detecting multiple factors in panel data an application on the growth of local regions in china abstractdue to unbalanced growth in china s local regions we construct a panel data model with multiple common factors to examine the differences among the growth factors in these areas this article shows the various impacts from the supply and demand sides on economic growth different from the demand side the supply side impacts have permanent influences this article focuses on these deep and profound impacts to explain the reasons behind china s fast economic growing by using data on 27 regions from 1958 to 2013 we summarize the main permanent influences along three lines the first comes from the coastal regions which have learned modern technology and systems from foreign companies such as in guangdong zhejiang fujian and liaoning the second comes from big cities such as beijing and shanghai in which a huge migration has given the companies opportunities to recruit excellent workers making the resource allocation specialized and more efficient the third is from the government s major p

producer attitudes toward peanut market alternatives an application of multivariate probit joint estimation attitudes of peanut producers toward different market alternatives were analyzed assuming the absence of the government support program a multivariate probit joint estimation model for ungrouped data was utilized to ascertain profiles of producers favoring private treaty markets and proposed organized markets the joint estimation model allows for and measures correlation among market alternatives for greater accuracy in profile analysis the analysis suggests considerable support for all three of the proposed organized markets however choice of alternatives should be considered by a group of potential traders selected on the basis of the profile analysis

selling at the farmgate or traveling to market using detailed survey data from uganda this article examines whether coffee producers sell to itinerant traders or directly to markets where they can get a higher price but must incur a transport cost we find that selling to the market is more likely when the quantity sold is large and the market is close by wealthy farmers are less likely to sell to the market possibly because the shadow value of their time is higher but if they have a large quantity of coffee for sale they are more likely to sell it to the market they are also more likely to travel to a distant market these findings are consistent with their better ability to pay for public transportation we find no evidence that the decision to sell at the farmgate is driven by a self control motive

on some computational aspects of equilibrium business cycle theory abstract this paper evaluates the accuracy of quadratic approximate methods in the context of a simple real business cycle model the level of accuracy is found to be very high on the face of the results reported here we are confident that the different computation methods proposed to date in this literature can be employed interchangeably

aggregate stochastic implications of the life cycle hypothesis this paper sets forth some key aggregate stochastic implications of the modigliani brumberg 1980 life cycle hypothesis and explores the extent to which a properly aggregated life cycle model can help to explain the first and second moment properties of changes in per capita consumption the principal finding of the paper which to my knowledge is new is that smooth per capita consumption in the presence of permanent shocks to per capital labor income is exactly the outcome one should expect from a properly aggregated life cycle model in which saving for retirement as well as for consumption smoothing is a motive for asset accumulation

multivariate estimates of the permanent components of gnp and stock prices the economic assumption that a present value relation holds between consumption and income and between stock prices and dividends or the statistical assumption that the consumption income ratio and the dividend price ratio are stationary imply that the permanent or random walk component in each series of a pair must be the same as the permanent component in the other series of a pair either assumption then allows us to estimate the variance of the permanent component of one series gnp stock prices from the variance of the permanent component of the other consumption dividends or from the covariance of the two series permanent components this paper presents such estimates and finds that the permanent components are about half those estimated by similar univariate methods a series of recent papers has examined the importance of a potential unit root to the behavior of real gnp campbell and mankiw 1986 1987 cochrane 1986 clark 1987 and stock prices fama and french 1986 lo and mai if by 0 the series is stationary the response can be any real number which is the innovation in these estimates instead of forcing us to ask the dichotomous question is there a unit root or not they allow us to continuously measure the importance of a potential unit root the actual estimating technique used in these papers varied somewhat cochrane poterba and summers and lo and mai if a series is stationary the variance of k differences will tend to a precursor to this paper appeared under the title spectral density estimates of unit roots we thank masanao aoki lam hansen masao ogaki and chris sims for helpful suggestions the computer programs and data used in this paper are available on request from the authors

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

international risk sharing and european monetary unification abstract we explore income and consumption smoothing patterns among european community ec countries and among oecd countries during the period 1966 90 we find that for oecd as well as for ec countries about 40 percent of shocks to gdp are smoothed at the one year frequency with about half the smoothing achieved through national government budget deficits and half by corporate saving at the three year differencing frequency only 25 percent of shocks to gdp are smoothed mainly via government lending and borrowing in the absence of alternative income and consumption smoothing mechanisms the restrictions on budget deficits imposed by the maastricht treaty should be relaxed to allow governments to run large temporary deficits in response to output shocks

trends and cycles in macroeconomic time series two structural time series models for annual observations are constructed in terms of trend cycle and irregular components the models are then estimated via the kalman filter using data on five u s macroeconomic time series the results provide some interesting insights into the dynamic structure of the series particularly with respect to cyclical behavior at the same time they illustrate the development of a model selection strategy for structural time series models

straight time and overtime in equilibrium abstract we formulate an equilibrium model of straight time and overtime wages by imposing restrictions on agents consumption sets and using a commodity space that includes employment lotteries we extract some time series implications from a linear quadratic approximation to our model evaluated at particular parameter values we use our model informally to interpret some features of observed time series for wages and employment

pricing efficiency in centralized and noncentralized markets pricing efficiency in centralized markets is compared with that in noncentralized markets on the basis of a price formation model centrally discovered prices are hypothesized to adjust more slowly to equilibrium but to have lower unpredictable variability than noncentrally discovered prices these hypotheses are borne out strongly in market experiments mean squared error is found to be lower in centralized than in noncentralized trading suggesting centralized markets are the more price efficient

real business cycle models and the forecastable movements in output hours and consumption the authors study the movements in output consumption and hours that are forecastable from a vector autoregression and analyze how they differ from those predicted by standard real business cycle models they show that actual forecastable movements in output have a variance about one hundred times larger than those predicted by the model the authors also find that forecastable changes in the three series are strongly positively correlated with each other on the other hand for parameters whose implications are plausible in other respects the model implies that output consumption and hours should not all be expected to move in the same direction copyright 1996 by american economic association

time series implications of friedman s permanent income hypothesis abstract the ability of the permanent income hypothesis pih to explain aggregate time series data has been seriously challenged over the last ten years based upon the implications of a version of the pih developed by hall 1978 and flavin 1981 there are however inconsistencies between the hall flavin version of the pih and pure time series representations of the pih based upon friedman s original formulation this paper considers the force of the recent challenges to the pih when the implications of the pih are drawn from a friedman muth version of the pih rather than the hall flavin version

how risky is consumption in the long run benchmark estimates from a robust estimator the long run standard deviation lrsd of consumption growth is a key moment in determining risk premiums under epstein zin preferences standard estimators of the lrsd are biased downward and have poor confidence interval coverage making them overreject the long run risk model this paper studies a new estimator with smaller bias and accurate confidence intervals standard long run risk calibrations are still rejected in the data the lrsd of consumption growth in the postwar sample is estimated to be 2 5 per year with an upper bound to the 95 confidence interval of 4 9 these values can be taken as benchmarks for future calibrations received october 29 2014 accepted february 18 2016 by editor leonid kogan

the cyclical component of u s economic activity quarterly data on industrial production and deflated gross national product in the united states from 1947 through 1985 are decomposed into independent nonstationary trend and stationary cycle components using kalman filtering and smoothing techniques estimates of the model parameters imply that at least half of the quarterly innovation in u s economic activity can be attributed to a stationary cyclical component that persists over periods of time as long as five years this finding is inconsistent with the hypothesis that most of the apparent variation in u s economic activity can be attributed to a nonstationary trend component

robert m solow s neoclassical growth model an influential contribution to economics in 1956 robert solow s paper a contribution to the theory of economic growth 21 appeared in the quarterly jqurnal of economics the model this paper describes is a simple one it has a constant returns to scale aggregate production function with substitution between two inputs capital and labor the model is completed by assuming that a constant fraction of output is invested the discrete time version of the model is

is consumption insufficiently sensitive to innovations in income deaton 1986 has noted that if income is a first order autoregressive process in first differences then a simple version of friedman s permanent income hypothesis spih implies that measured u s consumption is insufficiently sensitive to innovations in income this paper argues that this implication of the spih is a consequence of the fact that it ignores the role of the substitution effect in the consumption decision using a parametric version of the standard model of economic growth the paper shows that very small movements in interest rates are sufficient to induce an empirically plausible amount of consumption smoothing since an overall evaluation of the model s explanation for the observed smoothness of consumption requires examining its implications for other aspects of the data the paper also explores some of these

technical progress and aggregate fluctuations abstract we compare the cyclical fluctuations exhibited by a stochastic growth model under various stochastic processes governing technical change all of which are highly autocorrelated the results obtained are quite sensitive to the precise form of this stochastic process in particular the results depend on whether growth is deterministic or stochastic and in each case are quite sensitive to the persistence of an innovation the model does a relatively poor job of accounting for features of observed business cycles when technical change is difference stationary and does a better job when technical change is trend stationary but highly autocorrelated

real business cycles in this paper we demonstrate how certain very ordinary economic principles lead maximizing individuals to choose consumption production plans that display many of the characteristics commonly associated with business cycles our explanation is entirely consistent with i rational expectations ii complete current information iii stable preferences iv no technological change v no long lived commodities vi no frictions or adjustment costs vii no government viii no money and ix no serial dependence in the stochastic elements of the environment we also provide a completely worked out example of the type of artificial economy we have in mind the time series properties of the example exhibit some major features of observed business cycles although this type of model may not be capable of explaining all of the regularities in actual business cycles we believe that it provides a useful well defined benchmark for assessing the relative importance of factors e g monetary disturbances

tax rate uncertainty and the sensitivity of consumption to income in an overlapping generations model abstract a well documented feature of u s data is that the aggregate consumption is a smoother process than income an overlapping generations model with a time nonseparable utility function is developed to characterize the effect of income tax uncertainty on the degree of consumption smoothness the model predicts that an increased tax uncertainty combined with tax financed production externality makes the aggregate consumption smoother for a plausible range of intertemporal substitution in consumption a calibration experiment indicates that the observed long term smoothness of aggregate consumption is consistent with the model s predicted consumption process
