BACKGROUND:Diagnosis of Pneumocystis jirovecii (PJ) pneumonia ordinarily requires invasive procedures that could be avoided by PCR methodologies, if these could be designed with adequate cut-off values for confounding background carriage. METHODS:We

This paper compares the Allowance for Corporate Equity (ACE) tax and the Comprehensive Business Income Tax (CBIT) in a general equilibrium model with firms that face entry costs, fixed production costs and increasing marginal costs. We add the empiri

The present paper explores how foreign business conditions affect domestic income, welfare, and industry structure, i.e., the international spillovers from business conditions, in a two-country one-sector heterogeneous-firms trade model. Pro-competit

The Landau–Lifshitz (LL) equation has been proposed as the classical equation to describe the dynamics of a charged particle in a strong electromagnetic field when influenced by radiation reaction. Until recently, there has been no clear experiment

Physical Review
An accelerated charged particle emits electromagnetic radiation. If the driving force is sufficiently strong, the radiated energy becomes comparable to the kinetic energy of the particle and the back-action of the emitted radiation (radiation reactio

This paper provides new evidence on how export status relates to prices and product quality. Using firm-product-level data on production, exports and imports for a sample of Danish manufacturing firms, we present three key correlations. First, export

Publicly funded/subsidized export promotion agencies reducing informational barriers to export and thus firm‐level fixed/sunk costs of exporting are present in most countries. This paper develops a two‐country one‐sector heterogeneous firms mod

Two decades of research have established pronounced exporter productivity premia (EPP) and exporter size premia (ESP). Yet, we do not know why such exporter premia differ so widely in magnitude across countries or sectors? We take this question to th
