Risk aversion and the dynamics of optimal liquidation strategies in illiquid markets

We consider the infinite-horizon optimal portfolio liquidation problem for a von Neumann–Morgenstern investor in the liquidity model of Almgren (Appl. Math. Finance 10:1–18, 2003). Using a stochastic control approach, we characterize the value function and the optimal strategy as classical solutions of nonlinear parabolic partial differential equations. We furthermore analyze the sensitivities of the value function and the optimal strategy with respect to the various model parameters. In particular, we find that the optimal strategy is aggressive or passive in-the-money, respectively, if and only if the utility function displays increasing or decreasing risk aversion. Surprisingly, only few further monotonicity relations exist with respect to the other parameters. We point out in particular that the speed by which the remaining asset position is sold can be decreasing in the size of the position but increasing in the liquidity price impact.      

Leapfrogging to Sustainable Consumption? An Explorative Survey of Consumption Habits and Orientations in Southern Brazil

In current political and scientific debates on sustainable consumption, the low- and middle-income classes of emerging countries are gaining attention. One common feature of such debates is the idea that these emerging consumer classes could be motivated to “leapfrog” directly to environmentally and socially aware consumption patterns and, thereby, avoid adopting the resource-intensive consumption styles of populations in industrialized countries. To be able to adapt sustainable product development or sustainable communication strategies to the needs of low- and medium-income classes, it is necessary to know more about the basic consumption orientations, current consumption habits, and future consumption aspirations of these societal groups. In order to contribute towards filling that knowledge gap, an exploratory survey was conducted, taking the example of emerging low- and middle-income classes in a Southern Brazilian city. The survey identified five different consumer types: the Home-Centered Traditionals, the Indifferent, the Up-to-date Privileged, the Wanna-be Materialists, and the Quality of Life-Oriented Postmaterialists. The paper outlines some ideas concerning how these types can be addressed with target-group-specific products and services as well as differentiated sustainability communication strategies. We conclude, however, that “leapfrogging” of Brazilian low- and middle-income classes towards sustainable consumption is not a very likely option. There are certain consumption orientations that sustainability strategies can link to, but these trends are not likely to compensate the general tendencies towards a resource-intensive lifestyle following the model of the industrialized countries.

Small business survival and inheritance: evidence from Germany

This paper investigates whether small businesses face financial constraints that affect their survival. A model of moral hazard is developed in which financial constraints arise endogenously. The model predicts that higher private assets relax financial constraints and have a positive effect on the firm’s probability of survival. The empirical analysis confirms that the entrepreneur has a higher propensity to stay in business when she inherits capital. This effect is particularly strong for entrepreneurs who switch from self-employment into wage employment.

Correcting for the Missing Rich: An Application to Wealth Survey Data

It is a well‐known criticism that if the distribution of wealth is highly concentrated, survey data are hardly reliable when it comes to analyzing the richest parts of society. This paper addresses this criticism by providing a general rationale of the underlying methodological problem as well as by proposing a specific methodological approach tailored to correcting the arising bias. We illustrate the latter approach by using Austrian data from the Household Finance and Consumption Survey. Specifically, we identify suitable parameter combinations by using a series of maximum‐likelihood estimates and appropriate goodness‐of‐fit tests to avoid arbitrariness with respect to the fitting of the Pareto distribution. Our results suggest that the alleged non‐observation bias is considerable, accounting for about one quarter of total net wealth in the case of Austria. The method developed in this paper can easily be applied to other countries where survey data on wealth are available.     

Business climate as a leading indicator? An empirical investigation for west Germany from 1978 to 1990

For twenty-five years now, the leading indicator “Business Climate” of the Ifo Institute has been applied in the Federal Republic of Germany. The intent of this note is to provide answers to two questions by means of econometric methods. The first question is: Is the business climate really a leading indicator? The second question is: How much time is the indicator ahead? For verification and in order to respond to both questions, the Granger causality test is used in the version of Hsiao.
