The spatial structure of production with a Leontief technology

The structure of the optimal spatial pattern of production is studied when there are interdependencies among production units which can be described by a Leontief technology, and when there is a single marketplace of final demand, the CBD. Transportation cost is proportional to distance. It is shown that the various goods are produced in rings which can be ranked by distance from the CBD independently of the levels of final demand. Furthermore shipment of goods for meeting intermediate and final demand can only be in the direction of the CBD and no shipment of goods towards the periphery can occur. A finite algorithm is given for the construction of the optimal pattern and for determining a system of f.o.b. prices and land rents which sustain it as a competitive equilibrium.     

A Comparison of Two Quadratic Approaches to Hedging in Incomplete Markets

This paper provides comparative theoretical and numerical results on risks, values, and hedging strategies for local risk-minimization versus mean-variance hedging in a class of stochastic volatility models. We explain the theory for both hedging approaches in a general framework, specialize to a Markovian situation, and analyze in detail variants of the well-known Heston (1993) and Stein and Stein (1991) stochastic volatility models. Numerical results are obtained mainly by PDE and simulation methods. In addition, we take special care to check that all of our examples do satisfy the conditions required by the general theory.     

A Microeconomic Approach to Diffusion Models For Stock Prices

This paper studies a class of diffusion models for stock prices derived by a microeconomic approach. We consider discrete-time processes resulting from a market equilibrium and then apply an invariance principle to obtain a continuous-time model. the resulting process is an Ornstein-Uhlenbeck process in a random environment, and we analyze its qualitative behavior. In particular, we provide simple criteria for the stability or instability of the corresponding stock price model, and we give explicit formulae for the invariant distributions in the recurrent case.     

Cooperative investments induced by contract law

I revisit the economic analysis of contract law for a setting of cooperative investments. While Che and Chung (1999) have shown that expectation damages perform rather poorly, I argue that this negative result follows from their implicit assumption of unilateral expectation damages. Yet the very nature of cooperative investments gives rise to the possibility that both parties may claim expectation damages. I show that such a regime of bilateral expectation damages provides the incentives for the first‐best solution even in a framework of binary choice where, for selfish investments, the traditional overreliance result would hold.     

Short and long-term interactions between venture capital returns and the macroeconomy: evidence for the United States

The main purpose of this paper is to empirically model the influence of macroeconomic and financial variables on the performance of risk capital in the US. We start our investigation using a static long-run equilibrium model. In contrast to previous studies, we analyze the effect of several factors simultaneously within the framework of a vector error correction model (VECM). This allows us to study short- and long-term interactions to overcome the problem of endogeneity, and to discover causal mechanisms. The results show that the value of venture capital investments is positively related to industrial production, the exit channel Nasdaq, and the long-term interest rate. However, the value of venture capital investments is negatively related to the short-term interest rate. According to the short-term dynamics, VEC Granger causality confirms that only industrial production influences venture capital performance, while venture capital returns Granger causes Nasdaq performance.     

Internationalization as an entrepreneurial process

When firms cross-borders it is, by definition, internationalization. We believe that often internationalization should be seen as either a by-product of a firm’s efforts to improve its position within its network or networks, or as the result of an entrepreneurial action. We consider three theoretical approaches as a starting point and breathe life into them with a rich case study. We suggest adjustments to Johanson and Vahlne’s business network internationalization process model, an update of the Uppsala internationalization process model, to emphasize the entrepreneurial aspects of the process.     

Do Alternative Real Estate Investment Vehicles Add Value to REITs? Evidence from German Open-ended Property Funds

Besides the more commonly used REITs, German investors can also invest in a lesser-known real estate vehicle, Open-ended Property Funds. OPFs are considered a compromise between listed and direct real estate investments. OPF fund managers generally provide daily (perfect) liquidity. However, if liquidity falls below 5%, share redemptions in these funds can be temporarily suspended for a period of up to two years. During this time, investors will only be able to sell shares on the secondary market (exchange), and are thus subject to significant liquidity risk. The objective of this paper is to analyze whether OPFs add value to investor portfolios above that provided by REITs. We show that OPFs have a diversification advantage over REITs in low-risk portfolios, despite their larger potential liquidity risk. REIT liquidity is comparable to that of ordinary common stock, but OPFs exhibit an average initial discount to funds’ NAV of about 6% when share redemptions are temporarily suspended. However, in the long-run, this potential redemption suspension does not negatively influence OPF performance (in case OPFs reopen again). This makes OPFs an attractive investment alternative to REITs for investors who have a high level of risk aversion and a long-term investment horizon, such as endowments, insurance companies, and pension funds.
