Market penetration by entry-exit dynamics

A generic characterization of the dynamics of market penetration by technological artifacts is here formulated on the basis of entry rate and exit rate considerations. It is shown that low-order reductions lead to the biologically based logistic dynamic, which—by empirical fit—has been found to be in very good agreement with numerous specific cases. In addition to the derivational justification of the logistic for artifact market penetration, we find that but a small number of parameters are involved in these autonomous characterizations suggesting therefore that market penetration may well be reduced to a similarly small number of dominant operative processes. Some nonautonomous extensions are also discussed.     

The Home Bias in Equities and Distribution Costs

We show that incorporating distribution costs into a general equilibrium model of international portfolio choice helps to explain the home bias in international equity investment. Our model is able to replicate observed investment positions for a wide range of parameter values, even if agents have an incentive to hedge labor income risk by purchasing foreign equity. This is because the existence of a retail sector affects both the correlation of domestic returns with the domestic price level and the correlation between financial and non‐financial income.     

Antecedents and consequences of effectuation and causation in the international new venture creation process

The selection of the entry mode in an international market is of key importance for the venture. A process-based perspective on entry mode selection can add to the International Business and International Entrepreneurship literature. Framing the international market entry as an entrepreneurial process, this paper analyzes the antecedents and consequences of causation and effectuation in the entry mode selection. For the analysis, regression-based techniques were used on a sample of 65 gazelles. The results indicate that experienced entrepreneurs tend to apply effectuation rather than causation, while uncertainty does not have a systematic influence. Entrepreneurs using causation-based international new venture creation processes tend to engage in export-type entry modes, while effectuation-based international new venture creation processes do not predetermine the entry mode.     

Entrepreneurial Marketing: Geringer Mitteleinsatz mit hoher Wirkung

Entrepreneurial Marketing (EM) will dem schwindenden Einfluss klassischer Medien entgegentreten. Bei den Konsumenten soll ein glaubwürdiges, anschlussf?higes Produktimage ankommen. So baut EM auf unkonventionelle Ma?nahmen zur Erzeugung von Aufmerksamkeit (Buzz Marketing), die exponentielle Diffusion von Kommunikationsinhalten (Viral Marketing), die Nutzung von Communities (Community Marketing) oder die (Aus-)Nutzung der Marketingma?nahmen der Konkurrenz (Ambush Marketing), und versucht, mit geringem Mitteleinsatz hohe Wirkungen zu erzielen (Guerilla Marketing).     

The persistence of government expenditure shocks and the effect of monopolistic competition on the fiscal multiplier

In this paper, we demonstrate that the influence of monopolisticcompetition in the product market on an economy's impact responseto fiscal shocks depends on the persistence of these shocks.While short-lived increases in lump-sum financed governmentexpenditure have a stronger effect on labor supply if pricesare above marginal costs, the response of employment decreasesin the markup if shocks are highly persistent. However, we alsoshow that, while the impact response of labor supply to temporarygovernment expenditure shocks may be reduced by monopolisticcompetition, the fiscal multiplier is always higher if firmshave market power.     

Poverty and Political Risk

The paper explains the negative correlation between developing countries' per capita incomes and measures of political risk by relating a government's decision to tax foreign investors to distributional interests in the host country's population. Using a dynamic general-equilibrium model in which agents make irreversible investments abroad to insure against country-specific technology shocks, it is shown that the political risk for foreign investors is prohibitive if the host country's initial per capita income is too low and if the benefits of international diversification are not high enough to generate a sufficiently strong opposition against discriminatory taxation.     

Consistent recalibration of yield curve models

The analytical tractability of affine (short rate) models, such as the Vasi?ek and the Cox–Ingersoll–Ross (CIR) models, has made them a popular choice for modeling the dynamics of interest rates. However, in order to properly account for the dynamics of real data, these models must exhibit time‐dependent or even stochastic parameters. This breaks their tractability, and modeling and simulating become an arduous task. We introduce a new class of Heath–Jarrow–Morton (HJM) models that both fit the dynamics of real market data and remain tractable. We call these models consistent recalibration (CRC) models. CRC models appear as limits of concatenations of forward rate increments, each belonging to a Hull–White extended affine factor model with possibly different parameters. That is, we construct HJM models from “tangent” affine models. We develop a theory for continuous path versions of such models and discuss their numerical implementations within the Vasi?ek and CIR frameworks.     

Financial integration in autocracies: Greasing the wheel or more to steal?

This paper analyzes the influence of financial integration on institutional quality. We construct a dynamic political-economic model of an autocracy in which a ruling elite uses its political power to expropriate the general population. Although financial integration reduces capital costs for entrepreneurs and thereby raises gross incomes in the private sector, the elite may counteract this effect by increasing the rate of expropriation. Since de facto political power is linked to economic resources, financial integration also has long run consequences for the distribution of power and for the rise of an entrepreneurial class.
