Whether or not the marginal product of capital (MPK) differs across countries is a question that keeps coming up in discussions of comparative economic development and patterns of capital flows. Using easily accessible macroeconomic data we find that MPKs are remarkably similar across countries. Hence, there is no prima facie support for the view that international credit frictions play a major...

This paper studies robust Ramsey policy problems in a general discrete-time linearquadratic framework when the Ramsey planner faces three types of ambiguity. This framework includes both exogenous and endogenous state variables. In addition, the equilibrium system from the private sector contains both backward-looking and forward-looking dynamics. We provide recursive characterizations and algo...

The aim of this work is to investigate the effects of different force fields and temperatures on the structural character of Aβ (12-28) peptide in aqueous solution. Moreover, the structural character of Aβ (12-28) peptide is compared with other amyloid peptides (such as H1 and α-syn12 peptide). The two independent temperature replica exchange molecular dynamics (T-REMD) simulations were complet...

We use a panel of over 120,000 Chinese firms of different ownership types over the period 2000-2007 to analyze the linkages between investment in fixed and working capital and financing constraints. We find that those firms characterized by high working capital display high sensitivities of investment in working capital to cash flow (WKS) and low sensitivities of investment in fixed capital to ...

This paper examines the effect of economic policy uncertainty and its components on firm-level investment. It is found that economic policy uncertainty in interaction with firm-level uncertainty depresses firms’ investment decisions. When firms are in doubt about costs of doing business due to possible changes in regulation, cost of health care and taxes, they become more guarded with investmen...

Labor’s share of GDP in most OECD countries has declined over the last two decades. Some authors have suggested that these changes are linked to deregulation of product and labor markets. To examine this we focus on a large quasi-experiment in the OECD: the privatization of many network industries (e.g. telecommunications and utilities). We present a model with agency problems, imperfect produc...

This paper studies the impact of corporate tax policy on the economy in the presence of both convex and nonconvex capital adjustment costs in a dynamic general equilibrium model. We show that corporate tax policy generates both intensive and extensive margin effects via the channel of marginal Q. Its impact is determined largely by the strength of the extensive margin effect, which in turn depe...

This paper studies conditions under which demand-side shocks can generate realistic business cycles in RBC models. Although highly persistent demand shocks are necessary for generating procyclical investment, variable capacity utilization and habit formation can reduce the required degree of persistence. Keywords: Demand Shocks; Hall’s Residual; Real Business Cycles; Crowding Out; Investment Dy...

One of the explanations for global imbalances is the self-financing behavior of credit-constrained firms in rapidly growing emerging markets. We use an extensive firm-level data set from several Asian countries during 2002–2011, and test the micro foundation of this theory by estimating the effect of an exogenous change in credit constraints, resulting from financial reforms, on firms’ saving b...

In the COVID-19 pandemic, people’s dwellings suddenly became a predominant site of economic activity. We argue that, predictably, policy-makers and employers took home for granted as background support life. Acting if is cost-less resource that free appropriation in an emergency, ignoring how functions gendered relations care labour, assuming largely harmonious site, all shaped invisibility imp...
