the morning after explaining the slowdown in japanese growth in the 1990s abstract this paper uses a var to investigate four possible explanations of the extended slump in japanese economic activity over the 1990s the absence of bold and consistent fiscal stimulus the limited room for expansionary monetary policy due to a liquidity trap overinvestment and debt overhang and disruption of financial intermediation the results indicate that all of these factors played a role but that the major explanation is disruption in financial intermediation largely operating through the impact of changes in domestic asset prices on bank lending

skill biased technological change and rising wage inequality some problems and puzzles the recent rise in wage inequality is usually attributed to skill biased technical change sbtc associated with new computer technologies we review the evidence for this hypothesis focusing on the implications of sbtc for overall wage inequality and for changes in wage differentials between groups a key problem for the sbtc hypothesis is that wage inequality stabilized in the 1990s despite continuing advances in computer technology sbtc also fails to explain the evolution of other dimensions of wage inequality including the gender and racial wage gaps and the age gradient in the return to education

limited rationality and strategic interaction the impact of the strategic environment on nominal inertia much evidence suggests that people are heterogeneous with regard to their abilities to make rational forward looking decisions this raises the question as to when the rational types are decisive for aggregate outcomes and when the boundedly rational types shape aggregate results we examine this question in the context of a long standing and important economic problem the adjustment of nominal prices after an anticipated monetary shock our experiments suggest that two types of bounded rationality money illusion and anchoring are important behavioral forces behind nominal inertia however depending on the strategic environment bounded rationality has vastly different effects on aggregate price adjustment if agents actions are strategic substitutes adjustment to the new equilibrium is extremely quick whereas under strategic complementarity adjustment is both very slow and associated with relatively large real effects this adjustment difference is driven by price expectations which are very flexible and forward looking under substitutability but adaptive and sticky under complementarity moreover subjects expectations are also considerably more rational under substitutability

the medicaid notch labor supply and welfare participation evidence from eligibility expansions i assess the impact of losing public health insurance on labor market decisions of women by examining a series of medicaid eligibility expansions targeted toward young children these targeted expansions severed the historical tie between afdc and medicaid eligibility the reforms allowed a mother s earnings to increase without losing public health insurance for her young children increasing the income limit for medicaid resulted in a decrease in afdc participation and an increase in labor force participation among these women the effects were large for ever married women and negligible for never married women

more on tax perception and labour supply the spanish case abstract we estimate the marginal tax rate perceived by married spanish males the results suggest the existence of prominent divergences between subjective perception and formal income tax rules the efficiency and welfare implications of this tax rate gap are also assessed

immigration and prices this paper examines the behavior of prices following the unexpected arrival of a large number of immigrants from the former soviet union fsu to israel during 1990 i use store level price data on 915 consumer price index products to show that the increase in aggregate demand prompted by the arrival of the fsu immigration significantly reduced prices during 1990 when one controls for native population size and city and month effects a one percentage point increase in the ratio of immigrants to natives in a city decreases prices by 0 5 percentage point on average it is argued that this negative immigration effect is consistent with fsu immigrants the new consumers having higher price elasticities and lower search costs than the native population thus immigration can have a moderating effect on inflation through its direct effect on product markets and not only by increasing the supply of labor

the elasticity of substitution between time and market goods evidence from the great recession we document a change in household shopping behavior during the great recession households purchased more on sale larger sizes and generic products and increased coupon usage and shopping at discount stores we estimate a decline in returns to shopping during the recession therefore the increase in shopping behavior implies a significant decrease in households opportunity cost of time using the estimated cost of time and time use data we estimate a high elasticity of substitution between market expenditure and time spent on nonmarket work we find that households smooth a sizable fraction of consumption by varying their time allocation during recessions

tax aversion in labor supply abstract in a real effort laboratory experiment labor supply decreases more with the introduction of a tax than with a financially equivalent drop in wages this tax aversion is large in magnitude when we decompose the productivity decrease that arises from taxation we estimate that 40 is due to the lower net wage and the remaining 60 to tax aversion this tax aversion affects labor supply more on the extensive margin working less than on the intensive margin being less productive while working the aversion is equally strong whether tax revenue goes to the u s government or back to the experimenter a laboratory tax we discuss the implications of our results for the relationship between labor supply and taxation

complementarities of innovation activities an empirical analysis of the german manufacturing sector abstract innovation strategies in manufacturing often involve internal rd it is based on data from the german part of the community innovation survey cis 3 the results provide evidence for significant complementarities between internal r d and r d cooperation but cast doubt on the complementarity of internal and contracted r d since a productivity effect on firms patenting probability or sales with new products cannot be found

informational rigidities and the stickiness of temporary sales abstract how do retailers react to cost changes while temporary sales account for 95 of price change in our data retail prices respond to a wholesale cost increase entirely through the regular price sales actually respond temporarily in the opposite direction from regular prices as though to conceal the price hike additional evidence from responses to commodity cost and local unemployment shocks as well as broader evidence from bls data reinforces these findings institutional evidence indicates that sales are complex contingent contracts determined substantially in advance in a standard price discrimination model these institutional practices leave little money on the table

micro and macro elasticities in a life cycle model with taxes we build a life cycle model of labor supply that incorporates changes along both the intensive and extensive margin and use it to assess the consequences of changes in tax and transfer policies on equilibrium hours of work we find that changes in taxes have large aggregate effects on hours of work moreover we find that there is no inconsistency between this result and the empirical finding of small labor elasticities for prime age workers in our model micro and macro elasticities are effectively unrelated our model is also consistent with other cross country patterns

bounds on elasticities with optimization frictions a synthesis of micro and macro evidence on labor supply how can price elasticities be identified when agents face optimization frictions such as adjustment costs or inattention i derive bounds on structural price elasticities that are a function of the observed effect of a price change on demand the size of the price change and the degree of frictions the degree of frictions is measured by the utility losses agents tolerate to deviate from the frictionless optimum the bounds imply that frictions affect intensive margin elasticities much more than extensive margin elasticities i apply these bounds to the literature on labor supply the utility costs of ignoring the tax changes used to identify intensive margin labor supply elasticities are typically less than 1 of earnings as a result small frictions can explain the differences between micro and macro elasticities extensive and intensive margin elasticities and other disparate findings pooling estimates from existing studies i estimate a hicksian labor supply elasticity of 0 33 on the intensive margin and 0 25 on the extensive margin after accounting for frictions

modelling r d expenditure data with zero observations two equation model this article attempts to analyse the determinants of firms research and development r d expenditures in korea by considering the business environment after the economic crisis in 1997 in addition to take into account zero r d expenditure this article employed a two equation model unlike models used in other studies this method incorporates a two level decision structure the participation decision and the decision on the amount to spend once the issue of participation has been decided according to the estimation results while the proposition that larger firms are more active in r d is true the proposition that firms that possess market power are more active in r d is not true for korea technical cooperation among korean firms seems to be less active than in other countries in addition the results indicate that foreign investment stimulates the firms r d expenditure furthermore a number of factors were found to play a role in promoting firms r d activities the external conditions of the f

firm size and r d intensity a re examination using data from the federal trade commission s line of business program and survey measures of technological opportunity and appropriability conditions this paper finds that overall firm size has a very small statistically insignificant effect on business unit r d intensity when either fixed industry effects or measured industry characteristics are taken into account business unit size has no effect on the r d intensity of business units that perform r d but it affects the probability of conducting r d business unit and firm size jointly explain less than one per cent of the variance in r d industry effects explain nearly half the variance two sets of well known hypotheses are associated with the later work of joseph schumpeter the first concerns the effects of market concentration on research and development investment and on innovative performance the second bears on the effects of firm size on r d and innovation in a recent paper levin cohen and mowery 1985 we re examined the first set of hypotheses simple regressions at the line of business level replicated the established findings that both r d intensity and innovative performance first increase and then decrease as industrial concentration rises the effect of concentration however was sharply attenuated when we controlled for interindustry differences in technological opportunity and in the appropriability of returns from new technology our results suggested that it is probably unwarranted to conclude that market concentration favors r d investment and innovation in this paper we investigate the schumpeterian hypothesis that large size is conducive to r d investment this relationship has been studied at least as intensively as the link between concentration and r d but our approach is novel in two respects first using data collected by the federal trade

are income and consumption taxes ever really equivalent evidence from a real effort experiment with real goods abstract the public finance literature demonstrates the equivalence between consumption and labor income wage taxes we introduce an experimental paradigm in which individuals make real labor leisure choices and spend their earned income on real goods we use this paradigm to test whether a labor income tax and an equivalent consumption tax lead to identical labor leisure allocations despite controlling for subjects work ability and inherent labor leisure preferences and disallowing saving subjects reduce their labor supply significantly more in response to an income tax than to an equivalent consumption tax we discuss the economic implications of a policy shift to a consumption tax

iceland s natural experiment in supply side economics the move to a pay as you earn income tax system in iceland in 1987 1988 made income earned in 1987 tax free using a sample of 9 274 individuals for the years 1986 1987 and 1988 we calculate the labour supply response of this change and find that total labour supply rose by 6 7 in 1987 over the average of 1986 and 1988 when we correct for entry in 1988 this consists of an 8 6 increase in weeks supplied by those already in the labour market in 1986 and a 1 9 decline due to entry exit the elasticity of weeks worked to the rise in after tax wages was 0 41 for men and 0 11 for women while the participation rate of women increased somewhat in our sample participation by men fell this abstract was borrowed from another version of this item

consumer durables and inertial behaviour estimation and aggregation of s s rules for automobile purchases the s s model originally introduced in the study of inventories see arrow et al 1951 scarf 1959 has recently received renewed attention both in the durable consumption and in the investment and labour demand literatures caballero 1993 for instance appeals to these type of models to explain the time series properties of durable expenditure and in particular the persistence or slow adjustment of such a variable in this paper i model the purchase behaviour of automobiles by u s households as an s s rule i estimate a flexible specification of such a rule using a large microeconomic data set and study some of the aggregate implications of this type of inertial behaviour the paper is one of the first attempts at estimating directly the parameters of an s s rule using micro data because of this some of the methodological issues concerning the specification and the estimation of s s rules are relevant for many potential applications furthermore the paper is one of the first to discuss and quantify the aggregate implications of an s s rule estimated on micro data in the presence of non convex transaction costs a full and consistent characterization of individual behaviour is very hard and typically requires strong restrictions grossman and laroque 1991 prove that an s s rule is optimal for a consumption and investment problem under very special circumstances some of their results were extended by eberly 1991 and beaulieu 1993a b eberly 1991 in particular has derived some closed form solutions for durable consumption in the presence of transaction costs while caballero and engel 1994 construct a model of investment where an s s rule is optimal the main problem with these theoretical results is that it is only possible to show optimality of s s rules under very stringent conditions in particular a necessary condition to derive them is that the optimization problem faced by an individual consumer can be reduced to a problem with a single state variable unfortunately as pointed out by bar ilan and blinder 1992 even simple generalizations are extremely difficult to analyse

zombie lending and depressed restructuring in japan this paper explores the role that misdirected bank lending played in prolonging the japanese macroeconomic stagnation that began in the early 1990s the investigation focuses on the wide spread practice of japanese banks of continuing to lend to otherwise insolvent firms we docu ment the prevalence of this forbearance lending and show its distorting effects on healthy firms that were competing with the impaired firms the paper by hoshi 2000 was the first to call attention to this phenomenon and its ramifi

inflation price competition and consumer search technology abstract this paper studies an s s pricing model in the presence of inflation and price competition in search markets i present a model in which consumers search technologies can influence firms price setting price dispersion and the market structure the result obtained shows that although price competition among firms is intensified in markets where consumers search technologies are more efficient price inflation is counter intuitively more likely to increase the monopoly power and stimulate entry of firms in these markets the model also provides new empirical implications for firms price setting behaviors

charity donations and the euro introduction some quasi experimental evidence on money illusion we compare the revenues of a house to house collection for a charity before and after the introduction of the euro in a ceteris paribus setting we find strong evidence of money illusion supplementing earlier econometric experimental and survey evidence on its existence

working less and bargain hunting more macro implications of sales during japan s lost decades standard new keynesian models have often neglected temporary sales in this paper we ask whether this treatment is appropriate in the empirical part of the paper we provide evidence using japanese scanner data covering the last two decades that the frequency of sales was closely related with macroeconomic developments specifically we find that the frequency of sales and hours worked move in opposite directions in response to technology shocks producing a negative correlation between the two we then construct a dynamic stochastic general equilibrium model that takes households decisions regarding their allocation of time for work leisure and bargain hunting into account using this model we show that the rise in the frequency of sales which is observed in the data can be accounted for by the decline in hours worked during japan s lost decades we also find that the real effect of monetary policy shocks weakens by around 40 due to the presence of temporary sales but monetary policy still matters

the effect of taxes on male and female labor supply in sweden this paper estimates labor supply functions for married men and women in sweden using data from 1980 taking account of the complete form of individuals budget constraints both linear and quadratic supply functions are estimated with and without random preferences a novel feature is that for women the wage rate and labor supply functions are estimated simultaneously using a full information maximum likelihood method this method yields substantially larger wage and income elasticities than does the previously used two step methods another result is that the quadratic supply function wage elasticities for men and women are virtually the same if the elasticities are evaluated at the same net wage rate and hours of work for men and women the estimated functions are used to calculate the effect of tax reforms

what has been learned about labor supply in the past twenty years the main advance in the study of labor supply in the past 20 years has come in recognizing and interpreting the variety of different labor supply functions that coexist in the empirical literature a crucial theoretical distinction with important empirical payoff is that between labor supply choices at the extensive margin i e labor force participation and employment choices and choices at the intensive margin i e choices about hours of work or weeks of work for workers another important distinction is the one between a descriptive labor supply function and a structural supply function that can be the basis for out of sample policy investigations concerning responses to tax and welfare programs and evaluations of welfare losses a full understanding of the participation hours dichotomy leads to an appreciation of the importance of the problem of selection bias what is the wage to impute to a nonworking person these distinctions are a legacy of the research conducted on labor supply over the past 20 years many important empirical questions have been addressed i how strong are the effects of taxes welfare and transfer programs on labor supply ii how important is intertemporal substitution can life cycle labor supply models explain business cycle labor supply behavior iii has the consensus view of the 1960 s of high labor supply elasticities for married women and low labor supply elasticities for married men held up all of the empirical evidence assembled on labor supply must be called into question in the light of important research on the basic quality of the data conducted by analysts at the university of michigan i discuss this evidence in a concluding section except for my discussion of measurement issues i focus only on the major discoveries about which a general consensus has emerged

life cycle prices and production we use scanner data and time diaries to document how households substitute time for money through shopping and home production we document substantial heterogeneity in prices paid for identical goods for the same area and time with older households shopping the most and paying the lowest prices doubling shopping frequency lowers a good s price by 7 to 10 percent we estimate the shopper s price of time and use this series to estimate an elasticity of substitution between time and goods in home production of roughly 1 8 the observed life cycle time allocation implies a consumption series that differs markedly from expenditures

sticky information and sticky prices abstract in the u s and europe prices change at least once a year yet nominal macro shocks seem to have real effects lasting well beyond a year sticky information models as posited by mankiw and reis 2002 sticky information versus sticky prices a proposal to replace the new keynesian phillips curve quarterly journal of economics 117 1295 1328 sims 2003 implications of rational inattention journal of monetary economics 50 3 665 690 and woodford 2003 princeton university press princeton nj can reconcile micro flexibility with macro rigidity we simulate a sticky information model in which price setters update information on macro shocks less frequently than information on micro shocks we then examine price changes in the micro data underlying the u s cpi empirical price changes react to old information just as sticky information models predict

micro and macro price dynamics in daily data abstract using japanese daily scanner data with three billion observations of prices and quantities from 1988 to 2005 this paper investigates micro and macro price dynamics these data reveal that the frequency of price changes is much larger than that found in standard monthly datasets the price change frequency exhibits a clear trend and strong across store heterogeneity which casts doubts on standard new keynesian assumptions the consumer price index cpi based on scanner data appears to track the official cpi relatively well except for a period in which the latter arguably had an upward bias

r d appropriability opportunity and market structure new evidence on some schumpeterian hypotheses one of the largest bodies of literature in the field of industrial organization is devoted to the interpretation and testing of several hypotheses advanced by joseph schumpeter 1950 concerning innovation and industrial market structure one set of hypotheses focuses on the role of firm size as a determinant of r d spending and the rate of technological advance another set focuses on the effect of market concentration on r d and technological advance in this paper we reexamine the latter set of hypotheses at the industry level using new data on r d appropriability and technological opportunity collected by levin et al 1984 in a survey of r d executives in 130 industries

sales and monetary policy this paper analyses the efiect of monetary policy in a model where sales occur in equilibrium some consumers are loyal to a particular brand of a good others are bargain hunters as a result producers flnd it optimal to sell their goods at a normal price through some retailers and at a sale price through others the margin of adjusting the amount sold on sale is potentially very important if producers can adjust the fraction sold on sale with sticky prices and wages money is approximately neutral if we ignore the reasons behind sales but that result changes dramatically when we consider that producers optimally choose to sell some of their goods on sale owing to strategic substitutabilities in the sales decision money has strong procyclical efiects

indivisible labor lotteries and equilibrium abstract this paper considers an economy where labor is indivisible and agents are identical although the discontinuity in labor supply at the individual level disappears as a result of aggregation it is shown that indivisible labor has strong consequences for the aggregate bahavior of the economy it is also shown that optimal allocations involve lotteries over employment and consumption

heterogeneity and aggregation implications for labor market fluctuations we demonstrate that aggregate employment and consumption can increase without a corresponding movement in productivity in a model with heterogeneous agents where the only aggregate disturbance is a productivity shock the interaction between incomplete capital markets and indivisible labor results in a low employment productivity correlation and creates a time varying wedge between the marginal rate of substitution for commodity consumption and hours and productivity our results caution against viewing the measured wedge as an inefficiency due to a failure of labor market clearing or as a fundamental driving force behind business cycles jel d31 e32 j22 j24 j31

the non equivalence of labour market taxes a real effort experiment under full rationality a labour market tax levied on employers and a corresponding income tax levied on employees are equivalent with boundedly rational agents this equivalence is no longer obvious in a real effort experiment we study the effects of these taxes on preferences concerning the size of the public sector subjective well being labour supply and on the job performance our findings suggest that employer side taxes induce preferences for a larger public sector subjective well being is higher under employer side taxes while labour supply is lower at least at the extensive margin we discuss three mechanisms that may underlie these results

on the optimal income taxation some further numerical results abstract using numerical calculations we show in the optimal income tax model that a realistic value for the elasticity of substitution between consumption and leisure 0 5 leads to conclusions different from some of those drawn by mirrlees 1971 and atkinson 1973 the marginal tax rates are not so low and the shape of the tax schedule is for a great majority of the population substantially nonlinear a new feature in our calculations is that both results come out without going to maximin as done by atkinson 1973 we study in special cases the locality of the zero limit of the marginal tax rate at the upper end of the ability distribution and we achieve a very definite conclusion this result is really very local we also present an interesting approximation result concerning the relationship between the level of the government revenue and the marginal tax rate for individuals with high ability an important methodological remark analogous to sen s critique on the ethical measures of inequality is made on the interpretation of optimal income tax calculations

determinants of innovation in energy intensive industry and implications for energy policy abstracts the korean government adopted green growth in 2008 as an environmentally friendly growth strategy the energy efficiency of korea however is still relatively low due to the large portion of energy intensive industry eii in its manufacturing sector to improve energy efficiency in korea from an eii perspective a new approach has to be taken because restructuring entire industries would take too much time and be too costly this study aims to emphasize the importance of innovation and analyze the effects of r d on product and process innovations in eii in korea the probit model is adopted to estimate the effects of eight determinants in the korea innovation survey 2008 data the results of this study demonstrate that one of the most important determinants the r d personnel ratio has a strong positive effect on both product and process innovation while another determinant r d intensity only has a strong and positive effect on process innovation in eii because of the resulting innovation energy policies should be enacted to enhance energy efficiency thus the korean government should keep providing incentives for firms in eii to invest more financial and human resources in their r d activities

wage subsidies and fair wages abstract wage subsidies can be provided directly to the worker or indirectly by subsidizing the employer with reduced cost of labor employers offer higher wages the standard literature stipulates that this statutory incidence bears no implications for the economic incidence we propose and test a mechanism by which indirect subsidies lead to higher social welfare studies show that workers reciprocate higher wages with higher effort indirect subsidies are shifted to the workers as higher wages leading workers to reciprocate with higher effort and productivity a controlled laboratory experiment supports our behavioral hypotheses and confirms the behavioral and welfare implications

gender disparity in angel financing this study uses unique hand collected data from a televised entrepreneurial pitch competition to examine gender differences in obtaining angel financing results indicate that while the yield rates between male and female teams do not differ a gender disparity in the amount of angel funding does in fact exist female teams receive less capital and provide more equity relative to their male counterparts even when controlling for typical determinants of investment such as industry and prior company success further we find that female teams receive investments with lower valuations than their male counterparts largely because they initially offer higher equity stakes for less capital thus this suggests that limitations to angel financing of female entrepreneurial ventures may be partly self imposed

the effects of housing assistance on labor supply evidence from a voucher lottery this study estimates the effects of means tested housing programs on labor supply using data from a randomized housing voucher wait list lottery in chicago economic theory is ambiguous about the expected sign of any labor supply response we find that among working age able bodied adults housing voucher use reduces labor force participation by around 4 percentage points 6 percent and quarterly earnings by 329 10 percent and increases temporary assistance for needy families program participation by around 2 percentage points 15 percent we find no evidence that the housing specific mechanisms hypothesized to promote work such as neighborhood quality or residential stability are important empirically jel i38 j22 r23 r38

determinants of innovation the study examines how firm size market structure profitability and growth influence innovative activity in small to medium sized australian manufacturing businesses using the recently released confidentialised unit record file drawn from the business longitudinal survey of the australian bureau of statistics regression analysis is conducted to determine the factors that effect subsequent innovative activity for the full sample of businesses as well as for sub samples of firms from high and low technological opportunity industries most variables including size r d intensity market structure and trade shares are found to be conducive to further innovative activity for the full sample and for high tech firms for low tech industries fewer variables are significant

euro illusion a natural experiment we collect and analyse data on church collections to assess whether the introduction of euro notes and coins had real effects on giving data for italy suggests that money is not completely neutral while irish data suggests a lower degree of money illusion a smaller data set from continental europe suggests different sorts of money illusion

estimating the perceived tax scale within a labor supply model the swedish marginal tax scale is too complex to be known in detail by individuals this paper indicates that perceived tax scales can be estimated jointly with a labor supply equation the differe

the elasticity of taxable income with respect to marginal tax rates a critical review this paper critically surveys the large and growing literature estimating the elasticity of taxable income with respect to marginal tax rates using tax return data first we provide a theoretical framework showing under what assumptions this elasticity can be used as a sufficient statistic for efficiency and optimal tax analysis we discuss what other parameters should be estimated when the elasticity is not a sufficient statistic second we discuss conceptually the key issues that arise in the empirical estimation of the elasticity of taxable income using the example of the 1993 top individual income tax rate increase in the united states to illustrate those issues third we provide a critical discussion of selected empirical analyses of the elasticity of taxable income in light of the theoretical and empirical framework we laid out finally we discuss avenues for future research jel h24 h31 j22

expected consumer s surplus and the welfare effects of price stabilization suppose a consumer faces a price which is uncertain ex ante a question which often arises is whether the consumer would benefit from a stabilization policy under which the price would then be fixed and known with certainty many authors have addressed this question by calculating the expected compensating variation of the price change others have used expected marshallian consumer s surplus often with the explanation that it is a good approximation to expected compensating variation 2 an important unresolved issue however is whether expected compensating variation does in fact provide a valid ranking of stochastic prices against stabilized prices i e a ranking in agreement with that given by expected utility in section 2 we demonstrate that expected compensating variation is not in general a valid utility indicator in essence while utility comparisons under uncertainty require the use of the cardinal properties of von neumannmorgenstern utility functions the expected surplus measures depend only on ordinal preference rankings expected compensating variation then is completely insensitive to and cannot reflect the precise factor of interest in suchstudies the consumer s attitudes toward risk we then derive a set of restrictions on the utility function which are necessary in order for expected compensating variation to be a valid measure we see that price stabilization policies can only be evaluated with compensating variation if consumer preferences are assumed to satisfy quite stringent requirements this is in constrast to the familiar certainty case in which compensating variation always provides correct rankings

five facts about prices a reevaluation of menu cost models are price decreases 3 the frequency of price increases covaries strongly with inflation whereas the frequency of price decreases and the size of price increases and price decreases do not 4 the frequency of price change is highly seasonal it is highest in the first quarter and then declines 5 we find no evidence of upwardsloping hazard functions of price changes for individual products we show that the first second and third facts are consistent with a benchmark menu cost model whereas the fourth and fifth facts are not

biased effects of taxes and subsidies on portfolio choices we study how taxes and subsidies affect portfolio choices in a laboratory experiment we find highly significant differences after intervention even though the net income is identical in all our treatments and thus the decision pattern of investors should be constant in particular we observe that the willingness to invest in the risky asset decreases markedly when an income tax has to be paid or when a subsidy is paid we investigate this result further in a range of variations of the baseline experiment and find our main result to be largely robust however as we reduce the number of states of nature the bias weakens considerably

prices are sticky after all abstract economists have interpreted the evidence that prices change every four months as implying that sticky prices cannot be important for monetary transmission theory implies that this interpretation is correct if most price changes are regular but not if a large fraction are temporary as in the data since regular prices are much stickier than temporary ones our models predict that the stickiness of the aggregate price level matches that in a standard calvo model or a standard menu cost model in which micro level prices change about once a year in this sense prices are sticky after all

behavioral effects of withholding taxes on labor supply in most advanced economies income tax collection uses third party withholding for wage income because withholding taxes do not necessarily reflect true effective taxes these may give false signals of net of tax pay we test labor supply responses to such misconceptions using laboratory experiments withholding taxes and the resulting tax refunds should be behaviorally neutral but our results show that tax adjustments lead to effort adjustments which suggests that withholding blurs tax incentives while there is no statistically significant response in the overall sample the participants in the subgroup who self assess to be motivated by monetary incentives about half of the total sample reduce their effort in response to withholding taxes and increase their effort after receiving tax refunds

the cyclicality of sales regular and effective prices business cycle and policy implications author s coibion olivier gorodnichenko yuriy hong gee hee abstract we study the cyclical properties of sales regular price changes and average prices paid by consumers effective prices using data on prices and quantities sold for numerous retailers across many us metropolitan areas inflation in the effective prices paid by consumers declines significantly with higher unemployment while little change occurs in the inflation rate of prices posted by retailers this difference reflects the reallocation of household expenditures across retailers a feature of the data which we document and quantify rather than sales we propose a simple model with household store switching and assess its implications for business cycles and policymakers jel d12 e31 e32 l25 l81

taxpayer confusion evidence from the child tax credit we develop an empirical test for whether households understand or misperceive their marginal tax rate our identifying variation comes from the loss of the child tax credit when a child turns 17 using this age discontinuity we find that despite this tax liability increase being lump sum and predictable households reduce their reported wage income upon discovering they have lost the credit this finding suggests that households misinterpret at least part of this tax liability change as an increase in their marginal tax rate this evidence supports the hypothesis that tax complexity can cause confusion and leads to unintended behavioral responses jel d12 d14 h24 h31

the effects of monetary policy in japan this article interprets time series facts regarding the sources of business fluctuations in japan and attempts to uncover possible characteristics of the effects of monetary policy over the last two decades it argues that given the institutional features of the bank of japan s operating procedures a simple recursive vector autoregressive var model that consists of interest rates money stock prices and output all in first differences may serve as a useful benchmark for japan the main finding is that monetary policy shocks in fact have a persistent effect on real output especially in the rise and fall of japan s bubble economy in the late 1980s

equilibrium price dispersion in retail markets for prescription drugs this study seeks to establish the empirical importance of price dispersion due to costly consumer search by examining retail prices for prescription drugs posted prices in two geographically distinct markets are shown to vary considerably across pharmacies within the same market even after one controls for variation due to pharmacy differences pharmacy heterogeneity accounts for at most one third of the observed price dispersion the empirical analysis hinges on the observation that consumers incentives to price shop depend on characteristics of the drug therapy cross sectional patterns in price distributions across drugs are consistent with the predictions of a search model prices for repeatedly purchased prescriptions for which the expected benefits of search are highest exhibit significant reductions in both dispersion and price cost margins

progressive taxation in a tournament economy abstract not enough is known about the responsiveness of individuals in particular those who work under different incentives to changes in marginal tax rates we ask whether changes in tax rates are less distortionary for workers engaged in a contest to examine this potential rationale for a more progressive tax code we first model the effort decisions of workers faced with progressive taxation under tournaments and piece rates because of the difficulty identifying any distortion that may be induced by the tax code in naturally occurring data we then report on the results of a real effort experiment based on this model consistent with a behavioral approach to public finance we find that competitive tournament workers are less sensitive and hint in our discussion at the possible welfare benefits of progressive taxation in tournament economies

experimental evidence on the relationship between tax evasion opportunities and labor supply abstract motivated by the observation that access to evasion opportunities is distributed heterogeneously across the labor market this paper examines the extent to which labor supply elasticities with respect to tax rates depend on such evasion opportunities we first discuss the channels through which access to evasion affects labor supply responses and then set up a laboratory experiment n 205 in which all participants undertake a real effort task over several rounds subjects face a tax rate that varies across rounds and are required to pay taxes on earned income the treatment group is given the opportunity to underreport income while the control group is not we find evidence that participants in the treatment group respond differently to changes in the net of tax rate than participants in the control group the effect is more prevalent when tax rates fall additionally the direction of the treatment effect is dependent on the evolution of tax rates across rounds

why are products sold on sale explanations of pricing regularities this paper reports on interesting changes in markdown pricing practices over time and differences in the pricing within a product line the price discrimination and the uncertainty hypotheses appear to better explain the data than the peak load hypothesis fashion has become more important over time and appears to explain the greater seasonal variation in retail apparel prices in recent years differences in uncertainty also explains differences in the pricing of different types of men s dress shirts

to protect or not to protect modes of appropriability in the small enterprise sector abstract what appropriation strategies are chosen by innovative small firms a cluster analysis of data from the german cis was carried out to indentify four distinct modes of appropriability in the small enterprise sector the results show that for many innovative small firms the key question is not whether to use intellectual property rights iprs or not but whether to protect their innovations from imitation at all furthermore formal and informal innovation protection mechanisms should not be seen as mutually exclusive since several are employed jointly secrecy and lead time advantages over competitors are often combined with iprs yet a number of small firms use complexity of design as a substitute to patent protection the relevance of each appropriation mode depends on such factors as the degree of innovativeness the type of innovator and the general market environment which implies that the importance of iprs is limited to specific business contexts furthermore regarding firm performance as measured by innovation effects some evidence is found that choosing both ipr and non ipr oriented appropriation strategies can prove to be effective in achieving company goals taken all together the study implies that the use of iprs by innovative small firms is highly selective the paper concludes with a discussion of the implications for policy and research

adjustment costs firm responses and micro vs macro labor supply elasticities evidence from danish tax records we show that the effects of taxes on labor supply are shaped by interactions between adjustment costs for workers and hours constraints set by firms we develop a model in which firms post job offers characterized by an hours requirement and workers pay search costs to find jobs we present evidence supporting three predictions of this model by analyzing bunching at kinks using danish tax records first larger kinks generate larger taxable income elasticities second kinks that apply to a larger group of workers generate larger elasticities third the distribution of job offers is tailored to match workers aggregate tax preferences in equilibrium our results suggest that macro elasticities may be substantially larger than the estimates obtained using standard microeconometric methods

search price setting and inflation a model of monopolistic competition in an inflationary environment is developed which embodies optimal sequential search price dynamics and entry on the part of consumers and firms respectively equilibrium price strategies are s s these bounds increase continuously with consumer search costs and so does price dispersion indeed the whole equilibrium varies smoothly from the competitive bertrand to the monopolistic diamond 1971 end of the spectrum the latter s paradoxical result is explained as a limiting case where frictions on firms side of the market price adjustment costs but not on buyers search costs tend to zero a positive relationship between smooth and perfectly anticipated inflation and price dispersion or uncertainty is established

inherent inequality and the optimal graduation of marginal tax rates in most countries marginal tax rates increase with income this is at variance with the results of the optimal income taxation literature whose numerical calculations have established the presumption that optimal marginal tax rates should decline with income have the existing results of optimal income tax literature therefore established a presumption that the observed pattern is suboptimal the object of this paper is to attempt to answer this question the numerical calculations that followed mirrlees s 1971 pioneering contribution tried many variations on his basic parametrisation including different preference structures and different functional forms however so far as we are aware most of the reported results maintain his basic assumption of a log normal distribution of abilities or wages with a standard deviation of logs of 0 39 mirrlees 1971 himself appealed the work of lydall 1969 for this figure but it has become the industry standard we show in this paper that departures from this assumption in particular increases in inherent inequality can alter the qualitative pattern of optimal marginal tax rates dramatically contrary to the currently available calculations we show that the optimal graduation can indeed be such that marginal tax rates increase for the majority of the population which is consistent with the observed pattern but that there continues to exist a significant income range at the top where marginal tax rates decline which of course is counter to the observed pattern

reference prices costs and nominal rigidities we assess the importance of nominal rigidities using a new weekly scanner dataset we find that nominal rigidities take the form of inertia in reference prices and costst defined as the most common prices and costs within a given quarter reference prices are particularly inertial and have an average duration of roughly one year even though weekly prices change roughly once every two weeks we document the relation between prices and costs and find sharp evidence of state dependence in prices we use a simple model to argue that reference prices and costs are useful statistics for macroeconomic

tax misperceptions and the effect of informational tax nudges on retirement savings despite subjects being informed about tax rules before making saving decisions we find using laboratory experiments that deferred taxation results in after tax pensions that are approximately 25

identifying the determinants of the decision to create socially responsible funds an empirical investigation this paper proposes an empirical assessment of the main factors behind the decision of a corporate sponsor to launch a socially responsible sr fund our analysis is performed on a database that encompasses 414 sr fund creations by 46 corporate sponsors between 1990 and 2012 we provide evidence that economic and human resources slack leverage low media coverage and high extra financial performance of the corporate sponsor contribute to an increase of the probability to propose sr funds these results lead us to argue that the introduction of such funds goes beyond the economic objective of enlarging the market share of the corporate sponsor it may thus be seen as a particular strategy in terms of communication and signaling due to the specific characteristics of sr funds

innovation and productivity in developing countries a study of argentine manufacturing firms behavior 1992 2001 abstract following the methodology employed in studies for industrialized countries and using panel data from innovation surveys in argentina with information for 1992 2001 this paper contributes to the nascent literature that analyzes the determinants of innovative inputs and outputs and their impacts on manufacturing firms productivity in developing countries the econometric results show that in house r d and technology acquisition expenditures have positive payoffs in terms of enhanced probability of introducing new products and or processes to the market in turn innovators attain higher productivity levels than non innovators the results also show that large firms have a higher probability of engaging in innovation activities and of becoming innovators

how work effort responds to wage taxation an experimental test of a zero top marginal tax rate abstract phelps 1973 sadka 1976 seade 1977 presented theorems that showed work effort could increase if the marginal tax rate was zero at the top income this was tested in a laboratory experiment the prediction was supported

economic determinants of technological progress in g7 countries a re examination abstract this study examines the relationship between technological change and a series of key macroeconomic variables in g7 countries basically we find that the rate of interest has a negative impact on the pace of innovation while investments in the r d sector high technology exports as well as net fdi inflows enhance technological change the most surprising result of our analysis concerns the openness to trade ratio contrary to theoretical expectations and the findings of previous empirical studies we were unable to find a positive or negative significant relationship between openness to trade and the rate of innovation in this study

small menu costs and large business cycles a macroeconomic model of monopoly i introduction the conflict between modern neoclassical and traditional keynesian theories of the business cycle centers upon the pricing mechanism in neoclassical models prices are fully flexible they represent the continuous optimization of economic agents and the continuous intersection of supply and demand in keynesian models prices are often assumed to be sticky they do not necessarily equilibrate all markets at all times one of the reasons for the resurgence of the equilibrium approach to macroeconomics has been the absence of a theoretical underpinning for this keynesian price stickiness this note shows that sticky prices can be both privately efficient and socially inefficient the business cycle results from the suboptimal adjustment of prices in response to a demand shock to the extent that policy can stabilize aggregate demand it can mitigate the social loss due to this suboptimal adjustment in some keynesian models prices are simply exogenously fixed 2 in others agents must set their prices in advance of the transaction date the act of altering a posted price is certainly costly these costs include such items as printing new catalogs and informing salesmen of the new price yet these menu costs are small and therefore generally perceived as providing only a weak foundation for these fixed price models however this inference is flawed small menu costs can cause large welfare losses the claim that price adjustment costs are small does not rebut the claim that they are central to understanding economic fluctuations

net wage illusion in a real effort experiment in a controlled laboratory experiment subjects had to fold letters in order to earn money while the net income per letter was the same in the three treatments the gross income varied and the tax rate was 0 25 and 50 percent although work incentives should be the same in all treatments subjects worked harder and longer when they were taxed we conclude that this is because of a net wage illusion effect the existence of this effect demonstrates that not only are the tax rate and the tax base of importance for work incentives but the perception of a tax is also important

group characteristics evolution arising from asymmetric information in asymmetric information problems agents with less information principals or contractors usually take as given the preferences of agents with more information agents or contractees moreover the distribution of characteristics of contractees is supposed to be invariant in this article we consider a mixed framework of asymmetric information adverse selection followed by moral hazard where those two assumptions are excluded specifically the contractor only knows the current distribution of characteristics and the contractees may change them after signing the contract if this improves their welfare thus we find that the asymmetric information problem leads to a group eect changes of characteristics this feedback defines a sequence of temporary equilibria we provide conditions for the convergence of that sequence to a stationary long run equilibrium we also prove that both temporary equilibrium and long run equilibrium coincide with the equilibrium in classical models of adverse selection and the moral hazard problem vanishes in the long run

adjustment of consumers durables stocks evidence from automobile purchases this paper tests an optimal s s rule in household durable purchases and examines directly the resulting aggregate expenditure dynamics the observed decision rule responds to income uncertainty and growth as predicted by an s s model resulting from transactions costs tests against liquidity constraints find that about half the households purchase according to an optimal s s rule aggregating the s s rule over households produces a cross section distribution of durables holdings the empirical distribution is similar to that predicted theoretically as is its response to aggregate shocks furthermore simulations of aggregate expenditure based on the household distribution exhibit dynamics consistent with those observed in the 1980s

implications of rational inattention abstract a constraint that actions can depend on observations only through a communication channel with finite shannon capacity is shown to be able to play a role very similar to that of a signal extraction problem or an adjustment cost in standard control problems the resulting theory looks enough like familiar dynamic rational expectations theories to suggest that it might be useful and practical while the implications for policy are different enough to be interesting

how work effort responds to wage taxation a non linear versus a linear tax experiment abstract this is one of a series of experiments by the author testing predictions of the labor supply model that comes from the theory of single period single person utility maximization where utility is a quasi concave function of consumption and leisure and where consumption is assumed a normal good this paper studies how people adjust their work effort in response to a gross wage rate change under a non linear tax system in comparison to a linear tax system the linear tax system is chosen as the hausman equivalent of the non linear system at the starting wage rate the prediction is that work effort will be higher under the linear tax system after the gross wage rate change this experiment supports the theorem the implication is that tax flattening will yield more labor and possibly more tax revenues as wage rates rise
