Luther and the Girls: Religious Denomination and the Female Education Gap in Nineteenth‐century Prussia*

Martin Luther urged each town to have a girls' school so that girls would learn to read the Gospel, thereby evoking a surge of building girls' schools in Protestant areas. Using county‐ and town‐level data from the first Prussian census of 1816, we show that a larger share of Protestants decreased the gender gap in basic education. This result holds when using only the exogenous variation in Protestantism due to a county's or town's distance to Wittenberg, the birthplace of the Reformation. Similar results are found for the gender gap in literacy among the adult population in 1871.     

Public policies,pressure groups,and dead weight costs

This paper presents a model of competition among special interest groups for political influence. Each active group exerts pressure to affect its taxes and subsidies, where activities of different groups are related by the equality between total tax collections and total tax subsidies. The dead weight costs and benefits of taxes and subsidies play a major role in our model. An increase in the dead weight cost of taxation encourages pressure by taxpayers, while an increase in the dead weight costs of subsidies discourages pressure by recipients. Various applications of the analysis are discussed.     

Consumer profiles section: Consumer profiles for conventional bed and waterbed owners in Canada

This study examines consumer profile data on waterbed and conventional bed consumers. Five hundred conventional and waterbed consumers in Canada were randomly selected from two national lists of waterbed/mattress purchasers from 1981 to the present. A 73-item questionnaire was sent by mail to all of the selected respondents. The cover letter stated the purpose of the project; to study why people bought the bed that they are presently using. One hundred and sixty-two completed, useable questionnaires were returned, yielding a response rate of 37%. Following a series of multivariate analyses, a consumer profile for the two bed users was developed. Both groups tended to be married. The conventional bed consumers had: (a) either no children or one child at home; (b) a mean age of 44; and, (c) an average income in the $30,000-$40,000 range. Waterbed consumers had: (a) a mean age of 36, (b) one child living at home; and, (c) an average income in the $20,000-$30,000 range. On the Adorno F scale, the conventional bed user was found to be more conservative and authoritarian as compared to the waterbed user. The results did not support the notion that waterbed users are abnormally sexually-oriented or “kinky”. For both groups, the price paid for the purchased bed fell in the $600 to $650 range. Implications for retailers were discussed.     

Robust min–max portfolio strategies for rival forecast and risk scenarios

We consider an extension of the Markowitz mean–variance optimization framework to multiple return and risk scenarios. It is well known that asset return forecasts and risk estimates are inherently inaccurate. The method proposed provides a means for considering rival representations of the future. The optimal portfolio is computed, simultaneously with the worst case, to take account of all rival scenarios. This is a min-max strategy which is essentially equivalent to a robust pooling of the scenarios. Robustness is ensured by the noninferiority of min–max. For example, a basic worst-case optimal return is guaranteed in view of multiple return scenarios. If robustness happens to have too high a cost, guided by the min–max pooling, it is also possible to explore other pooling alternatives. A min–max algorithm is used to solve the problem and illustrate the robust character of min–max with return and risk scenarios. We study the properties of the min–max risk–return frontier and compare with the potentially suboptimal worst-case where the investment strategy and the worst case are computed separately.     

Selecting Agricultural Best Management Practices for Water Conservation and Quality Improvements Using Atanassov’s Intuitionistic Fuzzy Sets

Improper agricultural practices can affect ground water through leaching, surface water through runoff, algae infestations, deforestation, and air quality through burning operations and ammonia emissions. These effects may be mitigated through the institution of best management practices. The utility of best management practices (BMPs) is recognized and being actively promoted by agricultural agencies; however, identifying a set of mandatory BMPs is inappropriate given variations between climactic, demographic and geographic regions as well as differences in farming practices. In this study, a multi-criteria decision making model based on Attanassov’s Intuitionistic Fuzzy Set (A-IFS) theory is introduced and its utility to rank agricultural best management practices is illustrated using a case-study from South Texas. Implementation of the A-IFS MCDM method to the South Texas region resulted in “irrigation scheduling” being ranked as the most preferred alternative, while “brush control/management” was the least preferred. The A-IFS MCDM approach was particularly suitable for prioritizing and ranking agricultural best management practices because decision makers often tend to have both likes and dislikes with regards to specific BMPs and for a given evaluation attribute. Not only does the A-IFS MCDM method provide a single composite score to rank the BMP alternatives, but the output of the A-IFS MCDM method also includes upper and lower bounds that help identify the uncertainties in the decision making process.     

The Political Economy of Brexit: Why Making It Easier to Leave the Club Could Improve the EU

The UK exit from the EU represents a qualitative change in the nature of EU membership. On the one hand, it conveyed the lesson that for the Union to be sustainable, membership needs to entail constant caretaking as far as individual members’ contributions to the common good are concerned, with both rights and obligations. Countries with preferences that are too divergent for the Union to function properly should then not be discouraged to invoke Article 50 and to opt instead for membership in the EEA or for a free trade agreement. The Union has to deliver to be sustainable, but it cannot do so if there is a constant hold up of decisions that are in the common interest. On the other hand, with the eurozone having established itself as the de facto core of European (political) integration, the UK’s preference for a stand-alone (and incomplete) economic union became untenable, because the need to make the monetary union work calls for further integration and institution-building in the economic union sphere.
