the open economy consequences of u s monetary policy a failure to identify movements in the federal funds rate that are both unpredictable and independent of other determinants of open economy variables may lead to attenuation bias in the estimated effects of u s monetary policy on the exchange rate and foreign variables using a u s monetary policy measure which isolates unpredictable and independent federal funds rate changes we quantify the magnitude of the attenuation bias for the exchange rate and foreign variables the exchange rate appreciation following a monetary contraction is up to 4 times larger than a recursively identified var estimate there is stronger evidence of foreign interest rate pass through the expenditure reducing effects of a u s monetary policy contraction dominate any expenditure switching effects leading to a positive conditional correlation of international outputs and prices we compare our results with those obtained using identification based upon 1 non recursive var restrictions and 2 restrictions derived from high frequency asset price behavior

group lending repayment incentives and social collateral abstract in this paper we investigate the impact on repayment rates of lending to groups which are made jointly liable for repayment this type of scheme especially in the guise of the grameen bank in bangladesh has received increasing attention we set up and analyze the repayment game which group lending gives rise to our analysis suggests that such schemes have both positive and negative effects on repayment rates the positive effect is that successful group members may have an incentive to repay the loans of group members whose projects have yielded insufficient return to make repayment worthwhile the negative effect arises when the whole group defaults even when some members would have repaid under individual lending we also show how group lending may harness social collateral which serves to mitigate its negative effect

some empirical evidence on the effects of shocks to monetary policy on exchange rates this paper investigates the effects of shocks to u s monetary policy on exchange rates we consider three measures of these shocks orthogonalized shocks to the federal funds rate orthogonalized shocks to the ratio of nonborrowed to total reserves and changes in the romer and romer index of monetary policy in sharp contrast to the literature we find substantial evidence of a link between monetary policy and exchange rates specifically according to our results a contractionary shock to u s monetary policy leads to i persistent significant appreciations in u s nominal and real exchange rates and ii significant persistent deviations from uncovered interest rate parity in favor of u s interest rates

why interest rates react to money announcements an explanation from the foreign exchange market abstract when the fed announces a money supply greater than had been expected interest rates rise why one explanation is that the market raises its estimate of the future rates of money growth and inflation and bids up nominal interest rates we offer contrary evidence on such days the dollar appreciates not depreciates an alternative explanation is that the market perceives the change in the money stock as a transitory fluctuation that the fed will reverse in the future the anticipated future tightening raises today s real interest rate causes a capital inflow and appreciates the dollar the result in fact observed

international spillovers of large scale asset purchases this paper evaluates the international spillover eects of large scale asset purchases lsaps using a two country dynamic stochastic general equilibrium model with nominal and real rigidities and portfolio balance eects portfolio balance eects arise from imperfect substitution between short and long term bond portfolios in each country as well as between domestic and foreign bonds within these portfolios we show that lsaps lower both domestic and foreign long term yields and stimulate economic activity in both countries international spillover eects

on the policy ineffectiveness proposition and a keynesian alternative a rejoinder i the basis of rush and waldo s rw results is the introduction of a war dummy variable in the dg equation this is however difficult to justify in the context of a rational expectations model under incomplete learning wars by their very nature are unique events and it is not clear how the public are supposed to learn the quantitative effects that the ending of three totally different wars may have had upon the growth of real government expenditure the fact that in i946 the public knew that world war ii was over does not mean that they could also estimate its precise quantitative effect on government expenditure rw estimate their dg equation using data for the whole of the period i943 73 and i943 85 thus implicitly assuming that all these data were available to the public in i946 for the computation of the coefficient of the war dummy in the dg equation but in i946 the public could not possibly have known about the timing and the intensities of the korean or the vietnam wars the assumption of complete learning that underlies the rational expectations hypothesis in general and rw s version of the nc model in particular is especially troublesome when the model contains dummy variables that correspond to unique events

mainstreaming microfinance social performance management or mission drift summary what scope is there for the pursuit of explicit development goals in the context of increasing integration of specialized microfinance and commercial banking sectors this question and the idea of mission drift is first analyzed using a model that distinguishes between institutions financial and social performance possibilities preferences and assessment systems the model is used to review findings from action research with an international sample of poverty oriented microfinance institutions that suggest some simple steps for improved social performance management it is then used to illustrate the relationship between social and financial performance more widely across the retail financial services sector and to offer pointers for more policy analysis at this level

interpreting the macroeconomic time series facts the effects of monetary policy existing theory and evidence on the effects of monetary policy are reviewed substantial room for disagreement among economists remains new evidence based on multivariate time series studies of several countries is presented while certain patterns in the data consistent with effective monetary policy are strikingly similar across countries others particularly the tendency of interest rate increases to predict high inflation are harder to reconcile with effective monetary policy

a critique of the proposed tests of the natural rate rational expectations hypothesis the failure of the governments of most industrialised countries over the past decade to deal successfully with the problems of rising unemployment and high and often accelerating rates of price and wage inflation has revived interest in the pre keynesian macro economics of sound money and has renewed the controversy of the 1930 s over what governments should or should not do if they wish to achieve full employment with reasonable price stability in democratic societies keynesian economics has come under attack both by those who primarily oppose interventionist policies on ideological grounds and by the so called new classical macro economists who adhere to the natural rate of unemployment hypothesis nrh advanced by phelps i967 and friedman i 968 and the hypothesis of rational formation of expectations reh originally due to muth i96i armed with this joint natural rate rational expectations nr re hypothesis the new classical macro economists have argued that in a world capable of being represented by linear or log linear relations with a unique and stable equilibrium and no information discrepancy between the government and the private sector no government macro economic policy whether monetary or fiscal no matter how ingeniously formulated and how effectively implemented can have any systematic or lasting impact upon the level of output or the rate of unemployment 2 clearly this fundamental policy

credit constraints credit unions and small scale producers in guatemala abstract efficient and equitable development outcomes may depend in part on whether formal financial institutions leave low wealth producers tightly constrained in their access to credit if so can cooperative institutions efficiently relax these constraints these issues are explored using survey data gathered from 950 small scale producer households in areas of guatemala with market oriented credit unions that mobilize savings and make unsubsidized loans nonprice rationing by banks is found to be common among lower wealth households while credit unions relax credit constraints for a significant portion of those rationed by banks but not the poorest of the study households

real exchange rate monetary policy and the u s economy evidence from a favar model this paper examines the effects of exchange rate depreciation to the u s economy in a factor augmented vector autoregression model using monthly data of 148 variables for the post bretton woods period of 1973 2017 exchange rate shock is identified to reflect exogenous disturbances to the foreign exchange market and movements in exchange rate that are not accounted for by changes in the u s monetary policy we find that depreciation is expansionary and inflationary to the broad u s economy the current account improves over time conforming to the j curve theory and monetary policy is leaning against the wind jel e3 e5 f31 f32 f41

to bi or not to bi differences between spillover estimates from bilateral and multilateral multi country models abstract asymptotic analysis and monte carlo simulations show that spillover estimates obtained from widely used bilateral such as two country var models are in general less accurate both in terms of bias and mean squared error than those obtained from multilateral such as global var models in particular the accuracy of spillover estimates obtained from bilateral models depends on two aspects of economies integration with the rest of the world first accuracy worsens as direct bilateral transmission channels become less important for example when the spillover sender accounts only for a small share of the spillover recipient s overall integration with the rest of the world second accuracy worsens as indirect higher order spillovers and spillbacks become more important for example when the spillover recipient is more integrated with the rest of the world overall empirical evidence on the global output spillovers from us monetary policy is consistent with these generic results spillover estimates obtained from two country var models are systematically smaller than those obtained from a global var model and the differences between spillover estimates obtained from two country var models and a global var model are more pronounced for economies for which the us accounts for a smaller share of their overall trade and financial integration with the rest of the world and for economies which are more integrated with the rest of the world overall

unit root hypothesis new classical and keynesian models abstract following perron econometrica 1989 57 1361 1401 the variables in the new classical and keynesian output equations are shown to be trend stationary therefore these models are evaluated for the united states with the standard non nested hypothesis tests the majority of these tests have rejected the new classical in favour of the keynesian approach

global liquidity transmission to emerging market economies and their policy responses abstract this paper analyzes the transmission of global liquidity gl from advanced economies aes to emerging market economies emes we distill gl momenta from the macro financial data of aes through a factor model and identify them with sign restrictions as policy driven market driven and risk averseness factors using a panel factor augmented var analysis we then investigate eme responses to shocks to gl momenta a positive shock to policy driven liquidity boosts growth in emes elevating stock prices and currency values while a shock to risk averseness has a largely opposite effect a market driven gl expansion boosts stock markets and lowers funding costs increasing competitiveness and current account balance inflation targeting emes are found to fare better than emes under alternative regimes in terms of macro financial volatility

microfinance mission drift summary claims have been made that microfinance institutions mfis experience mission drift as they increasingly cater to customers who are better off than their original customers we investigate mission drift using average loan size as a main proxy and the mfis lending methodology main market and gender bias as further mission drift measures we employ a large data set of rated multi country mfis spanning 11 years and perform panel data estimations with instruments we find that the average loan size has not increased in the industry as a whole nor is there a tendency toward more individual loans or a higher proportion of lending to urban costumers regressions show that an increase in average profit and average cost tends to increase average loan and the other drift measures more focus should be given to cost efficiency in the mfi

the risk taking channel of monetary policy in the u s evidence from corporate loan data to study the presence of a risk taking channel in the u s we build a comprehensive data set from the syndicated corporate loan market and measure monetary policy using different measures most notably taylor 1993 and romer and romer 2004 residuals we identify a negative relation between monetary policy rates and bank risk taking especially in the run up to the 2007 financial crisis however this effect is purely supply side driven only when using taylor residuals and an ex ante measure of bank risk taking our results highlight the sensitivity of the potency of the risk taking channel to the measures of monetary policy innovations

federal reserve information and the behavior of interest rates this paper tests for the existence of asymmetric information between the federal reserve and the public by examining federal reserve and commercial inflation forecasts it demonstrates that the federal reserve has considerable information about inflation beyond what is known to commercial forecasters it also shows that monetary policy actions provide signals of the federal reserve s information and that commercial forecasters modify their forecasts in response to those signals these findings may explain why long term interest rates typically rise in response to shifts to tighter monetary policy jel e52 e43 d82 asymmetric information between the federal reserve and the public is a phenomenon that is often posited but rarely tested numerous models of central bank behavior for example show that the existence of asymmetric information has important implications for the effectiveness of policy and the consequences of dynamic inconsistency yet there

international welfare effects of monetary policy abstract in this paper i examine the international welfare effects of monetary policy i develop a new keynesian two country model where central banks in both countries follow the taylor rule i show that a decrease in the domestic interest rate under producer currency pricing is a beggar thyself policy that reduces domestic welfare and increases foreign welfare in the short term regardless of whether the cross country substitutability is high or low in the medium term it is a beggar thy neighbour beggar thyself policy if the marshall lerner condition is satisfied violated under local currency pricing a decrease in the domestic interest rate is a beggar thy neighbour policy in the short term but a beggar thyself policy in the medium term both under producer and local currency pricing a monetary expansion increases world welfare in the short term but reduces it in the medium term

the relevance of unanticipated money growth in explaining output variation this paper tests a reduced form equation in which real gnp for the united states is explained by deviations of multi period m1 growth rates from ex ante expectations of those rates formed from one to eight quarters earlier the theoretical model is suggested by stanley fischer s 1977 article and may be thought of as a new keynesian model the equations are tested in both level and first difference specifications to allow for possible unit roots empirical results strongly support this model in preference to new classical and keynesian alternatives ex ante expectations or m1 growth are formed from multi period forecasts made by chase econometrics inc between 1970 and 1979

financial performance and outreach a global analysis of leading microbanks microfinance contracts have proven able to secure high rates of loan repayment in the face of limited liability and information asymmetries but high repayment rates have not translated easily into profits for most microbanks profitability though is at the heart of the promise that microfinance can deliver poverty reduction while not relying on ongoing subsidy the authors examine why this promise remains unmet for most institutions using a data set with unusually high quality financial information on 124 institutions in 49 countries they explore the patterns of profitability loan repayment and cost reduction the authors find that institutional design and orientation matter substantially lenders that do not use group based methods to overcome incentive problems experience weaker portfolio quality and lower profit rates when interest rates are raised substantially for these individual based lenders one key to achieving profitability is investing more heavily in staff costs a finding consistent with the economics of information but contrary to the conventional wisdom that profitability is largely a function of minimizing cost

microenterprise finance is there a conflict between growth and poverty alleviation abstract microenterprise finance has generated enormous enthusiasm among aid donors and nongovernment organizations ngos as an instrument for reducing poverty in a manner that is financially self sustaining although something of a consensus has emerged concerning the principles by which such institutions should be designed however we know little about their impact the paper reports on a research project which estimated the impact of 13 microfinance institutions in seven developing countries on poverty and other target variables and attempted to relate such impact to the institutions design features for each of the institutions studied the impact of lending on the recipient household s income tended to increase at a decreasing rate as the recipient s income and asset position improved a relationship which can easily be explained in terms of the greater preference of the poor for consumption loans their greater vulnerability to asset sales forced by adverse income shocks and their limited range of investment opportunities there are significant outliers to this general pattern in particular very poor people who have been able to achieve significant loan impact but they are the exception rather than the rule and the relationship is significant at the 1 level for all the institutions studied except the malawi mudzi fund this relationship defines in the short term an impact frontier which serves as a tradeoff lenders can either focus their lending on the poorest and accept a relatively low total impact on household income or alternatively focus on the not so poor and achieve higher impact the position and slope of the estimated impact curve vary however with the design of the institution for well designed schemes impact at all levels of income is higher than for ill designed schemes hence for many lender institutions the tradeoff can often be moved by appropriate innovations in institutional design in particular modifications to savings loan collection and incentive arrangements for borrowers and staff

econometric issues in macroeconomic models with generated regressors the paper critically reviews the literature on the econometric issues raised by the use of generated regressors gr in empirical models the economic rationale for the use of gr is considered with examples being drawn from several macroeconomic examples including new classical macroeconomic ncm models which postulate monetary neutrality various estimation methods are discussed for models which include surprise or unexpected terms and the strengths and weaknesses of each approach are investigated drawing upon the work of mcaleer and mckenzie 1991 situations where the typically inefficient two step estimation 2se method will be efficient are highlighted problems of model misspecification and measurement errors are also investigated an empirical section highlights some of the dangers of using uncorrected 2se estimation results through a careful consideration of many recent attempts to test the ncm monetary neutrality hypothesis copyright 1993 by blackwell publishers ltd

an alternative explanation of the price puzzle abstract this paper proposes an explanation for the frequent appearance of a price puzzle in vars designed for monetary policy analysis it assumes that the data are generated by a model in which output and output gap are not equivalent while an econometrician follows the common practice of including only output in the var the omission of the output gap is shown to spuriously produce a price puzzle and several other incorrect conclusions in a class of commonly used models this can happen even if the model admits a triangular identification and if the forecasts produced by the misspecified var are optimal when the model is tested on us data all predictions are supported a commodity price index is not needed to solve the puzzle

monetary policy surprises and interest rates evidence from the fed funds futures market abstract this paper estimates the impact of monetary policy actions on bill note and bond yields using data from the futures market for federal funds to separate changes in the target funds rate into anticipated and unanticipated components interest rates response to anticipated target rate changes is small while their response to unanticipated changes is large and highly significant these responses are generally consistent with the expectations hypothesis of the term structure surprise target rate changes have little effect on expectations of future actions however which helps to explain the lack of empirical support for the expectations hypothesis at the short end of the yield curve

non nested tests of three competing theories of business cycles this paper tests the keynesian new classical and real business cycle theories against each other as non nested hypotheses using quarterly data for the us covering the period 1959 1 1989 2 the results indicate that no one theory stands out as the dominant explanation of the business cycle this contrasts with the findings of earlier work which is mostly concerned with testing the keynesian against the new classical theory we find that the introduction of a third theory the real business cycle theory which accounts of real factors blurs the distinction between the demand sided keynesian and the new classical theories

monetary policy in a data rich environment abstract most empirical analyses of monetary policy have been confined to frameworks in which the federal reserve is implicitly assumed to exploit only a limited amount of information despite the fact that the fed actively monitors literally thousands of economic time series this article explores the feasibility of incorporating richer information sets into the analysis both positive and normative of fed policymaking we employ a factor model approach developed by stock j h watson m w diffusion indices journal of business economic statistics 2002 20 2 147 forecasting inflation 1999 journal of monetary economics 44 2 293 that permits the systematic information in large data sets to be summarized by relatively few estimated factors with this framework we reconfirm stock and watson s result that the use of large data sets can improve forecast accuracy and we show that this result does not seem to depend on the use of finally revised as opposed to real time data we estimate policy reaction functions for the fed that take into account its data rich environment and provide a test of the hypothesis that fed actions are explained solely by its forecasts of inflation and real activity finally we explore the possibility of developing an expert system that could aggregate diverse information and provide benchmark policy settings

identifying vars based on high frequency futures data abstract using the prices of federal funds futures contracts we measure the impact of the surprise component of federal reserve policy decisions on the expected future trajectory of interest rates we show how this information can be used to identify the effects of a monetary policy shock in a standard var this alternative approach to identification is quite different and we argue more plausible than the conventional identifying restrictions we find that a usual recursive identification of the model is rejected as is any identification that insists on a monetary policy shock having an exactly zero effect on prices contemporaneously we nevertheless agree with the conclusion of much of the var literature that only a small fraction of the variance of output can be attributed to monetary policy shocks

on the policy ineffectiveness proposition and a keynesian alternative one of the most controversial macroeconomic developments of the last decade has been the rise of the so called new classical nc approach to macroeconomic theory and policy lucas i972 sargent and wallace i975 and barro i 976 have presented models which combine the friedman i968 phelps i970 natural rate theory with assumptions of market clearing and rational expectations as is well known these models deliver the striking result that the mean values of real variables cannot be affected by the government s monetary policy the publication of the theoretical work establishing the impotency result led to much empirical testing of the nc models one of the most successful approaches from the point of view of nc advocates is contained in a series of papers by barro i977 i978 i98i barro and rush i980 and rush i986 recently pesaran i982 has questioned barro s results and claimed that once an implausible assumption is discarded barro s work can be rejected in favour of a keynesian alternative because pesaran has put forth an explicit counter model to barro s work his results are potentially quite important this paper examines in detail pesaran s work and conclusions

the nature of the adas model based on the islm model the aggregate demand and supply model adas is interpreted as a synthesis of the keynesian and neoclassical models it uses the islm model without explaining its nature to derive aggregate demand ad it is combined with an aggregate supply as curve to explain price inflation and output dynamics this paper argues that neither the ad nor as curve is conceptually the same as its microeconomic counterpart and adas is not a synthesis in fact adasimplies that discretionary policy is necessary and that price changes do not perform their traditional negative feedback function

do microfinance institutions accomplish their mission evidence from the relationship between traditional financial sector development and microfinance institutions outreach and performance this article analyses the relationship between outreach and performance of microfinance institutions mfis on the one hand and traditional financial sector development on the other the results indicate that mfis reach more clients and are more profitable in countries where access to the traditional financial system is low this finding is in line with the market failure hypothesis mfis respond to a need that banks do not fulfill and mfis flourish where the formal financial sector fails along the same line the results demonstrate that mfis serve poorer people in countries with well developed financial systems the results suggest that in countries with well developed financial systems the two sectors stand in more direct competition with each other this competition pushes mfis down the market and makes mission drift by mfis less likely

on the robustness of barro s new classical unemployment model in this paper the robustness of barro s new classical model of unemployment is examined using both two and three equation systems to various sample periods and methods of estimation the methods of estimation used are two step ols two step ols with correct standard errors using the same and different numbers of observations for the expectations and structural equations full information maximum likelihood and four novel variants of the computationally intensive parametric bootstrap method not surprisingly the empirical results for barro s model change according to the sample period chosen the different methods of estimation and the different ways of computing the covariance matrix for purposes of inference however the empirical results and inferences are generally robust to variations in any or all of these options
