This paper develops and estimates a stochastic general equilibrium model with capital maintenance, which affects endogenously the depreciation rate of capital. The estimate of maintenance series is found to track survey-based measures for Canada quite closely and to generate the procyclical...

This paper studies optimal fiscal policy, in the form of taxation and the allocation of tax revenues between infrastructure and environmental investment, in a general-equilibrium growth model with endogenous subjective discounting. A green spending reform, defined as a reallocation of government...

Data published by the U.S. Congressional Budget Office show that over the last fifty years expenditures for infrastructure�s operations and maintenance (O&M) have roughly equalled those for new capital. We use this dataset to investigate the productive impact of public...

In this paper we estimate the single-factor Consumption Capital Asset Pricing Model (C-CAPM) over the frequency domain. We modify the standard two-step methodology (Fama and French, 1992) to account for the spectral properties of consumption risk and we find that its lower frequencies explain up...

This paper looks at the empirical consequences of introducing endogenous capital depreciation in the standard neoclassical model with quadratic adjustment costs. To this end, we formulate an empirical specification that accommodates capital maintenance and utilization in the Euler equations for...

Foreign aid flows have increased considerably during the last decades, targeting, apart from development objectives, goals related to democracy. In this paper we investigate whether aid has affected the political regime of recipient countries. To this end, we use annual data on Net Official...

Received wisdom suggests that �excessive� wages, defined as the part of real wages that do not follow labour productivity developments, are adversely associated with the return on capital. This paper argues that excessive wages and profits...

Statistical models are usually thought of as means for describing statistical regularities. Concerning stock returns, many empirical regularities have been documented in the literature together with their corresponding models. The main task of this paper is to investigate, under the prism of the...

The Single Factor Model (SFMT) of stock returns in its simplest form, namely the one that assumes time-invariant beta and homoskedastic error has been found to be empirically inadequate.The beta coefficient and the error process exhibit signi��cant time-variation and dynamic...

In this paper we investigate whether the empirical regularities of stock returns are independent of each other or whether any one of them implies all the others. If such a regularity exists, it is called 'fundamental' and is usually thought of as a 'deductive explanation' of the others. We...
