ANXIETY AND PERFORMANCE: AN ENDOGENOUS LEARNING‐BY‐DOING MODEL*

In this article, we show that a standard economic model, the endogenous learning‐by‐doing model, captures several major themes from the anxiety literature in psychology. In our model, anxiety is a fully endogenous construct that can be separated naturally into its cognitive and physiological components. As such, our results are directly comparable with hypotheses and evidence from psychology. We show that anxiety can serve a motivating function, which suggests potential applications in the principal–agent literature.

FIRST‐BEST FISCAL POLICY WITH SOCIAL STATUS*

This paper examines the first‐best fiscal policy in a stochastic, infinite‐horizon representative agent model that exhibits consumption‐enhanced as well as wealth‐enhanced social status in the household utility. We show that the first‐best labour tax rate is a positive constant that is used to correct negative consumption externalities. The first‐best tax rate on capital income is also positive in order to overturn agents' status‐seeking capital over‐accumulation. Moreover, we find that in sharp contrast to a conventional automatic stabilizer, the first‐best capital tax rate moves in the opposite direction with shocks to firms' production technology, thus exacerbating the business cycle.     

MONETARY–FISCAL INTERACTIONS WITH A CONSERVATIVE CENTRAL BANK

We study macroeconomic stabilization when monetary and fiscal policies interact via their effects on output and inflation and the monetary authority is more conservative than the fiscal. We find that monetary–fiscal interactions result in poor macroeconomic stabilization. With both policies discretionary, the Nash equilibrium is suboptimal with higher output and lower inflation than optimal; the Nash equilibrium may be extreme with output higher and inflation lower than either authority want. Leadership equilibria are not second best. Monetary commitment is completely negated by fiscal discretion and yields the same outcome as discretionary monetary leadership for all realizations of shocks. But fiscal commitment is not similarly negated by monetary discretion. Optimal macroeconomic stabilization requires either commitment of both monetary and fiscal policies, or identical targets for both authorities – output socially optimal and inflation appropriately conservative – or complete separation of tasks.     

HOW LARGE WILL BE THE EFFECT OF CHINA'S FISCAL STIMULUS PACKAGE ON OUTPUT AND EMPLOYMENT?

This paper estimates the effect of China's fiscal stimulus package on output and employment. The input–output analysis shows that the package has a multiplier of approximately 0.84 in the short run, generating 18–20 million new jobs in non‐farming sectors in the first year. A dynamic structural model shows that the multiplier is around 1.1 in the medium run as fiscal spending leads to higher household consumption and corporate investment over time. The size of the fiscal multiplier also depends on the cyclical conditions of the economy, the policy environment and the distribution of funds across sectors.     

THE SHORT-RUN EFFECTS OF FISCAL POLICY WITH USEFUL GOVERNMENT EXPENDITURE

This paper examines the short-run effects of changing government expenditure on output, consumption and employment. It attempts to combine the Public-Finance and macroeconomic approaches to the analysis of fiscal policy by introducing government expenditure which is 'useful' in consumption into an ISLM-type macro model which is derived from the singleperiod maximizing decisions of households and firms and which includes a government budget constraint.
The principal conclusion is that the effects of fiscal policy on output and employment depend on the 'efficiency' of government expenditure. The more efficiently government expenditure meets consumption needs, the less effective is fiscal policy to the point where the fiscal-policy multiplier may be negative.     

MONETARY AND FISCAL POLICY EFFICIENCY AND COORDINATION IN A MULTI‐SECTOR OPEN‐ECONOMY GENERAL EQUILIBRIUM MODEL

The paper analyzes monetary and fiscal stabilization and coordination in a multi‐sector stochastic new open economy macroeconomics (NOEM) model. It first aims to assess the capacity of fiscal and monetary policy to reduce or eliminate the negative welfare effects of an unanticipated productivity shock affecting some or all of the sectors in each country. Second, it evaluates the possible gains from international monetary cooperation as well as the impact of active fiscal policy on the welfare performance of monetary policy. The setup also allows for international asymmetry concerning the uncertainty over the shocks. The results show that monetary and fiscal policies are efficient tools of stabilization and under several conditions they can replicate the flexible‐price equilibrium. However, their welfare performance is not necessarily increased when both monetary and fiscal policies react to shocks at the national level. The existence of bilateral gains from monetary cooperation depends on the degree of asymmetry concerning the uncertainty over the shocks.     

FISCAL DECENTRALIZATION AND ECONOMIC VOLATILITY: EVIDENCE FROM STATE‐LEVEL CROSS‐SECTION DATA OF THE USA*

This paper examines the implications of fiscal decentralization for economic stability. It has been discussed that fiscal decentralization reduces the variance of GDP growth, due to the greater diversification of performance across jurisdictions. We examine this theoretical result using a panel data set of the 50 states of the USA over the period of 1992–1997. We show that the theoretical specification of the production function is supported. We also show a negative significant relationship between fiscal decentralization and economic volatility. The results are robust when we take into account the endogeneity of fiscal decentralization.     

FISCAL POLICY IN AN ENDOGENOUS GROWTH MODEL WITH PUBLIC CAPITAL AND POLLUTION

This paper studies the growth and welfare effects of fiscal policy in an endogenous growth model with public capital and environmental pollution. I assume that pollution is due to aggregate production, and that it does not have a direct effect on production but only reduces household utility. I study the growth effects of fiscal policy for the model on the balanced growth path, taking transition dynamics into account. I then analyse the welfare effects of fiscal policy along the balanced growth path. Finally, I show how the fiscal parameters must be set so that the competitive economy replicates the social optimum.     

我国应对国际金融危机的财税政策研究

国际金融危机对我国实体经济造成冲击的主要原因是近些年来我国经济增长严重依赖外需。我国内需不足主要是由社会保障制度不健全以及低收入群体所占比重相对较大造成的。当前国家扩大内需的财税政策也应着眼于完善社会保障制度和改善收入分配两个方面。     

我国财政政策非线性效应的实现机制及动态特征研究

本文基于财政调整时期的内生划分方法,采用STR模型对于我国1980-2012年间财政政策非线性效应的实现机制与动态特征进行实证分析,结果发现：一是我国财政政策非线性效应主要是经由消费渠道发生,而且是通过影响消费者预期产生。二是财政政策非凯恩斯效应在不同条件下与财政政策工具之间的搭配组合存在一定差异。其中,当基本预算余额/潜在GDP小于临界值-0045 0时,财政收入对居民消费需求存在非凯恩斯效应;反之,财政支出表现出一定程度的非凯恩斯效应。三是财政政策调整的幅度是居民消费需求非凯恩斯效应产生的重要因素,但财政政策调整的组成成分与政府的初始债务规模不是非凯恩斯效应产生的先决条件。本文研究结论不仅可以为政府制定财政政策提供理论依据与决策参考,还有助于改善我国财政政策实践的操作效率和运行效果。     

N‐FIRM OLIGOPOLY WITH GENERAL ISO‐ELASTIC DEMAND

In this note oligopoly with iso‐elastic demand is analysed. Unlike previous studies we consider general iso‐elastic demand rather than the case of unit elasticity. An n‐firm Nash‐Cournot equilibrium for the case of heterogeneous constant marginal costs is derived. The main result is a closed‐form solution that shows the dependency of the equilibrium on the elasticity of demand and the share of industry costs. The result has applications to a wide range of areas in oligopoly theory by allowing comparisons across markets with different elasticities of demand.     

后危机时代中国与 欧美财政政策协调研究

本文通过达瓦斯两国财政离散度的测算和MSVAR模型对中美、中欧财政政策协调进行定量分析。结果表明,中欧的财政政策相关程度比中美要高,这主要是由于中国地方财政分权模式与欧元区相似,以及美元霸权地位的“资本双向流动模式”所决定。债务危机后需要各经济体进行统一协调的财政方案,否则一个开放经济体政策的作用效果会被抵消。目前中国在国际政策协调中仍处于从属地位,未来美国的财政赤字将大幅下降,同时欧元区的赤字也将波动下降,中国要加快做好经济结构调整。     

WAGE‐RISE CONTRACT AND QUANTITY COMPETITION WITH PROFIT‐MAXIMIZING AND LABOUR‐MANAGED FIRMS

This paper examines the behaviours of a profit‐maximizing firm and a labour‐managed profit‐per‐worker‐maximizing firm in a two‐stage quantity‐setting model with a wage‐rise contract as a strategic commitment. The paper then shows that there exists a unique equilibrium that coincides with the Stackelberg solution where the profit‐maximizing firm is the leader and the labour‐managed firm is the follower.     

DYNAMIC CONTRACTS WITH WORKER MOBILITY VIA DIRECTED ON‐THE‐JOB SEARCH

This article proposes a model with dynamic incentive contracts and on‐the‐job search in a frictional labor market. The optimal long‐term contract exhibits an increasing wage–tenure profile. With increasing wages, worker effort also increases with tenure. These two features imply that the probabilities of both voluntary and involuntary job separation decrease with both job tenure and the duration of employment. Given these results, workers experience differing labor market transitions—between employment, unemployment, and across different employers—and the equilibrium generates endogenous heterogeneity among ex ante homogeneous workers.     

SEQUENTIAL TWO‐PLAYER GAMES WITH AMBIGUITY*

If players' beliefs are strictly nonadditive, the Dempster–Shafer updating rule can be used to define beliefs off the equilibrium path. We define an equilibrium concept in sequential two‐person games where players update their beliefs with the Dempster–Shafer updating rule. We show that in the limit as uncertainty tends to zero, our equilibrium approximates Bayesian Nash equilibrium. We argue that our equilibrium can be used to define a refinement of Bayesian Nash equilibrium by imposing context‐dependent constraints on beliefs under uncertainty.     

FREE VERSUS SECOND‐BEST ENTRY IN COURNOT OLIGOPOLIES WITH FIRM‐SPECIFIC NETWORKS

This paper endogenizes the number of firms in an industry with positive network effects, complete incompatibility, and firms that compete in quantity. To this end, we compare two possibilities: free entry and second‐best number of firms (the one that maximizes social welfare). We show that with business‐stealing competition, free entry yields, in general, more firms than the socially optimal solution. In addition, we find that by the nature of the industry with firm‐specific networks, total production may be greater or lower under free entry than with a regulator; moreover, some industries attain their maximum social welfare with a monopoly.     

BUNDLING IN AUCTIONS WITH NON‐LINEAR VALUATIONS*

We examine when a revenue‐maximising auctioneer prefers to auction a homogenous product in one bundle (a single‐object auction) than to sell the item in two or more shares. When the items are super‐additive the auctioneer always prefers a single‐object auction. When the product valuations are sub‐additive, the auctioneer is more likely to choose a share auction when there are a large number of potential bidders. When there are a small number of bidders the auctioneer will tend to prefer a single‐object auction.     

LIFE‐CYCLE LABOR SEARCH WITH STOCHASTIC MATCH QUALITY

In the United States, unemployment, job finding, and separation rates decline as worker age increases. To explain these facts, we build a search and matching model of the labor market that incorporates a life‐cycle structure and features random match quality as well as human capital accumulation. The calibrated model successfully reproduces the empirical patterns of unemployment and job transition rates over the life cycle and generates plausible wage implications. We then explore the efficiency implications of the model and find that the differences between the market and planner allocations are more important for older workers.
