Are expansions cost effective for stock exchanges? A global perspective

This paper investigates the existence and extent of economies of scale and scope among the stock exchanges. Evidence from 38 exchanges in 32 countries and 4 continents around the world for the years 1989–1998 portrays the existence of significant economies of scale and scope. The degree of such scale and scope however differs across size and regions. The largest exchanges show an increasing trend of cost effectiveness. The exchanges in North America and Europe report substantially higher economies of scale relative to the exchanges in the Asia-Pacific regions.     

The two faces of Nordic management? Nordic firms and their employee relations in the Baltic States

This study examines Nordic management styles in union and non-union industrial enterprises in the Baltic States (Estonia, Latvia, Lithuania) through case studies of nine Nordic subsidiary companies, based on on-site interviews with management and employees.1 1. Here, I refer to ‘Nordic’ countries denoting Denmark, Finland and Sweden, for the companies chosen for research are from these three countries and for the sake of common social and economic characteristics among these three countries, basing on the varieties of capitalism (VoC) literature. That is why Norway, a country seen usually in the composition of the Nordic countries, is left out of this investigation. The entity ‘Baltic States’ or ‘Baltic countries’ refers here to the three countries on the eastern shore of the Baltic Sea: Estonia (population 1.4 million), Latvia (2.3 million) and Lithuania (3.4 million). This analysis construes the ‘Nordic model’ of management style as ‘bargained constitutional’ or ‘sophisticated consultative’, following Purcell and Ahlstrand's (1994) matrix of management styles in the highly unionized countries of origin, characterized as coordinated market economies. The case studies reveal that in the Baltic liberal-market environment, Nordic employers exhibit a variety of management styles, ranging from sophisticated human relations or paternalistic relations styles in non-union contexts, to an adversarial bargained style or modern paternalistic style in unionized subsidiary firms. The Nordic model's ‘bargained constitutionalism’ only occurs in those cases in the sample in which Soviet-era trade union structures survive, or where an in-firm union has fought for recognition and collective bargaining.     

Renewable Resource Use and Nonseparable Amenity Benefits

We incorporate amenity benefits into an overlapping generations model with a renewable resource as a factor of production, source of amenity benefits and store of value. Unlike the conventional renewable resource problems studied under the assumption of additive consumption and amenity benefits, we let amenity benefits affect the utility of consumers in a nonseparable fashion. We examine the role that weights given to consumption and amenities have for harvesting and the resource stock. We characterize dynamics and stability of steady state equilibria with a logistic resource growth function. We demonstrate in parametric and numerical models that the weights given to consumption and amenities in the utility function matter substantially for the steady state equilibrium stock and its stability and dynamics. Both conventional saddle point equilibria and indeterminacy with infinite number of equilibria and saddle-node bifurcation is possible depending on the weights given to consumption and amenities. In addition, we show that for each inefficient equilibrium stock, there is a unique subsidy rate that can move the economy from an inefficient equilibrium to an efficient one. The presence of indeterminacy provides a challenge to resource policies, because the system becomes unpredictable. Therefore, expectations and market psychology may play an important role in resource utilization and provision of amenities.     

Modeling the U.S. Short-Term Interest Rate by Mixture Autoregressive Processes

A new kind of mixture autoregressive model with GARCH errorsis introduced and applied to the U.S. short-term interest rate.According to the diagnostic tests developed in the article andfurther informal checks, the model is capable of capturing bothof the typical characteristics of the short-term interest rate:volatility persistence and the dependence of volatility on thelevel of the interest rate. The model also allows for regimeswitches whose presence has been a third central result emergingfrom the recent empirical literature on the U.S. short-terminterest rate. Realizations generated from the estimated modelseem stable and their properties resemble those of the observedseries closely. The drift and diffusion functions implied bythe new model are in accordance with the results in much ofthe literature on continuous-time diffusion models for the short-terminterest rate, and the term structure implications agree withhistorically observed patterns.     

Corporate venture capital and the balance of risks and rewards for portfolio companies

This paper contributes to the literature on corporate venture capital (CVC) by examining the management of CVC investments from the perspective of the investee firm. We focus on the trade-off between social interactions and relationship safeguards and examine their effects on the twin relationship outcomes of learning benefits and risks. The model is tested using data collected from CEOs of U.S. technology-based new firms receiving CVC funding. Complementarities between the investee firm and its CVC investor are positively related to the level of social interaction and negatively related to the use of different types of relationship safeguards by the investee firm. The use of safeguards is further negatively related to both realized relationship risks and social interaction. Social interaction is positively related to realized learning benefits. These findings highlight the fine balance that the investee firm has to strike between openness and self protection in a CVC relationship. Implications for future research and current practice are discussed.     

Data-driven optimization of peer-to-peer lending portfolios based on the expected value framework

In recent years, peer-to-peer (P2P) lending has been gaining popularity amongst borrowers and individual investors. This can mainly be attributed to the easy and quick access to loans and the higher possible returns. However, the risk involved in these investments is considerable, and for most investors, being nonprofessionals, this increases the complexity and the importance of investment decisions. In this study, we focus on generating optimal investment decisions to lenders for selecting loans. We treat the loan selection process in P2P lending as a portfolio optimization problem, with the aim being to select a set of loans that provide a required return while minimizing risk. In the process, we use internal rate of return as the measure of return. As the starting point of the model, we use machine-learning algorithms to predict the default probabilities and calculate expected values for the loans based on historical data. Afterwards, we calculate the distance between loans using (i) default probabilities and, as a novel step, (ii) expected value. In the calculations, we utilize kernel functions to obtain similarity weights of loans as the input of the optimization models. Two optimization models are tested and compared on data from the popular P2P platform Lending Club. The results show that using the expected-value framework yields higher return.     

Agri‐environmental auctions for phosphorus load reduction: experiences from a Finnish pilot

We examine environmental auctions on working agricultural lands. We organized a discriminatory auction where farmers were asked to make bids on spreading gypsum on their fields to reduce phosphorus loads to surface waters. The parcel‐specific bids were ranked based on their load reduction–compensation ratios. To assess load reductions, we built an environmental benefit index (EBI) based on three factors: P‐status of the soil (phosphorus available for crops), field slope and location with respect to waterways. As the per tonne price of gypsum delivery from the factory was higher for small quantities, the auction format allowed bundling of field parcels to reduce transportation costs. We evaluate auction's ability to target the environmental (or abatement) measures to field parcels with the highest load reduction potential and analyse the economic efficiency of the auction by comparing the pilot auction with simulated bidding behaviour and with hypothetical flat rate payment schemes. The pilot auction targeted the environmental measures effectively. It was also more efficient than a flat rate payment, even when the flat rate scheme was combined with an EBI eligibility criterion.     

Labor or consumption taxes? An application with a dynamic general equilibrium model with heterogeneous agents

This study analyzes the effects of tax reform that shifts tax burden from labor to consumption. In this context, I also deal with the issue of progressivity. Even though this kind of tax policy change has recently gained popularity, its positive effects are debatable while the offsetting effect of a consumption tax on labor supply makes the net output change rather ambiguous. I examine these effects using a dynamic general equilibrium model with heterogeneous agents. The model is calibrated to fit certain characteristics of the Finnish economy. In addition to output and employment effects, I study the tax reform's effect on income and wealth distribution. First, I find that eliminating progressivity in labor taxation increases output via increase in capital accumulation that comes, however, in expense of slightly more inequality. Then, tax reform that replaces progressive labor taxes with a flat-rate consumption tax leads to a significant rise in capital accumulation, a negligible change in labor supply and gross labor income distribution, but a relatively considerable increase in wealth concentration.     

Landowners’ conservation motives and the size of information rents in environmental bidding systems

We examine landowners’ conservation motives, conservation costs and information rents in environmental bidding systems designed for forestry with the help of Faustmann and Hartman models and data from Finnish conservation program. We show that the Faustmann landowners receive information rents, on average 55% of the rental payments. For the Hartman landowners the high conservation costs of old stands result in low information rents; they are only 13% of the rental payments. This estimate omits amenity benefits the landowners derive from their forests; accounting for these benefits would increase information rents dramatically. Despite the high information rents, landowners’ conservation motives decrease the rental payment required for participation in the conservation program. Hence, landowners’ conservation motives give governments a great opportunity to allocate conservation contracts in a more cost effective way, thereby extracting larger benefits for scarce conservation funds.
