us monetary policy and sectoral commodity prices abstract using a structural var svar model we examine the effects of the monetary policy of the united states on sectoral commodity prices including the non fuel commodity prices food prices beverage prices prices of agricultural raw materials prices of metals and prices of fuel energy commodities and macroeconomic activity the empirical evidence suggests that a u s monetary contraction leads to an immediate rise in the broad commodity price index which possibly reflects an aggregation bias greater expected inflation and speculation high production costs or some overshooting due to overreactions then the response erodes after six quarters as the positive interest rate shock vanishes and higher interest rates and liquidity drainage take traction despite this the aggregate price response masks the existence of significant heterogeneity in the price responses of the different types of commodity sectors more specifically a positive interest rate shock leads to i an initial pop in the price returns of the non fuel commodities which later reverses path and becomes negative as in the case of the prices of agricultural raw materials ii a positive and persistent rise in the volatile food prices iii a fall in the beverage prices and iv a persistent reduction in the prices of metals and the prices of energy prices our results also remain globally intact with respect to alternative specifications and identification schemes as well as to unconventional monetary policy effects similar results are also found when commodity futures prices are used we conclude that policymakers should recognize the source of sector inflation before embarking on contractionary monetary policy the design of core inflation targeting is also preferable to headline inflation targeting

district magnitude and representation of the majority s preferences evidence from popular and parliamentary votes representatives have more effective incentives to cater to the preferences of the majority of citizens when they are elected in districts with few rather than many seats we investigate this hypothesis empirically by matching swiss members of parliament s voting behavior on legislative proposals with real referendum outcomes on the same issues for the years 1996 to 2008 we thus identify the impact of district magnitude on representatives incentives to adhere to citizens revealed preferences we find systematic statistically significant and economically relevant evidence that individual representatives from districts with few seats vote more often in line with majority preferences

central bank announcements of asset purchases and the impact on global financial and commodity markets abstract we present evidence on the effects of large scale asset purchases by the federal reserve and the bank of england since 2008 we show that announcements about these purchases led to lower long term interest rates and depreciations of the u s dollar and the british pound on announcement days while commodity prices generally declined despite this more stimulative financial environment we suggest that lsap announcements likely involved signaling effects about future growth that led investors to downgrade their u s growth forecasts lowering long term us yields depreciating the value of the u s dollar and triggering a decline in commodity prices moreover our analysis illustrates the importance of controlling for market expectations when assessing these effects we find that positive u s monetary surprises led to declines in commodity prices even as long term interest rates fell and the u s dollar depreciated in contrast on days of negative u s monetary surprises i e when markets evidently believed that monetary policy was less stimulatory than expected long term yields the value of the dollar and commodity prices all tended to increase

does proportional representation foster closer congruence between citizens and policy makers this article assesses the claim that proportional representation pr fosters a closer correspondence between the views of citizens and the positions of the government the study uses the comparative study of electoral systems data set and compares respondents self placements on a left right scale with placements of cabinet parties locations in 31 election studies the authors argue that pr has two contradictory consequences on one hand pr leads to more parties and more choice for voters but these parties are less centrist and this increases the overall distance between voters and parties on the other hand pr increases the likelihood of coalition governments this pulls the government toward the center of the policy spectrum and reduces the distance between the government and voters these two contradictory effects of pr wash out and the net overall impact of pr on congruence is nil the data support the authors interpretation

proportionality and turnout evidence from french municipalities many studies find that voter turnout is higher in proportional representation pr elections than in plurality elections but because the two systems differ in multiple ways and are used in differe

liquidity and the dynamic pattern of asset price adjustment a global view abstract global liquidity expansion has been very dynamic since 2001 contrary to conventional wisdom high money growth rates have not coincided with a concurrent rise in goods prices at the same time however asset prices have increased sharply significantly outpacing the subdued development in consumer prices we investigate the interactions between money and goods and asset prices at the global level using aggregated data for major oecd countries our var results support the view that different price elasticities on asset and goods markets explain the observed relative price change between asset classes and consumer goods

why are crude oil prices high when global activity is weak abstract there have been substantial increases in liquidity in recent years and real oil prices have almost returned to the high levels achieved before the global financial crisis unanticipated increases in global real m2 led to statistically significant increases in real oil prices the historical impact of global real m2 on the real price of crude oil is important in the recovery of oil prices over 2009 to 2011

effectiveness of electoral systems for reducing government corruption a game theoretic analysis abstract a theoretical model is developed for predicting the relative effectiveness of different electoral systems for reducing government corruption we consider voting games in which parties with known corruption levels and known positions on a major policy question compete for legislative seats we find that approval voting and proportional representation are fully effective in the sense that all equilibria exclude corrupt parties from legislative seats plurality voting is partly effective in the sense that there always exist some equilibria that exclude corrupt parties borda voting is ineffective because for some political situations no equilibria can guarantee the exclusion of corrupt parties journal of economic literature classification number d72

time varying yield curve dynamics and monetary policy monetary policy the yield curve and the private sector behaviour of the us economy are modelled as a time varying structural vector autoregression the monetary policy shocks of the early 1980s explain a large portion of the persistence of inflation and the level of the term structure changes in inflation expectations implied by the yield curve account for the persistence of the federal funds rate failures of the expectations hypothesis are rare and coincided with the credibility building of paul volcker s fed tenure at the beginning of the 1980s and the sequence of consecutive policy rate cuts around the time of the early 1990s recession copyright 2009 john wiley sons ltd

estimating the dynamics and persistence of financial networks with an application to the sterling money market summary we propose a novel methodology for dynamic econometric modelling of large financial networks subject to persistence structural changes and sparsity we estimate bivariate dynamic tobit type models for each pair of banks allowing for deterministic or stochastic time varying parameters and then aggregate across all bank pairs to tackle the high dimensionality of the model we construct a few lagged variables that efficiently summarize the position of a bank pair in the network we propose a simple and computationally easy kernel based local maximum likelihood estimator of the time varying parameters of the model and establish its asymptotic properties we then apply the model to the time series of daily overnight money market network in the uk 2003 2012 the results show that our model can successfully accommodate the numerous structural breaks arising from changes to the monetary framework and captures well the dynamics of the interbank lending relationships in this period copyright 2015 john wiley sons ltd

a time varying parameter structural model of the uk economy abstract we estimate a time varying parameter structural macroeconomic model of the uk economy using a bayesian local likelihood methodology this enables us to estimate a large open economy dsge model over a sample that comprises several different monetary policy regimes and an incomplete set of data our estimation identifies a gradual shift to a monetary policy regime characterised by an increased responsiveness of policy towards inflation alongside a decrease in the inflation trend down to the two percent target level the time varying model also performs remarkably well in forecasting and delivers statistically significant accuracy improvements for most variables and horizons for both point and density forecasts compared to the standard fixed parameter version

var analysis and the great moderation post world war ii us macroeconomic history is usually divided into two distinct subperiods the former period which extends up to the end of the volcker disinflation is characterized by a significant extent of macroeconomic turbulence with highly volatile inflation and output growth the latter period from the end of the volcker disinflation up to the present day is marked in contrast by significantly smaller volatilities for both inflation and output growth these dramatic changes in the reduced form properties of the us economy over the last several decades char acterize a phenomenon known as the great moderation see in particular chang jin kim and charles nelson 1999 margaret mcconnell and gabriel perez quiros 2000 a vast empirical literature has investigated the source s of the great moderation in an attempt to disentangle the relative contributions of two main explanations good policy and good luck based on time varying or markov switching structural var methods the good luck hypoth esis has been advocated by a number of authors including james h stock and mark w watson 2003 giorgio e primiceri 2005 christopher sims and tao zha 2006 and luca gambetti evi pappa and fabio canova 2008

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

incumbent performance and electoral control in the pure theory of electoral competition citizens compare the platforms of the candidates and vote for the one whose platform is preferred candidate strategies are identified with promises about future performance in office models of this sort have been developed in both static mckelvey 1975 and dynamic kramer 1977 i settings and all appear to have the property that if the set of alternatives is large enough in some sense equilibrium platforms rarely exist but these models have another feature that is quite as disturbing as their instability in the static setting discussed by mckelvey little attention is paid to the possibility that once in office the politician s preferences may diverge from those of his constituents and that he may therefore choose policies at variance from his platform instead it is simply assumed that promises will be kept whether or not such behavior is congruent with the interest of the officeholder it is sometimes argued that an enforcement mechanism may exist to discipline politicians for failing to keep promises but without a specification of the mechanism it is not obvious that it would be in the interests of the

not all sectors are alike differential impacts of shocks in oil prices on the sectors of the colombian economy abstract in this paper an estimation of differential impacts of shocks in oil prices on the economic sectors in the oil exporting colombia is made using data from the world economy and adopting the model of structural autoregressive vectors var employed by kilian et al 2009 oil prices shocks are estimated according to three types of origin oil supply oil demand and aggregate demand subsequently using data from the colombian economy the effects that these shocks have on sectoral production in colombia are estimated through the use of var models which allow direct impacts to be separated from those that are transmitted through the interrelations between sectors the results obtained show that only the specific demand for oil and aggregate demand shocks affect significantly the total production in colombia although not in all sectors only manufacturing industry and electricity gas and water sectors are directly and significantly affected by both types of demand shocks however when considering the indirect effects transmitted through the interrelations between sectors it was found that the total impacts of these two types of shocks affect the construction transport and trade restaurants and hotels sectors as the effect is positive the colombian economy benefits from increases in oil prices due to demand factors but responds negatively when the opposite situation occurs

the time varying volatility of macroeconomic fluctuations we investigate the sources of the important shifts in the volatility of us mac roeconomic variables in the postwar period to this end we propose the esti mation of dsge models allowing for time variation in the volatility of the structural innovations we apply our estimation strategy to a large scale model of the business cycle and find that shocks specific to the equilibrium condition of investment account for most of the sharp decline in volatility of the last two decades jel c51 e32

labor supply of politicians using data on members of the european parliament meps we examine the impact of salaries on the composition and the behavior of legislators employing a differences in differences approach we exploit the introduction of a law that equalized meps salaries which had previously differed by as much as a factor of 10 increasing salaries raises the fraction of meps who run for re election but decreases the quality of elected meps proxied by college quality salary has no discernible impact on effort or legislation output higher salaries induce more political competition

the electoral sweet spot low magnitude proportional electoral systems can electoral rules be designed to achieve political ideals such as accurate representation of voter preferences and accountable governments the academic literature commonly divides electoral systems into two types majoritarian and proportional and implies a straightforward trade off by which having more of an ideal that a majoritarian system provides means giving up an equal measure of what proportional representation pr delivers we posit that these trade offs are better characterized as nonlinear and that one can gain most of the advantages attributed to pr while sacrificing less of those attributed to majoritarian elections by maintaining district magnitudes in the low to moderate range we test this intuition against data from 609 elections in 81 countries between 1945 and 2006 electoral systems that use low magnitude multimember districts produce disproportionality indices almost on par with those of pure pr systems while limiting party system fragmentation and producing simpler government coalitions

regime switches agents beliefs and post world war ii u s macroeconomic dynamics the evolution of inflation and output over the last 50 years is examined through the lens of a micro founded model that allows for changes in the behavior of the federal reserve and in the volatility of structural shocks agents are aware of the possibility of regime changes and their beliefs have an impact on the law of motion underlying the macroeconomy the results support the view that there were regime switches in the conduct of monetary policy however the behavior of the federal reserve is identified by repeated fluctuations between a hawk and a dove regime instead of by the traditional pre and post volcker structure counterfactual simulations show that if agents had anticipated the appointment of an extremely conservative chairman inflation would not have reached the peaks of the late 70s and the inflation output trade off would have been less severe these beliefs counterfactuals are new in the literature finally the paper provides a bayesian algorithm to handle the technical difficulties that arise in a rational expectations model with markov switching regimes

transparency political polarization and political budget cycles in oecd countries we investigate the effects of fiscal transparency and political polarization on the prevalence of electoral cycles in fiscal balance while some recent political economy literature on electoral cycles identifies such cycles mainly in weak and recent democracies in contrast we show conditioning on a new index of institutional fiscal transparency that electoral cycles in fiscal balance are a feature of many advanced industrialized economies using a sample of 19 oecd countries in the 1990s we identify a persistent pattern of electoral cycles in low er transparency countries while no such cycles can be observed in high er transparency countries furthermore we find in accordance with recent theory that electoral cycles are larger in politically more polarized countries

has monetary policy become more effective we investigate the implications of changes in the structure of the u s economy for monetary policy effectiveness estimating a vector autoregression over the pre and post 1980 periods we provide evidence of a reduced effect of monetary policy shocks in the latter period we estimate a structural model that replicates well the economy s response in both periods and perform counterfactual experiments to determine the source of the change in the monetary transmission mechanism and in the economy s volatility we find that by responding more strongly to inflation expectations monetary policy has stabilized the economy more effectively in the post 1980 period

political selection under alternative electoral rules we study the patterns of political selection in majoritarian versus proportional systems political parties face a trade off in choosing the mix of high and low quality candidates high quality candidates are valuable to voters and thus help to win elections but they crowd out loyal candidates who are most preferred by the parties under proportional representation politicians selection depends on the share of swing voters in the entire electorate in majoritarian elections it depends also on the distribution of competitive versus safe single member districts we show that a majoritarian system with only a few competitive districts is less capable of selecting good politicians than a proportional system as the share of competitive districts increases the majoritarian system becomes more efficient than the proportional system however for a large enough share of competitive districts a non monotonic relation arises the marginal positive effect of adding high quality politicians on the probability of winning the election is reduced and highly competitive majoritarian systems become less efficient than proportional ones in selecting good politicians

electoral reform and trade offs in representation we examine the effect of electoral institutions on two important features of representation that are often studied separately policy responsiveness and the quality of legislators theoretically we show that while a proportional electoral system is better than a majoritarian one at representing popular preferences in some contexts this advantage can come at the price of undermining the selection of good politicians to empirically assess the relevance of this trade off we analyze an unusually controlled electoral reform in switzerland early in the twentieth century to account for endogeneity we exploit variation in the intensive margin of the reform which introduced proportional representation based on administrative constraints and data on voter preferences a difference in difference analysis finds that higher reform intensity increases the policy congruence between legislators and the electorate and reduces legislative effort contemporary evidence from the european parliament supports this conclusion

estimating the evolution of money s role in the u s monetary business cycle we assess money s role in the post wwii u s business cycle by employing both fixed coefficient and rolling window bayesian estimations of a structural model of the business cycle with money our empirical evidence favors a specification with drifting parameters for money consumption nonseparability and the federal reserve s reaction to nominal money growth the role of money is estimated to have been important during the 1970s and declined afterward the omission of money produces severely distorted impulse response functions relative to the model with money money is found to be important in replicating the u s output volatility during the great inflation

trend inflation indexation and inflation persistence in the new keynesian phillips curve purely forward looking versions of the new keynesian phillips curve nkpc generate too little inflation persistence some authors add ad hoc backward looking terms to address this shortcoming we hypothesize that inflation per sistence results mainly from variation in the long run trend component of inflation which we attribute to shifts in monetary policy we derive a version of the nkpc that incorporates a time varying inflation trend and examine whether it explains the dynamics of inflation when drift in trend inflation is taken into account a purely forward looking version of the model fits the data well and there is no need for backward looking components jel e12 e31 e52 in this paper we consider the extent to which guillermo calvo s 1983 model of nominal price rigidities can explain inflation dynamics without relying on arbitrary backward looking terms in its baseline formulation the calvo model leads to a purely forward looking new keynesian

the macroeconomics of trend inflation most macroeconomic models for monetary policy analysis are approximated around a zero inflation steady state but most central banks target an inflation rate of about 2 percent many economists have recently proposed even higher inflation targets to reduce the incidence of the zero lower bound constraint on monetary policy in this survey we show that the conduct of monetary policy should be analyzed by appropriately accounting for the positive trend inflation targeted by policymakers we first review empirical research on the evolution and dynamics of u s trend inflation and some proposed new measures to assess the volatility and persistence of trend based inflation gaps we then construct a generalized new keynesian model that accounts for a positive trend inflation in this model an increase in trend inflation is associated with a more volatile and unstable economy and tends to destabilize inflation expectations this analysis offers a note of caution regarding recent proposals to address the existing zero lower bound problem by raising the long run inflation target jel e12 e31 e32 e52 e58

democracy redistribution and political participation evidence from sweden 1919 1938 in this paper we compare how two different types of political regimes direct versus representative democracy redistribute income toward the relatively poor segments of society after the introduction of universal and equal suffrage swedish local governments are used as a testing ground since this setting offers a number of attractive features for a credible impact evaluation most importantly we exploit the existence of a population threshold which partly determined a local government s choice of democracy to implement a regression discontinuity design the results indicate that direct democracies spend 40 60 percent less on public welfare our interpretation is that direct democracy may be more prone to elite capture than representative democracy since the elite s potential to exercise de facto power is likely to be greater in direct democracy after democratization

the computational experiment an econometric tool an economic experiment consists of the act of placing people in an environment desired by the experimenter who then records the time paths of their economic behavior performing experiments that use actual people at the level of national economies is obviously not practical but constructing a model economy and computing the economic behavior of the model s people is such experiments are termed computational this essay specifies the steps in designing a computational experiment to address some well posed quantitative question the authors emphasize that the computational experiment is an econometric tool used in the task of deriving the quantitative implications of theory

structural changes in the us economy is there a role for monetary policy this paper investigates the contribution of monetary policy to the changes in output growth and inflation dynamics in the us we identify a policy shock and a policy rule in at ime varying coefficients var using robust sign restrictions the transmission of policy shocks has been relatively stable the variance of the policy shock has decreased over time but policy shocks account for a small fraction of the level and of the variations in inflation and output growth volatility and persistence we find little evidence of a significant increase in the long run response of the interest rate to inflation a more aggressive inflation policy in the 1970s would have produced large output growth costs

how do electoral systems affect fiscal policy evidence from cantonal parliaments 1890 2000 using a new data set on swiss cantons since 1890 we analyze how the adoption of proportional representation affects fiscal policy in line with economic theory we show that proportional systems shift spending toward broad goods like education and welfare benefits but decrease spending on geographically targetable goods like roads we find little evidence that proportional representation increases the overall size of government an analysis of the underlying theoretical mechanisms reveals that proportional representation increases electoral turnout left wing representation and political fragmentation these changes in political representation explain a substantial share of the rise in education spending but a small share of the rise in welfare spending or the decline in road expenditures jel h4 h11 i38

electoral rules and political selection theory and evidence from a field experiment in afghanistan voters commonly face a choice between competent candidates and those with policy preferences similar to their own this article explores how electoral rules such as district magnitude mediate this trade off and affect the composition of representative bodies and the quality of policy outcomes we show formally that anticipation of bargaining over policy causes voters in elections with multiple single member districts to prefer candidates with polarized policy positions over more competent candidates results from a unique field experiment in afghanistan are consistent with these predictions specifically representatives selected by elections with a single multi member district are better educated and exhibit less extreme policy preferences
