can financial intermediation induce endogenous fluctuations abstract this paper studies the possibility of endogenous fluctuations caused by activities of financial intermediaries risk averse agents borrow from banks and invest in a risky two state capital technology the probability of success with the technology is assumed to be decreasing in the amount of capital invested in a complete information setting with intermediation the efficient loan contract achieves complete risk sharing but the amount invested in the risky project is smaller than the loan size this income effect is responsible for the endogenous generation of complex dynamics in the absence of intermediation the economy studied cannot exhibit any cyclical fluctuations

a machine learning approach to identifying different types of uncertainty abstract we implement natural language processing techniques to extract uncertainty measures from federal reserve beige books between 1970 and 2018 business and economic related uncertainty is associated with future weakness in output higher unemployment and elevated term premia on the other hand political and government uncertainty while high during recent times has no statistically significant impact on the economy

optimal fiscal policy under multiple equilibria abstract we study optimal fiscal policy in an economy where i search frictions create a coordination problem and generate multiple pareto ranked equilibria and ii the government finances the provision of a public good by taxing market activity the government must choose the tax rate before it knows which equilibrium will obtain and therefore an important part of the problem is determining how the policy will affect the equilibrium selection process we show that when the equilibrium selection rule is based on the concept of risk dominance higher tax rates make coordination on the pareto superior outcome less likely as a result taking equilibrium selection effects into account leads to a lower optimal tax rate

the winner s curse experiments with buyers and with sellers this paper explores the winner s curse phenomena as it was studied experimentally by kagel and levin experiments with the winner s curse are complicated by the fact that subjects can lose money and the experimenter has only a limited means of collecting it from them thus subjects enjoy only limited liability which has theoretical implications for behavior in the kagel and levin experiments subjects were removed from the bidders competition after losses reached a predetermined value this experimental procedure has unknown implications for the results so ambiguity exists about whether the winner s curse was actually observed in this study their results were replicated in an environment in which subjects were not removed the case in which competitors are sellers is also studied bankruptcy cannot be a problem in sellers competition in both cases the winner s curse is observed thus the limited liability cannot be an explanation for the phenomenon reported by kagel and levin in addition the paper examines the bidding behavior of all individuals and shows that this behavior does not fit any of the tested theories either on the aggregate or individual level the winner s curse did not disappear over time during the conduct of the research

the effects of economic policy uncertainty on china s economy evidence from time varying parameter favar this article explores the effects of china s economic policy uncertainty epu on its fiscal policy monetary policy and a wide range of macro economic variables using a time varying parameter fava

commodity price changes and the predictability of economic policy uncertainty in this study we forecast economic policy uncertainty epu using input on 23 commodity price changes we reveal the significant predictability of epu using three forecast combinations this indicates that commodity price changes can be taken as a leading indicator of epu

efficiency in auctions with private and common values an experimental study this discussion has resulted in a publication in the american economic review 2002 92 3 625 43 auctions are generally not efficient when the object s expected value depends on private and common value information we report a series of first price auction experiments to measure the degree of inefficiency that occurs with financially motivated bidders while some subjects fall prey to the winner s curse they weigh their private and common value information in roughly the same manner as rational bidders with observed efficiencies close to predicted levels increased competition and reduced uncertainty about the common value positively affect revenues and efficiency the public release of information about the common value also raises efficiency although less than predicted

a hybrid fiat commodity monetary system in this paper i describe a monetary system in which backing is provided for the government s liabilities by way of contingent resort to taxes the system is studied within the context of a one good pure exchange model of two period lived overlapping generations in which aside from various uniform boundedness assumptions considerable diversity is allowed both within and across generations two results are established i the existence of at least one perfect foresight competitive equilibrium and ii the pareto optimality of any such equilibrium the monetary system studied has some of the features of a commodity money system with a large seignorage spread between bid and ask prices one crucial feature of the system is that the government by taxing stands ready at any time to convert its outstanding liabilities into the commodity at an announced price in an important sense the hybrid scheme is a mixture of a fixed supply fiat scheme and a pure tax transfer scheme a social security scheme it makes some use of market pricing of net government indebtedness and some use of taxes and transfers its one advantage vis a vis the fixed supply fiat scheme is that any equilibrium under the hybrid scheme is pareto optimal for the fixed supply fiat scheme one can at best demonstrate that there exists an optimal equilibrium it is well known that there can exist nonoptimal equilibria under that scheme the presumed advantage of the hybrid scheme vis a vis the pure tax transfer scheme is its lesser use of taxes and transfers i say presumed because the framework i set out is not rich enough to imply that less use of taxes and transfers is preferable to more use of taxes and transfers

can the seller benefit from an insider in common value auctions abstract in existing models of first price common value auctions heterogeneous bidder information characterized by a well informed insider is detrimental to the seller s revenue we show that this is not a general principle the linkage effect of increased information identified by milgrom and weber has force in our model of heterogeneous bidders and dominates any adverse effects of an insider on revenues in addition a bidder with garbled information can profit in a first price auction if his information is private and an inside bidder may prefer to have less information about the outside bidder s signal journal of economic literature classification numbers d44 d82

bank regulation as an antidote to price level instability abstract we use an overlapping generations model with a risky storage technology to describe a new type of sunspot equilibrium characterized by excessive price level volatility and overinvestment in stored goods the features of this equilibrium lead us to interpret it as involving speculation and as arising when banks create excessive quantities of money this interpretation provides welfare justification for imposing quantity limits on the bank money stock we argue that the monetary regime established in england under peel s act imposed such a quantity limit our findings support quantity theorists traditional view that the possibility of overissue provides a rationale for bank regulation

an empirical study of an auction with asymmetric information this paper examines federal auctions for drain age leases on the outer continental shelf from 1959 to 1969 these are leases that are adjacent to tracts on which a deposit has been discovered the authors find that the data strongly support the hypotheses that neighbor firms are better informed about the value of a lease than nonneighbor firms that neighbor firms coordinate their bidding decisions and that both types of firms bid strategically in accordance with the bayesian nash equilibrium model for first price sealed bid auctions with asymmetric information

is the relationship between gold and the u s dollar always negative the role of macroeconomic uncertainty abstractthe main work of this article is to access the role of macroeconomic uncertainty in effecting the correlation between gold and the dollar the empirical analysis is divided into two parts firstly we examine the impact of macroeconomic uncertainty on short and long correlation between gold and the dollar secondly we analyse the explanatory power of economic uncertainty for the abnormal market relation between gold and the dollar with a threshold model in particular we investigate impacts of economic uncertainty sourced from different economies the empirical results indicate that economic uncertainty generates direct impacts on the correlation between gold and the dollar moreover our results emphasize that uncertainty sourced from different economies have different impacts on the dynamics between gold and the dollar this article also presents the relative contribution of gold and the dollar shocks to the likelihood of being in the high uncertainty regime these results have implications fo

interdependent value auctions with insider information theory and experiment abstract we develop a model of interdependent value auctions in which two types of bidders compete insiders who are perfectly informed about their value and outsiders who are informed only about the private component of their value because the bidding strategy of outsiders cannot efficiently adjust with that of insiders the second price auction is inefficient the english auction has an equilibrium in which the information outsiders infer from the history of drop out prices enables them to bid toward attaining efficiency the presence of insiders has positive impacts on the seller s revenue a laboratory experiment confirms key theoretical predictions despite evidence of naive bidding

the relationships among expected inflation disagreement and uncertainty evidence from matched point and density forecasts abstract this paper examines matched point and density forecasts of inflation from the survey of professional forecasters to analyze the relationships among expected inflation disagreement and uncertainty we undertake the empirical analysis within a seemingly unrelated regression framework and derive measures of uncertainty using a decomposition proposed by wallis 2004 2005 and by drawing on the concept of entropy the results offer little evidence that disagreement is a useful proxy for uncertainty and mixed evidence that increases in expected inflation are accompanied by heightened uncertainty conversely we document a quantitatively and statistically significant positive association between disagreement and expected inflation

dynamic connectedness of uncertainty across developed economies a time varying approach abstract economic uncertainty has attracted a significant part of the modern research in economics proving to be a significant factor for every economy in this study we focus on the transmission channel of uncertainty between developed economies examining potential spillover effects between the u s the e u the u k japan and canada within a time varying framework our empirical results indicate of a significant spillover of uncertainty from the e u to the u s

dynamics of oil price precious metal prices and exchange rate this study examines the co movements and information transmission among the spot prices of four precious metals gold silver platinum and palladium oil price and the us dollar euro exchange rate we find evidence of a weak long run equilibrium relationship but strong feedbacks in the short run the spot precious metal markets respond significantly but temporarily to a shock in any of the prices of the other metal prices and the exchange rate furthermore we discover some evidence of market overreactions in the palladium and platinum cases as well as in the exchange rate market in conclusion whether there are overreactions and re adjustments or not investors may diversify at least a portion of the risk away by investing in precious metals oil and the euro policy implications are provided

5 information impact and allocation rules in auctions with affiliated private values a laboratory study in affiliated private value auctions each bidder has perfect information regarding his her own value for the object at auction but higher values of the item for one bidder make higher values for other bidders more likely we report on a series of experiments examining three key implications of these auctions i in a first price auction public information about rivals values increases expected revenue ii an english auction increases expected revenue compared to a first price auction and iii a second price auction is isomorphic to an english auction in examining these issues we compare predictions of some ad hoc bidding models with nash equilibrium predictions in the first price auction experiments nash equilibrium bidding theory organizes the data better than either of two ad hoc bidding models public information about others valuations does increase average revenue but the increase in revenue is smaller and less reliable than predicted under risk neutral nash equilibrium bidding lower average revenue might be attributed to risk aversion while the high variability is attributed to a sizable frequency of individual bidding errors relative to the theory bidding theory precisely organizes english auction outcomes after a brief initial learning period the dominant strategy equilibrium does not organize second price auctions nearly as well as market prices persistently exceed predicted prices the difference between english and second price outcomes is attributed to effects of different information flows inherent in the structure of the two institutions on eliminating bidding errors revenue impacts of these two institutions relative to a first price auction are examined in light of observed bidding patterns

legal restrictions sunspots and cycles abstract an economy in which legal restrictions prevent private agents from issuing close substitutes for money is examined specifically in a model with borrowing and lending agents are prevented from acquiring privately issued liabilities in amounts smaller than some minimum dollar denomination an economy is then constructed which has no sunspot equilibria absent such a restriction in the presence of the restriction however conditions sufficient to rule out equilibrium 2 cycles also imply the existence of stationary sunspot equilibria this is the case even though all agents have savings functions that are non decreasing in relevant rates of return

asymmetric english auctions abstract this paper studies equilibria of the n bidder single object english or open ascending price auction in a setting with interdependent values and asymmetric bidders maskin in h siebert ed privatization institut fur weltwirtschaften der universitat kiel kiel 1992 pp 115 136 showed that if the values satisfy a single crossing condition then the two bidder english auction has an efficient equilibrium in this paper two extensions of the single crossing condition the average crossing condition and the cyclical crossing condition are introduced the main result is that under either of these conditions the n bidder english auction has an efficient equilibrium

the real bills doctrine versus the quantity theory a reconsideration two competing monetary policy prescriptions are analyzed within the context of overlapping generations models the real bills prescription is for unfettered private intermediation or central bank operations designed to produce the effects of such intermediation the quantity theory prescription in contrast is for restrictions on private intermediation designed to separate money from credit although our models are consistent with quantity theory predictions about money supply and price level behavior under these two policy prescriptions the models imply that the quantity theory prescription is not pareto optimal and the real bills prescription is

credit and economic activity credit regimes and nonlinear propagation of shocks in this paper we examine empirically whether credit plays a role as a nonlinear propagator of shocks this propagation takes the form of a threshold vector autoregression in which a regime change occurs if credit conditions cross a critical threshold using nonlinear impulseresponse functions we evaluate the dynamics implied by the threshold model these suggest that shocks have a larger effect on output in the tight credit regime than is normally the case and that contractionary monetary shocks typically have a larger effect than expansionary shocks finally using a nonlinear version of historical decompositions we attempt to determine the relative contribution to output growth of shocks and the nonlinear structure

dynamic co movements of stock market returns implied volatility and policy uncertainty we examine time varying correlations among stock market returns implied volatility and policy uncertainty our findings suggest that correlations are indeed time varying and sensitive to oil demand shocks and us recessions

some anecdotal evidence relating to the legal restrictions theory of the demand for money according to the legal restrictions theory of the demand for money characteristics such as denomination and negotiability of interest bearing debt are what prevents it from being employed as a transactions medium during the years 1915 27 the government of france used as a financing instrument securities that by the legal restrictions theory should have circulated in exchange an experience by eleanor lansing dulles attempting to use one of these securities in a purchase as well as other evidence suggests that they did not

economic policy uncertainty shocks and stock bond correlations evidence from the us market abstract this paper examines the effects of economic policy uncertainty shocks on stock bond correlations for the us market we devise a general framework which distinguishes a positive shock from a negative one and nests either as its special case the results show that innovations in the policy uncertainty index impact negatively and asymmetrically on the subsequent stock bond correlations which are characterized by a structural break and positive type asymmetry

how does economic policy uncertainty drive gold stock correlations evidence from the uk abstractin this article we investigate the effects of economic policy uncertainty epu on correlations between the uk stock market and gold market we find that less certain economic policies result in lower correlations while more certain economic policies result in higher correlations the correlations are symmetric and show no structural breaks caused by the recent financial crisis the recent financial crisis has not changed epu effects on the correlations the effects of one positive one standard deviation shock of the logarithmic change rate of the epu on the correlations last approximately 19 months

cross country determinants of economic policy uncertainty spillovers this study explores the determinants of cross country economic policy uncertainty epu spillovers we find that bilateral factors such as trade and common language play a highly significant role i

where to draw lines stability versus efficiency what kinds of assets should financial intermediaries be permitted to hold what kinds of liabilities should they be allowed to issue should a government or a central bank offer explicit deposit insurance or implicit deposit insurance by acting as a lender of last resort this paper reviews how tensions involving stability versus efficiency and regulation versus laissez faire have for centuries run through macroeconomic analysis of these questions

a dynamic equilibrium model of search bargaining and money abstract this paper considers dynamic equilibria in a model with random matching strategic bargaining and money equilibrium in the bargaining game is characterized in terms of a simple differential equation when we embed this characterization into the monetary economy the model can generate outcomes such as limit cycles that never arise if one imposes a myopic nash bargaining solution as has been done in the past journal of economic literature classification numbers c78 d83 e31

auctions and the price of art the value of most important works of art is established by public auction either directly by an actual sale or indirectly by reference to other sales how the auction system works is thus a critical determinant of how the public s preferences are translated into the evaluation of artistic work the auction system is central in the determination of the incentives for artistic work and the efficiency of the auction system is a key determinant of the cost of creating and distributing works of art this paper contains a review of the burgeoning new research of the last decade that has been designed to shed light on how the art auction system actually works what it indicates about price formation and how well it performs we begin our discussion in section 2 with a short description of the mechanics of the auction system and then organize the remainder of our discussion around two major topics the first topic concerns how auction prices can be used to determine and compare overall price movements within the art market and other markets and the second topic concerns how the auction mechanism influences prices we

economic policy uncertainty in the us does it matter for the euro area abstract we investigate the effects of a us economic policy uncertainty shock on some euro area macroeconomic aggregates via structural vars we model the indicators of economic policy uncertainty recently developed by baker et al 2013 jointly with the aggregate price indexes and alternative indicators of the business cycle for the two above indicated economic areas according to our svars a one standard deviation shock to us economic policy uncertainty leads to a statistically significant fall in the european industrial production and prices of 0 12 and 0 06 respectively the contribution of the us uncertainty shock on the european aggregates is shown to be quantitatively larger than the one exerted by an euro area specific uncertainty shock

an experimental analysis of auctions with interdependent valuations abstract we study experiments in an auction setting with interdependent valuation groups of three players receive private signals and then bid for a single indivisible item valuations for the item differ within groups and depend asymmetrically on a bidder s own and other bidders signals theoretically the english auction yields efficient allocations while other standard auction formats fail to do so consistent with equilibrium predictions we find that an english auction yields significantly more efficiency than a second price sealed bid auction we also study the seller s expected revenue and the bidders expected profits and find that the experimental results are close to the theoretical predictions

equilibria in open common value auctions abstract a sufficient condition for uniqueness of nash equilibrium in second price common value auctions is identified we establish that there exists a continuum of equilibria in irrevocable exit common value auctions for the case of two bidders we provide plausible sufficient conditions under which the expected seller revenue is maximized at the symmetric equilibrium an example in which the auctioneer s revenue at the symmetric equilibrium in a second price auction is strictly greater than the revenue at many asymmetric equilibria in the corresponding irrevocable exit auction is provided

measuring financial asset return and volatility spillovers with application to global equity markets we provide a simple and intuitive measure of interdependence of asset returns and or volatilities in particular we formulate and examine precise and separate measures of return spillovers and volatility spillovers our framework facilitates study of both non crisis and crisis episodes including trends and bursts in spillovers and both turn out to be empirically important in particular in an analysis of sixteen global equity markets from the early 1990s to the present we find striking evidence of divergent behavior in the dynamics of return spillovers vs volatility spillovers return spillovers display a gently increasing trend but no bursts whereas volatility spillovers display no trend but clear bursts

two period cycles in a three period overlapping generations model abstract we study the properties of two period monetary cycles in simple pure exchange overlapping generations economies in which the households live for three periods we demonstrate that these economies can support cycles under a much broader and arguably more plausible range of assumptions than the analogous two period economies we show that economies that fail the well known grandmont econometrica 53 1985 995 condition can have cycles and that economies that satisfy the condition can fail to have cycles in addition we show that economies can have monetary cycles when they do not have conventional monetary steady states and when aggregate demand for assets is not decreasing in the real return rate at a gross real rate of unity

macroeconomic policy uncertainty shocks on the chinese economy a gvar analysis abstractthis article studies the spillovers of economic policy uncertainty epu from developed economies to china in terms of the source extent and persistence by estimating a global vector autoregressive gvar model with both financial and trade variables acting as the transmission channels our findings confirm the existence of international transmissions of policy uncertainty while the patterns differ markedly the us epu appears to be the most significant cause of the fall of export industrial production equity price and exchange rate meanwhile the eu epu is also to be blamed for the depreciation of rmb in contrast to industrial production which shows the largest negative impact chinese inflation increases to a relatively smaller extent with the epu shocks ranking as the us japanese and the eu regardless of the minor impact on a long term interest rate the short term interest rate in china reacts positively to the european and us epu shocks despite the independent national monetary poli

legal restrictions sunspots and peel s bank act the real bills doctrine versus the quantity theory reconsidered this paper considers two questions i what is the purpose of legal restrictions intended to separate money from credit markets and ii is such a separation desirable it is argued that historical legal restrictions meant to achieve such a separation were designed to preclude the occurrence of sunspot equilibria it is also shown that a coherent model can be constructed in which sunspot equilibria exist in the absence of legal restrictions but not if money and credit markets are separated nevertheless there is no obvious welfare justification for such a separation

asymmetric correlations in gold and other financial markets abstractin this article we implement a recently developed statistical method to test asymmetries in cross asset correlations focusing in particular on the gold market our empirical results provide evidence that gold exhibits asymmetric correlations with stocks and the u s dollar but not with bonds furthermore splitting the sample into three characteristic periods we find that exceedance correlations exhibit substantial time variation even in similar market tensions for same pairs of assets our findings imply that investors and fund managers should take into account the asymmetric dependence structure which depends on the upside or downside of the market

measuring cross category spillovers of policy specific uncertainty in china abstract this paper examine cross category spillovers of policy specific uncertainty in china we find that monetary policy and exchange rate policy are net givers while fiscal policy and trade policy are net receivers monetary policy plays the dominant role spillovers are countercyclical

the effect of succession taxes on family firm investment evidence from a natural experiment this paper provides causal evidence on the impact of succession taxes on firm investment decisions and transfer of control using a 2002 policy change in greece that substantially reduced the tax on intrafamily transfers of businesses i show that succession taxes lead to a more than 40 decline in investment around family successions slow sales growth and a depletion of cash reserves furthermore succession taxes strongly affect the decision to sell or retain the firm within the family i conclude by discussing implications of my findings for firms in the united states and europe

interest rate rules vs money growth rules a welfare comparison in a cash in advance economy abstract this paper considers the welfare consequences of two particularly simple rules for monetary policy an interest rate peg and a money growth peg the model economy consists of a real side that is the standard real business cycle model and a monetary side that amounts to imposing cash in advance constraints on certain market transactions the paper also considers the effect of assuming a rigidity in the typical household s cash savings choice the competitive equilibrium of the economy is not pareto efficient partly because of two distortions a distortion on the capital accumulation decision and a distortion on portfolio choice that arises from the assumed rigidity the principal result of the paper is that the interest rate rule but not the money growth rule entirely eliminates these two distortions and is thus the benevolent central banker s policy choice

the value of an informed bidder in common value auctions abstract i compare two information structures in a common value first price auction with two bidders in one each of the two bidders knows only his own signal about the value of the object and in the other one of the bidders learns his opponent s signal as well gaining the additional information in the second information structure makes the informed bidder worse off if the value is submodular in the bidders signals and better off if it is supermodular if the value is supermodular then the seller s revenue tends to be lower with the informed bidder than without

the international transmission of volatility shocks an empirical analysis this paper proposes an empirical model which can be used to estimate the international transmission of volatility shocks using this model we estimate that a one standard deviation increase in the volatility of the shock to us real gdp leads to a decline in uk gdp of 1 relative to trend and a 0 7 increase in uk cpi relative to trend at the two year horizon using a nonlinear open economy dsge model we find that these empirical estimates are consistent with the response to a perturbation to the volatility of foreign supply type shocks while an increase in the volatility of demand shocks has a negligible impact

international spillovers of policy uncertainty using the baker et al 2013 index of policy uncertainty for six developed countries this paper estimates spillovers of policy uncertainty we find that spillovers account for slightly more than one fourth of the dynamics of policy uncertainty in these countries with this share rising to one half during the financial crisis the us and uk are responsible for a large fraction of the spillovers since the financial crisis while the remaining countries are all net receivers of policy uncertainty shocks during and after this period

on international uncertainty links bart based empirical evidence for canada we use the indexes of economic policy uncertainty epu developed by baker et al 2015 for canada and seven china france germany japan russia united kingdom and united states other countries to study international uncertainty links by means of a bayesian additive regression trees bart algorithm using partial dependence plots relative importance measures and permutation tests we shed light on how epu in canada is linked to epu in seven other countries

the price of gold and the exchange rate abstract this paper examines the theoretical relationship between the major exchange rates and the prices of internationally traded commodities in the empirical section the case of gold is analyzed using forecast error data among other things it is found that since the dissolution of the bretton woods international monetary system floating exchange rates among the major currencies have been a major source of price instability in the world gold market and as the world gold market is dominated by the european currency bloc appreciations or depreciations of european currencies have strong effects on the price of gold in other currencies
