Empirical evidence shows that innovative firms are often more constrained in obtaining external funds than less innovative firms. Explanations are based on the uncertain outcome and high costs of R&D effort. When providing credit, the lender assesses the creditworthiness of the borrower. She...

We study an economy with a high degree of financialization in which (non-financial) firms need loans from commercial banks to finance production, service debt, and make long-term investments. Along the business cycle, the economy follows Minskyan dynamics with firms traversing various stages of...

This paper combines horizontal and vertical innovations to build an endogenous growth model that allows for structural change. Older technologies are continuously replaced by newer ones due to creative destruction and new technologies appear as a result of horizontal innovations and as a result...

Firms often rely on external financing in order to conduct R&D. We ask to what extent discriminatory behaviour of the funds provider affects the industry evolution. The model is based on an evolutionary framework by Nelson and Winter. A firm chooses the amount of its R&D spending in an adaptive...

In this paper, we analyze optimal foreign direct investment of a firm which operates in a duopolistic market. We characterize a technology spillover threshold and show that for an intensity of spillovers below this threshold, there is a unique locally asymptotic stable steady state with a...

In this paper we present an inter-temporal optimization problem of a representative R&D firm that simultaneously invests in horizontal and vertical innovations. We posit that learning-by-doing makes the process of quality improvements a positive function of the number of existing technologies...

This paper establishes an agent-based model to describe the dynamic behaviour of the financial market with mutual fund managers and investors under two types of compensation contracts: asset-based fees and performance-based fees, and using two types of adaptive expectation: trend chaser and...

The total output of an economy usually follows cyclical movements which are accompanied by similar movements in stock prices. The common explanation relies on the demand side. It points out that stock market wealth drives consumption which triggers production afterwards. This paper focuses on...

In this paper we analyze an endogeneous growth model with human capital that results from public educational spending. We allow for public debt and analyze three different debt policies: a balanced government budget, a slight deficit policy where debt grows but less than GDP, and a strong...

Corruption in general and doping in particular are ubiquitous in both amateur and professional sports and have taken the character of a systematic threat. In creating unfair advantages, doping distorts the level playing field in sporting competition. With higher stakes involved, such distortions...
