evaluating welfare reform in the united states this paper reviews the economic literature on welfare reform over the 1990s a brief summary of the policy changes is followed by a discussion of the methodological techniques that analyze the effects of these changes on outcomes the paper then critically reviews the econometric and experimental literature on caseload changes labor force changes poverty and income changes and family formation changes a growing body of evidence suggests that recent policy changes have influenced economic behavior and well being one particular set of new style welfare programs seems to show especially promising results with significantly increased work and earnings and reduced poverty

real exchange rate dynamics with nominal parities structural change and overshooting abstract the relationship between structural changes that require a modification of the steady state level of the real exchange rate is examined in terms of a model of staggered prices and real wealth effects although wealth effects are necessary for overshooting it is shown that their actual values are of no particular relevance in fact overshooting is shown to be more likely the smaller is the real wealth effect in the demand for tradables a key and counterintuitive result is that overshooting is more likely the higher is the frequency of price changes

how should control theory be used to calculate a time consistent government policy we study different solutions to a simple one dimensional linear quadratic game with a large number of private agents and a government a time consistent solution is defined as a solution to the hamilton jacobi bellman equation i e as a policy for which the government has noprecommitment capability this solution is compared to a policy where the government has an instantaneous pre commitment i e an equilibrium in which the government has a period by period leadership in both cases we show how control theory should be applied to calculate the equilibrium and how to relate these equilibria to the differential game literature

exchange rate based stabilization imperfect competition and supply side effects abstract this paper studies exchange rate based stabilization programs in the context of a dynamic general equilibrium model for a small open economy that incorporates imperfect competition a backward looking wage setting and an endogenous labor supply in contrast to previous results the analysis shows that a permanent disinflation leads to a sustained expansion in the domestic sector and a slow inflation convergence this study also shows that a temporary stabilization replicates a boom recession cycle these results suggest that a backward looking wage setting and an endogenous labor supply are the key ingredients for reproducing the stylized facts of exchange rate based stabilization

the contribution of tourism development to economic growth in the korean economy abstract this study investigates the causal relations between tourism growth and economic expansion for the korean economy by using engle and granger two stage approach and a bivariate vector autoregression var model two principle results emerge from this study first the results of a cointegration test indicate that there is no long run equilibrium relation between two series second the outcomes of granger causality test imply the one way causal relationship of economic driven tourism growth the hypothesis of tourism led economic growth is not held in the korean economy this consequence is supported by testing the sensitivity of causality test under different lag selections along with the optimal lag

from welfare to work does the neighborhood matter abstract this paper investigates whether individual transition rates from welfare to work are influenced by neighborhood effects we use a unique administrative database on welfare recipients in rotterdam the second largest city of the netherlands we find that conditional on personal characteristics there is a negative relationship between the neighborhood unemployment rate and the transition rate from welfare to work of young dutch welfare recipients we do not find any neighborhood effects for older dutch welfare recipients and non dutch welfare recipients when performing some sensitivity analyses this result is robust to different specifications

the speculative attack on the peso and the real exchange rate argentina 1979 1981 abstract this article applies a speculative attack model to argentina during its pre announced exchange rate system from january 1 1979 to june 30 1981 the model attempts to verify a rule whereby if domestic credit growth exceeds the rate of currency depreciation two things occur first the domestic price of non traded goods rises relative to the price of traded goods second foreign reserves decline until a point when a sudden speculative attack depletes remaining reserves causes a precipitous fall in the relative price of non tradables and forces the country onto a floating exchange rate regime in some important respects the model captures the argentinian experience yet in other respects if fails to do so

transitory shock or structural shift the impact of the early 1980s recession on british regional unemployment this paper examines the impact of the early 1980s recession on regional unemployment in britain more specifically it seeks to evaluate the hypothesis that this recessionary shock was so severe that it caused an upward structural shift in the underlying mean unemployment rates of the regions this proposition is analysed using dickey fuller tests for difference versus trend stationarity and the augmented structural shift and trend break time series models developed by perron the results suggest that the apparent stochastic non stationarity in regional unemployment over the period 1965 95 is in fact due to an upward structural shift in regional mean unemployment rates in 1980 furthermore the nature of this shift appears to have differed as between the northern and southern regions of the country

optimal anti inflation programs in semi industrialized economies orthodox versus heterodox policies abstract the paper characterizes the optimal time consistent anti inflation program in a small open semi industrialized economy when policy makers choose the rate of exchange rate crawl the rate of change of fiscal spending and a wage and price control parameter to minimize deviations of output and inflation the optimal program involves a rapidly decelerating rate of crawl a sharp reduction in spending and a short initial period of wage and price controls the paper also assesses the importance of controls in helping to reduce the output loss associated with fighting inflation

the argentine stabilization plan of december 20th abstract in this paper an analytical model is developed to incorporate the essential characteristics of the stabilization plan implemented in argentina in january 1979 the model is based upon a set of simplifying assumptions that only approximate the complexity of the real world it is assumed that the expectations of inflation and the degree of excess demand or supply in the non traded goods market are the main intermediate determinants of the rate of inflation in that market the rate of change of prices of traded goods being determined by the external inflation together with the rate of devaluation treating thus the external rate of inflation as exogenous the only instrument available for influencing the rate of inflation in the long run is the rate of devaluation since the model assumes a fixed exchange rate regime the money supply is endogenous and hence unsuitable as an instrument of economic policy

stabilization with liberalization an evaluation of ten years of chile s experience with free market policies 1973 1983 the recent post 1973 economic experience of chile has attracted considerable attention both from professional economists and from the media most observers have been particularly impressed by the sharp contrasts observed in chile in such a short period of time for example in 1973 chile had one of the highest rates of inflation in the world over 600 whereas in 1981 it experienced one of the lowest rates of inflation 9 5 also in 1975 real gnp declined by 12 9 but during 1977 80 real gnp grew at an average rate of 8 5 per annum in 1982 however the country faced a new recession with real gnp dropping by 14 5 in 1983 the gnp was reduced further by 2 3 the fact that these episodes developed while the military government was actively pursuing free market oriented policies that greatly liberalized the economy adds considerable interest to the chilean case 2 the year 1973 marked an important turning point in chile s economic and political history in september of that year the military took over the government from president salvador allende and a period of dramatic economic changes began chile was transformed from an economy isolated from the rest of the world with strong government intervention into a liberalized world integrated economy where market forces were left free to guide most of the economy s decisions the period 1973 81 was characterized by important achievements inflation was greatly reduced the government deficit was virtually eliminated the economy went through a dramatic liberalization of its foreign sector tariffs were reduced to a uniform 10 level and prices including interest rates were full liberalized probably one of the most interesting aspects of the chilean economy during this period is that major

sticky inflation and the real effects of exchange rate based stabilization abstract this paper tests the empirical validity of the forward looking pricing hypothesis using data from four exchange rate based stabilization erbs episodes it finds that backward looking components of inflation play an important role in inflation dynamics in some cases exceeding the importance of forward looking components the paper then shows that the presence of empirically relevant degrees of inflation stickiness increases the size of the real exchange rate appreciation predicted by an imperfect credibility model of erbs the 12 real appreciation predicted by the sticky inflation model is a 70 improvement over the predictions of the fully forward looking pricing setup but as in other erbs models still falls short of matching the real appreciations observed in practice

backward looking indexation credibility and inflation persistence abstract inflation persistence is a stylized fact after disinflation standard staggered prices models show very little or no inflation persistence and hence are of little use when inflation is sticky in this paper i present a model that on the one hand is consistent with the evidence of sticky inflation and on the other can be directly incorporated into modern intertemporal optimizing models the model modifies calvo s calvo g 1983a staggered contracts and exchange rate policy in j a frenkel ed exchange rates and international economics university of chicage press chicago il calvo g 1983b staggered wages in a utility maximization framework journal of monetary ecomomics 12 3 383 393 exclusively forward looking model and includes a backward looking component it encompasses the two extreme cases of purely forward and backward looking price setting i show how the model can be used in open economy stabilization programs this is not the first model including a form of backward indexation in a staggered prices setting however it has the advantage of keeping the analytical elegance of the calvo model while enhancing its dynamics

inflation inertia and credible disinflation abstract we develop a model of optimizing forward looking staggered price setting where even fully credible disinflations display a delayed and gradual inflation response and significant output losses there is a welfare trade off between these output losses and the gains from smaller inflationary distortions for reasonable parameter values disinflation improves welfare and more so if it is phased in gradually the pricing assumption of our model yields dynamics that are similar to models of sticky information but its state space is much simpler thereby allowing for the application of standard linearization methods

menu costs and the neutrality of money a model of endogenous price adjustment under money growth is presented firms follow s s pricing policies and price revisions are imperfectly synchronized in the aggregate price stickiness disappears and money is neutral the connection between firm price adjustment and relative price variability in the presence of monetary growth is also investigated the results contrast with those obtained in models with exogenous fixed timing of price adjustment

exchange rate pass through and inflation a nonlinear time series analysis abstract this paper investigates the relationship between the exchange rate pass through erpt and inflation by estimating a nonlinear time series model based on a simple theoretical model of erpt determination we show that the dynamics of erpt can be well approximated by a class of smooth transition autoregressive star models using the past inflation rate as a transition variable we employ several u shaped transition functions in the estimation of the time varying erpt to us domestic prices the estimation result suggests that declines in the erpt during the 1980s and 1990s are associated with lowered inflation

stabilization dynamics and backward looking contracts abstract exchange rate based stabilizations often result in an initial output expansion one explanation for this phenomenon has been that in the presence of inflation inertia a reduction in the nominal interest rate causes the domestic real interest rate to fall thus increasing aggregate demand this paper reexamines this issue in the context of an intertemporal optimizing model in contrast to previous results the analysis shows that if the intertemporal elasticity of substitution is smaller than the elasticity of substitution between traded and home goods a permanent reduction in the rate of devaluation leads to a fall in aggregate demand

tourism expansion tourism uncertainty and economic growth new evidence from taiwan and korea abstract this study examines the causal relationship between tourism expansion and economic growth in two asian countries taiwan and south korea an egarch m model with uncertainty factors is employed to examine the direction of causality between tourism expansion and economic growth as well as the impulse impacts of uncertainty on both variables the results indicate that the tourism led economic growth hypothesis is supported for taiwan while a reciprocal causal relationship is found for south korea the significant impacts of uncertainty on growth are also identified

detrending stylized facts and the business cycle the stylized facts of macroeconomic time series can be presented by fitting structural time series models within this framework we analyse the consequences of the widely used detrending technique popularised by hodrick and prescott 1980 it is shown that mechanical detrending based on the hodrick prescott filter can lead investigators to report spurious cyclical behaviour and this point is illustrated with empirical examples structural time series models also allow investigators to deal explicitly with seasonal and irregular movements that may distort estimated cyclical components finally the structural framework provides a basis for exposing the limitations of arima methodology and models based on a deterministic trend with a single break

transitions from welfare and the employment prospects of low skill workers this study examines the effects that labor market conditions and welfare policy changes had on single mothers welfare participation and economic outcomes using longitudinal individual level data from the 1992 and 1993 panels of the survey of income and program participation sipp the study uses special versions of the sipp panels that include state and county identifiers and links the individual information to county specific measures of low skill employment opportunities and state measures of welfare policies it estimates transition models of program entry and exit and regression models of economic outcomes the study finds that employment conditions and welfare benefit levels were significant determinants of single mothers welfare participation and economic success over the period 1992 95 however it does not find statistically distinguishable differences in participation and economic success between states that did and did not reform their welfare programs through waivers to the federal rules jel classification i3 j3

the output inflation trade off when prices are costly to change the output inflation trade off is investigated in a rational expectations equilibrium economy in which costly price setting makes it inefficient for agents to vary their prices at every instant it is shown that sticky prices are not some exogenous source of output fluctuation but result from the monetary policy process an economy with slow and counterinflationary money growth exhibits staggered changes in sticky prices as assumed in some new keynesian analyses an economy with fast money growth and a high degree of monetary accommodation exhibits either flexible prices or bunched frequently changing sticky prices

the wage price spiral this paper rehabilitates the old wage price spiral it shows that after an increase in aggregate demand the process of adjustment of nominal prices and nominal wages results from attempts by workers to maintain or increase their real wage and by firms to maintain or increase their markups of prices over wages under continuous price and wage setting the process of adjustment would be instantaneous under staggering of price and wage decisions the adjustment takes time the more inflexible real wages and markups are to shifts in demand the higher is the degree of price level inertia and the longer lasting are the effects of aggregate demand on output

dynamic games and the time inconsistency of optimal policy in open economies it has been argued that the bretton woods system of pegged but adjustable exchange rates set up after world war ii was designed specifically to prevent the manipulation of exchange rates in pursuit of national macroeconomic objectives see r cooper so it is perhaps no coincidence that the ending of pegged rates has led to the re emergence of theories and policies involving such manipulation before the war when inflation was low and unemployment high in the major industrialised nations this involved competitive depreciation as countries tried to gain employment in the late 1970 s and early 1980 s however countries like the uk and the us have embarked on policies of competitive appreciation in order to cut inflation regarded as the first priority sharp movements in exchange rates however constitute a threat to orderly trade and stimulate protectionism as bergsten 1981 argues this abstract was borrowed from another version of this item

the employment dynamics of disadvantaged women evidence from the sipp understanding the employment dynamics of disadvantaged families is increasingly important we estimate duration models describing these dynamics for disadvantaged single mothers and use them to conduct a rich set of counterfactual analyses we use a misreporting model to correct for seam bias the problem that too many transitions are reported between reference periods in panel data we find effects of demographics minimum wages unemployment rates and maximum welfare benefits but not policy changes introduced through state welfare waivers on employment dynamics we find that two commonly used ad hoc methods of addressing seam bias perform substantially worse than our approach

the effects of minimum wages on the distribution of family incomes a nonparametric analysis an oft stated goal of the minimum wage is to raise incomes of poor or low income families we present nonparametric estimates of the effects of minimum wages on the distribution of family income relative to needs in the united states although minimum wages increase the incomes of some poor families the evidence indicates that their overall net effect is if anything to increase the proportions of families with incomes below or near the poverty line it would appear that reductions in the proportions of families that are poor or near poor should not be counted among the potential benefits of minimum wages

externalities from contract length an increase in the length of a firm s labor contract contributes to rigidity in the aggregate price level this increases the variance of aggregate demand but decreases the variance of other firms real wages under certain conditions the net effect is to increase the variance of other firms employment this negative externality implies that the equilibrium contract length in a decentralized economy is greater than the social optimum in other words wages are too rigid copyright 1987 by american economic association

stabilization policies in developing countries what have we learned abstract the paper reviews the recent experience with stabilization programmes in latin america in the light of traditional and monetarist models of inflation and the exchange rate the traditional model links both inflation and payments problems to budget deficits the monetarist model too believes that inflation is caused by fiscal deficits but it takes a more optimistic view of stabilization full purchasing power parity and perfect capital mobility make stabilization just a question of the appropriate exchange rate policy and the proper rate of domestic credit creation the traditional view is substantially right as a long run model but it fails in the dynamics the monetarist model is as we know now fundamentally wrong as a short run description of the possibilities of inflation control there is need and room for a paradigm that places emphasis on the debt money mix in financing the budget on the stickiness of inflation rates and on the place of short run real exchange rate and real interest rate variations that these are key features of the transition phase is amply borne out by the devasting and unsuccessful experiences with monetarist stabilization in argentina chile and brazil

credit rationing and capital accumulation this paper develops a dynamic partial equilibrium analysis of how financial policy affects capital accumulation when bank loans are rationed and subsidized the underlying specification of intertemporal behavior is critical loan policy often has qualitatively different effects on capital accumulation in overlapping generations and infinite horizon models it is also shown that in the infinite horizon case the results are extremely sensitive to the timing of private sector expectations policies that promote reduce capital accumulation when unanticipated induce capital decumulation accumulation when anticipated copyright 1991 by the london school of economics and political science

the equilibrium and optimal timing of price changes this paper studies the welfare properties of the equilibrium timing of price changes staggered price setting has the advantage that it permits rapid adjustment to firm specific shocks but the disadvantages that it causes unwanted fluctuations in relative prices and that by creating price level inertia it can increase aggregate fluctuations because each firm ignores its contribution to these problems staggering can be a stable equilibrium even if it is highly inefficient in addition there can be multiple equilibria in the timing of prices changes indeed whenever there is an inefficient staggered equilibrium there is also an efficient equilibrium with synchronized price setting

staggered price setting with endogenous frequency of adjustment abstract a model of staggered price setting in which the frequency of price changes is endogenous is presented

examination of taiwan s travel and tourism market cycle through a two period markov regime switching model abstract this study analyzes the taiwan travel and tourism t t market cycle according to data of the weighted taiwan tourism stock index from january 1997 to august 2015 the two period markov regime switching model identifies two distinct regimes of the t t cycle and incorporates a specific set of mean and variance parameters for each period to control for the structural changes in taiwan s t t market the effect of china visitor arrivals to taiwan on the t t market is also verified the empirical findings offer essential information and policy implications for taiwan s government tourism policymakers and business managers

obstacles to disinflation what is the role of fiscal expectations persistently high expected inflation often makes it difficult for policy makers to recover from inflationary episodes without substantial output losses using survey data from eleven disinflation episodes we can assess whether the more or less sluggish decline of inflation rates towards lower target levels is related to backward looking pricing behavior or to imperfect credibility of the stabilization efforts we find that expectations of future inflation play a much more important role than past inflation in shaping the inflation process second we find that an improvement in various measures of fiscal balances significantly reduces inflation expectations this evidence suggests that when attempting to stabilize inflation priority should be given to building fiscal credibility oya celasun r gaston gelos and alessandro prati

modern hyper and high inflations since 1947 hyperinflations by cagan s definition in market economies have been rare much more common have been longer inflationary processes with inflation rates above 100 percent per annum based on a sample of 133 countries and using the 100 percent threshold as the basis for a definition of very high inflation episodes this paper examines the main characteristics of such inflations among other things we find that i close to 20 percent of countries have experienced inflation above 100 percent per annum ii higher inflation tends to be more unstable iii in high inflation countries the relationship between the fiscal balance and seigniorage is strong both in the short and long run iv inflation inertia decreases as average inflation rises v high inflation is associated with poor macroeconomic performance and vi stabilizations from high inflation that rely on the exchange rate as the nominal anchor are expansionary

tourism demand for italy and the business cycle this study provides a strategy for modelling the effect of the business cycle on tourism demand under the rationale that tourism cycles are heavily influenced by lagged effects of the overall business cycle using quarterly data on overnight stays in italian hotels both domestic and inbound between 1985 and 2004 we adopt a structural time series approach to evaluate two alternative models the first with a latent cycle component lcc and the second based on specific economic explanatory variables xcv the two models are compared in terms of explanatory power best fit residual diagnostics and forecasting ability the results show similar performances the policy implication is that the xcv model can be used for calibrating countercyclical interventions in tourism policy

monetary policy rules and the indicator properties of asset prices abstract we investigate relationships between asset prices and inflation in a modern keynesian model in which monetary policy controls inflation by manipulating the federal funds rate the indicator properties of asset prices are quite sensitive to the monetary policy rule including the asset prices themselves in the reaction function can invert the sense of the indicator properties targeting the asset prices is tantamount to targeting the real interest rate when all of the weight in the reaction function is placed on asset prices the real rate converges so rapidly that policy loses control of inflation

on inflation and output with costly price changes a simple unifying result this paper determines the real effects of credible disinflation when price setting is staggered the results are surprising a fairly quick disinflation causes a boom this finding suggests that nominal price rigidity alone does not explain why disinflation is costly in actual economies this abstract was borrowed from another version of this item

reserves and the managed float a search for the essentials we examine the stability of rules that determine the rate of devaluation as a function of the level of reserves the analysis is conducted in terms of an overlapping generations and a sidrauski type model with rational expectations and without capital mobility on the whole the analysis confirms results by rodriguez 1981 in a substantially different model by which high speeds of adjustment tend to provoke instability

a stock flow analysis of the welfare caseload this paper reconsiders the methods used in previous studies to assess the welfare caseload movements during the 1990s we develop a model in which the welfare caseload is the net outcome of past flows onto and off of the caseload and show that such a stock flow model can explain some of the anomalous findings in previous studies we then estimate the stock flow model using california administrative data we find that approximately 50 percent of the caseload decline in california can be attributed to the declining unemployment rate these estimates are more robust and larger than those obtained when applying more typical methods to the same california data

when do women use aid to families with dependent children and food stamps the dynamics of eligibility versus participation this paper investigates dynamic patterns in the relationship between eligibility and participation in the aid to families with dependent children afdc and food stamp programs using monthly longitudinal data from the survey of income and program participation the results indicate that there are many relatively short eligibility spells that do not result in program participation and end with increases in income participation is most likely to occur among women with lower current and future earnings opportunities and is affected by locational and policy parameters those who elect to participate in these programs tend to start receiving benefits almost immediately upon becoming eligible a substantial number of women exit these programs before their eligibility ends among at least some of these women it is likely that unreported changes in income are occurring in 1989 if all eligible single parent families had participated in afdc and food stamps benefit payments in these programs would have been 13 5 billion higher

optimal price dynamics and speculation with a storable good this paper analyzes as a dynamic game the optimal price and storage strategies of respectively a the seller of a storable good who must keep pace with inflation but incurs a cost to changing his price b his customers who speculate on the timing of price adjustments to buy and store just before a unique markov perfect equilibrium is shown to exist and is fully characterized rt generally involves a phase of mixed strategies during which the seller tries to deter speculation by injecting uncertainty into its price dynamics while speculators store in increasing numbers with possibly a final run on the good the stochastic price policies of a large number of such firms are shown to aggregate back to a price index growing at the rate of general inflation in response to which they arose the model thus establishes that a a constant rate of aggregate inflation can at the same time generate and cover up significant uncertainty and social costs at the microeconomic level b speculation can be destabilizing and socially wasteful even in the absence of shocks and imperfect information most importantly they provide a theoretical foundation for the frequently encountered claim that inflation causes price uncertainty
