Patent pools,vertical integration,and downstream competition

Patent pools are commonly used to license technologies to manufacturers. Whereas previous studies focused on manufacturers active in independent markets, we analyze pools licensing to competing manufacturers, allowing for multiple licensors and nonlinear tariffs. We find that the impact of pools on welfare depends on the industry structure: whereas they are procompetitive when no manufacturer is integrated with a licensor, the presence of vertically integrated manufacturers triggers a novel trade‐off between horizontal and vertical price coordination. Specifically, pools are anticompetitive if the share of integrated firms is large, procompetitive otherwise. We then formulate information‐free policies to screen anticompetitive pools.     

Inflation targeting credibility and sovereign risk: evidence from Colombia

This article relates to the literature on sovereign risk in developing countries. In particular, we present empirical evidence to address the effect of inflation targeting credibility on sovereign risk based on the Colombian experience. The findings denote that credibility is an important improvement in the institutional framework to reduce the sovereign risk premium.     

Some new characterization of rational expectation equilibria in economies with asymmetric information

We compare the family of rational expectation equilibria with the ex-post Aubin core allocations in the framework of an economy with uncertainty and asymmetric information. We do it in a very general setting: an arbitrary space of agents and an infinite dimensional commodity space. We also present a characterization of the ex–post Aubin core by allocations belonging to the core of the associated complete information economies, and we use a suitable definition of Edgeworth equilibria to characterize the family of rational expectation equilibria. Moreover, we study some generalizations of the ex-post Aubin core obtained by making some restriction on the families of blocking coalitions.     

Bankruptcy law and corporate investment decisions

Major European countries have recently adopted bankruptcy codes that strengthen entrepreneurs’ power to renegotiate outstanding liabilities. Renegotiation in bankruptcy allows lenders to increase recovery rates, however it also weakens the contract’s ability to solve the moral hazard problem embedded in the production project. Hinging on this trade-off, I show in which circumstances a soft bankruptcy law that resembles Chapter 11 in the balance of lenders’ and entrepreneur’s rights encourages the choice of investments that privilege the achievement of long-term results. However, I also show that, in contrast to the common wisdom, soft bankruptcy can lead to the choice of investments that are biased towards the achievement of short-term outcomes.     

Driving under the influence of alcohol in Cali,Colombia: prevalence and consumption patterns, 2013

This study's goal was to establish the prevalence of driving under the influence of alcohol (DUI) and alcohol consumption patterns among drivers in Cali, Colombia, in 2013. A cross-sectional study based on a roadside survey using a stratified and multi-stage sampling design was developed. Thirty-two sites were chosen randomly for the selection of drivers who were then tested for blood alcohol concentration (BAC) and asked to participate in the survey. The prevalence of DUI was 0.88% (95% confidence intervals [95% CI] 0.26%–1.49%) with a lower prevalence when BAC was increasing. In addition, a higher prevalence was found during non-typical checkpoint hours (1.28, 95% CI ?0.001%–0.03%). The overall prevalence is considered high, given the low alcohol consumption and vehicles per capita. Prevention measures are needed to reduce DUI during non-typical checkpoints and ongoing studies are required to monitor the trends and enable the assessment of interventions.     

A simple model of vertical search engines foreclosure

By means of a simple model with consumers' search, the paper analyzes a monopolistic general search engine incentives to bias organic and sponsored search results in order to favor an integrated website. In the model, manipulation takes place whenever the general search engine places prominently its own vertical search engine instead of the most relevant for consumers. The main finding is that the incentives to manipulate search results are stronger in the organic search case. In the sponsored search case the general search platform internalizes the impact of manipulation on profits, since the less a prominent vertical search engine is relevant to consumers, the lower is the price-per-click that the general search engine can charge.     

Announcements credibility and government securities: evidence from Colombia

This article evaluates the effect of central bank announcements on government securities yields in emerging economy. In particular, based on the Colombian experience, we present empirical evidence to address the effect of credibility scenario in which the central bank announcements are made. The findings denote that credibility performance must be taken into account to verify the impact of monetary policy announcements.     

Demand and cost impacts of the 2 mm technology program in the US motor-vehicle market

We assess the impact on demand and producers’ costs of a new technology implemented in the US auto industry, the 2 mm program. This is a fascinating case partially because of the unique collaboration among public agencies and a consortium of manufacturers and universities. Using a type of hedonic price model for demand, we show that the new technology was responsible for a short-lived increase in demand for vehicles produced by US automakers at increased producers’ costs. Firms that refused to participate in the consortium attained smaller net gains implementing the technology independently. Overall, our approach differs from that of previous analysts in that we (1) separate demand from supply, (2) employ a comprehensive vehicle database, spanning 1981–1998 data, including data on virtually all vehicle models sold in the USA, as well as data on plants’ and producers’ technology characteristics, and (3) rely on sales and production data rather than plant data. Also, we quantify the cost of not participating in the consortium.     

Price Commitments in Standard Setting under Asymmetric Information*

Standards may create market power for the holders of standard essential patents (SEPs). To address these concerns, the literature advocates price commitments, whereby SEP holders commit to the maximum royalty they would charge were their technology included in the standard. We consider a setting in which a technology implementer holds private information about profitability. In this setting, price commitments increase efficiency not only by curbing SEP holders' market power, but also by alleviating distortions in the design of the royalty scheme. We derive conditions under which price commitments can be implemented using a simple royalty cap as used in practice.     

Vertical integration,foreclosure, and productive efficiency

We analyze the consequences of vertical integration by a monopoly producer dealing with two retailers (downstream firms) of varying efficiency via secret two‐part tariffs. When integrated with the inefficient retailer, the monopoly producer does not foreclose the rival retailer due to an output‐shifting effect. This effect can induce the integrated firm to engage in below‐cost pricing at the wholesale level, thereby rendering integration procompetitive. Output shifting arises with homogeneous and differentiated products. Moreover, we show that integration with an inefficient retailer emerges in a model with uncertainty over retailers' costs, and this merger can be procompetitive in expectation.
