Ownership Concentration and Share Valuation

Abstract. Concentrated ownership of large listed companies is widespread throughout the world, and Germany is typical in this respect. This paper proposes a method of distinguishing empirically between the beneficial and harmful effects of ownership concentration, and applies it to German data. The results show that, for most types of largest shareholder, the beneficial effects on minority shareholders of increased ownership (greater monitoring of management, and reduced incentives to exploit minority shareholders due to greater cash‐flow rights) are at least as large as, and sometimes significantly larger than, the harmful effect (greater private benefits of control due to greater control rights).     

Crop Price and Risk Effects on Farm Abatement Costs

Potential leaching losses of nitrogen depend in large part on the crops grown. Since crop selection is a major means of abatement for nitrates in groundwater, it follows that the compliance costs to producers for reducing excess nitrogen is influenced by crop prices. This paper demonstrates the role that crop prices play in determining the level of on-farm abatement costs and even the necessity for regulatory policies to deal with the nitrate problem. Government support programs, specifically the Gross Revenue Insurance Program (GRIP), have increased the relative support for corn, which has higher leachate potential than other crops, and thereby requires increased abatement effort. The required level of abatement is less when risk aversion is considered than under risk neutrality, since the variability in returns among rotations is related to the degree of emissions generated. Changes in the mean and variance of relative output prices can significantly alter the optimal crop mix, leachate potential and on-farm abatement efforts. Subsequently, there is an effect on abatement costs associated with alternative environmental control instruments, which in turn affects policy design through issues such as political feasibility and equity considerations.     

Farm share of the food dollar: an IO approach for the United States and Canada

This article develops a method for using input–output data to calculate a farm share estimate for all food rather than the typical approach of estimating a price spread for an individual product. The farm share of the food dollar is approximately 14% in the United States and 17% in Canada. The farm share increased somewhat during the commodity price boom but has generally fallen steadily by approximately 20% since 1997. While the farm share of expenditures on food for home consumption is approximately 22% across both countries, it is 4% in the United States and 7% in Canada for meals consumed away from home. The empirical framework can be extended to other countries given the extensive use of System of National Account data making international and temporal comparisons possible across farm and food marketing systems.     

Measuring Excess Capital Capacity in Agricultural Production

We introduce the concept "excess capital capacity" and employ a stochastic input requirement frontier to measure excess capital capacity in agricultural production. We also propose a two-step estimation method that allows endogenous regressors in stochastic frontier models. The first step uses generalized method of moments to get consistent estimates of the frontier parameters in the presence of endogenous regressors. The second step uses maximum likelihood to measure excess capital capacity and evaluate the factors that influence it. The empirical application to Dutch cash crop farms found varying degrees of excess capital capacity. The policy implications of excess capital capacity are discussed.     

Costs and benefits of controlling quarantine diseases: a bio-economic modeling approach

This article describes a bio-economic model to quantify the costs and benefits of controlling plant quarantine diseases. The model integrates the epidemiology and economic consequences of a quarantine disease. It allows for ex ante evaluation of control scenarios for their cost-effectiveness, taking into account potential export losses resulting from presence of the disease. The model is applied to brown rot of potato in the Dutch potato production chain. Simulation results show that under the current (2006) control policy, the average yearly costs of brown rot are 7.7 million euros. Reducing monitoring frequency increases the costs to 12.5 million euros, 60% of which are export losses. It is also shown that, due to potential long-term effects of a strategy, conclusions on cost-effectiveness of a strategy depend on the length of the period over which that strategy is observed. These applications illustrate the potential of the bio-economic model to facilitate the development of cost-effective and soundly based control policies.     

A multi-level and multi-actor approach to risk governance: a conceptual framework to support policy development for Ambrosia weed control

Invasive species such as Ambrosia (an annual weed) pose a biosecurity risk whose management depends on the knowledge, attitudes and practices of many stakeholders. It can therefore be considered a complex policy and risk governance problem. Complex policy problems are characterised by high uncertainty, multiple dimensions, interactions across different spatial and policy levels, and the involvement of a multitude of actors and organisations. This paper provides a conceptual framework for analysing the multi-level and multi-actor dimensions of Ambrosia management. Potential and existing public, private and public–private management strategies are identified to address the interests and needs of different actor groups across different levels. We conclude that policies that promote a mix of public and private Ambrosia management strategies may respond better to the needs and interests of different actor groups across different levels than a one-size-fits-all approach. However, multiple policy strategies need to be aligned in order to lead to synergies and spreading coherent messages to the public. Collaboration may enhance the likelihood of biosecurity management and risk governance of Ambrosia being adequately implemented and enforced.     

Fiscal federalism in monetary unions: hypothetical fiscal transfers within the Euro-zone

Net fiscal transfers are commonly seen as a possible means to ensure the well-functioning of a currency area. We show that US net fiscal transfers, measured as the difference between gross federal revenues and federal expenditures per state, are enormous. Moreover, we run panel regressions that suggest their dependence on relative GDP and relative GDP growth during crisis periods, evidence of net fiscal transfers from relatively rich to relatively poor states (redistributive effect) and to states with an underperforming economic development (stabilization effect). The Euro-zone (EZ) lacks a system of fiscal federalism, which raises the question of whether it should be established in the medium- and long-run. If so, which should be the magnitude of net fiscal transfers? We calculate these transfers hypothetically for 1999–2010, using a relative volume comparable to the one in the USA.     

Skating on thin ice: rule changes and team strategies in the NHL

Abstract.  In an effort to stimulate a more exciting and entertaining style of play, the National Hockey Association (NHL) changed the rewards associated with the results of overtime games. Under the new rules, teams tied at the end of regulation both receive a single point, regardless of the outcome in overtime. A team scoring in the sudden-death 5-minute overtime period would earn an additional point. Prior to the rule change in the 1999–2000 season, the team losing in overtime would receive no points while the winning team earned 2 points. This paper presents a theoretical model to explain the effect of the rule change on the strategy of play during both the overtime period and the regulation time game. The results suggest that under the new overtime, format equally powerful teams will play more offensively in overtime resulting in more games decided by a sudden-death goal. The results also suggest that while increasing the likelihood of attacking in overtime, the rule change would have a perverse effect on the style of play during regulation by causing them to play conservatively for the tie. Empirical data confirm the theoretical results. The paper also shows that increasing the rewards to a win in regulation time would prevent teams from playing defensively during regular time.     

Pricing Weather Insurance with a Random Strike Price: The Ontario Ice-Wine Harvest

Weather insurance within the agricultural sector has been limited by the difficulty in defining the appropriate weather event and in pricing the product. We develop a new pricing method for weather insurance under situations where returns depend not only on the occurrence of the weather event, but also its timing. The method is used to price weather insurance for ice wine. Because the harvest quantity of grapes for ice wine degrades over time, the strike value on the weather event measured as harvestable hours is random. We develop a Monte Carlo method to estimate the premium.
