This article contains a critical review of the literature on the economics of military affairs in Greece and Turkey as of December 1999. In particular, I review (a) arms race models; (b) models of the demand for military expenditure; (c) models measuring the economic impact of military expenditure; and (d) literature and issues related to indigenous arms production. I conclude with a number of summary lessons and observations of how future research might improve upon the existing body of work.

This work combines Convolutional Neural Networks (CNNs), clustering via Self-Organizing Maps (SOMs) and Hebbian Learning to propose the building blocks of Convolutional Self-Organizing Neural Networks (CSNNs), which learn representations in an unsupervised and Backpropagation-free manner. Our approach replaces the learning of traditional convolutional layers from CNNs with the competitive learning procedure of SOMs and simultaneously learns local masks between those layers with separate Hebbian-like learning rules to overcome the problem of disentangling factors of variation when filters are learned through clustering. We investigate the learned representation by designing two simple models with our building blocks, achieving comparable performance to many methods which use Backpropagation, while we reach comparable performance on Cifar10 and give baseline performances on Cifar100, Tiny ImageNet and a small subset of ImageNet for Backpropagationfree methods.

The bulk of this unusual paper consists of an extensive online annotated compilation of 113 non-computerized classroom-games, most of which can be played within one class period, to assist in the teaching of collegelevel basic micro and macroeconomic concepts (see http://www.aug.edu/~sbajmb or http://www.marietta.edu/~delemeeg).The paper itself consists of three major sections. The first catalogues, summarizes, and provides sample annotations of the games we collected. Section two makes a number of observations about the games. For instance, we notice an imbalance between games for microeconomics (many) and games for macroeconomics (few). We also detail which standard introductory economics topics are covered well and which are not covered well or missing altogether. For example, we observe that few games exist to present the proper economic role of government in economic affairs. The third section surveys the available literature on the costs and benefits of playing games in the classroom. In particular, our survey reveals that existing studies consider costs and benefits to students and instructors only partially, and we lay out a matrix that should help in the design of improved studies on the efficacy of gaming in the classroom.

We exploit variations in U.S. state firearms laws to study their relation to the spatial distribution of more than 2,700 federally licensed manufacturers of firearms for the civilian and law enforcement markets across the country. Accounting for a variety of economic factorssuch as cost, tax burden, and agglomeration effectswe find that states with relatively permissive, enduser friendly laws host more firearms manufacturing establishments than do states with relatively restrictive, end-user unfriendly laws. This supply side-oriented paper complements a literature that predominantly attends to the market's demand side. It thus opens up a new avenue to study the U.S. civilian firearms market.
