Licensing a new product with non-linear contracts

Abstract .  This paper looks at a situation where a licensor owns a patent on a technology that allows the production of a new good. The licensor seeks to license its innovation to a set of producers that differ according to their marginal cost of producing an existing good. We show that the licensor is able to obtain the profit a monopolist would achieve by producing the new good. The equilibrium licensing contract specifies both a fixed fee and a royalty scheme based on the production of a licensee.     

Sequential decisions with tests

We consider a principal-agent problem where the principal wishes to be endorsed by a sequence of agents, but cannot truthfully reveal type. In the standard “herding” model, the agents learn from each other's decisions, which can lead to cascades on a given decision when later agents' private information is swamped. We augment the standard model to allow the principal to subject herself to a test designed to provide public information about her type. She must decide how tough a test to attempt from a continuum of test types, which involves trading off the higher probability of passing an easier test against the greater impact from passing a tougher test. We find that the principal will always choose to be tested, and will prefer a tough test to a neutral or easy one.     

A dynamic analysis of the differential incidence of capital and labour taxes in a two-class economy

This paper studies a differential incidence model, where a rise in a capital tax is accompanied by a change in a labour tax to hold constant the per capita government revenue, in a two-class growing economy. The major concern is to analyse the conditions necessary for the burden of such a tax substitution to fall solely, partially, or inconsequentially on capitalists or workers. The results obtained indicate that a higher rate of capital tax tends to impose a greater burden on workers.     

Understanding Error Structures and Exploiting Panel Data in Meta-analytic Benefit Transfers

A regression meta-analysis is a statistical summary of results from a set of empirical studies. While, a meta-analysis is typically used to drawn inferences regarding the collective insights from an empirical literature, a regression meta-analysis can also be used to predict outcomes as a substitute for the conduct of a new study. Within the nonmarket-valuation literature benefit transfers are a special case of prediction where value estimates collected for one purpose are used as a basis for predicting value for unstudied applications. Balancing against the prediction opportunities provided by a regression meta-analysis is the potential prediction error. This paper considers some of these issues in the estimation of a regression meta-analysis to support prediction of nonmarket values for applications where an original study does not exist. We do not purport to address all elements of the error structure and prediction issues, but to present a more coherent focus to enhance future research on the validity and reliability of benefit-function transfers, and ultimately assist in enhancing the credibility of benefit transfers to support policy analyses.

Estimating global returns to scale with a cone-homogeneous production function: some cross-section results

This paper employs a cone-homogeneous production function to approximate, as closely as desired, a ray-homogeneous production function. Points in input space are projected by an output scaling function on to a fixed ray and a Cobb-Douglas cone function is used to obtain an estimate of global returns to scale. The empirical results indicate that we get a good approximation to a ray-homogeneous production function from the estimated cone-homogeneous function.     

Niche overlap and limiting similarity: an ecological approach to the theory of the firm

This paper suggests an approach, based upon an analogy with different species competing in the environment for fixed resources, to the question of why variety is such a persistent feature of free market economies. Attention is centred upon a market characterised by a group of consumers with a distribution of incomes, which leads to a continuum of demands for different output qualities. The identification of various sufficient conditions then allows the argument to proceed through a mathematical structure first outlined in the theoretical ecology literature, resulting in a precise prediction regarding the limit to similarity between firms. This results is then applied to the U.K. Supermarket industry in 1988, and is used to provide guidance to the state of competition within the industry in that year.     

Incentive Regulation of Prices When Costs are Sunk

We present a model featuring irreversible investment, economies of scale, uncertain future demand and capital prices, and a regulator who sets the firm’s output price according to the cost structure of a hypothetical replacement firm. We show that a replacement firm has a fundamental cost advantage over the regulated firm: it can better exploit the economies of scale because it has not had to confront the historical uncertainties faced by the regulated firm. We show that setting prices so low that a replacement firm is just willing to participate is insufficient to allow the regulated firm to expect to break even whenever it has to invest. Thus, unless the regulator is willing to incur costly monitoring to ensure the firm invests, revenue must be allowed in excess of that required for a replacement firm to participate. This contrasts with much of the existing literature, which argues that the market value of a regulated firm should equal the cost of replacing its existing assets. We also obtain a closed-form solution for the regulated firm’s output price when this price is set at discrete intervals. In contrast to rate of return regulation, we find that resetting the regulated price more frequently can increase the risk faced by the firm’s owners, and that this is reflected in a higher output price and a higher weighted-average cost of capital.     

Sustainability-oriented tax-based own resources for the European Union: a European carbon-based flight ticket tax

The failed attempts of several European countries to introduce a flight ticket tax and the pressure on those European Union Member States still levying such a tax clearly demonstrate the limits of national aviation taxation. Assigning a carbon-based flight ticket tax to the EU level would reduce the tax enforcement problems inherent to mobile tax bases and put a stop to harmful tax competition between EU Member States. By replacing a part of national contributions to the EU budget a flight ticket tax can strengthen sustainability-orientation of the EU system of own resources. Using a new data set, which assigns to approximately 75 to 90% of the respective intra and extra EU routes flown in the year 2014 the corresponding carbon emissions per passenger, the paper estimates the expected revenue from implementing a carbon-based flight ticket tax at the EU level for carbon tax levels between 25 and 35€ per ton of carbon emissions.     

Application of logistic analysis to the history of physics

Recently, two analyses have tried to put technological progress in a larger context. One interpretation hypothesizes that technological progress is likely to continue at increasingly higher rates of change. Another interpretation, which includes data from the beginning of the universe to the present, suggests that the universe is approaching a transition point in a logistic development of complexity. This logistic development is similar to the way ideas or products diffuse in a population, i.e., the rate of discovery in a field of knowledge is proportional to the amount discovered and the amount to be discovered. To test a part of this hypothesis, a leading indicator field (fundamental physics) was identified and the events in the history of this field were analyzed. Twelve subfields were identified and grouped into six stages. Each stage seemed to demonstrate a logistic-like development. By analyzing both the median time of development and the characteristic time of development of these stages, the overall development of this one field was found to suggest logistic development. These data seem to indicate that development in fundamental physics is slowing down, with at least one subfield beyond string physics yet to be developed. The data tend to support the hypothesis that a knowledge field can develop logistically.     

The meta-crisis of secular capitalism

The current global economic crisis concerns the way in which contemporary capitalism has turned to financialisation as a double cure for both a falling rate of profit and a deficiency of demand. Although this turning is by no means unprecedented, policies of financialisation have depressed demand (in part as a result of the long-term stagnation of average wages) while at the same time not proving adequate to restore profits and growth. This paper argues that the current crisis is less the ‘normal’ one that has to do with a constitutive need to balance growth of abstract wealth with demand for concrete commodities. Rather, it marks a meta-crisis of capitalism that is to do with the difficulties of sustaining abstract growth as such. This meta-crisis is the tendency at once to abstract from the real economy of productive activities and to reduce everything to its bare materiality. By contrast with a market economy that binds material value to symbolic meaning, a capitalist economy tends to separate matter from symbol and reduce materiality to calculable numbers representing ‘wealth’. Such a conception of wealth rests on the aggregation of abstract numbers that cuts out all the relational goods and the ‘commons’ on which shared prosperity depends.     

A game-theoretic model of coalition formation among primates

This paper models the coalition formation process among primates as a sequential game. The population consists of individuals having distinct social ranks which is determined by the individual’s resource holding potential. Each member of the population is interested in gaining access to a food resource, either individually or via a coalition. At any given stage of the game, a player can either propose a specific coalition or he can be proposed to in order to join one. Hence, the strategy of a player consists of a sequence of decisions regarding who to propose to for the formation of a coalition and which proposals to accept or reject. We derive the preferences of the players over the various coalition structures under the assumption that the probability of a coalition to obtain the resource is given by a logistic distribution as a function of relative strengths of the players. We show that, given the primates’ strategic behavior, a variety of different coalition structures can emerge in equilibrium.      

Who gets the goods? Moderate Voting Records,Diminishing Returns,and PAC Contributions

Assuming that a legislator representing a moderate constituency (with respect to a variety of interests) may be expected to vote moderately in general, the authors suggest a measure of the 'moderateness' of a legislator's voting behavior and use it to determine whether a relationship exists between PAC contributions and the degree of moderateness. The results suggest that PACs exhibit a tendency to give more, at the margin, to legislators with moderate voting records.     

Critical mass of users versus critical mass of services in a multiproduct information service system

In this paper we study the economic behaviour of the suppliers of a set of advanced telecommunications services with a joint adoption cost (common access facilities, learning process, etc.). In fixing the two-part tariffs for their services the suppliers have to share the burden of leaving to the users a surplus sufficient to cover the adoption cost. The lack of coordination in supplying a critical mass of services or in the pricing decisions has high changes to result in suboptimal or unviable diffusion of the new technology as a whole. We present a static optimization model of user behaviour, and derive access and usage demand with a two-part tariff and a joint adoption cost. We compare noncooperative and cooperative market equilibria in a duopoly with perfect information; finally we discuss the extension of our analysis to the case of imperfect information in a dynamic setting.     

Mechanism design with a liquidity constrained buyer: The 2×2 case

This paper studies the implications of buyers' liquidity constraints for the optimal selling strategy. The possibility that a buyer faces a binding liquidity constraint affects the seller's strategy in a nontrivial way. Specifically, when a seller has one unit of a good to sell to a buyer with a quasilinear utility function, the `no-haggling' result indicates that textbook monopoly pricing is optimal, absent liquidity constraints. Introducing a potentially binding liquidity constraint vitiates the no-haggling result, and can make it strictly beneficial for the seller to use nonlinear pricing, to commit to a declining price sequence, or to require the buyer to post a cash bond.     

Donor Altruism and the Transfer Paradox in an Overlapping Generations Model

This paper examines the transfer problem between two countries when a donor exhibits altruistic utility toward a recipient in a one‐sector overlapping generations model. We demonstrate that if the donor has a larger marginal propensity to save than the recipient, the donor's altruism never contributes to donor enrichment irrespective of the degree of the donor's altruism. Donor enrichment occurs only if the donor has a smaller marginal propensity to save and a sufficiently high level of altruism. These findings imply that the altruism of a donor toward a recipient does not necessarily explain the motivation to voluntarily provide a transfer.     

Targeting the biotechnology clusters in North Carolina and Israel: lessons from successful and unsuccessful policy making

This paper analyses the development of biotechnology clusters in North Carolina (NC) and Israel. In both NC and Israel, when the biotechnology was identified as a potential strategic priority, the framework conditions were suitable for successful policy-targeting. NC presents a case of a successful transition from a traditional manufacturing economy to a knowledge economy. The most successful part of this transition was a policy-led development of a biotechnology cluster in the Research Triangle. While Israel also presents a case of a successful transition from a low-tech economy to a knowledge-intensive economy, Israel failed to develop a successful biotechnology cluster. We suggest that this failure is mostly due to a failure to implement policy to encourage such development. We argue that the elements, which separate NC's success from Israel's failure, are: a clear vision and strategic planning; timely response, long-term commitment; strong leadership; cooperation between the government, private sector and academia, and an adjustable policy-making process.     

The value of nonindigenous species risk assessment in international trade

Managing the introduction of nonindigenous species is becoming a major goal of policy-makers at regional, national and international scales. Here we investigate, at the national level, the ideal design and expected net benefits of a risk assessment program for evaluating the desirability of nonindigenous species imports. We show how to enhance the statistical rigor of such a system by correcting a common non-random sampling problem encountered in the data. This correction enables model output to be interpreted in an economically relevant way and facilitates a theoretically rigorous characterization of the balance between trade and nonindigenous species establishment risk. Using reptiles and amphibians imported to the U.S. as a case study, we characterize economic outcomes over a range of cases and demonstrate substantial expected returns to such a screening program, relative to the current effectively open-door policy. Our results are informative for the current debate in the U.S. about whether to require federal agencies to apply risk assessment before allowing a species for import. The framework presented decomposes a complex argument about risk management into component economic and statistical parts, allowing for debate and improved understanding over each element to inform the overall program in a transparent fashion.     

Ex ante identification of disruptive innovations in the software industry applied to web applications: The case of Microsoft's vs. Google's office applications

This paper analyzes the question whether web applications pose a disruptive threat to incumbents or a disruptive growth opportunity for entrants in the application software industry using a novel method for ex ante identification of disruptive innovations in the software industry. Building on the theory of disruptive innovations, network effects and existing frameworks for the ex ante identification of disruptive innovations a new method of analysis is deduced. The analysis is based on a list of criteria that indicate a disruptive innovation and trajectory maps of the technologies' performance attributes. This method is applied to study the potential disruption of Microsoft's desktop office applications by Google's web-based office applications.The chosen method of analysis indicates a small likelihood for web applications to pose a disruptive threat to Microsoft, and by extension, to incumbents in the software industry. While web applications show a potential to satisfy market demand in established performance attributes, strong network effects in existing software products should give incumbents enough time to co-opt the innovation. The case illustrates how our new method to analyze disruptive potential in the software industry ex ante can help to apply the theory of disruptive innovation better for forecasting purposes and to provide novel strategic insights for the players involved.     

A Note on Inflation Targeting

The authors present a pedagogical graphical exposition to illustrate the stabilizing effect of price target zones. Based on a textbook AD-AS apparatus, they find that authorities' commitment to defend a price target zone will affect the public's inflation expectations and, in turn, reduce actual inflation. They also find that, when the economy experiences supply shocks, the announcement that the monetary authorities intend to defend a price target zone will reduce the variability of domestic prices but raise the variability of domestic output relative to a free-price regime. However, when the economy experiences demand shocks, a price target zone tends to lower the variability of both domestic prices and out-put relative to a free-price regime.
