Super-simple designs are useful in constructing codes and designs such as superimposed codes and perfect hash families. Recently, Gronau et al determined the existence of super-simple (v, 5, 2)-BIBDs with possible exceptions of v ∈ {75, 95, 115, 135, 195, 215, 231, 285, 365, 385, 515}. In this article, we investigate the existence of a super-simple (v, 5, 4)-BIBD and show that such a design exi...

We present two new perfect hashing schemes that can be used for efficient bitboard move generation for sliding pieces in chess-like board games without the need to use rotated bitboards. Moreover, we show that simple variations of these schemes give minimal perfect hashing schemes. The new method is applicable provided N , the number of k-bit spaced positions that may be set to 1, is not more t...

In this short article, I build an idea-based growth model with perfect competition in a representative household economy. obtain significant findings that confirm Boitier (2019). First, competitive equilibrium, increasing returns to scale, and innovations can be tenable. For that, firms must raise capital from shareholders, the production function show decreasing scale stock of ideas labor. Sec...

This article presents a model of oligopsony. It considers different conjectural variations that cover the whole range between extreme cases monopsony and perfect competition, such as Collusion, Threat, Cournot, Stackelberg, Bertrand, compares them in terms prices, quantities, profits, mark-down, price elasticity supply welfare. also impact minimum wages, under conjectures analyzed.

In addition to supervision costs, the labor cost of an enterprise (plantation) in the system of slavery consists of the cost of acquiring the slaves and the subsistence compensation given out to the slaves. In this paper, we leave aside the issue of supervision costs previously taken up in the theoretical literature on slavery, and focus on these two peculiar components of labor costs. We analy...

This paper investigates how women leaders in the UK negotiate claims of being competitive by internalizing competition. Competition is a critical component neoliberal contexts; yet its gendered implications are under research. Through analysis 18 leaders' narratives who directly characterize themselves as ‘competitive with myself,’ we theorize and why competition directed at self. We understand...

An (s; n; q; t)-perfect hash family is a set of functions 1 ; 2 ; : : :; s from a set V of cardinality n to a set F of cardinality q with the property that every t-subset of V is injectively mapped into F by at least one of the functions i. The paper shows that the maximum value n s;t (q) that n can take for xed s and t has a leading term that is linear in q if and only if t > s. Moreover, for ...

Abstract This paper investigates efficiency and freedom as joint foundations of market economies. Whereas ideal perfect competition accommodates Mill’s principle individual liberty in the economic arena, real world, imperfectly competitive, markets appear often conflicting values. Building on J. S. utilitarian defense free trade On Liberty Chapter V, this puts forward a consequentialist under i...

IMPERFECT competition is a pervasive part of modern industrial economies, where high levels of concentration in product markets often coexist with unionised labour markets. Most standard macroeconomic models, however, assume that markets are perfectly competitive. This paper provides a simple framework in which we are able to explore some of the implications of imperfect competition for the mac...

Based on the Barings Bank case study from Chapter 1 This case study is found in Chapter 1 of the textbook, but the analysis I present here incorporates ideas from several chapters of the book. Included in the analysis here are the following concepts: Chapter 3: Contracting costs and the existence of firms Chapter 5: Economies of scale and scope Chapter 6: Perfect competition Chapter 10: Asymmet...
