Comparing new Keynesian models in the Euro area: a Bayesian approach

This paper estimates and compares four versions of the sticky price New Keynesian model for the Euro area using a Bayesian approach. We find that the average duration of price contracts is between two and four quarters, while the average duration of wage contracts is estimated to be below two quarters. Both mechanisms of price and wage indexation are not important when autocorrelated price markup shocks are introduced in the model. These results are in stark contrast to Smets and Wouters (2003): when we use their priors, our estimated posterior distributions are similar to theirs, but the models’ fit to the data is worse. We are thankful to the Econometric Modelling Unit at the European Central Bank for providing us with the Euro area data. We also thank two anonymous referees for helpful suggestions.

Does too much government spending depress the economic development of transition economies? Evidences from dynamic panel threshold analysis

This paper investigates the relationship between government size and economic growth and determines the optimal level of government spending to maximize economic growth. The paper applies a dynamic panel data analysis based upon a threshold model to test the threshold effect of government spending in 26 transition economies over the period spanning 1993–2016. According to the analysis results, government expenditures have a threshold effect on economic growth, and there is a non-linear relationship depicted as an Armey curve in these transition economies. The findings indicate that a government size above the threshold government spending level adversely affects economic growth, while a government size below the threshold level has a positive effect. Furthermore, there is a statistically significant relationship between the two variables above and below that optimal level, even if we divide the sample into developed and developing countries. Our findings suggest that governments in transition economies should consider optimal government size at around the estimated threshold level to support sustainable economic growth.     

Nominal rigidities, skewness and inflation regimes

The menu-costs model developed by Ball and Mankiw (BM) [Ball, L., Mankiw, N.G., 1994. Asymmetric price adjustment and economic fluctuations. Economic Journal 104 (423), 247–261; Ball, L., Mankiw, N.G., 1995. Relative-Price Changes as Aggregate supply shocks. Quarterly Journal of Economics 110 (1), 161–193] predicts that inflation is positively related to the skewness of price changes distribution. We test this prediction in different inflationary contexts: Spain (1975–2002) and Argentina (1960–1989). We find a positive inflation–skewness relationship in both countries at low inflation, even though the mean annual inflation rates were very different: 2.2% for Spain and 23% for Argentina. Therefore, the threshold of low inflation under which the menu-costs model is suitable is determined endogenously, and it depends on the inflationary experience of each economy. In the higher inflation periods skewness is not significant. Finally, our results suggest that the menu-costs model is not suitable beyond certain threshold of inflation.     

Monetary Rules and Deficit Shocks

Modern theory on interest rate rules is based on the representative agent framework with infinite-horizon consumers, thereby ignoring redistributions of the fiscal burden across generations due to deficit shocks. We show how the ‘Taylor principle’ relies on this restrictive assumption. In a dynamic New Keynesian general equilibrium model with overlapping generations, the existence of a unique stable rational expectations equilibrium may also occur under a passive monetary policy. However, active monetary policy is still required to stabilize the economy in response to fiscal shocks.

Public spending and growth: The role of government accountability

This paper examines the role of institutions in the nexus between public spending and economic growth. Empirical results based on a newly assembled dataset of 80 countries over the 1970–2010 period suggest that particularly when institutions prompt governments to be accountable to the general citizen does public capital spending promote growth. Taking account of the type of financing for this spending, we show that the growth-promoting effect under an accountable government appears to prevail for various financing sources, including a reallocation from current spending, an increase in revenue, and a rise in the budget deficit. However, government accountability does not seem to play a key role in the growth effects of current spending.     

Peaking of fiscal sizes of government

Transfers, spending, and tax revenue peaked as percentages of the gross national product (GNP) in most OECD countries during 1972–1992. The evidence suggests that a number of countries pushed transfers close to or perhaps beyond sustainable limits imposed by the Laffer curve. Namely: (i) stylized calculations of Laffer limits suggest peak fiscal sizes in the range of observed peaks in the countries with the greatest peak sizes; and (ii) the countries with the greatest peak sizes had the greatest declines in fiscal sizes from peaks until 1992.     

Fiscal policy,wealth divergence,and lifetime utility

Using a two-country dynamic optimization model where the less patient country decumulates and the more patient one accumulates wealth, we analyze spillover effects of lump-sum and consumption taxes. A lump-sum tax on a country definitely harms the other country through a change in the rate of interest. A lump-sum tax on either country always improves the less patient country's asset position. A consumption tax has no spillover effect, although it is Pareto-inferior. Applying these results into a closed-country context with heterogeneous agents, we also discuss policy implications of a discriminatory tax.     

财政投资对农村脱贫效应的边际递减趋势及对策

中国农村的改革开放取得了巨大的成功,同时也使农村的贫困问题凸现出来;财政投资是解决农村贫困问题的有效途径,然而财政投资的效率边界也使新世纪的扶贫工作面临新的课题.本文分析了农村财政投资对减贫的作用机理,并在此基础上给出了当前农村减贫中财政投资在不同地区、项目上的合理区间和运作方式.     

财政分权与经济增长

对H.Davoodi,D.Xie,and H.Zou的两篇文章中的内生增长模型进行了改进;把地方财政决算支出占国家决算支出的比重看作衡量财政分权的指标,并利用1986-2004年间的数据对财政分权对我国经济增长的作用进行了两组回归分析。发现在1986-1990年间我国的财政分权的比重过高阻碍了我国的经济增长;在1991-2004年间我国的财政分权程度与我国的最大化经济增长相符。最后,对得出的统计结论进行了充分的解释。     

Delivering endogenous inertia in prices and output

This paper presents a DGE model in which aggregate price level inertia is generated endogenously by the optimizing behavior of price-setting firms. All the usual sources of inertia are absent here i.e., all firms are simultaneously free to change their price once every period and face no adjustment costs in doing so. Despite this, the model generates persistent movements in aggregate output and inflation in response to a nominal shock. Two modifications of a standard one-quarter pre-set pricing model deliver these results: learning-by-doing and habit formation in leisure. While the model delivers persistence, simulations based on estimated shocks to tfp and money growth suggest both output and inflation are too volatile relative to the data and fail to closely follow the historical time series.
