HOW IMPORTANT ARE CAPITAL AND TOTAL FACTOR PRODUCTIVITY FOR ECONOMIC GROWTH?

We examine the relative importance of the growth of physical and human capital and the growth of total factor productivity (TFP) using newly organized data on 145 countries that spans more than 100 years for 23 of these countries. For all countries, only 14% of average output growth per worker is associated with TFP growth. We use priors from theories to construct estimates of the relative importance of the variances of aggregate input growth and TFP growth across countries. Much of the importance of the variance of TFP growth across countries is associated with negative TFP growth. (JEL O47 , O50 , O57 , O30 , N10 )     

Using WhatsApp for a homeless count

The study analyses how the use of instant messaging (WhatsApp) alongside other ICT tools is adequate to complement the count of homeless people in an area. In particular, it describes the methodology used in order to organize the first official count of homeless people in Girona (Catalonia, Spain). Given that this is the first count of individuals experiencing homelessness in the city, it is difficult to say that it is an improvement, but it could be suggested that the app might make the future counts more efficient. Both professional and volunteers and homeless people used WhatsApp to send information. A total of 283 homeless people were detected. Results show that the usage of this application optimized the results of the count. 36.1% of the data were obtained online. Homeless people, who were reluctant to contact directly with the professional team, used WhatsApp to communicate with them, adding up to 19.4% of the data obtained. Results show how communication between homeless people and health and mental health services can be potentially improved with this type of application.     

NFL Draftnikology: Euclidean Metrics and Other Approaches to Scoring Ranking Predictions

With viewership of NFL (National Football League) football in the US rising above 20 million, interest in the NFL Draft has also been at all-time highs in recent years. Much of this interest is directed toward the “NFL draftniks” who provide draft predictions—so-called “mock drafts”—leading up to the NFL Draft. Despite increasing interest in “NFL draftnikology,” the scoring methodology used to evaluate mock NFL drafts lags far behind. This study offers a few alternative approaches, including a Euclidean metrics approach to evaluating mock NFL drafts. The usefulness of our methodologies extends to evaluation of economic and financial analysts.     

THE IMPACT OF TELEVISED SPEECHES AND FOREIGN TRAVEL ON PRESIDENTIAL APPROVAL

Considerable attention has been devoted in recent years to theuse of political drama by the president, with the most discretionaryforms of drama—speeches and foreign travel—receivingmuch scrutiny. In fact, there has arisen a conventional wisdomwhich asserts that televised speeches and foreign travel bythe president (1) have increased over time, (2) exert a uniformlypositive impact on public evaluations of the president's performance,and (3) can therefore be used as a strategy for influencingthe president's approval ratings, a vital resource for the modernpresident. The purpose of this paper is to evaluate this conventionalwisdom and thus assess the value of televised speeches and foreigntravel as influences on presidential approval. The paper firstdefines political drama and casts the conventional wisdom inthe form of three propositions. It next develops a researchstrategy for evaluating these propositions in an appropriatemanner. Finally, the paper tests the propositions. The resultscast considerable doubt on the conventional wisdom and leadto the conclusion that the use of political drama is not anall-purpose strategy guaranteed to halt declines or replenishsizable losses of presidential approval.     

A COMPARISON OF THE VIABILITY OF MAIL SURVEYS IN JAPAN AND THE UNITED STATES

A comparison of response rates and patterns to a mail surveyconducted simultaneously on random samples drawn from telephonelistings in Seattle, Washington, and Kobe, Japan, is presented.When undeliverable surveys (those for which the intended respondenthad moved or passed away) are subtracted from the original samples,a comparison of the differences in the response rate percentagesfor the two countries is found to be statistically insignificant.Adherence to the theoretical foundation of the Total DesignMethod is claimed to be the principal reason for success inachieving a higher response rate than predicted by Japanesescholars to the mail survey in Japan. These results show thatthere is potential for adapting survey research techniques developedin the United States to non-Occidental settings.     

Comparing products using data envelopment analysis

Using an application of linear programming known as Data Envelopment Analysis (DEA), a method is described to compare products which vary in excellence along a number of dimensions, and for each of which there might be a number of associated “costs”. The method is illustrated by comparing published benchmarks of 37 computer printers. Potential uses of a DEA analysis of products might be: to assist corporate buyers who may need to reconcile a diversity of present and future uses in one standardised purchase; in competitor analysis; in determining unexplored market niches; and as a normative model of product excellence against which product purchasing behaviour could be compared.
