countries in the case of latin america lending by foreign banks became a significant source of funding for households and firms over the last decade although there is no consensus on the benefits of foreign banks activity on balance the presence of foreign owned banks is generally believed to have enhanced competition and aided overall financial stability 1after the onset of the global credit crunch in 2008 09 however foreign banks became a potential conduit through which financial stress in advanced economies could spread to emerging markets funding shortages in interbank markets and the need to deleverage bank balance sheets raised concerns that for eign banks would pull back from international lending activities potentially dis rupting macroeconomic and financial stability in emerging market economies 2in latin america the growth rate of total foreign banks credit slowed sig nificantly after the collapse of lehman brothers in the third quarter of 2008 yet crucially the lending behavior of parent banks vis a vis their local affili ates in latin american economies was starkly different cross border lend ing which is mostly denominated in foreign currencies followed a boom bust pattern reversing sharply after the fourth quarter of 2008 in contrast lending by their affiliates operating locally a large share of which is denominated in host countries domestic currencies proved much more resilient and contin ued to expand even amid the financial turmoil this paper explores how the global financial shocks were transmitted to latin american countries through the foreign bank lending channel for this purpose we undertake an econometric analysis of the determinants of foreign banks lending to latin american and caribbean countries using data from the bank for international settlements bis the sample covers twelve latin american countries and spans 1999 the first year for which data are available on a quarterly basis to the first quarter of 2009 at the height of the global credit crunch we assess the effects of three factors that characterized the recent global financial turmoil the freezing of international money markets the deterioration of the financial health of parent banks in advanced economies and more restrictive lending standards in developed countries banking sys tems the sample period used in the paper thus provides an event study of the transmission of the global crisis to foreign banks lending rather than a systematic description of foreign banks reaction to crises to identify the channels of transmission and the possible mitigating fac tors we exploit differences in the geographic structure cross border versus local affiliates and currency mix foreign versus domestic of foreign banks lending to latin american countries at the bilateral level that is between each latin american recipient country and a bis reporting creditor country in a given quarter for this purpose we rely on publicly available data from the bis on the currency structure of foreign banks claims together with confidential bis data on the share of foreign banks total lending extended through local affiliates in both domestic and foreign currencies our results indicate that international money market conditions had a sig nificant impact on foreign banks lending to latin american and caribbean countries in particular an increase in the ted spread caused by liquidity shortages in the global interbank market adversely affects foreign banks lending growth to latin american countries

a monthly dynamic consumer expenditure system for germany with different kinds of households a dynamic monthly consumer expenditure system is estimated for an aggregate household and three household types using recent german data the results tend to support the long run restrictions of homogeneity and symmetry for the aggregate household but only when short run dynamics are modelled following the method of anderson and blundell the required lags are short however the results for the partiallydisaggregated data are markedly different in particular the integrability restrictions can be rejected for the sample of high income workers therefore contrary to the usual presumption the less aggregated data seem more at variance with the restrictions of utility maximization

testing restrictions in a flexible dynamic demand system an application to consumers expenditure in canada traditionally restrictions on systems of demand equations have been tested using static models whilst being estimated with time series data this paper develops a vector time series model of expenditure shares in the context of a singular dynamic demand system the model allows for non symmetric and non homogeneous short run behaviour the homogeneity and symmetry restrictions are only examined in the long run structure results based on canadian time series data are presented and reject the current practise of static modelling while restrictions suggested by economic theory are not rejected when imposed on the long run structure

non stationarity and the import demand for virgin olive oil in the european union the aim of this study is to analyse the importation of virgin olive oil to european union countries paying special attention to the spanish export contribution the method used is based on the estimation of an imports demand system the novelty of the paper lies not in the modelling approach but in the explicit consideration of the univariate characteristics of series that is included in the analysis since prices are non stationary cointegration among them has been tested results indicate that they are cointegrated and that homogeneity holds as a result relative prices are included in the imports demand system structural change is also considered so as to account for the entrance of both spain and greece into the eu during the period studied results demonstrate the leadership of spain within the eu virgin olive oil market as well as the increasing competitiveness of greek oil

the extension of international credit by us banks a disaggregated analysis 1988 1994 abstract we use simultaneous equation estimation techniques to analyze decisions made by 35 us banks with respect to credit extended domestically and to credit extended within 16 foreign countries 1988 1994 our results indicate that foreign credit extension by us banks follows the commercial expansion of us businesses abroad and is greater in countries with expanding economies they are inconsistent with the notion that banks trade off credit activities undertaken domestically and abroad

age trend and cohort effects in a macro model of canadian expenditure patterns a quadratic almost ideal demand system allowing for age cohort and trend effects is developed at the macro level the model is estimated by maximum likelihood using a three tier iterative search method applied to pooled 1961 1992 time series for five regions of canada and six categories of expenditure hypothesis tests indicate support for the model specification elasticities are compared with those reported in other studies with special attention to food effects of demographic and trend variables on elasticities and expenditure shares are investigated an overall conclusion is that such effects can be very important in a macro demand system

regulations market structure institutions and the cost of financial intermediation this paper examines the impact of bank regulations market structure and national institutions on bank net interest margins and overhead costs using data on over 1400 banks across 72 countries while controlling for bankspecific characteristics the data indicate that tighter regulations on bank entry and bank activities boost the cost of financial intermediation inflation also exerts a robust positive impact on bank margins and overhead costs while concentration is positively associated with net interest margins this relationship breaksdownwhencontrolling for regulatory impediments to competition and inflation furthermore bank regulations become insignificant when controlling for national indicators of economic freedom or property rights protection while these institutional indicators robustly explain cross bank net interest margins and overhead expenditures thus bank regulations cannot be viewed in isolation they reflect broad national approaches to private property and competition

dynamic translog and linear logit models a factor demand analysis of interfuel substitution in us industrial energy demand abstract we compare and contrast two popular dynamic flexible functional forms for cost functions the translog and the logit j bus econ stat 8 1990 347 353 using data on us industrial energy demand from 1960 to 1992 which has been analysed by previous studies energy econ 11 1989 89 94 appl econ 21 1989 931 945 j bus econ stat 13 1995 459 465 we show the crucial role played by different dynamic formulations of the translog in this analysis of factor demands with respect to rates of dynamic adjustment and substitution possibilities we conclude that the poor performance of the dynamic translog relative to the dynamic logit cannot be explained solely by dynamic model mis specification or the inclusion of price unresponsive non energy fuel use data our most robust empirical result is that coal and oil are substitutes

identification of habit in japanese food consumption abstract demand models were estimated for five commodities using annual retail level japanese data estimates were made with the houthakker taylor houthakker h s taylor l d 1970 consumer demand in the united states analysis and projections harvard university press new york ma state adjustment model significant lags were found for meat and cereal which means that habit is important for these commodities some habit affects were also found for seafood

price and income elasticities of demand for passenger transport fuels in spain implications for public policies abstract the significant increase in passenger transport activity cars experienced by spain and its associated increase in energy consumption have several associated negative aspects including a greater dependence on foreign energy sources and higher ghg emissions therefore reducing the level of transport activity would bring important socioeconomic and environmental benefits the aim of this paper which focuses on energy consumption in the passenger transport is fourfold 1 to provide a diagnostic of energy consumption in the spanish passenger transport system and the related problems 2 to develop a model to calculate price and income elasticities of demand for transport fuel 3 to apply this model to the spanish passenger transport sector 4 to infer policy recommendations derived from the results of the diagnostic and the model it is claimed that in view of those low price elasticities and high income elasticities and if a reduction in the scale of transport activity is deemed socially desirable a combination of instruments is necessary fuel taxes play an important role within this combination apart from their long term effects the low price elasticity of demand for transport fuel would allow the collection of a significant amount of revenues which could eventually be earmarked to encourage reductions in private transport demand and modal shifts with other instruments

the demand for food and beverages in norway abstract the demand for food and beverages is estimated within a three stage demand model the separability structure of the model is checked by nonparametric tests some generalized axiom of revealed preference garp violations are detected in one of the subsystems however they are removed by small adjustments in the quantities of fish and the violations are interpreted as results of measurement errors the almost ideal demand system is used in the static and a dynamic version the results of various specification and misspecification tests suggest that the static version performs poorly as compared with the dynamic version norwegian demand elasticities for disaggregate food commodities have rarely been estimated within a system framework so the results are of intrinsic interest the elasticities estimated by using the dynamic model are of the expected signs and reasonable magnitudes the values are stable over time for most commodities elasticities estimated within a subsystem are conditional on the goods included in that system and they may differ from the more policy relevant unconditional elasticities estimated within a system including all goods adjustment formulas are used to approximate the unconditional elasticities from the estimated conditional elasticities there are considerable differences between the numerical values of the conditional and unconditional elasticities for several of the foods the unconditional own price elasticities are in the interval 0 20 to 0 89 the own price elasticities for hot drinks and for milk are most inelastic the unconditional expenditure elasticities for food away from home fish soft drinks and alcoholic beverages are above one while the expenditure elasticity for hot drinks is about zero

interrelated factor demands for manufacturing a dynamic translog cost function approach abstract in this paper we report the results of estimating a joint model for labour capital and energy using the transcendental logarithmic cost function of christensen jorgenson and lau 1973 this allows us to determine both the own price and cross elasticities of substitution between labour capital and energy we combine a model of factor shares with a dynamic adjustment process for each factor we also impose on the cross equation restrictions necessary to provide additivity homogeneity and symmetry since the covariance matrix in systems of share relationships is singular we follow the suggestions of anderson and blundell 1982 and employ a mullivariate error corrrection model the results suggest that additivity symmetry and homogeneity restrictions do hold and that there are short run increasing returns to scale

the changing structure of local credit markets are small businesses special abstract in many countries consolidation in the banking industry has reduced the number of small banks and led to significant shifts in market shares deregulation has fostered entry in local credit markets and the expansion of branch networks increasing competition in local markets small businesses are believed to be more vulnerable to these changes since they are more dependent on credit from local banks in this paper we investigate the consequences of consolidation and entry for these borrowers compared with those for large firms we employ a data set for italy which provides information on volumes of loans and bad loans by size of borrower with a detailed geographical partition we find that mergers are followed by a temporary reduction in outstanding credit to all sizes of borrowers and by an increase in bad loans most likely due to the reassessment of banks portfolios entry has a relatively persistent negative impact on credit supply to small and medium sized firms our results also show that concentration branch density and the share of branches of small banks affect the volumes of credit and bad loans of small borrowers
