Essays on Inflation and Output: A Search-Theoretic Approach

Liu, Qian 19 July 2010 (has links)
This dissertation examines the welfare effects of inflation on employment and output in three different market settings. The theoretical frameworks build on recent studies in the monetary search literature that explicitly models the microfoundations of money and study how monetary policy interacts with real variables. The first essay studies the relationship between inflation and unemployment in a general equilibrium framework where inflation has differential effects on employed and unemployed workers. The model finds that inflation can either increase or decrease employment and output, depending on goods and labor market institutions. Sales taxes, the degree of competitiveness in the goods market and imperfect indexation of unemployment insurance benefits are the major factors determining the direction of this relationship. Through a comparison of these parameters, the model predicts an inflation-unemployment relation that is qualitatively consistent with the empirical evidences. The second essay, co-authored with Liang Wang and Randall Wright, investigates the effect of inflation on people's trading behavior in the goods market. By focusing on buyers' search intensity on the extensive margin, the model unambiguously predicts a rise in inflation leads to an increase in the speed with which agents spend their money and velocity. This is consistent with the phenomenon described by the conventional "hot potato" effect of inflation. We also discuss the welfare implications of different monetary policy. In some circumstances inflating above the Friedman rule may be optimal, but the effect of inflation on output is always negative. The third essay, co-authored with Allen Head, Guido Menzio and Randall Wright, examines the effect of monetary growth on output in a general equilibrium model where price stickiness arises as an equilibrium outcome. The model makes several predictions about individual firms' price adjustment behavior that are consistent with micro data. For instance, the frequency (duration) of price changes increases (decreases) with inflation and the price change hazard declines over time. In contrast to the New Keynesian literature, price rigidities in our model does not generate monetary non-neutrality. Higher inflation reduces real output in the long run, but changes in the aggregate price level has no effect on real allocations. / Thesis (Ph.D, Economics) -- Queen's University, 2010-07-17 00:52:41.487

A novel input device for thumb control /

Zaborowski, Philippe S. January 2007 (has links)
This thesis project consists of developing a hand-held, one-thumb input device small enough to be placed on gestural controllers and providing performers with a simple way to select between multiple options with few movements of a thumb. / Most commercial input devices for the thumb make the assumption that buttons are the de facto standard. However, buttons are not always the best solution especially where space is very limited. This project explores a new approach to input design by analyzing the thumb's movements and designing a suitable input device that can track them. The design progression from the first to the last prototype is presented in great detail. / The final prototype is compared to other existing one-thumb input devices used in gestural controllers and mobile computing. The shortcomings of each one-thumb input method is described with the final prototype presented as a possible solution in each case.

Volkswirtschaftliche Effekte außerhäußlicher Kinderbetreuung

Schneider, Ulrike, Luptácik, Mikulás, Schmidl, Barbara January 2006 (has links) (PDF)
Kinderbetreuungseinrichtungen fördern die sozialen Fähigkeiten in der kindlichen Entwicklung in vielerlei Hinsicht, leisten einen wertvollen Beitrag zur vorschulischen Bildung und verbessern die Vereinbarkeit von Beruf und Familie. Die vorliegende Studie fokussierte jedoch nicht auf die viel diskutierte Bedeutung von Kindertageseinrichtungen im gesellschaftspolitischen Bereich, sondern befasste sich mit den Produktions-, Wertschöpfungs- und Beschäftigungseffekten der Kinderbetreuung für die österreichische Volkswirtschaft. Positive Effekte auf die Gesamtwirtschaft resultieren dabei zum einen aus den Investitionen sowie aus dem Verbrauch von Gütern und Dienstleistungen der Kindertagesstätten selbst. Zum anderen fließen die Lohn- und Gehaltsaufwendungen der Kinderbetreuungseinrichtungen zu einem großen Teil dem privaten Konsum zu, was ebenfalls positive Folgeeffekte generiert. Am Beispiel der Wiener Kinderbetreuungseinrichtungen wurden diese Effekte mittels einer Input- Output Analyse quantifiziert. Input-Output Tabellen erfassen systematisch alle Bezugs- und Lieferströme, die zwischen den Wirtschaftsbereichen einer Volkswirtschaft, sowie zwischen Inland und Ausland fließen. So konnten neben den direkten auch die indirekten Wirkungen der wirtschaftlichen Aktivitäten von Kindertageseinrichtungen ermittelt werden, die durch die Nachfrage in anderen Sektoren der heimischen Volkswirtschaft angestoßen werden. Zur Ermittlung der Ausgaben und Investitionen der Wiener Kindertageseinrichtungen wurde eine postalische Befragung durchgeführt, die rund 60 Prozent aller in Wiener Einrichtungen betreuter Kinder erfasste. Volumen und Struktur des Betreuungsaufwandes der übrigen Kinder wurden hochgerechnet. Demnach ging von den Wiener Kindertageseinrichtungen 2004 eine Endnachfrage in der Höhe von mehr als 87 Mio. Euro (Investitions- und Verbrauchsgüter) aus. Zudem wurden 71 Mio. Euro an inländischem Konsum aus den Einkommen der in diesen Einrichtungen beschäftigten ArbeitnehmerInnen ermittelt. Auf dieser Basis wurden folgende gesamtwirtschaftlichen Folgeeffekte ermittelt: Die direkt und indirekt generierten Produktionseffekte der Wiener Kinderbetreuungseinrichtungen beziffern sich auf geschätzte 321 Mio. Euro. Der Produktionsmultiplikator entspricht 2,1 d.h. für jede weitere Million Euro an zusätzlichen Ausgaben der Kinderbetreuungseinrichtungen in Wien erhöht sich die gesamtwirtschaftliche Produktion um etwa 2,1 Mio. Euro. Die direkten und indirekten Wertschöpfungseffekte der Wiener Kindertagesstätten liegen bei 165,5 Mio. Euro. Eine zusätzliche Million an Ausgaben der Wiener Kindertageseinrichtungen erhöht die Wertschöpfung über die gesamte Volkswirtschaft um 1,02 Mio. Euro. Inklusive der direkt in den Betreuungseinrichtungen angestellten Personen sichern Wiener Kindertagesstätten 11.300 rechnerische Vollzeitarbeitsplätze. Der Beschäftigungsmultiplikator beträgt 15, d.h. jede weitere Million an Ausgaben der Kindertageseinrichtungen in der Bundeshauptstadt generiert gesamtwirtschaftlich zusätzliche 15 Vollzeit-Arbeitsplätze. Die in dieser Studie präsentierten Ergebnisse erfassen zwar nur einen Teilbereich aller volkswirtschaftlichen Effekte. So wird in dieser Studie der volkswirtschaftliche Nutzen einer erhöhten Partizipation der Eltern im Erwerbsleben nicht erfasst. Dennoch lassen bereits die vorliegenden Ergebnisse erahnen, welch großes - auch ökonomisches - Potenzial in den Kinderbetreuungseinrichtungen steckt.

Effekten av höghöjdsvistelse på anaerob arbetsförmåga

Lind Forsman, Sanna January 2014 (has links)
Syftet med denna studie var att undersöka om vistelse på hög höjd påverkar den anaeroba arbetsförmågan. Sex aktiva universitetsstudenter, fyra män och två kvinnor, deltog frivilligt i studien. Expeditionen till Nepal varade i 40 dagar och under den perioden sov och vandrade försökspersonerna mellan 1400 och 5100 meter över havet. Före och efter expeditionen genomförde försökspersonerna ett anaerobt wingatetest där peak power, average power, minimum power and power drop uppmättes. Resultatet visade en signifikant sänkning av average power efter den genomförda expeditionen på hög höjd, med ett medelvärde på 8.44 ± 0,84 w/kg före expeditionen och 7.81 ± 0,87 w/kg efter expeditionen. Inga signifikanta förändringar sågs hos övriga uppmätta parametrar. Konklusionen är att average power försämras efter 40 dagars vistelse på hög höjd.

Natural resource content of foreign trade and structural bias : an inter-country comparison of Czechoslovakia and Austria by means of input-output technique

Drabek, Zdenek January 1983 (has links)
The purpose of this study is to test the hypothesis that centrally- planned economies are characterized by what is called a bias towards absorption of natural resource intensive products (NRP) which is said to affect in turn the commodity structure of their foreign trade. While the study includes a detailed analysis of foreign trade structures and the absorption of NRP by final consumers, it is the intermediate demand for NRP and its determinants which are emphasized. Following the suggestions in the literature that the technologies used by the centrally- planned and market-type economies are different, the role of technology in determining intermediate demand for NRP has been examined in detail. Bias is defined here in terms of inter-country differences and the present comparison involves a case-study of Czechoslovakia as a centrally-planned economy and Austria as a market-type economy based on an input-output model. The use of the input-output model in inter- national comparisons of production and use of commodities has been criticized on the following grounds: (1) The distinction between technology and substitution is ignored in the model. (2) International differences in relative prices are normally ignored or assumed away in empirical work. (3) The comparisons may be severely affected by imperfections of input-output tables. This study attempts to answer the above criticism in an original way. New methods of sensitivity analysis were designed to test for the existence of the 'triangular' and other 'fundamental' properties of the technological matrices. In addition, the assumption of temporal stability of input-output coefficients is relaxed and an attempt is made to distinguish between technology and substitution with the help of the RAS method. Further analysis of the impact of relative prices on input-output flows was derived from an analysis of indirect taxation. The main conclusion of this study is that Czechoslovakia had a considerable NRP import bias which was primarily due to the pro-NRP absorption bias of final consumers. However, it is unlikely that 'excessive' aggregate demand for imports originated in 'NRP-biased' technology. This empirical analysis provides strong evidence that the production processes with regard to the use of NRP were highly similar in both countries.

Structural evolution of environment and economy in Australia

Wood, Richard January 2009 (has links)
Doctor of Philosophy (PhD) / The purpose of this research is to help understand the key relationships in an evolving economic structure that are driving resource use and greenhouse gas emissions in Australia. The approach involves looking at the factors and relationships that underpin economic growth in Australia. This research seeks to understand the changes in these factors by taking a historical perspective to the determinants of environmental impact through an investigation of structural changes over a period of 30 years. A detailed model is developed using the macro-economic tool of input-output analysis. This model makes it possible to investigate inter-relationships and intra-relationships between sectors of the environment, the economy and the population at disparate scales.
