Abstract Background Domestication usually has negative effects on insect performance, especially when they are reared continuously for many generations. Rejuvenation can reduce the of domestication in parasitoid, Trichogramma brassicae Bezdenko (Hymenoptera: Trichogrammatidae) 30 generations (G) Sitotroga cerealella (Olivier) (Lepidoptera: Gelechiidae). Life table and parasitism parameters prim...

Business credit lags GDP growth by about one year. This contributes to high leverage during recessions and slow deleveraging. We show that a model in which firms use risky long-term debt replicates this adjustment of firm debt. In the model, slow-moving has important effects for real activity. High levels issued expansions are only gradually reduced recessions. generates an adverse feedback loo...

We show that sovereign debt impairments can have a significant impact on financial markets and real economies through a credit ratings channel. Specifically, we find that firms reduce their investment and reliance on credit markets due to a rising cost of debt capital following a sovereign rating downgrade. We identify these effects by exploiting exogenous variation on corporate ratings due to ...

A standard assumption of structural models of default is that firms assets evolve exogenously. In this paper, we document the importance of accounting for investment options in models of credit risk. In the presence of financing and investment frictions, firm-level variables which proxy for asset composition carry explanatory power for credit spreads beyond leverage. As a result, cross-sectiona...

We show that introducing an external capital market with information asymmetry into a product market model reduces opportunistic substitution of sub-standard goods and encourages producers to concentrate on long-run reputation building. We test this result with a laboratory experiment. We find that, when the problem of product market opportunism is moderate, i.e., reputation formation equilibri...

The paper explores factors that lead to accumulation or decumulation of firms’ cash reserves. In particular, we empirically examine whether additional future fixed capital and R&D investment expenditures induce firms to change their liquidity ratio while considering the role of market imperfections. Implementing a dynamic framework on a panel of US, UK and German firms, we find that firms in al...

This paper empirically examines the role of diversification in export markets on firm-level R&D activities taking account of the potential endogeneity in this relationship. We show that geographical sales diversification across different regions of the world induces UK firms to increase their R&D expenditures, as firms must innovate and develop new products to maintain a competitive edge over t...
