Incentives to invest and to give access to non-regulated new technologies

We analyze the incentives of a vertically integrated firm, which is a regulated monopolist in the wholesale market and competes with an entrant in the retail market, to invest and to give access to a new wholesale technology. The new technology represents a non-drastic innovation that produces retail services of a higher quality than the old technology, and is left unregulated. We show that for intermediate values of the access price for the old technology, the vertically integrated firm may decide not to invest. When investment occurs, the vertically integrated firm may be induced to give access to the entrant for a low access price for the old technology. Furthermore, when both firms can invest, investment occurs under a larger set of circumstances, and it is the entrant the firm that invests in more cases. We also discuss the implications for the regulation of the old technology.     

Corruption and auctions

We investigate how corruption affects the outcome of a first-price auction (bidding behavior, efficiency and the seller’s expected revenue). The auctioneer approaches the winner to offer the possibility of a reduction in his bid in exchange for a bribe. The bribe can be a percentage of the difference between the winning and the second-highest bid or a fixed amount. We show that there exists a symmetric bidding strategy equilibrium that is monotone, i.e., higher valuation buyers bid higher. Corruption does not affect efficiency but both the auctioneer’s expected bribe and the seller’s expected revenue depend on the format of the bribe payments. We also find the optimal bribe scheme.     

Can People Value Protection against Invasive Marine Species? Evidence from a Joint TC–CV Survey in the Netherlands

Harmful algal-bloom species (HABs) are invasiveexotic species that are primarily introduced inNorth European waters through ballast water ofships. Some produce important damages to themarine ecosystem such as the red tides thatcause a massive destruction of marine livingresources, including fish and bottom-livinganimals. Others are responsible for theproduction of thick foams with repellent odorsand the coloration of the beach water, causingimportant damages on beach recreation. Thisarticle reports a monetary valuation study of amarine protection program. This program focuseson the prevention of HABS along the coastlineof the Netherlands. It entails the constructionof a ballast water disposal treatment in theRotterdam harbor and the implementationof a monitoring program of the water quality inthe open sea along the North-Holland beaches.The valuation study is based on a questionnaireundertaken at Zandvoort, a famous Dutchbeach resort. The economic value of the marineprotection program includes non-market benefitsassociated with beach recreation, human healthand marine ecosystem impacts. Both contingent-valuation and travel-cost methods are used.These valuation techniques have not yet beenapplied to value HABs damages. The valuationresults indicate that the protection programmakes sense from an economic perspective aslong as its cost is, in any case, less than 225 millioneuro, and possibly less than 326 million euro, depending on how survey refusals are dealt with.     

Synergies and price trends in sequential auctions

In this paper we consider sequential second-price auctions where an individual's value for a bundle of objects is either greater than the sum of the values for the objects separately (positive synergy) or less than the sum (negative synergy). We show that the existence of positive synergies implies declining expected prices. When synergies are negative, expected prices are increasing. There are several corollaries. First, the seller is indifferent between selling the objects simultaneously as a bundle or sequentially when synergies are positive. Second, when synergies are negative, the expected revenue generated by the simultaneous auction can be larger or smaller than the expected revenue generated by the sequential auction. In addition, in the presence of positive synergies, an option to buy the additional object at the price of the first object is never exercised in the symmetric equilibrium and the seller's revenue is unchanged. Under negative synergies, in contrast, if there is an equilibrium where the option is never exercised, then equilibrium prices may either increase or decrease and, therefore, the net effect on the seller's revenue of the introduction of an option is ambiguous. Finally, we examine a special case with asymmetric players who have distinct synergies. In this example, even if one player has positive synergies and the other has negative synergies, it is still possible for expected prices to decline.Received: 12 December 2000, Accepted: 1 May 2002, JEL Classification: D44Flavio Menezes acknowledges the financial support from ARC (Grant A000000055) and CNPq.

Strategic Behavior and International Benchmarking for Monopoly Price Regulation: The Case of Mexico

This paper looks into various models that address strategic behavior in the supply of gas by the Mexican monopoly Pemex. The paper has three very strong technical results. First, the netback pricing rule for the price of domestic natural gas (based on a Houston benchmark price) leads to discontinuities in Pemex’s revenue function. Second, having Pemex pay for the gas it uses and the gas it flares increases the value of the Lagrange multiplier associated with the gas processing constraint. Third, if the gas processing constraint is binding, having Pemex pay for the gas it uses and flares does not change the short run optimal solution for the optimization problem, so it will have no impact on short-run behavior. These results imply three clear policy recommendations. The first is that the arbitrage point be fixed by the amount of gas Pemex has the potential to supply in the absence of processing and gathering constraints. The second is that Pemex be charged for the gas it uses in production and the gas it flares. The third is that investment in gas processing and pipeline should be in a separate account from other Pemex investment.     

Forecasting banking crises with dynamic panel probit models

Banking crises are rare events, but when they occur, their consequences are often dramatic. The aim of this paper is to contribute to the toolkit of early warning models that is available to policy makers by exploring the dynamics and exuberances embedded in a panel dataset that covers 22 European countries over four decades (from 1970Q1 to 2012Q4). The in- and out-of-sample forecast performances of several (dynamic) probit models are evaluated, with the objective of developing common vulnerability indicators with early warning properties. The results obtained show that adding dynamic components and exuberance indicators to the models improves the performances of early warning models significantly.     

Economic valuation of habitat defragmentation: A study of the Veluwe, the Netherlands

This paper offers an economic value assessment of a nature protection programme in the Veluwe, the Netherlands. This programme involves two defragmentation scenarios: the first scenario connects the central part of the Veluwe with river forelands in a north-eastern direction (i.e. the meadows of the IJssel river), while the second scenario is focussed on defragmentation in a south-western direction (i.e. the meadows of the Rhine river). The valuation is based on a questionnaire that was administered during face-to-face interviews in the area and through the Internet. We employ a contingent valuation approach to assess the respondents' willingness to pay for the realisation of the defragmentation scenarios. It appears that the mean willingness to pay (WTP) for the two defragmentation scenarios is € 162.2 (lognormal distribution) per respondent. Because the Veluwe is considered a nature park of national importance, we performed an aggregation of individual WTP estimates over Dutch households. With the resulting aggregate estimates we can compare the total costs and benefits of the two scenarios for habitat defragmentation in the Veluwe. In addition, we test whether respondents value the two scenarios equally. We also check whether the methods of data collection (face-to-face interviews and Internet questionnaires) have distinct influences on the stated WTP responses.     

The Dynamics of International Trade Patterns

This paper introduces new dynamic measures for examining changes in international trade patterns. Using data for 20 OECD countries over the 1980–2000 period, we show that inter-industry trade changes contrary to countries’ previous specialization are frequently the dominant form of trade expansion. The econometric analysis indicates that the observed changes in trade patterns were explained by initial endowments of human-capital and industry-specific changes in labour productivity and labour costs. The results also suggest that trade liberalization induced an increase in the previous specialization of larger OECD economies in industries with increasing returns to scale. JEL no. F1, O33, O50
