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

euler equations and money market interest rates a challenge for monetary policy models standard macroeconomic models equate the money market rate targeted by the central bank with the interest rate implied by a consumption euler equation we use u s data to calculate the interest rates implied by euler equations derived from a number of specifications of household preferences correlations between these euler equation rates and the federal funds rate are generally negative regression results and impulse response functions imply that the spreads between the euler equation rates and the federal funds rate are systematically linked to the stance of monetary policy our findings pose a fundamental challenge for models that equate the two

trade offs and depletion in choice abstract four experiments examine why choices deplete executive resources the authors show that the resolution of trade offs is a driver of depletion effects arising from choice and the larger the trade offs the greater is the depletion effect the authors also find that choice difficulty not related to trade offs does not influence the depleting effect of the choices finally the authors find that though people can intuit some depletion effects they do not intuit that choices or trade offs within choices might be depleting and therefore fail to predict that larger trade offs are more depleting

monetary aggregates and liquidity in a neo wicksellian framework woodford 2003 describes a popular class of neo wicksellian models in which monetary policy is characterized by an interest rate rule and the money market and financial institutions are typically not even modeled critics contend that these models are incomplete and unsuitable for monetary policy evaluation our banks and bonds model starts with a standard neo wicksellian model and then adds banks and a role for bonds in the liquidity management of households and banks the banks and bonds model gives a more complete description of the economy but the neo wicksellian model has the virtue of simplicity our purpose here is to see if the neo wicksellian model gives a reasonably accurate account of macroeconomic behavior in the more complete banks and bonds model we do this by comparing the models second moments variance decompositions and impulse response functions we also study the role of monetary aggregates in predicting inflation in the two models

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

consumer preference for a no choice option the traditional focus in the decision making literature has been on understanding how consumers choose among a given set of alternatives the notion that preference uncertainty may lead to choice deferral when no single alternative has a decisive advantage is tested in seven studies building on recent research the article shows that the decision to defer choice is influenced by the absolute difference in attractiveness among the alternatives provided and is not consistent with trade off difficulty or the theory of search these findings are then extended to show that choice deferral can also be modified for the same alternatives by manipulations that make them appear more similar in attractiveness or that decrease the need to differentiate among them the results are consistent with the notion that preference uncertainty results in a hesitation to commit to any single action since small differences in attractiveness among the alternatives are potentially reversible consistent with this premise the effect of attractiveness difference on choice deferral decreased significantly when subjects were first allowed to practice making monetary trade offs among the available alternatives

the economics of the greenhouse effect the recognition that economic activity is contributing to climatic change with attendant costs that may be of large magnitudes has set in motion a substantial research effort this paper seeks to review the contribution of economics to analysis of the greenhouse effect and to the policies and instruments suggested as means of mitigating its damage a brief overview of the causes and consequences of global warming is given and a number of energy economy forecasting models are examined as the costs of global warming depend upon the extent to which preventative and adaptive measures are undertaken the techniques available to evaluate these costs are surveyed we examine extant targets for greenhouse gas emissions reduction and explore the frameworks within which optimal policy targets can be designed the paper also considers the narrower question of minimized abatement costs and surveys the types of models used to estimate them the merits of alternative policy instruments are examined paying particular attention to the role that risk and uncertainty and the costs of monitoring and implementation of policy under conditions of imperfect information may play in the choice of instruments problems of international co operation in the development of abatement policy are examined and we consider the compensations across both nations and generations that are likely to be necessary conditions for effective action

consumption self control by rationing purchase quantities of virtue and vice consumers attempts to control their unwanted consumption impulses influence many everyday purchases with broad implications for marketers pricing policies addressing theoreticians and practitioners alike this paper uses multiple empirical methods to show that consumers voluntarily and strategically ration their purchase quantities of goods that are likely to be consumed on impulse and that therefore may pose self control problems for example many regular smokers buy their cigarettes by the pack although they could easily afford to buy 10 pack cartons these smokers knowingly forgo sizable per unit savings from quantity discounts which they could realize if they bought cartons by rationing their purchase quantities they also self impose additional transactions costs on marginal consumption which makes excessive smoking overly difficult and costly such strategic self imposition of constraints is intuitively appealing yet theoretically problematic the marketing literature lacks operationalizations and empirical tests of such consumption self control strategies and of their managerial implications this paper provides experimental evidence of the operation of consumer self control and empirically illustrates its direct implications for the pricing of consumer goods moreover the paper develops a conceptual framework for the design of empirical tests of such self imposed constraints on consumption in consumer goods markets within matched pairs of products we distinguish relative virtue and vice goods whose preference ordering changes with whet her consumers evaluate immediate or delayed consumption consequences for example ignoring long term health effects many smokers prefer regular relative vice to light relative virtue cigarettes because they prefer the taste of the former however ignoring these short term taste differences the same smokers prefer light to regular cigarettes when they consider the long term health effects of smoking these preference orders can lead to dynamically inconsistent consumption choices by consumers whose tradeoffs between the immediate and delayed consequences of consumption depend on the time lag between purchase and consumption this creates a potential self control problem because these consumers will be tempted to over consume the vices they have in stock at home purchase quantity rationing helps them solve the self control problem by limiting their stock and hence their consumption opportunities such rationing implies that per purchase occasion vice consumers will be less likely than virtue consumers to buy larger quantities in response to unit price reductions such as quantity discounts we first test this prediction in two laboratory experiments we then examine the external validity of the results at the retail level with a field survey of quantity discounts and with a scanner data analysis of chain wide store level demand across a variety of different pairs of matched vice regular and virtue reduced fat calorie or caffeine etc product categories the analyses of these experimental field and scanner data provide strong convergent evidence of a characteristic crossover in demand schedules for relative vices and virtues for categories as diverse as among others potato chips chocolate chip cookies cream cheese beer soft drinks ice cream and frozen yogurt chewing gum coffee and beef andturkey bologna vice consumers demand increases less in response to price reductions than virtue consumers demand although their preferences are not generally weaker for vices than for virtues constraints on vice purchases are self imposed and strategic rather than driven by simple preferences we suggest that rationing their vice inventories at the point of purchase allows consumers to limit subsequent consumption as a result of purchase quantity rationing however vice buyers forgo savings from price reductions through quantity discounts effectively paying price premiums for the opportunity to engage in self control thus purchase quantity rationing vice consumers are relatively price in sensitive from a managerial and public policy perspective our findings should offer marketing practitioners in many consumer goods industries new opportunities to increase profits through segmentation and price discrimination based on consumer self control they can charge premium prices for small sizes of vices relative to the corresponding quantity discounts for virtues virtue consumers on the other hand will buy larger amounts even when quantity discounts are relatively shallow a key conceptual contribution of this paper lies in showing how marketing researchers can investigate a whole class of strategic self constraining consumer behaviors empirically moreover this research is the first to extend previous theoretical work on impulse control by empirically demonstrating its broader implications for marketing decision making

the rhetorics of ecological economics since the early 1980s there has been a lively discussion about the rhetoric of economics ecological economists however so far have not tried to incorporate this discussion into their work this paper is a first step towards including the discourse on rhetoric into the self awareness of ecological economics after a brief outline of what this discourse is about the importance of metaphors as one aspect of rhetoric is examined connections of the rhetorical discourse to ecological economics as a post normal science are shown it is argued that two rhetorics of ecological economics can be distinguished internal and external rhetoric while the former refers mostly to methodological issues the latter is of particular importance for the political impact that ecological economics can have finally some suggestions for research are made

consumption government spending and the real exchange rate using panel structural var analysis and quarterly data from four industrialized countries we document that an increase in government purchases raises output and private consumption deteriorates the trade balance and depreciates the real exchange rate this pattern of comovement poses a puzzle for both neoclassical and keynesian models an explanation based on the deep habit mechanism is proposed an estimated two country model with deep habits is shown to replicate well the observed responses of output consumption and the trade balance and the initial response of the real exchange rate to an estimated government spending shock

order in product customization decisions evidence from field experiments differentiated product models are predicated on the belief that a product s utility can be derived from the summation of utilities for its individual attributes in one framed field experiment and two natural field experiments we test this assumption by experimentally manipulating the order of attribute presentation in the product customization process of custom made suits and automobiles we find that order affects the design of a suit that people configure and the design and price of a car that people purchase by influencing the likelihood that they will accept the default option suggested by the firm

delaying the inevitable interest rate defense and balance of payments crises the classical model of balance of payments crises implicitly assumes that the central bank sits passively as international reserves dwindle in practice however central banks typically defend pegs aggressively by raising short term interest rates this paper analyzes the feasibility and optimality of raising interest rates to delay a potential bop crisis interest rate policy works through two distinct channels by raising demand for domestic interest bearing liquid assets higher interest rates tend to delay the crisis higher interest rates however increase public debt service and imply higher future inflation which tends to bring forward the crisis we show that under certain conditions it is feasible to delay the crisis but raising interest rates beyond a certain point may actually hasten the crisis a similar nonmonotonic relationship emerges between welfare and the increase in interest rates it is thus optimal to engage in some active interest rate defense but only up to a certain point i

a monetary explanation of the equity premium term premium and risk free rate puzzles this paper develops and estimates a monetary model that offers an explanation of some puzzling features of observed returns on equities and default free bonds the key feature of the model is that some assets other than money play a special role in facilitating transactions which affects the rate of return that they offer the model is capable of producing a low risk free rate a high equity premium and an average positive relationship between maturity and term premium for default free bonds the model s implications for the joint distribution of asset returns velocity inflation money growth and consumption growth are also compared to the behavior of these variables in the u s economy

a liquidity based resolution of the uncovered interest parity puzzle a new monetary theory is set out to resolve the uncovered interest parity puzzle uip puzzle it explores the possibility that liquidity properties of money and nominal bonds can account for the puzzle a key concept in our model is that nominal bonds carry liquidity premium due to their medium of exchange role as either collateral or means of payment in this framework no arbitrage condition ensures a positive comovement of real return on money and nominal bonds thus when inflation in one country becomes relatively lower i e real return on this currency is relatively higher its nominal bonds should also yield higher real return we show that their nominal returns can also become higher under the economic environment where collateral pledgeability and or liquidity of nominal bonds and or collateralized credit based transactions are relatively bigger since a currency with lower inflation is expected to appreciate the high interest currency does indeed appreciate in this case i e the uip puzzle is no longer an anomaly in our model our liquidity based theory in fact has interesting implications on many empirical observations that risk based explanations find difficult to reconcile with

a sketch of the economics of the greenhouse effect over the last decade scientists have studied extensively the greenhouse effect which holds that the accumulation of carbon dioxide co2 and other greenhouse gases ghgs is expected to produce global warming and other significant climatic changes over the next century see stephen schneider 1989 the present study presents an economic approach for analyzing policies to slow climate change

anomalies foreign exchange most all behavior can be explained by assuming that agents have stable well defined preferences and make rational choices consistent with those preferences in markets that eventually clear an empirical result qualifies as an anomaly if it is difficult to rationalize or if implausible assumptions are necessary to explain it within the paradigm this column will present a series of such anomalies readers are invited to suggest topics for future columns by sending a note with some reference to or better yet copies of the relevant research comments on anomalies printed here are also welcome the address

characterizing the financial cycle evidence from a frequency domain analysis a growing body of literature argues that the financial cycle is considerably longer in duration and larger in amplitude than the business cycle and that its distinguishing features became more pronounced over time this paper proposes an empirical approach suitable to test these hypotheses we parametrically estimate the whole spectrum of financial and real variables to obtain a complete picture of their cyclical properties we provide strong statistical evidence for the us and slightly weaker evidence for the uk validating the hypothesized features of the financial cycle in germany however the financial cycle is if at all much less visible

self control for the righteous toward a theory of precommitment to indulgence prior research has examined consumers use of self control to avoid hedonic myopic temptations such as overspending and smoking in this research we investigate the opposite form of self control whereby consumers force themselves to indulge and avoid default forms of spending on utilitarian necessities and or savings in particular consumers who have difficulty choosing items that are perceived as indulgences or luxuries e g a cruise over necessities e g saving for college education and cash in everyday decisions may use precommitments to indulgence especially when the psychological cost of such commitments is less concrete these propositions were tested in a series of studies involving real and hypothetical choices as well as process measures the results indicate that a substantial segment of consumers choose hedonic luxury rewards over cash of equal or greater value consumers typically explain such choices based on the need to precommit to indulgence to make sure that the award does no

monetary policy and exchange rate overshooting dornbusch was right after all abstract dornbusch s exchange rate overshooting hypothesis is a central building block in international macroeconomics yet empirical studies of monetary policy have typically found exchange rate effects that are inconsistent with overshooting this puzzling result has been viewed by some researchers as a stylized fact to be reckoned with in policy modelling however many of these studies in particular those using vector autoregressive vars approaches have disregarded the strong contemporaneous interaction between monetary policy and exchange rate movements by placing zero restrictions on them in contrast we achieve identification by imposing a long run neutrality restriction on the real exchange rate thereby allowing for contemporaneous interaction between the interest rate and the exchange rate in a study of four open economies we find that the puzzles disappear in particular a contractionary monetary policy shock has a strong effect on the exchange rate which appreciates on impact the maximum effect occurs within 1 2 quarters and the exchange rate thereafter gradually depreciates to baseline consistent with the dornbusch overshooting hypothesis and with few exceptions consistent with uncovered interest parity uip

a monetary analysis of balance sheet policies we augment a standard macroeconomic model to analyse the effects and limitations of balance sheet policies we show that the central bank can stimulate real activity by changing the size or the composition of its balance sheet when interest rate policy is ineffective specifically the central bank can stabilise the economy by increasing money supply against eligible assets even when the policy rate is at the zero lower bound by changing the composition of its balance sheet it can affect interest rates and for example neutralise increases in firms borrowing costs which is not possible under a single instrument regime we further analyse the limitations of balance sheet policies and show that they are particularly useful under liquidity demand shocks

the red and the black mental accounting of savings and debt in the standard economic account of consumer behavior the cost of a purchase takes the form of a reduction in future utility when expenditures that otherwise could have been made are forgone the reality of consumer hedonics is different when people make purchases they often experience an immediate pain of paying which can undermine the pleasure derived from consumption the ticking of the taxi meter for example reduces one s pleasure from the ride we propose a double entry mental accounting theory that describes the nature of these reciprocal interactions between the pleasure of consumption and the pain of paying and draws out their implications for consumer behavior and hedonics a central assumption of the model which we call prospective accounting is that consumption that has already been paid for can be enjoyed as if it were free and that the pain associated with payments made prior to consumption but not after is buffered by thoughts of the benefits that the payments will finance another important concept is coupling which refers to the degree to which consumption calls to mind thoughts of payment and vice versa some financing methods such as credit cards tend to weaken coupling whereas others such as cash payment produce tight coupling our model makes a variety of predictions that are at variance with economic formulations contrary to the standard prediction that people will finance purchases to minimize the present value of payments our model predicts strong debt aversion that they should prefer to prepay for consumption or to get paid for work after it is performed such pay before sequences confer hedonic benefits because consumption can be enjoyed without thinking about the need to pay for it in the future likewise when paying beforehand the pain of paying is mitigated by thoughts of future consumption benefits contrary to the economic prediction that consumers should prefer to pay at the margin for what they consume our model predicts that consumers will find it less painful to pay for and hence will prefer flat rate pricing schemes such as unlimited internet access at a fixed monthly price even if it involves paying more for the same usage other predictions concern spending patterns with cash charge or credit cards and preferences for the earmarking of purchases we test these predictions in a series of surveys and in a conjoint like analysis that pitted our double entry mental accounting model against a standard discounting formulation and another benchmark that did not incorporate hedonic interactions between consumption and payments our model provides a better fit of the data for 60 of the subjects the discounting formulation provides a better fit for only 29 of the subjects even when allowing for positive and negative discount rates the pain of paying we argue plays an important role in consumer self regulation but is hedonically costly from a hedonic perspective the ideal situation is one in which payments are tightly coupled to consumption so that paying evokes thoughts about the benefits being financed but consumption is decoupled from payments so that consumption does not evoke thoughts about payment from an efficiency perspective however it is important for consumers to be aware of what they are paying for consumption this creates a tension between hedonic efficiency and what we call decision efficiency various institutional arrangements such as financing of public parks through taxes or usage fees play into this tradeoff a producer developing a pricing structure for their product or service should be aware of these two conflicting objectives and should try to devise a structure that reconciles them

key currency status an exorbitant privilege and an extraordinary risk abstract what are the costs and benefits of the dollar s status as the key currency in the international monetary system here we present a calibrated two country model in which all exports are invoiced in the key currency and government bonds denominated in the key currency are held internationally to facilitate trade and as official reserve assets we show that the exorbitant privilege accruing to the key currency country comes from three sources 1 a bond seigniorage that we estimate to be worth about a half a percent of consumption per period to the united states 2 asymmetric responses to exogenous shocks that are worth an additional quarter of a percent of consumption per period and 3 a macroeconomic hegemony in monetary and fiscal policy reflecting the fact that the key currency s policy instruments are more potent but there is also an exorbitant risk to being the key currency country we show that the costs of a potential dumping of key currency bonds are also substantial moreover there appear to be no obvious monetary or fiscal policy responses that would lower the costs significantly

debt nonneutrality policy interactions and macroeconomic stability we study the consequences of non neutrality of government debt for macroeconomic stabilization policy in an environment where prices are sticky assuming transaction services of government bonds ricardian equivalence fails because public debt has a negative impact on its marginal rate of return and thus on private savings stability of equilibrium sequences requires a stationary evolution of real public debt which steers inflation expectations and rules out endogenous fluctuations under anti inflationary monetary policy regimes macroeconomic fluctuations tend to decrease with the share of tax financing which justifies tight debt constraints in particular a balanced budget policy stabilizes the economy under cost push shocks such that output and inflation variances can be lower than in a corresponding case where debt is neutral

expectations and the treasury bill federal funds rate spread over recent monetary policy regimes this paper shows that the spread between the 3 month treasury bill and the federal funds rate has significant predictive power for the future change in the federal funds rate during the volatile nonborrowed reserves operating regime but it has less and no predictive power during the borrowed reserves regime and the federal funds targeting regime respectively these findings suggest that treasury bill rates forecast future federal funds rates most accurately when the federal reserve follows a well defined rule that does not smooth the impact of shocks on the federal funds rate

liquidity premia and interest rate parity abstract due to the us dollar s dominant role for international trade and finance risk free assets denominated in us currency not only offer a pecuniary return but also provide transaction services both nationally and internationally accordingly the responses of bilateral us dollar exchange rates to interest rate shocks should differ substantially with respect to the us or foreign origin of the shock we demonstrate this empirically and apply a model of liquidity premia on us treasuries originating from monetary policy implementation the liquidity premium leads to a modification of uncovered interest rate parity uip which enables the model to explain an appreciation of the dollar subsequent to an increase in us interest rates if foreign interest rates follow the us monetary policy rate

the influence of consumer distractions on the effectiveness of food sampling programs abstract sampling programs are a significant element of the promotions mix particularly in the food category in this research the authors find that the degree to which consumers are distracted while sampling a product can influence the effectiveness of such programs in particular the authors find that distraction actually increases subsequent choice of the sampled food a finding that is contrary to what industry experts predict the authors propose a dual process model of somatosensory experiences to account for the findings in line with the model the findings suggest that the ultimate pleasure that a consumer derives from the taste of a food sample depends on two components an informational component and an affective component furthermore the findings suggest that distraction affects the subsequent choice of the sampled item by increasing decreasing the impact of the affective component informational component on subsequent choice
