Valuing Options in Water Markets: A Laboratory Investigation
Risk and reliability dominate water supply discussions in the arid western United States in light of increasing demand and finite, weather-dependant supply. Thus water agencies increasingly turn to contractual mechanisms such as dry-year options to manage supply risk in advance of need. Although a few water agencies across the West have implemented dry-year options, sufficient data for conventional econometric analysis do not yet exist. We thus utilize experimental economics to analyze the effect of annual dry-year options on water markets. We consider how market structure (competitive versus monopsony power) and option contract availability affect water price and allocation within a market and find that realized gains from trade are on average higher when options can be traded, by 46% in competitive markets and by 63% in dominant buyer markets. Important for the political feasibility of such markets, we also find that gains from trade, once an options market is available, are much more evenly distributed between the single buyer and the many sellers in the case of monopsony.Resource /Energy Economics and Policy, D23, L22, Q25,
Valuing Options in California Water Markets: A Laboratory Investigation
Risk and reliability dominate water supply discussions in the arid western United States. In the past, water managers built additional storage to mitigate supply risk. The optimal, least expensive storage sites have now been taken, and there are strong, environmental objections to new facilities. Reliability of existing supplies is further diminished due to concerns about endangered species and global climate change. Thus water agencies increasingly turn to contractual mechanisms such as dry-year options to manage supply risk in advance of need. However, although a few water agencies across the West have implemented dry-year options, sufficient data for conventional econometric analysis do not yet exist. We thus utilize experimental economics to analyze the effect of annual dry-year options on water markets. How do market structure (competitive versus market power) and option contract availability affect water price and allocation within a market? Experiment participants trade stochastic realizations of water in a non-uniform double auction parameterized to resemble the California water market. We find that realized gains from trade are on average higher when options can be traded, by 11% in competitive markets and by 21% in dominant buyer markets. Findings in this analysis may assist policymakers in preparing for the next multi-year drought in California.Resource /Energy Economics and Policy,

Flesh of the Same Flesh: A Study of Voters for the Alternative for Germany (AfD) in the 2017 Federal Election
Using the 2017 post-election German Longitudinal Election Study (GLES), this article examines the voters for the Alternative for Germany (AfD) in the 2017 German federal election. We show that AfD voters in 2017 were truly ‘flesh of the same flesh’ of the mainstream German political parties, with the AfD drawing its voters from across the political party spectrum as well as from previous non-voters in 2013. In contrast to previous scholarship, we find that in most respects AfD voters in 2017 did not differ demographically from voters for all other parties, be that in terms of gender, education, employment status, and union membership. Furthermore, we find that AfD voters were not driven by anxiety about their own economic situation: they are no ‘losers of globalisation.’ Instead, AfD voters in 2017 were driven solely by two factors: their attitudes towards immigrants/refugees and anti-establishment sentiment/satisfaction with democracy in Germany.</p
Pulling up the Drawbridge: Anti-Immigrant Attitudes and Support for the Alternative for Germany (AfD) Among Russian-Germans
The most recent scholarship on the Alternative for Germany (AfD) indicates that citizens primarily cast a vote for the party based on anti-immigrant or xenophobic attitudes. Nevertheless, prominent figures from the AfD suggest that many Germany citizens with immigrant backgrounds vote for it - an argument that has been picked up by the media. In this article, we investigate the most likely potential constituency of immigrants that might support the AfD: ethnic German migrants from the former Soviet Union, so-called Russian-Germans. Using the 2017 Immigrant German Election Study (imges), we find that these ethnic German migrants from the former Soviet Union indeed voted for the AfD in relatively large numbers when compared to the overall population. Furthermore, when predicting vote choice, we find that the main predictor of voting for the AfD among Russian-Germans is not political ideology but rather a simple hostility towards new refugees. Crucially, migrants with a Soviet background are more likely to vote for the AfD if they hold the position that there should be no economic or political refugees allowed into the country.</p
Rhapsody in Beige: The Impact of SPD Candidate Evaluations on Vote Choice in the 2009, 2013, and 2017 Federal Elections
Previous research has shown that in addition to party identification chancellor candidate evaluations play an important role in determining vote choice in German federal elections. In this article, we evaluate the impact that such evaluations had on vote choice in 2009, 2013, and 2017 using the German Longitudinal Election Study. In contrast to a popular narrative that Chancellor Merkel was less of a factor in 2017 than she had been in the two previous elections where the Union parties ran especially personalised campaigns around Merkel, we find that the Kanzlerbonus (incumbency benefit) and Merkel’s attractiveness to voters was strong in all three elections, especially among non-party identifiers. More importantly, we find that increasingly the Social Democrats had chancellor candidates unattractive to voters and perceived as bland across all of these elections, and demonstrate that this was a factor which significantly weakened their vote. Thus we conclude that beyond the structural weaknesses of the Social Democrats over the last three election cycles the lack of appeal of the party’s chancellor candidates has played a significant role in the SPD’s lack of electoral success.</p
The Alternative for Germany (AfD) as Populist Issue Entrepreneur: Explaining the Party and its Voters in the 2021 German Federal Election
This article analyses the vote for the Alternative for Germany (AfD) in the 2021 German Federal Election. Using the German Longitudinal Election Study (GLES), we confirm some findings from previous studies, above all that attitudinal variables - including anti-immigrant ideology - are much stronger predictors of the AfD vote than socio-demographic variables. Moreover, we uncover three new findings in relation to vote choice for the AfD. First, anti-EU attitudes had a positive, statistically significant impact on AfD vote choice in 2021. Second, negative attitudes towards political elites increased the probability of voting for the AfD. Third, and perhaps most important, dissatisfaction with the government’s handling of the COVID-19 pandemic was positively related to voting for the AfD. Given these results, we argue here that the AfD has become something of a populist 'issue entrepreneur' which, while exploiting existing niches in the electoral marketplace (the EU and migration), is finding new issues to tap and exploit

Robust model-based analysis of single-particle tracking experiments with Spot-On.
Single-particle tracking (SPT) has become an important method to bridge biochemistry and cell biology since it allows direct observation of protein binding and diffusion dynamics in live cells. However, accurately inferring information from SPT studies is challenging due to biases in both data analysis and experimental design. To address analysis bias, we introduce 'Spot-On', an intuitive web-interface. Spot-On implements a kinetic modeling framework that accounts for known biases, including molecules moving out-of-focus, and robustly infers diffusion constants and subpopulations from pooled single-molecule trajectories. To minimize inherent experimental biases, we implement and validate stroboscopic photo-activation SPT (spaSPT), which minimizes motion-blur bias and tracking errors. We validate Spot-On using experimentally realistic simulations and show that Spot-On outperforms other methods. We then apply Spot-On to spaSPT data from live mammalian cells spanning a wide range of nuclear dynamics and demonstrate that Spot-On consistently and robustly infers subpopulation fractions and diffusion constants
