description: With backwards orbit integration we estimate birth locations of young stellar associations and moving groups identified in the solar neighborhood that are younger than 70 Myr. The birth locations of most of these stellar associations are at smaller galactocentric radius than the Sun, implying that their stars moved radially outwards after birth. Exceptions to this rule include are the Argus and Octans associations which formed outside the Sun's Galactocentric radius. Variations in birth heights of the stellar associations suggest that they were born in a corrugated disk of molecular clouds, similar to that inferred from the current filamentary molecular cloud distribution and dust extinction maps. Multiple spiral arm features with different but near corotation pattern speeds and at different heights could account for the stellar association birth sites. We find that the young stellar associations are located in between peaks in the UV stellar velocity distribution for stars in the solar neighborhood. This would be expected if they were born in a spiral arm which perturbs stellar orbits that cross it. In contrast, stellar associations seem to be located near peaks in the vertical phase space distribution, suggesting that the gas in which stellar associations are born moves vertically together with the low velocity dispersion disk stars.

description: EPA recently published, for comment, a proposed set of modifications for the regulation of confined animal feeding operations (CAFOs). These proposed regulations require considerably tighter controls over discharges of animal waste. Compliance will require substantial investments by those operations that had not previously been subject to regulation because they did not meet the minimum size requirements. This review of the proposed EPA CAFO regulations results from a request of the House Committee on Agriculture to FAPRI (MO) and AFPC (TX). While designed to evaluate the procedures utilized by EPA in its economic impact statement, it also discusses alternatives for improvements in the analytical impact statement approach in order that the statement may be made economically valid. To that end, this review critiques the basic economic analysis of livestock operations as performed by EPA.

description: This paper empirically evaluates the economic performance of U.S. state governors who came to the position from a business background (CEO governors), focusing on the growth rate of real personal income per capita, unemployment rate, and income inequality. Methodologically, we apply a matching method to account for the endogeneity of political selection. Using entropy balancing, we identify credible counterfactuals for CEO governors, that is, governors without a business background who took office under similar economic and fiscal situations. We find, first, that businesspeople tend to take office in times of economic and fiscal strain. Second, the tenures of CEO governors are associated with a 0.6 percentage points higher annual income growth rate and a 0.6 percentage points lower unemployment rate than are the tenures of non-CEO governors. Also, state-level income inequality decreases when CEO governors hold office, indicating that low-income households benefit from the economic upswing. Third, the positive effect of having a CEO governor increases with time in office. Fourth, Republican CEO governors perform slightly better than their Democratic colleagues.

description: We use observations from the APOGEE survey to explore the relationship between stellar parameters and multiplicity. We combine high-resolution repeat spectroscopy for 41,363 dwarf and subgiant stars with abundance measurements from the APOGEE pipeline and distances and stellar parameters derived using \textit{Gaia} DR2 parallaxes from \cite{Sanders2018} to identify and characterise stellar multiples with periods below 30 years, corresponding to \drvm$\gtrsim$ 3 \kms, where \drvm\ is the maximum APOGEE-detected shift in the radial velocities. Chemical composition is responsible for most of the variation in the close binary fraction in our sample, with stellar parameters like mass and age playing a secondary role. In addition to the previously identified strong anti-correlation between the close binary fraction and \feh\, we find that high abundances of $α$ elements also suppress multiplicity at most values of \feh\ sampled by APOGEE. The anti-correlation between $α$ abundances and multiplicity is substantially steeper than that observed for Fe, suggesting C, O, and Si in the form of dust and ices dominate the opacity of primordial protostellar disks and their propensity for fragmentation via gravitational stability. Near \feh{} = 0 dex, the bias-corrected close binary fraction ($a<10$ au) decreases from $\approx$ 100 per cent at \alh{} = $-$0.2 dex to $\approx$ 15 per cent near \alh{} = 0.08 dex, with a suggestive turn-up to $\approx$20 per cent near \alh{} = 0.2. We conclude that the relationship between stellar multiplicity and chemical composition for sun-like dwarf stars in the field of the Milky Way is complex, and that this complexity should be accounted for in future studies of interacting binaries.

description: This thesis develops a novel constitutive model for unsaturated compacted soils, incorporating the traditional compaction curves. Dubbed as generalised MPK model, it couples hydraulic and mechanical behaviour incorporating environmental stabilisation concepts and strain accumulation upon wet-dry cycles. The model was validated by reproducing a range of phenomenological observations for isotropic and triaxial stress states both qualitatively and quantitatively.

description: With rapid income growth, dairy production and consumption in China have increased significantly. This emergence of the dairy sector will provide opportunities for farmers to participate in a high-value, potentially more lucrative enterprise. The overall goal of this paper is to analyze the major determinants of farmers’ participation in dairy production. Our main question is whether or not the pace of the emergence of the dairy processing industry has affected the ability of farmers to participate in dairy production and whether or not it has limited the expansion of their herd size. Based on household, village and processor surveys conducted in the Greater Beijing region, our analysis shows that the location of dairy processing firms is one of the key factors that determines the participation of farmers in dairy production. Although other factors affect participation and herd size—for example, access to roads and the ability to get a job off the farm (which affects the opportunity cost of household members)—access to dairy processors is shown to be the major factor that has encouraged the growth of dairy production over the past decade. The results also show that poor, less educated farmers with relatively less access to land are not excluded from the rapid expansion of the Greater Beijing dairy market.

description: We generalize the predictions for the CMB anisotropy patterns arising in Bianchi type VIIh universes to include a dark energy component. We consider these models in light of the result of Jaffe et al. (2005a,b) in which a correlation was found on large angular scales between the WMAP data and the anisotropy structure in a low density Bianchi universe. We find that by including a term Omega_L > 0, the same best-fit anisotropy pattern is reproduced by several combinations of cosmological parameters. This sub-set of models can then be further constrained by current observations that limit the values of various cosmological parameters. In particular, we consider the so-called geometric degeneracy in these parameters imposed by the peak structure of the WMAP data itself. Apparently, despite the additional freedom allowed by the dark energy component, the modified Bianchi models are ruled out at high significance.

description: Of the many issues associated with modifying the 1996 FAIR Act, equitability of government support across program commodities ranks high on the list of priorities. This concern is associated with both a limited amount of government support and the method that can be used to derive or ascertain some measure of equitability. Likewise, government support that is out of balance across commodities can likely become the supply inducing expected revenue -- which tends to erode market signals. This may be particularly true in times of very low (below loan rate) prices. A reference point commonly used to focus this debate is the variable cost of production per unit of commodity produced. The reason for selecting this measure is that it only reflects costs associated with planting to harvest of the crop. Other costs are deliberately excluded such that comparisons can more easily be made across commodities and regions. Obviously, other costs such as land are important and are included in the total cost of production. However, a logical first step in an economic evaluation of equitability for government support across commodities is the expected unit of return relative to the variable cost of production. After making this derivation, it is relatively easy to calculate whether the margin generated will support other costs including -- land, taxes, a return to management, etc.

description: Despite negative experiences with auctioning off subsidies for renewable energy in some countries, tenders are increasingly used today. We develop a reverse auction which accounts for particularities of intermittent renewable energy sources. Determining the quantity, demanded by the regulator, is internalized and directly linked to his two main objectives. On the one hand, the regulator seeks for a high share of renewable energy. On the other hand, he wants to enhance burden sharing between electricity consumers and renewable electricity producers. We further account for asymmetric information in reverse auctions. We analyze incentives for bidders to manipulate the auction outcome and adapt the design to prevent this behavior. Regional features as grid and generating capacity can be considered to optimize the deployment of renewable energy. We thereby introduce a link to fossil capacity auctions.

description: Anti-eavesdropping channel estimation (ANECE) is a method that uses specially designed pilot signals to allow two or more full-duplex radio devices each with one or more antennas to estimate their channel state information (CSI) consistently and at the same time prevent eavesdropper (Eve) with any number of antennas from obtaining its CSI consistently. This paper presents optimal designs of the pilots for ANECE based on two criteria. The first is the mean squared error (MSE) of channel estimation for the users, and the second is the mutual information (MI) between the pilot-driven signals observed by the users. Closed-form optimal pilots are shown under the sum-MSE and sum-MI criteria subject to a symmetric and isotropic condition. Algorithms for computing the optimal pilots are shown for general cases. Fairness issues for three or more users are discussed. The performances of different designs are compared.

description: Adiabatic time-dependent density functional theory fails for excitations of a heteroatomic molecule composed of two open-shell fragments at large separation. Strong frequency-dependence of the exchange-correlation kernel is necessary for both local and charge-transfer excitations. The root of this is static correlation created by the step in the exact Kohn-Sham ground-state potential between the two fragments. An approximate non-empirical kernel is derived for excited molecular dissociation curves at large separation. Our result is also relevant for the usual local and semi-local approximations for the ground-state potential, as static correlation there arises from the coalescence of the highest occupied and lowest unoccupied orbital energies as the molecule dissociates.

description: This paper investigates empirically whether prostitution reduces sex crimes.
Theoretical predictions suggest two contradicting effects: substituting or complementing. By using survey data of sex offenders in Korea, I find that prostitution increases the probability of committing sex crimes. Also, the experience of buying sex with a minor exacerbates the severity of sex crimes. These results indicate that prostitution intensifies one’s propensities for more violent sexual behaviors, suggesting a complementary relationship between prostitution and sex crimes. The main findings do not alter after accounting for the endogeneity of the model by applying an exogenous instrument – the location of red-light districts.

description: Gradient-domain machine learning (GDML) is an accurate and efficient approach to learn a molecular potential and associated force field based on the kernel ridge regression algorithm. Here, we demonstrate its application to learn an effective coarse-grained (CG) model from all-atom simulation data in a sample efficient manner. The coarse-grained force field is learned by following the thermodynamic consistency principle, here by minimizing the error between the predicted coarse-grained force and the all-atom mean force in the coarse-grained coordinates. Solving this problem by GDML directly is impossible because coarse-graining requires averaging over many training data points, resulting in impractical memory requirements for storing the kernel matrices. In this work, we propose a data-efficient and memory-saving alternative. Using ensemble learning and stratified sampling, we propose a 2-layer training scheme that enables GDML to learn an effective coarse-grained model. We illustrate our method on a simple biomolecular system, alanine dipeptide, by reconstructing the free energy landscape of a coarse-grained variant of this molecule. Our novel GDML training scheme yields a smaller free energy error than neural networks when the training set is small, and a comparably high accuracy when the training set is sufficiently large.

description: This article introduces discourse analysis as a theoretical concept and an empirical methodology that may enable the endogenization of path creation and path breaking changes in conventional models of political path dependencies. Economic criteria such as rents created by a policy do not always provide a comprehensive explanation for path dependent political decisions. Discourse theory implies that specific interpretative schemata and narratives, such as story lines in the mass media, heavily influence the political discourse. Discourses themselves exercise a constitutive power that constrains decision-making processes and, thus, influence the ensuing policy creation path. Hence, discourses must be taken into account when political path creation is analysed. In this paper we trace over time individual story lines that represent important elements of the discourse underlying the restriction of seasonal farm workers from central and eastern European countries in Germany. We illustrate how dominant speakers and their story lines have been and currently are interacting to shape this policy.

description: This paper analyzes the impact of guaranteed minimum price contracts between sub-groups of farmers and a fair trade manufacturer on the spot market price. We focus on the fair trade concept in the coffee supply chain as an example. We analyze a three level vertical chain gathering perfectly competitive farmers upstream who offer their raw product to manufacturers who then sell finished products to a downstream retailer. Without fair trade, all the raw product is sold on the spot market. When a sub-group of farmers benefit from a guaranteed minimum price contract offered by a fair trade certifier, we show that farmers outside of this fair trade agreement may also benefit from a higher spot market price in cases of a limited overproduction.

macroprudential policy

description: The financial crisis proved strikingly that stabilizing the price level is a neces-
sary but not a sufficient condition to ensure macroeconomic stability. The obvious candidate for addressing systemic risk is macroprudential policy. In this paper we study the optimal monetary and macroprudential policy mix in a currency union in the case of different kinds of aggregate and idiosyncratic shocks. The monetary and macroprudential instruments are modelled as independent tools. With a union-wide macroprudential tool, full absorption on the aggregate level is possible, but welfare losses due to fluctuations in relative variables prevail. With country-specific macroprudential tools, full absorption of shocks is always possible. But it is only optimal as long as there is no ine¢ cient labor allocation. Comparing di¤erent policy regimes, we get the following ranking in terms of welfare: discretion outperforms strict inflation targeting which outperforms a (euro-area based) Taylor Rule.

description: The present study examines factor content in the CEE transition country agricultural trade. However, deviating from the traditional approach, we do not test the HOV prediction. Instead, we examine the theoretical predictions that relate the factor content of international trade to cross-country differences in technology and endowments. Our empirical findings suggest that factor content between agricultural exports and imports is rather similar in CEE. In order to explain the general lack of the CEE agricultural specialisation and the observed paradox, we attempt to identify the role of transaction costs and market imperfections in determining factor content in agricultural production and trade. We find that technological differences and factor endowment are only weak determinants of country specialisation. Transaction costs and market imperfections distort farm specialisation and organisation in CEE, and hence factor content in traded agricultural goods.

description: This paper identifies and assesses the efficiency of major modes for risk governance in Bulgarian dairy farming. Firstly, New Institutional Economics is incorporated and framework for analyzing governance of natural, market, private, and social (institutional) risks presented. Next, major types of risks faced by the dairy farms are specified and dominant market, private, public and hybrid modes of risk governance assessed. Finally, principal forms of risks caused by the dairy farms are identified, and efficiency of governing structure assessed. The development of Bulgarian dairy farming has been associated with quite specific risk structures facing by and causing from this sector. The huge market and institutional instability and uncertainty, and the high transaction costs, blocked evolution of effective market and collective modes for risk protection. A variety of private modes (internal organization, vertical integration, interlinking) emerged to deal with the significant natural, market, private, and social risks faced by the dairy farms and the other affected agents. Nevertheless, diverse risks associated with the dairy farming have not been effectively governed and persist during transition now. That is a consequence of ineffective public (Government, international assistance) intervention to correct market and private sector failures in the risk governance. The later have had considerable negative impacts on the evolution of farms, development of markets, structure of production and consumption, state of environment etc. Certain risks related to the dairy sector “disappeared” due to the lack of effective risk governance and the declining dairy farming. That would lead to further deformation in development of the dairy and related sectors unless effective public measures are taken to mitigate existing problems and risks.

description: In rural areas, small and medium-sized municipalities are challenged by demographic change and intensified competition for capital and high-skilled labor. Inter-municipal cooperation (IMC) is often regarded as a significant element of a strategy to meet these challenges. Based on a survey in three rural counties in the German state of Hesse, we present first evidence on citizens’ policy preferences regarding IMC. Policy preferences are found to be driven primarily by individual characteristics. The strongest factor reducing citizens’ support is the belief that IMC reduces citizens’ influence and control. Support is higher among citizens who assess the current service quality as low and/or assess the future perspective of their home municipality as negative. Trust in local politicians and a high degree of emotional attachment to the home municipality have a negative impact on subjects’ support for IMC. None of the municipal characteristics like municipal size or fiscal stress, nor the availability of suitable partner municipalities are found to drive citizens’ preferences.

description: We have discovered several severe errors in the recent paper M. Hu, K. Guo, Q. Yu, Z. Zhang [Superlattices and Microstructures, 122 (2018) 538-547]. Specifically, we demonstrate that both the solution of the Schrödinger equation and the bound-state wave functions used in the paper are incorrect.

description: We study the effects of preselection on an expert’s incentive to give truthful advice in a decision environment in which certain decisions yield more precise estimates about the expert’s expertise. The introduction of a preselection stage, in which the decision maker can study the case before asking for advice, alters the expert’s perception of the problem. We identify conditions under which preselection occurs in equilibrium. We show that if the expert adjusts his behavior, the option to preselect may reduce the expected utility of the decision maker.

description: In 1973, British Columbia created the Agricultural Land Reserve (ALR) to protect farmland from development. This study investigates whether the ALR has been effective near the city of Victoria. Therefore, we employ a GIS-based hedonic pricing model and quantify ALR specific measures. Bayesian Model Averaging in combination with Markov Chain Monte Carlo Model Composition are used to address specification uncertainty. Results show that zoning schemes are partly credible. Zoned farmland sells for lower prices than other farmland. However, farmland located closer to the city of Victoria is priced higher and hobby farmers pay higher prices than conventional farmers.

description: Anomalous triangle graphs for the divergence of the axial-vector current are studied using the dispersive approach generalized for the case of higher orders of perturbation theory. The validity of this procedure is proved up to two-loop level. By direct calculation in the framework of dispersive approach we have obtained that the two-loop AVV amplitude is equal to zero. According to the Vainshtein's theorem the transversal part of the anomalous triangle is not renormalized in the chiral limit. We generalize this theorem for tha case of finite fermion mass in the triangle loop.

description: We present a quantum optics approach for describing stimulated parametric down conversion in the two type-I crystal "sandwich" configuration, which allows for parametric interaction of vector vortex beams. We analyze the conditions for which phase conjugation of the seed vector beam occurs. We then use two strategies for defining generalized Stokes parameters to describe phase conjugation of vector vortex beams. These allow for geometrical representations, such as higher-order Poincaré spheres. Our results are useful for description and design of stimulated and spontaneous parametric down conversion experiments with vector vortex beams.

description: This paper covers those parts of elementary logic that are needed in
an introductory course on philosophy of science and the methodology
of economics. With this aim in mind, much of the technical material
from standard logic courses can be dropped. Specifically, the exposition
emphasizes the semantic side, with only a few remarks on syntacti-
cal aspects. On the other hand, some philosophical and methodological
remarks are in order to prepare the ground for methodological discus-
sions. Where appropriate, exercises (including review questions and
discussion questions) are provided. Solutions to selected exercises are
given at the end of the paper.

description: The improvement of the sustainable performance of the agricultural sector is a priority of the Swiss agricultural policy. The sustainability of Swiss dairy farms located in the mountainous area might be critical as many of them show a weak performance in the use of their economic and/or social resources, and sometimes also of their environmental resources. An improvement of the sustainability of these farms prerequisites to better know on a large scale their sustainable performance and its determinants. For a representative sample of 480 dairy farms, we perform an assessment of their sustainable efficiency with the “sustainable value”, an approach to assess corporate sustainability based on the capital and opportunity cost theories. Using a linear regression, we analyze the determinants of the sustainable efficiency. The results show a tight positive relationship between sustainable performance and pure economic performance. The intensity of the use of intermediate consumptions is found to be the most important determinant of the sustainable efficiency. Farms with a high sustainable efficiency are those that use their intermediate consumptions in the most efficient way. The part of direct payments in the gross profit is shown to negatively affect the sustainable efficiency. The structural characteristics of the farms and the sociologic characteristics of the farmer managers are shown to hardly influence the sustainable efficiency.

description: Dark photons (DPs) produced in the early Universe are well-motivated dark matter (DM) candidates. We show that the recently proposed tunable plasma haloscopes are particularly advantageous for DP searches. While in-medium effects suppress the DP signal in conventional searches, plasma haloscopes make use of metamaterials that enable resonant absorption of the DP by matching its mass to a tunable plasma frequency and thus enable efficient plasmon production. Using thermal field theory, we confirm the in-medium DP absorption rate within the detector. This scheme allows to competitively explore a significant part of the DP DM parameter space in the DP mass range of $6-400$ $μ$eV. If a signal is observed, the observation of a daily or annual modulation of the signal would be crucial to clearly identify the signal as due to DP DM and could shed light on the production mechanism.

description: It has long been argued that geographic co-location supports knowledge spillovers. More recently, this argument has been challenged by showing that knowledge spillovers mainly flow through social networks, which may or may not be localized at various geographic scales. We further scrutinize the conjecture of geographically bounded knowledge spillovers by focusing on knowledge flows between academia and industry. Looking into citations to non-patent literature (NPL) in 2,385 Dutch polymer patents, we find that citation lags are shorter on average if Dutch rather than foreign NPLs are cited. However, when excluding individual and organizational self-citations, geographically proximate NPLs no longer diffuse faster than foreign NPLs. This suggests that knowledge is not “in the air” but transferred by mobile individuals and/or direct university-industry collaboration. Our findings moreover suggest an important role of international conferences in the diffusion of recent scientific knowledge.
