Third-party threat and the dimensionality of major-party roll call voting

This paper assesses the influence of the electoral threat of third parties on major-party roll call voting in the US House. Although low-dimensionality of voting is a feature of strong two-party politics, which describes the contemporary era, there is significant variation across members. I hypothesize that major-party incumbents in districts under a high threat from third-party House candidates cast votes that do not fit neatly onto the dominant ideological dimension. This hypothesis is driven by (1) third party interests in orthogonal issues, and (2) incumbents accounting for those interests when casting votes in order to minimize the impact of third parties. An empirical test using data from the 105th to 109th Congresses provides evidence of this effect.     

Explaining variation in the competitiveness of U.S. Senate elections, 1922–2004

We develop and test predictions about the factors determining the competitiveness of elections to the U.S. Senate. To do so, we deliberately abstract away from candidate-specific conditions that have often been used to study political competitiveness in order to focus on basic structural features of the electoral landscape. In our framework, party-specific constraints on the ideological positioning of local candidates, linked to the national party organization and its contributors, interact with the heterogeneity of state electorates to determine the number of highly competitive Senate contests. Three hypotheses emerge from this model: (1) the greater the diversity of a party’s national legislative delegation, the more highly competitive Senate elections we will observe; (2) states in which the ideological heterogeneity of the electorate is relatively high will exhibit a greater number of highly competitive elections; and (3) highly competitive Senate contests will be more common in states with closed primaries than in states with open primaries. We provide strong evidence in support of the first two hypotheses and some evidence in support of the third.     

Do Voters Respond to Party Manifestos or to a Wider Information Environment? An Analysis of Mass‐Elite Linkages on European Integration

Recent studies analyze how citizens update their perceptions of parties’ left‐right positions in response to new political information. We extend this research to consider the issue of European integration, and we report theoretical and empirical analyses that citizens do not update their perceptions of parties’ positions in response to election manifestos, but that citizens’ perceptions of parties’ positions do track political experts’ perceptions of these positions, and, moreover, that it is party supporters who disproportionately perceive their preferred party's policy shifts. Given that experts plausibly consider a wide range of information, these findings imply that citizens weigh the wider informational environment when assessing parties’ positions. We also present evidence that citizens’ perceptions of party position shifts matter, in that they drive partisan sorting in the mass public.     

Think globally,buy locally: International agreements and government procurement

Do international treaties constrain national governments? The answer appears to be “yes” when it comes to the use of traditional barriers to trade, such as tariffs. Yet, while many governments have cut tariffs to comply with international agreements, they have often raised non-tariff barriers in their place. One increasingly prominent non-tariff barrier is discrimination in public procurement. Governments frequently discriminate against foreign suppliers in favor of domestic ones when buying goods and services. In an attempt to reduce procurement discrimination, international organizations, such as the World Trade Organization, have devoted ever more attention to members’ procurement practices. Additionally, a growing number of preferential trade agreements seek to regulate public procurement. It remains unclear, however, whether international rules are effective in changing governments’ purchasing behavior. Using original data, we find that neither multilateral nor preferential procurement agreements substantially reduce governments’ propensity to “buy national.” These results illustrate the difficulty of regulating non-transparent policy areas via international treaties.     

China’s direct investment in the European Union: a new regulatory challenge?

While China is fast becoming an important outward direct investor, its companies are showing an increasing interest to locate in Europe and the European Union (EU). It has been suggested that this can partly be explained by the more lenient attitude of the European countries compared to the US, where some acquisitions were abandoned when they ran into political opposition based on security concerns. Yet, also in Europe, the media follow rather closely each new Chinese entry, and certain politicians have started to criticise the take-over of technology-oriented companies, especially by Chinese state-owned firms. Against the background of a very open foreign direct investment (FDI) policy as measured by OECD FDI Restrictiveness Index for the EU and the individual countries, an overview is given of the pre- and post-establishment obstacles to direct foreign investment. Also, the EU policy measures that directly or indirectly deal with incoming direct investment are discussed. Within the context of the EU competition policy and the merger regulation, the EU Commission has cleared five cases of take-over by Chinese state-owned enterprises. Although the Lisbon Treaty authorises the EU Commission to take charge of investment policy as part of the EU commercial policy, it will take time to realise this. If the announced negotiations about an investment treaty between China and the EU could work out the necessary balance, it would be an important step in achieving more reciprocity between their respective investment regimes.     

Using Spatial,Temporal and Evidence‐status Data to Improve Ballistic Imaging Performance

Firearms identification imaging systems help solve crimes by comparing newly acquired images of cartridge casings or bullets to a database of images obtained from past crime scenes. We formulate an optimization problem that bases its matching decisions not only on the similarity between pairs of images, but also on the time and spatial location of each new acquisition and each database entry. The objective is to maximize the detection probability subject to a constraint on the false positive rate. We use data on all cartridge casings matches detected in Israel during 2006–2008 to estimate most of the model parameters. We estimate matching accuracy from two different studies and predict that the optimal use of extraneous information would increase the detection probability from 0.931 to 0.987 and from 0.707 to 0.844, respectively. These improvements are achieved by favoring pairs of images that are closer together in space and time.     

Acute Aortic Dissection Diagnosed after Embalming: Macroscopic and Microscopic Findings

A 58‐year‐old man died suddenly in Madagascar and poisoning was suspected. The body was embalmed after death and the general state of preservation was good. We found a major aortic dissection with a large false lumen from the aortic root to the common iliac arteries and a hemopericardium with formalinized blood clot. The intimal tear was on the ascending aorta, and an intramural hemorrhage was noted at the right coronary artery, attesting to a retrograde dissection. Microscopic studies confirmed aortic dissection with extensive intramural hemorrhage and also confirmed the retrograde dissection to the right coronary artery with a reduction of 90% of the true lumen. Classically, aortic dissection occurs in individuals with hypertension and individuals with genetic disorders of collagen formation. The diagnosis is often first established at the postmortem examination. Aortic dissection is therefore dealt with largely in necropsy studies. The usual cause of death is rupture into the pericardial sac. One case of bloodless dissection has been reported but the sudden death was explained by acute myocardial ischemia secondary to dissection of the left coronary artery. In our case, we found major hemopericardium and also intramural hemorrhage at the right coronary artery. We were able to make the diagnosis of aortic dissection and exclude the suspicion of homicide 15 days after death and after embalming.
