capital inflows financial structure and housing booms we use a panel var to study the effect of shocks to capital inflows which are identified using sign restrictions on the housing market in oecd countries to explore how effects of these shocks change with the structure of the mortgage market and the degree of mortgage securitization we allow the var coefficients to vary with mortgage market characteristics our results indicate that capital inflow shocks have a significant and positive effect on real house prices real credit available to the private sector and real residential investment the responses of these variables are stronger in countries with more developed mortgage markets and in countries where securitization is allowed

structural interpretation of vector autoregressions with incomplete identification revisiting the role of oil supply and demand shocks traditional approaches to structural vector autoregressions vars can be viewed as special cases of bayesian inference arising from very strong prior beliefs these methods can be generalized with a less restrictive formulation that incorporates uncertainty about the identifying assumptions themselves we use this approach to revisit the importance of shocks to oil supply and demand supply disruptions turn out to be a bigger factor in historical oil price movements and inventory accumulation a smaller factor than implied by earlier estimates supply shocks lead to a reduction in global economic activity after a significant lag whereas shocks to oil demand do not

water pricing policies public decision making and farmers response implications for water policy abstract the problems caused by water scarcity demand important changes in the criteria and objectives of water policies the agricultural sector in spain consumes up to 80 of all available hydric resources and the need to increase the efficiency of current uses of water in the agricultural sector is at the core of the country s national water policy one alternative would be to resort to water pricing policies with the aim of providing incentives to save water consumption although it would inflict a certain degree of income losses to the farmers and raise the revenue collected by the water authorities the objective of this research is to analyze the effect caused by the application of different water pricing policies on water demand farmers income and the revenue collected by the government agency to undertake this analysis a dynamic mathematical programming model has been built that simulates farmers behavior and their response to different water pricing scenarios empirical application of the model has been carried out in several irrigation districts in spain covering varied farm regions and river basins results show that the effects of alternative pricing policies for irrigation water are strongly dependent on regional structural and institutional conditions and that changing policies produce distinct consequences within the same region and water district thus equivalent water charges would create widespread effects on water savings farm income and collected government revenue across regions and districts

how do fiscal and technology shocks affect real exchange rates new evidence for the united states abstract using vector autoregressions on u s time series relative to an aggregate of industrialized countries this paper provides new evidence on the dynamic effects of government spending and technology shocks on the real exchange rate and the terms of trade to achieve identification we derive robust restrictions on the sign of several impulse responses from a two country general equilibrium model we find that both the real exchange rate and the terms of trade whose responses are left unrestricted depreciate in response to expansionary government spending shocks and appreciate in response to positive technology shocks

a note on the causality between export and productivity abstract in this paper we re examine the export led growth hypothesis through testing granger causality from exports to labor productivity using the methodology developed in toda and yamamoto 1995

new evidence on the puzzles results from agnostic identification on monetary policy and exchange rates abstract past empirical research on monetary policy in open economies has found evidence of the delayed overshooting puzzle and the forward discount puzzle we revisit the effects of monetary policy on exchange rates by applying uhlig s uhlig h 2005a what are the effects of monetary policy on output results from an agnostic identification procedure journal of monetary economics 52 2 381 419 identification procedure that involves sign restrictions on the impulse responses of selected variables in a first step we leave the response of the exchange rate agnostically open and find sizeable evidence for both puzzles in a second step we additionally rule out the delayed overshooting by construction our results indicate that the forward discount puzzle is robust even without delayed overshooting

time varying dynamics of the real exchange rate an empirical analysis summary we use a time varying structural vector autoregression to investigate evolving dynamics of the real exchange rate for the uk euro area and canada we show that demand and nominal shocks have a substantially larger impact on the real exchange rate after the mid 1980s real exchange rate volatility relative to fundamentals also shows a marked increase after this point in time however there is some evidence suggesting a closer business cycle co movement of the real exchange rate and fundamentals simulations from an open economy dsge model show that these results are consistent with a decline in exchange rate pass through copyright 2012 john wiley sons ltd

inference in structural vector autoregressions when the identifying assumptions are not fully believed re evaluating the role of monetary policy in economic fluctuations abstract point estimates and error bands for svars that are set identified are only justified if the researcher is persuaded that some parameter values are a priori more plausible than others when such prior information exists traditional approaches can be generalized to allow for doubts about the identifying assumptions we use information about both structural coefficients and impacts of shocks and propose a new asymmetric t distribution for incorporating information about signs in a nondogmatic way we apply these methods to a three variable macroeconomic model and conclude that monetary policy shocks are not the major driver of output inflation or interest rates

macroeconomic factors and microlevel bank behavior we analyze the link between banks and the macroeconomy using a model that extends a macroeconomic var for the u s with a set of factors summarizing conditions in about 1 500 commercial banks we investigate how macroeconomic shocks are transmitted to individual banks and obtain the following main findings backward looking risk of a representative bank declines and bank lending increases following expansionary shocks forward looking risk increases following an expansionary monetary policy shock there is however substantial heterogeneity in the transmission of macroeconomic shocks which is due to bank size capitalization liquidity risk and the exposure to real estate and consumer loans

the time varying effect of oil price shocks on euro area exports abstract in this paper we provide novel evidence on changes in the relationship between the real price of oil and real exports in the euro area by combining robust predictions on the sign of the impulse responses obtained from a theoretical model with restrictions on the slope of the oil demand and oil supply curves we identify oil supply and foreign productivity shocks in a time varying var with stochastic volatility we find that from the 1980s onwards the relationship between oil prices and euro area exports has become less negative conditional on oil supply shortfalls and more positive conditional on foreign productivity shocks using the theoretical model we show that our empirical findings can be accounted for by i stronger trade relationship between the euro area and emerging economies ii a decrease in the share of oil in production and iii increased competitive pressures in the product market

money and liquidity effects separating demand from supply in the canonical monetary policy model money is endogenous to the optimal path for interest rates and output but when liquidity provision by banks dominates the demand for transactions money from the real economy money is likely to contain information for future output because of its impact on financial spreads and so we decompose broad money into primitive demand and supply shocks we find that supply shocks have played a significant role in the time series in each of the usa uk and eurozone in the short to medium term we further consider to what extent the supply of broad money is related to policy or to liquidity effects from financial intermediation

evidence on the relationship between housing and consumption in the united states a state level analysis we estimate the dynamic effects of u s housing market shocks on state level spending and home prices from a dynamic common factor model and identify housing demand and supply shocks using a sign restrictions approach while state level spending and house prices gradually respond positively and persistently to aggregate housing demand shocks there is significant variation across states in the magnitude of these responses cross state regressions of the estimated responses on an index of mortgage market development suggest that spending in states with greater opportunities for home equity borrowing is more sensitive to housing demand shocks than in states with fewer opportunities which is consistent with the prominence of a collateral channel over a wealth channel in explaining the link between housing and the overall economy

speculation in the oil market the run up in oil prices since 2004 coincided with growing investment in commodity markets and increased price co movement among different commodities we assess whether speculation in the oil market played a role in driving this salient empirical pattern we identify oil shocks from a large dataset using a dynamic factor model this method is motivated by the fact that a small scale vector autoregression is not informationally sufficient to identify the shocks the main results are as follows i while global demand shocks account for the largest share of oil price fluctuations speculative shocks are the second most important driver ii the increase in oil prices over the last decade is mainly driven by the strength of global demand however speculation played a significant role in the oil price increase between 2004 and 2008 and its subsequent collapse iii the co movement between oil prices and the prices of other commodities is mainly explained by global demand shocks our results support the view that the recent oil price increase is mainly driven by the strength of global demand but that the financialization process of commodity markets also played a role

international fiscal spillovers a two country business cycle model featuring nominal rigidities countercyclical mark ups rule of thumb consumers and government spending reversals is used to identify inequality predictions that are robust across a range of empirically plausible parameterizations these robust inequality restrictions are imposed onto a regime change factor model for the united states and its main trade partners to estimate the international fiscal spillovers the effects of u s government spending on foreign real activity are found to be sizable and significant operating mainly by lowering real interest rates rather than boosting trade balances in contrast there seems to be only limited evidence of state dependence in the international transmission of fiscal policy

does drawing down the us strategic petroleum reserve help stabilize oil prices we study the effects of releases from the us strategic petroleum reserve spr within the context of fully specified models of the global oil market that explicitly allow for storage demand as well as unanticipated changes in the spr we show that historically spr policy interventions defined as sequences of exogenous spr shocks during selected periods have helped stabilize the price of oil their effect on the price of oil however has been modest for example the cumulative effect of the spr releases after the invasion of kuwait in 1990 was a reduction of 2 per barrel in the real price of oil after 7 months whereas emergency drawdowns tend to lower the real price of oil we find that exchanges tend to raise the real price of oil in the long run we also provide a detailed analysis of the benefits of the 2018 white house proposal to sell off half of the spr within the next decade we show that the expected fiscal benefits of this plan are somewhat higher than the revenue of 16 6 billion dollars projected by the white house

identification of financial factors in economic fluctuations we estimate demand supply monetary investment and nancial shocks in a var identified with a minimum set of sign restrictions on us data we find that financial shocks are major drivers of fluctuations in output stock prices and investment but have a limited effect on inflation in a second step we disentangle shocks originating in the housing sector shocks originating in credit markets and uncertainty shocks in the extended set upfinancial shocks are even more important and a leading role is played by housing shocks that have large and persistent effects on output

asset prices news shocks and the trade balance we analyze the relationship between asset prices and the trade balance estimating a bayesian var for a broad set of 38 industrialized and emerging market countries to derive model based identifying restrictions we model asset price shocks as news shocks about future productivity in a two country dynamic stochastic general equilibrium model such shocks are found to exert sizable effects on the trade balance moreover the effects are highly heterogeneous across countries for instance following a news shock that implies on impact a 10 increase in domestic equity prices relative to the rest of the world the u s trade balance will worsen by up to 1 0 percentage points but much less so for most other economies we find that this heterogeneity appears to be linked to the financial market depth and equity home bias of countries moreover the channels via wealth effects and via the real exchange rate are important for understanding the heterogeneity in the transmission

dynamics of worker flows and vacancies evidence from the sign restriction approach this paper establishes robust dynamic features of the worker reallocation process in the us labor market i use structural vars with sign restrictions which take the form of restricting the short run negative relationship between vacancies and unemployment i e beveridge curve despite the weakness of these restrictions they reveal a clear unambiguous pattern that when unemployment increases and vacancies drop i both the separation rate and gross separations rise quickly and remain persistently high ii the job finding rate and vacancies drop in a hump shaped manner and iii gross hires respond little initially but eventually rise these results point to the importance of job loss in understanding us labor market dynamics this pattern also holds with respect to different kinds of shocks that induce the same beveridge curve relationship this paper also considers the disaggregate model which uses data disaggregated into six demographic groups and incorporates transitions into and out of the labor force i show that the separation rate continues to play a dominant role among prime age male workers while for other groups changes in the job finding rate are more important copyright 2009 john wiley sons ltd

multiple policy instruments for sustainable water management in crop production a modeling study for the chinese aksu tarim region china s crop production sector faces severe water scarcity issues previous research has shown that effective water conservation policies exert strongly negative impacts on agricultural production and farmers income which make them politically unfeasible under chinese conditions to highlight ways out of this dilemma the present study tests three alternative water policies complemented by supportive agricultural policies to reduce the trade offs between water conservation and rural development policy goals using the case of the extremely arid aksu tarim region in northwest china a regional supply model is developed which serves as the analysis framework applied as stand alone water policies irrigated area tax water quota and water pricing differ clearly in effectiveness and efficiency combined with agricultural policies subsidies into multiple policy instruments the price based and quota based instruments mitigate the negative impacts on rural development goals targeting a water conservation rate of 20 the tested multiple policies perform alike on the level of the entire study region cotton production decreases by 15 cereals production remains stable and regional income decreases by 13 however at the sub regional level the impacts on water conservation production and income differ significantly between the alternative policy instruments and sub regions constituting a crucial challenge for practical water policy implementation

business cycle measurement with some theory a method to evaluate cyclical models not requiring knowledge of the dgp and the exact specification of the aggregate decision rules is proposed we derive robust restrictions in a class of models use some to identify structural shocks in the data and others to evaluate the class or contrast sub models the approach has good properties even in small samples and when the class of models is misspecified the method is used to sort out the relevance of a certain friction the presence of rule of thumb consumers in a standard class of models

examining asymmetries in the transmission of monetary policy in the euro area evidence from a mixed cross section global var model abstract i estimate the transmission of a common euro area monetary policy shock across individual euro area economies to do so i develop a global var model in which all euro area economies are included individually while at the same time their common monetary policy is modelled as a function of euro area aggregate output growth and inflation the results suggest that the transmission of monetary policy across euro area economies displays asymmetries and that in line with economic theory these are driven by differences in economies structural characteristics in particular euro area economies in which a higher share of aggregate output is accounted for by sectors servicing interest rate sensitive demand exhibit a stronger transmission of monetary policy to real activity similarly even though the evidence is less conclusive euro area economies which feature more real wage and or fewer unemployment rigidities also appear to display a stronger transmission of monetary policy to real activity

what does a financial shock do first international evidence in this paper we attempt to evaluate the quantitative impact of financial shocks on key indicators of real activity and financial conditions we focus on financial shocks as they have received wide attention in the recent literature and in the policy debate after the global financial crisis we estimate a panel var for 21 advanced economies based on quarterly data between 1985 and 2011 where financial shocks are identified through sign restrictions we find robust evidence that financial shocks can be separately identified from other shock types and that they exert a significant influence on key macroeconomic variables such as gdp and particularly investment but it is unclear whether these shocks are demand or supply shocks from the standpoint of their macroeconomic impact the financial development and structure of a given country is found not to matter much for the intensity of the propagation of financial shocks moreover we generally find that these shocks play a role not only in crisis times but also in normal conditions finally we discuss the implications of our findings for monetary policy fabio fornari and livio stracca

does the source of oil price shocks matter for south african stock returns a structural var approach abstract in this paper we investigate the dynamic relationship between different oil price shocks and the south african stock market using a sign restriction structural var approach for the period 1973 01 to 2011 07 the results show that for an oil importing country like south africa stock returns only increase with oil prices when global economic activity improves in response to oil supply shocks and speculative demand shocks stock returns and the real price of oil move in opposite directions the analysis of the variance decomposition shows that the oil supply shock contributes more to the variability in real stock prices the main conclusion is that different oil price shocks affect stock returns differently and policy makers and investors should always consider the source of the shock before implementing a policy and making investment decisions

what lies beneath a time varying favar model for the uk transmission mechanism we use a time varying factor augmented var to investigate changes in the transmission mechanism of economic shocks in the uk our estimates demonstrate the importance of time variation and suggest that monetary policy shocks had a bigger impact on inflation equity prices and the exchange rate during the inflation targeting period changes in the transmission of policy shocks to bond yields point to more efficient management of long run inflation expectations finally we investigate responses of disaggregated prices with the median becoming more negative and cross sectional patterns consistent with a decrease in the role of cost channels

capital inflows and the u s housing boom we estimate an open economy vector autoregressive var model to study the effect of capital inflow shocks on the u s housing market we look at different external shocks that generate capital inflows to the u s in particular saving glut shocks and foreign monetary policy expansions the shocks are identified with theoretically robust sign restrictions derived from an open economy dynamic stochastic general equilibrium dsge model our findings suggest that capital inflows that result from saving glut shocks have a positive and persistent effect on real house prices and real residential investment

is the exchange rate a shock absorber or a source of shocks new empirical evidence this paper analyses the role of the real exchange rate in a structural vector autoregression framework for the united kingdom euro area japan and canada vis a vis the united states a new identification strategy is proposed building on sign restrictions the results are compared to the benchmark conventional approach of clarida and gali 1994 based on longrun zero restrictions although the restrictions are derived from the same theoretical model the results are strikingly different in contrast to the benchmark model an important role for nominal shocks in explaining real exchange rate fluctuations is found hence the exchange rate can rather be considered as a source of shocks instead of a shock absorber

the long run phillips curve a structural var investigation both cointegration methods and non cointegrated structural vars identified based on either long run restrictions or a combination of long run and sign restrictions are used in order to explore the long run trade off between inflation and the unemployment rate in the post wwii u s u k euro area canada and australia overall neither approach produces clear evidence of a non vertical trade off the extent of uncertainty surrounding the estimates is however substantial thus implying that a researcher holding alternative priors about what a reasonable slope of the long run trade off might be will likely not see her views falsified

mood swings and business cycles evidence from sign restrictions this paper provides new evidence that bouts of optimism and pessimism are an important source of u s business cycles using the identification schemes based on sign restrictions we document that identified optimism and pessimism shocks account for about 30 of u s business cycle fluctuations in hours and output in addition our empirical findings are consistent with the intensive and extensive margin adjustments in the u s labor market over business cycles providing further support to optimism shocks being an important source of u s business cycles the identified optimism shocks are at least partially rational as total factor productivity is found to rise 8 12 quarters after an initial bout of optimism while this later finding is consistent with some previous findings in the news shock literature we cannot rule out that such episodes reflect self fulfilling beliefs

narrative sign restrictions for svars we identify structural vector autoregressions using narrative sign restrictions narrative sign restrictions constrain the structural shocks and or the historical decomposition around key historical events ensuring that they agree with the established narrative account of these episodes using models of the oil market and monetary policy we show that narrative sign restrictions tend to be highly informative even a single narrative sign restriction may dramatically sharpen and even change the inference of svars originally identified via traditional sign restrictions our approach combines the appeal of narrative methods with the popularized usage of traditional sign restrictions

what caused the early millennium slowdown evidence based on vector autoregressions this paper uses a simple var for the usa and euro area to analyse the underlying shocks of the early millennium slowdown i e supply demand monetary policy and oil price shocks the results of two identification strategies are compared one is based on traditional zero restrictions and as an alternative an identification scheme based on more recent sign restrictions is proposed the main conclusion is that the recent slowdown is caused by a combination of several shocks negative aggregate supply and aggregate spending shocks the increase of oil prices in 1999 and restrictive monetary policy in 2000 these shocks are more pronounced in the usa than the euro area the results are somewhat different depending on the identification strategy it is illustrated that traditional zero restrictions can have an influence on the estimated impact of certain shocks copyright 2005 john wiley sons ltd

how do us credit supply shocks propagate internationally a gvar approach abstract we study how us credit supply shocks are transmitted to other economies we use the recently developed gvar approach to model financial variables jointly with macroeconomic variables in 33 countries for the period 1983 2009 we experiment with inter country links based on bilateral trade portfolio investment foreign direct investment and banking exposures capturing both bilateral trade and financial exposures in a gvar fits the data better than using trade weights only we use sign restrictions on the short run impulse responses in the us model to identify the credit supply shocks we find that negative credit supply shocks have strong negative effects on us and foreign gdp credit and equity markets in several countries respond clearly to the shocks exchange rate responses are consistent with a flight to quality to the us dollar the credit supply shocks explain about a fifth of one year ahead output forecast error variance in the us and about a tenth in the euro area and the uk but considerably less elsewhere

the effects of fiscal shocks on employment and the real wage we study the transmission of fiscal shocks in the labor market we employ a structural var and base identification on the restrictions that shocks to government consumption investment and employment must raise output and deficits these restrictions hold in both prototype real business cycle rbc and new keynesian models shocks to government consumption and investment increase real wages and employment contemporaneously both at state level and in the aggregate the dynamics in response to employment shocks are mixed increases in government employment raise the real wage and total employment in the aggregate however in one third of the states they reduce total employment

drawing conclusions from structural vector autoregressions identified on the basis of sign restrictions abstract this paper discusses the problems associated with using information about the signs of certain magnitudes as a basis for drawing structural conclusions in vector autoregressions we also review available tools to solve these problems for illustration we use dahlhaus and vasishtha s 2019 study of the effects of a u s monetary contraction on capital flows to emerging markets we explain why sign restrictions alone are not enough to allow us to answer the question and suggest alternative approaches that could be used

how do oil producers respond to oil demand shocks abstract this paper analyzes the response of international oil producers to demand induced changes in the price of crude oil during 1975 2011 focusing on potential differences between opec and non opec countries the goal is to derive consistent estimates of the short run price elasticity of crude oil supply at the country level i find that oil producers hardly respond to demand shocks within the same month and that the corresponding impact price elasticities of supply are statistically indistinguishable from zero while there is little evidence of differences in the dynamic responses to a typical flow demand shock on average over the sample period opec members seem to curtail production in response to a speculative demand shock whereas non opec production expands significantly flow and speculative demand shocks account for a nontrivial fraction of the total variability in country level crude oil supply

what drives oil prices emerging versus developed economies this paper explores the role of demand from emerging and developed economies as drivers of the real price of oil using a favar model that allows us to identify and compare demand from dierent groups of countries across the world we nd that demand from emerging economies most notably from asian countries is more than twice as important as demand from developed countries in accounting for the uctuations in the real price of oil and in oil production furthermore we

the transmission of international shocks to the uk estimates based on a time varying factor augmented var the aim of this paper is to gauge the importance of foreign demand supply and interest rate shocks on the uk economy and assess how their role has changed over time to that end we devise a time varying factor augmented var model that captures the relationship between 17 industrialised countries and the uk and accounts for any temporal evolution in this relationship the response of uk macroeconomic variables to a foreign interest rate shock is estimated to have changed significantly since the early 1990s international demand shocks play an important role in driving world and uk real activity especially during the recent recession

term structure surprises the predictive content of curvature level and slope summary this paper analyzes the predictive content of the term structure components level slope and curvature within a dynamic factor model of macroeconomic and interest rate data surprise changes of the three components are identified using sign restrictions and their macroeconomic underpinnings are studied via impulse response analysis the curvature factor is found to carry predictive information both about the future evolution of the yield curve and the macroeconomy in particular unexpected increases of the curvature factor precede a flattening of the yield curve and announce a significant decline of output more than 1 year ahead copyright 2010 john wiley sons ltd

disentangling the determinants of real oil prices in this study we quantify the impacts of economic fundamentals and derivative market speculation on the real price of crude oil using a structural var with sign restriction we determine that oil demand from the us and china particularly the latter one plays a crucial role in oil price changes after the year 2000 the contribution of speculation does not exceed 10 of oil price variations in our sample period

international spillovers from euro area and us credit and demand shocks a focus on emerging europe abstract in this paper we examine the international effects of contractions in loan supply loan demand and aggregate demand in the euro area and the usa all three shocks have been at the forefront in spreading stress during the period of the global financial crisis and in particular so to countries that are strongly integrated with the euro area we find that these shocks decrease international output and total credit to a varying degree loan demand and aggregate demand shocks in the euro area trigger significant negative spillovers on output in most other regions evidence for global negative output effects of euro area loan supply shocks is fraught with considerable estimation uncertainty when these three types of shocks emanate from the usa we find significant negative spillovers on output also for loan supply shocks in general international effects on total credit are an order of magnitude larger than those on output with again more evidence that is significant for us than euro area shocks last and taking a regional stance our results indicate that economies from emerging europe are most vulnerable to all shocks considered through their strong economic integration with the euro area these economies are likewise exposed to euro area and us shocks and spillover effects are often larger than the domestic response in the country of shock origin

what are the effects of fiscal policy shocks we propose and apply a new approach for analyzing the effects of fiscal policy using vector autoregressions specifically we use sign restrictions to identify a government revenue shock as well as a government spending shock while controlling for a generic business cycle shock and a monetary policy shock we explicitly allow for the possibility of announcement effects i e that a current fiscal policy shock changes fiscal policy variables in the future but not at present we construct the impulse responses to three linear combinations of these fiscal shocks corresponding to the three scenarios of deficit spending deficit financed tax cuts and a balanced budget spending expansion we apply the method to us quarterly data from 1955 to 2000 we find that deficit financed tax cuts work best among these three scenarios to improve gdp with a maximal present value multiplier of five dollars of total additional gdp per each dollar of the total cut in government revenue 5 years after the shock copyright 2009 john wiley sons ltd

integrating agri environmental programs into regional production models an extension of positive mathematical programming positive mathematical programming pmp has become a popular method for regional production models the standard approach estimates cost or production functions for each land use activity separately from each other this means that the same crop grown under two technologies is treated as if it were two separate crops which may lead to unsatisfying results for example if agri environmental programs are modeled we present an extended version of pmp that leads to more plausible results than the standard version in such cases the extended method is applicable to other problems where differences in the elasticity of substitution between activities are important

refining the workhorse oil market model the kilian and murphy journal of applied econometrics 2014 29 454 478 structural vector autoregressive model has become the workhorse model for the analysis of oil markets i explore various refinements and extensions of this model including the effects of 1 correcting an error in the measure of global real economic activity 2 explicitly incorporating narrative sign restrictions into the estimation 3 relaxing the upper bound on the impact price elasticity of oil supply 4 evaluating the implied posterior distribution of the structural models and 5 extending the sample i demonstrate that the substantive conclusions of kilian and murphy 2014 are largely unaffected by these changes

loan supply shocks during the financial crisis evidence for the euro area this paper employs a panel vector autoregressive model for the member countries of the euro area to explore the role of banks during the slump of the real economy that followed the financial crisis in particular we seek to quantify the macroeconomic effects of adverse loan supply shocks which are identified using sign restrictions we find that loan supply shocks significantly contributed to the evolution of the loan volume and real gdp growth in all member countries during the financial crisis however concerning both the timing and the magnitude of the shocks our results also indicate that the euro area was characterized by a considerable degree of cross country heterogeneity

technology shocks and robust sign restrictions in a euro area svar we use a model based identification strategy to estimate the impact of technology shocks on hours worked and employment in the euro area the sign restrictions applied in the vector autoregression var analysis are consistent with a large class of dynamic stochastic general equilibrium dsge models and are robust to parameter uncertainty the results are in line with the conventional real business cycle rbc interpretation that hours worked rise as a result of a positive technology shock by comparing the sign restrictions method to the long run restriction approach of gali quaterly journal of economics 1992 709 38 we show that the results do not depend on the stochastic specification of the hours worked series or the data sample but only on the identification scheme

the evolution of u s monetary policy 2000 2007 abstract a vector autoregression with time varying parameters is used to characterize changes in federal reserve policy that occurred from 2000 through 2007 and describe how they affected the performance of the u s economy declining coefficients in the model s estimated policy rule point to a shift in the fed s emphasis away from stabilizing inflation over this period more importantly however the fed held the federal funds rate persistently below the values prescribed by this rule under this more discretionary policy inflation overshot its target and the funds rate followed a path reminiscent of the stop go pattern that characterized fed behavior prior to 1979

the changing international transmission of financial shocks evidence from a classical time varying favar we study the changing international transmission of financial shocks over the period 1971 2012 global financial shocks are measured as unexpected changes of a u s financial conditions index fci developed by hatzius et al 2010 we model the fci jointly with a large international data set through a time varying parameter factor augmented var and find that financial shocks have a considerable impact on growth in the nine countries considered moreover financial shocks during the global financial crisis are found to be large by historical standards they explain approximately 20 of gdp growth variation on average over 2008 9 compared to an average of 5 prior to the crisis

measurement errors and monetary policy then and now should policymakers and applied macroeconomists worry about the difference between real time and final data we tackle this question by using a bayesian var with time varying parameters and stochastic volatility to show that the distinction between real time data and final data matters for the impact of monetary policy shocks the impact on final data is substantially and systematically different in particular larger in magnitude for different measures of real activity from the impact on real time data these differences have persisted over the last 40 years and should be taken into account when conducting or studying monetary policy

monetary policy and the exchange rate evaluation of var models abstract this paper examines the ability of vector autoregressive var models to properly identify the transmission of monetary policy in a controlled experiment simulating data from a small open economy dsge model estimated for australia we find that sign restricted var models do reasonably well at estimating the responses of macroeconomic variables to monetary policy shocks this is in contrast to models that use recursive zero type restrictions for which inflation can rise following an unexpected interest rate increase while the exchange rate can appreciate or depreciate depending on the ordering of the variables sign restricted var models seem to be able to overcome puzzles related to the real exchange rate provided that a sufficient number of different types of shocks are identified despite delivering the correct sign of the impulse responses central tendency measures of sign restricted var models can however be misleading and hardly ever coincide with the true impulses this finding casts doubt on the common notion that the median impulses are the most probable description of the true data generating process

changing macroeconomic dynamics at the zero lower bound this article develops a change point var model that isolates four major macroeconomic regimes in the us since the 1960s the model identifies shocks to demand supply monetary policy and spread yield using restrictions from a general equilibrium model the analysis discloses important changes to the statistical properties of key macroeconomic variables and their responses to the identified shocks during the crisis period spread shocks became more important for movements in unemployment and inflation a counterfactual exercise evaluates the importance of lower bond yield spread during the crises and suggests that the fed s large scale asset purchases helped lower the unemployment rate by about 0 6 percentage points while boosting inflation by about 1 percentage point

dynamic incentives by environmental policy instruments a survey abstract in this paper i survey and discuss recent developments on the incentives provided by environmental policy instruments for both adoption and development of advanced abatement technology a main conclusion to be drawn from the literature is that under competitive conditions market based instruments usually perform better than command and control moreover taxes may provide stronger long term incentives than tradable permits if the regulator is myopic if the government can anticipate new technology or is able to react on it optimally regulatory policies by virtue of administered prices taxes and policies by setting quantities issuing tradable permits are almost equivalent the literature also shows that under competitive conditions there is no difference between auctioning permits and grandfathering moreover timing and commitment of environmental policy is not crucial for adoption under competitive conditions commitment has positive incentive effects however if an r d sector has market power in the presence of market imperfections the ranking of the different policy instruments is ambiguous

labor supply factors and economic fluctuations we propose a new v ar identication scheme that enables us to disentangle labor supply shocks from wage bargaining shocks identication is achieved by imposing robust sign restrictions that are derived from a new keynesian model with endogenous labor force par ticipation according to our analysis on us data over the period 1985 2014 labor supply shocks and wage bargaining shocks are important drivers of output and unemployment both in the short run and in the long run these results suggest that identication strategies used in estimated new keynesian models to disentangle labor market shocks may be misguided we also analyze the behavior of the labor force participation rate through the lenses of our model wend that labor supply shocks are the main drivers of the participation rate and account for about half of its decline in the aftermath of the great recession

neutral technology shocks and the dynamics of labor input results from an agnostic identification this article studies the dynamic response of labor input to neutral technology shocks it uses benchmark dynamic stochastic general equilibrium models enriched with labor market search and matching frictions and investment specific technological progress that enables a new agnostic identification scheme based on sign restrictions on a structural vector autoregression svar the estimation supports an increase of labor input in response to neutral technology shocks this finding is robust across different perturbations of the svar model

multicrop production decisions in western irrigated agriculture the role of water price applying a model of the multioutput firm econometric results are reported for irrigated production in four multistate regions of the american west cross sectional microdata from the farm and ranch irrigation survey and limited dependent variable methods are used to estimate crop choice supply land allocation and water demand functions for field crops farm level water demand is decomposed into the sum of crop level water demands and crop level demands are further separated into an extensive margin land allocations and intensive margin short run water use response to water price measured as groundwater pumping cost occurs primarily at the extensive margin

the shortage of safe assets in the us investment portfolio some international evidence this paper develops a bayesian global var gvar model to track the international transmission dynamics of two stylized shocks namely a supply and demand shock to us based safe assets our main findings can be summarized as follows first we find that positive supply sided shocks lead to pronounced increases in economic activity which spills over to foreign countries the impact of supply sided shocks can also be seen for other quantities of interest most notably equity prices and exchange rates in europe second a demand sided shock leads to an appreciation of the us dollar and generally lower yields on us securities forcing investors to shift their portfolios towards foreign fixed income securities this yields sizable positive effects on us output equity prices and a general decrease in financial market volatility

computing productivity firm level evidence we explore the effect of computerization on productivity and output growth using data from 527 large us firms over 1987 1994 we find that computerization makes a contribution to measured productivity and output growth in the short term using one year differences that is consistent with normal returns to computer investments however the productivity and output contributions associated with computerization are up to five times greater over long periods using five to seven year differences the results suggest that the observed contribution of computerization is accompanied by relatively large and time consuming investments in complementary inputs such as organizational capital that may be omitted in conventional calculations of productivity the large long run contribution of computers and their associated complements that we uncover may partially explain the subsequent investment surge in computers in the late 1990s

testing the effect of investments in it and r d on labour productivity new method and evidence for indian firms abstract utilizing a micro level dataset of 900 firms for the period 2000 2016 from indian manufacturing this paper explores the effects of technological investments on labour productivity performance of firms by looking at investments in information technology it and research development r d the present study is the first to assess the role of it and r d jointly for indian manufacturing to control for transmission bias in production function estimation a gmm based one step control function estimator is applied we find large effects of both it and r d across various sub samples further our results imply that there is a complementarity between it and r d in generating labour productivity growth

assessing the economy wide effects of quantitative easing this article examines the macroeconomic impact of the first round of quantitative easing qe by the bank of england we attempt to quantify the effects of these purchases by focusing on the impact of lower long term interest rates on the wider economy we use three different models to estimate the impact of qe on output and inflation a large bayesian vector autoregression var a change point structural var and a time varying parameter var our estimates suggest that qe may have had a peak effect on the level of real gdp of around and a peak effect on annual cpi inflation of about points
