On the complete instability of empirically implemented dynamic Leontief models

On theoretical grounds, real world implementations of forward-looking dynamic Leontief systems were expected to be stable. Empirical work, however, showed the opposite to be true: all investigated systems proved to be unstable. In fact, an extreme form of instability ('complete instability') appeared to be the rule. In contrast to this, backward-looking models and dynamic inverse versions appeared to be exceptionally stable. For this stability-instability switch a number of arguments have been put forward, none of which was convincing. Dual (in)stability theorems only seemed to complicate matters even more. In this paper we offer an explanation. We show that in the balanced growth case--under certain conditions--the spectrum of eigenvalues of matrix D equivalent to (I - A)-1B, where A stands for the matrix of intermediate input coefficients and B for the capital matrix, will closely approximate the spectrum of a positive matrix of rank one. From this property the observed instability properties are easily derived. We argue that the employed approximations are not unrealistic in view of the data available up to now

One Rule of Law Project in Post-Soviet Russia

One Rule of Law Project in Post-Soviet Russia is published as Chapter 9 of the book At Home Abroad: Friendship First - A Look at Rule of Law Projects and Other International Insights, (ed. Joseph Nadeau, New York: Austin Macauley Publishers LLC, 2019). This book provides personal insights into an international cooperative effort to promote the rule of law in emerging democracies around the world. Professor Scherr\u27s chapter examines the cultural context within a study of the rule-of-law project that was conducted between 1999 and 2004 in Vologda, Russia

A survey of environmental problems in Eastern Europe

This paper deals with the increasing interaction of economic and environmental issues in Eastern Europe. The paper starts with a discussion of environmental problems in these formerly centrally planned economies. The grave environmental problems these countries face are surveyed and an explanation is provided in terms of the nature of the communist system. While a solution must be sought in an international cooperation context, involving the developed West European countries, many emerging international cooperation schemes inspired by environmental economic theory are no longer effective in the light of the disastrous loss of competitiveness of East European industries. New initiatives on the part of West European countries seem to be called for

Brief for Professor Albert E. Scherr as Amicus Curiae in Support of Petitioner

INTRODUCTION AND SUMMARY OF ARGUMENT Professor Scherr agrees with petitioner that review is warranted because the Maryland Court of Appeals decision is erroneous. The Fourth Amendment does not sanction police harvesting of DNA without probable cause and a warrant and without the subject’s knowledge or consent, to be used however the authorities deem appropriate and without restriction. The Maryland Court of Appeals’ decision is contrary to the Supreme Court’s jurisprudence as articulated in the Riley v. California – Maryland v. King – United States v. Jones trilogy. This case fits squarely in the center of the triangle formed by that trilogy. The petition should be accepted to remedy this conflict at the intersection of this Court’s jurisprudence on the newest forensic technology and the Fourth Amendment. Professor Scherr also agrees with the petitioner that this Court should accept this petition to resolve a conflict between a Federal Court of Appeals and a state court of appeals. In United States v. Davis, 690 F.3d 226 (4th Cir. 2012), the Fourth Circuit found that the police implicated the suspect’s Fourth Amendment privacy interest when it sought to obtain a DNA profile from his blood found on clothing it held legally. In this case the Maryland Court of Appeals found the opposite. As surreptitious harvesting cases continue to enter the criminal justice system, it is an opportune time for this Court to resolve this conflict and offer guidance to state and federal courts

The Norman Site: Descriptions

The Norman site (34WG2) lay on a terrace on the west side of the Neosho (Grand) River in Wagoner County, Oklahoma. Throughout much of its course within Oklahoma, this river flows along the western boundary of the Ozark Uplift. East of the river, the limestones, shales, and sandstones deposited during the Upper Mississippian and Pennsylvanian geological periods form the Boston Mountains and the Springfield Plateau. Several of these formations contain knappable cherts, often of good quality. West of the river, the Mississippian and Pennsylvanian deposits thin and dip under the surface to form the Prairie Plains Province, characterized by low, east-facing escarpments. Sandstone and shale bedrocks underlie the Prairie-Plains Province. The streams flowing eastward across these are muddy and sluggish

A Formal, Resource Consumption-Preserving Translation of Actors to Haskell

We present a formal translation of an actor-based language with cooperative scheduling to the functional language Haskell. The translation is proven correct with respect to a formal semantics of the source language and a high-level operational semantics of the target, i.e. a subset of Haskell. The main correctness theorem is expressed in terms of a simulation relation between the operational semantics of actor programs and their translation. This allows us to then prove that the resource consumption is preserved over this translation, as we establish an equivalence of the cost of the original and Haskell-translated execution traces.Comment: Pre-proceedings paper presented at the 26th International Symposium on Logic-Based Program Synthesis and Transformation (LOPSTR 2016), Edinburgh, Scotland UK, 6-8 September 2016 (arXiv:1608.02534
