Lumpy Investment,Lumpy Inventories

The link between the microenvironment (frictions and heterogeneity) and the macroeconomic dynamics of general equilibrium macromodels is influenced by exactly how general equilibrium closes the model. We make this observation concrete using the recent literature on how nonconvex capital adjustment costs influence aggregate investment dynamics. We introduce inventories into a two‐sector lumpy investment model and find that nonconvex capital adjustment costs dampen and propagate investment impulse responses, more so than without inventories. With two means of transferring consumption into the future, fixed capital and inventories, the tight link between aggregate saving and fixed capital investment is broken.     

Housing and Tax Policy

This paper investigates the effects of housing‐related tax policy measures on macroeconomic aggregates using a dynamic general‐equilibrium model featuring borrowing and lending across heterogeneous households, financial frictions in the form of collateral constraints tied to house prices, and a rental housing market alongside owner‐occupied housing. We analyze the effects of various tax policies and find that they all lead to significant output losses, with large long‐run tax multipliers of around 2. Among them, reducing the mortgage interest deduction is the most effective in raising tax revenue per unit of output lost, whereas reducing the depreciation allowance for rental income is the least effective.     

Tax Evasion,Investment Shocks,and the Consumption Puzzle: A DSGE Analysis with Financial Frictions

Recent studies identify Marginal Efficiency of Investment (MEI) shocks as important drivers of the business cycle. However, Dynamic Stochastic General Equilibrium (DSGE) models struggle to explain macroeconomic comovements between consumption and the key real variables after a MEI shock. Moreover, engaging in tax evasion practices is often an answer to financial constraints, which have been recognized as important determinants of cyclical fluctuations as well. We use a medium-scale New Keynesian DSGE model, that combines tax evasion with financial frictions, to simulate a MEI shock. We show that entrepreneurial tax evasion can solve the comovement problem to a fair extent.     

运用税收政策提升居民储蓄存款的投资、消费转化率

随着分配格局的变化,我国越来越表现出明显的“超储蓄”现象。“超储蓄”现象的成因有两个方面:一是国家的保障制度还不够健全;二是投资和消费的安全性不够、动力不足。要促使储蓄转化为投资和即期消费,主要可以通过部分修改税法、开征个人财产税、开征社会保障税和调整个人所得税等税收政策来完成。     

Land Tax Changes and Full Capitalisation

We use a unique data set to examine the extent to which changes in the Danish land tax are capitalised into house prices. The Danish local government reform in 2007, which caused tax increases in some municipalities and tax decreases in others, provides plenty of exogenous variation, thus eliminating endogeneity problems. The results imply full capitalisation of the present value of future taxes under reasonable assumptions about discount rates. Consequently, the paper gives an empirical confirmation of two striking consequences of a land tax. First, it does not distort economic decisions because it does not distort the user cost of land. Second, the full incidence of a permanent land tax change lies on the owner at the time of the (announcement of the) tax change; future owners, even though they officially pay the recurrent taxes, are not affected as they are fully compensated via a corresponding change in the acquisition price of the asset.     

Determinacy under Inflation Targeting Interest Rate Policy in a Sticky Price Model with Investment (and Labor Bargaining)

In a sticky price model with investment spending, recent research shows that inflation-forecast targeting interest rate policy makes determinacy of equilibrium essentially impossible. We examine a necessary and sufficient condition for determinacy under interest rate policy that responds to a weighted average of an inflation forecast and current inflation. This condition demonstrates that the average-inflation targeting policy ensures determinacy as long as both the response to average inflation and the relative weight of current inflation are large enough. We also find that interest rate policy that responds solely to past inflation guarantees determinacy when its response satisfies the Taylor principle and is not large. These results still hold even when wages and hours worked are determined by Nash bargaining.     

The Stability of Tax Elasticities over the Business Cycle in European Countries

We estimate short‐ and long‐run tax elasticities that capture the relationship between changes in national income and tax revenue. We show that the short‐run tax elasticity changes according to the business cycle. We estimate a two‐state Markov‐switching regression on a novel data set of tax policy reforms in 15 European countries from 1980 to 2013, showing that the elasticities during booms and recessions are statistically (and often economically) different. The elasticities of personal income taxes, corporate income taxes, indirect taxes and social contributions tend to be larger during recessions. Estimates of long‐run elasticities are in line with existing literature.     

Corporate Tax Consolidation and Enhanced Cooperation in the European Union*

We assess the economic impact of introducing consolidation with formula apportionment in the European Union and consider alternative enhanced cooperation agreements. We find that the consolidation is likely to yield a small aggregate welfare gain in Europe. However, not all countries benefit. A coalition of winning countries reduces the welfare gain and may induce a process of adverse selection which destroys the possibility of cooperation. We find that a coalition of similar countries (in terms of the size of their multinational sector) is more feasible in achieving agreement and is actually preferred by those countries over a Europe‐wide reform.     

The Taylor Rule and “Opportunistic” Monetary Policy

We investigate the possibility that the Taylor rule should be formulated as a threshold process such that the Federal Reserve acts more aggressively in some circumstances than in others. It seems reasonable that the Federal Reserve would act more aggressively when inflation is high than when it is low. Similarly, it might be expected that the Federal Reserve responds more to a negative than a positive output gap. Although these specifications receive some empirical support, we find that a modified threshold model that is consistent with “opportunistic” monetary policy makes significant progress toward explaining Federal Reserve behavior.     

Macro‐Fiscal Volatility and the Composition of Public Spending*

Earlier empirical literature has examined some long‐ and medium‐term aspects of macro‐fiscal volatility while leaving its short‐term fiscal impact unexplored. To help fill that gap, we examine the impact of macro‐fiscal volatility on the composition of public spending. To that end, we analyse a panel of 10 EU countries during 1991–2007. Our results suggest that increases in the volatility of regularly‐collected and cyclical revenues such as the VAT and income taxes tend to tilt the expenditure composition in favour of public investment. In contrast, increases in the volatility of ad hoc taxes such as capital taxes tend to favour public consumption spending, albeit only a little. We interpret such volatility innovations as conveying news to the fiscal policymaker about the underlying economic conditions, with especially regularly‐collected and cyclical taxes prompting short‐term cyclical fine‐tuning.     

The Dynamics of Gasoline Prices: Evidence from Daily French Micro Data

Using millions of individual gasoline prices collected at a daily frequency, we examine the speed at which market prices of refined oil are transmitted to retail gasoline prices in France. For that, we estimate a reduced‐form model of state‐dependent pricing where thresholds triggering price changes are allowed to vary over time and depend on the duration since the last price change. We find that the degree of pass‐through of wholesale prices to retail gasoline prices is on average 0.77 for diesel and 0.67 for petrol and depend on local market characteristics. The duration for a shock to be fully transmitted into prices is about 10 days. There is no significant asymmetry in the transmission of wholesale price to retail prices. Finally, the duration since the last price change has a significant effect on thresholds triggering price changes but a large variance of idiosyncratic shocks on thresholds is also crucial to replicate the size distribution of price changes.     

Irreversible investment and industry equilibrium

We establish the equivalence of competitive industry equilibrium with a central planner's decision problem under uncertainty, when investment is irreversible. The existence of industry equilibrium is derived, and it is shown that myopic behavior on the part of small agents is harmless, in the sense that it leads to the same decisions as full rational expectations do. Our model is set in continuous time and allows for very general forms of randomness. The methods are based on the probabilistic approach to singular stochastic control theory and its connections with optimal stopping problems.
