Who are the world's most successful companies?

It seems that everybody wants to know which companies are the most successful. To help throw light on the issue, and to do so more reliably than the plethora of league tables and charts produced by most business magazines, the London Business School have teamed up with The Economist to compile an assessment of the top performers of the 1980's.     

Price rigidities and institutional variations in markets with posted prices

Summary Standard laboratory posted-offer markets respond slowly and incompletely to demand shocks. In these one-sided markets, where sellers control the setting of prices, very little information is transmitted via the process of exchange. For this reason, traders have trouble distinguishing randomness in their own experience from changes in market fundamentals. This paper reports the results of twelve laboratory markets conducted to assess whether some common variants to standard posted-offer rules can correct the adjustment deficiences. Although discounting, multiple postings and excess demand information all improve performance, we find that response remains poor, and efficiencies low.Support for this research was provided by the National Science Foundation (SBR 9319842 and SBR 9320044), and the University of Virginia Bankard Fund.

A comparison of alternative methods of updating input-output coefficients

In recent years there has been a growing number of input-output models of economies ranging in scale from the rural to the national. While offering invaluable insights into the interaction of sectors within an economy, the input-output model suffers from the fact that its coefficient values are altered over time due particularly to technological change. Two of the prominent techniques designed to update these technical coefficients, the RAS and linear programming methods, are compared herein with regard to changes in U.S. national coefficients between 1963 and 1967. Suggestions for improvements to the latter method are outlined.     

Should multivariate early warning systems for banking crises pool across regions?

Most extant work on prediction of banking crises has utilised global samples, which are in turn dominated by observations from middle-income countries, and rely on a single estimator. However, economic and financial structures as well as the pattern of shocks may differ substantially across regions, while a range of specifications is desirable to check robustness. Accordingly, in this paper we test the implicit pooling assumption in earlier multivariate work on Early Warning Systems using both logit and binary recursive tree specifications separately for crises in Asia and Latin America, as well as the pooled sample. Results suggest markedly different crisis determinants across regions, implying global samples are inappropriate.     

Microsoft's AOL北大核心CSSCISSCI

Why the bidding from Redmond has a whiff of anotherfamous tech deal that didn’t go so well.The idea that Microsoft would take Yahoo as its hapless partner has beendiscussed for years down in the Valley.But most of the folks I’ve talked to pret-ty much dismissed it as too wrong tocontemplate. Even Microsoft, dissed byValley Guys as not getting the Web (seeprevious column here), wouldn’t actual-ly go through with it, Yahoo’s decent dowry notwithstanding.

Anatomy of a flipped classroom

A well-designed flipped course requires a significant amount of planning and preparation, but has great benefit to both students and instructor. Using Bloom’s Taxonomy as a guide, one can design effective online and in-class components that maximize benefits to students. A flipped classroom allows students more time to interact with peers and their teacher, and collaborate with teams. This paper will describe how one tourism educator flipped an advanced marketing course, as well as the technology tools used in content creation.
