Abstract:
Abstract This paper investigates the dynamic linkages between the prices of crude oil, biofuels and agricultural commodities. The analysis uses monthly data for crude oil, corn, sugar, ethanol, biodiesel and the general food price index and covers the period 1960 –2013. In the context of the empirical analysis, we apply the ARDL approach to cointegration, in conjunction with Granger causality tests. The results reveal strong dependencies between the examined sectors in both the long and short run time horizon. JEL classifications: C22, C52, Q11, Q42, Q43 Keywords: ARDL Cointegration, Agricultu

Abstract:
In this paper, I try to shed some new light on the “puzzle” of why the Lucas critique, believed to be important by most economists, seems to have received very little empirical support. I use a real-business-cycle model to verify that the Lucas critique is quantitatively important in theory, and to examine the properties of the super-exogeneity test, which is used to detect the applicability of the Lucas critique in practice. The results suggest that the superexogeneity test is not capable of detecting the relevance of the Lucas critique in practice in small samples. (JEL C52, C22, E41)

Abstract:
We discuss a procedure for seasonality analyses of short time-series data with small amplitude. Such analyses are often performed in medical research. In economics, however, time series are typically long and of appreciable amplitude; therefore, economists are used to analyzing such data. Our procedure provides one more tool for the economists’ data-analysis toolbox. We illustrate the procedure’s application with three examples of real economics data. The examples demonstrate that the procedure can be profitably applied to short economics time series. JEL Classifications: C12, C22, C23, C49, F

ABSTRACT Accounting studies often encounter observations with extreme values that can influence coefficient estimates and inferences.

The classical approach to testing for structural change employs retrospective tests using a historical data set of a given length.

Procedures based on estimates of the regression coefficients are extended in three directions: we introduce (a) procedures based on OLS residuals, (b) rescaled statistics and (c) alternative asymptotic boundaries

We consider the class of two-player symmetric n x n games with the total bandwagon property (TBP) introduced by Kandori and Rob (1998). We show that a game has TBP if and only if the game has 2^n - 1 symmetric Nash equilibria. We extend this result to bimatrix games by introducing the generalized TBP. This sheds light on the (wrong) conjecture of Quint and Shubik (1997) that any n x n bimatrix game has at most 2^n - 1 Nash equilibria. As for an equilibrium selection criterion, I show the existence of a ½-dominant equilibrium for two subclasses of games with TBP: (i) supermodular games; (ii) po

Abstract:
We provide a flexible means of estimating time-varying parameter models in a Bayesian framework. By specifying the state innovations to be characterized trough a threshold process that is driven by the absolute size of parameter changes, our model detects at each point in time whether a given regression coefficient is constant or time-varying. Moreover, our framework accounts for model uncertainty in a data-based fashion through Bayesian shrinkage priors on the initial values of the states. In a simulation, we show that our model reliably identifies regime shifts in cases where the data genera

Abstract:
Dynamic covariance estimation for multivariate time series suffers from the curse of dimensionality. This renders parsimonious estimation methods essential for conducting reliable statistical inference. In this paper, the issue is addressed by modeling the underlying co-volatility dynamics of a time series vector through a lower dimensional collection of latent time-varying stochastic factors. Furthermore, we apply a Normal-Gamma prior to the elements of the factor loadings matrix. This hierarchical shrinkage prior effectively pulls the factor loadings of unimportant factors towards zero, ther

Several recent empirical studies, particularly in the regional economic growth literature, emphasize the importance of explicitly accounting for uncertainty surrounding model specification.

ZusammenfassungDie Beherbergungsbetriebe sind ein zentraler Faktor des Tourismusangebots, weil – sieht man von Camping- und Zeltplätzen ab – ohne entsprechendes Bettenangebot ein Großteil des Tourismus praktisch nicht stattfinden kann. Mit dem Wachstum des internationalen Tourismus steigt auch die Zahl der Beherbergungsbetriebe und der verfügbaren Betten. Weltweit gab es im Jahr 2018 geschätzte 119 Mio. Betten in kommerziellen Beherbergungsbetrieben (extrapolierte Daten aus Gössling und Peeters 2015), d. h., Angebote in der neuen Plattformökonomie (z. B. durch Airbnb) kommen noch dazu. Die Beherbergung verursacht einen wesentlichen Teil der touristischen Treibhausgasemissionen. Eine Schätzung geht davon aus, dass pro Übernachtung im weltweiten Durchschnitt etwa 14 kg CO2 entstehen (direkte Emissionen der Beherbergung, ohne Gastronomie; Gössling und Peeters 2015). Die Emissionsbandbreite der in der Literatur dokumentierten Werte schwankt allerdings je nach Unterkunftsform zwischen 0,1 kg CO2 und 260 kg CO2 pro Nacht (Gössling 2010). Eine Berechnung von Lenzen et al. (2018) geht davon aus, dass pro Jahr Treibhausgasemissionen von 282 Mt CO2-Äquivalenten durch Beherbergungsbetriebe verursacht werden (Input-Output-Analyse, ohne Gastronomie).

Abstract:
At the end of the Cretaceous the Appalachian Mountains had undergone 180 m.y. of erosion since their principal uplift in the Middle Pennsylvanian through the Late Permian (300-250 Ma), but they were higher and more rugged than at present and provided a somewhat more diverse vertically zoned array of habitats. In contrast, the Rocky Mountains were only ~1 km above sea level at 65 Ma; the Coast Ranges, Sierra Nevada, and Cascade Mountains would not attain substantial heights until late in the Tertiary. Computer models in the NM mode, which simulate conditions in western North America in the Late Cretaceous, show a nearly continuous westerly jet stream with relatively small amplitude between the troughs (lowpressure systems) and ridges (high-pressure systems). The present north-south seasonal meandering of the jet stream was also less. Thus, in the models precipitation and temperatures were more uniform throughout the year and there was less regional differentiation in climate. CO2 concentrations during the Cretaceous are estimated to have been 4-8 times to 10-12 times higher than at present. With a 2-5°C warming for each doubling of CO2, this provides part of the explanation for the higher MAT documented for the Late Cretaceous and Early Tertiary. High CO2 concentrations near the end of the Cretaceous may have been a holdover from earlier intense volcanism in the South Pacific that began to subside at ~ 100 Ma. The term epeirogeny refers to vertical motions of the Earth’s crust, and these movements affect the ocean floor, as well as the continents. There was a 50% increase in the production of ocean crust in the Middle Cretaceous compared to earlier times, as represented by the early Aptian Ontong Java Plateau, the Earth’s largest oceanic plateau, now submerged over 2 km off the Solomon Islands. A sense of the magnitude of this structure can be gained by comparing its volume with that of the surface-exposed Deccan Traps of India (66 Ma). The latter are ~1 km thick and have a volume of 1.5 x 106 km3. The Ontong Java Plateau is ~36 km thick and has a volume of 50 x 106 km3.

Abstract:
Sammenlignbarhet er en ønsket kvalitet ved finansregnskapet, og IASB referer hyppig til denne kvaliteten i sitt arbeid med utvikling av IFRS. Men sammenlignbarhet er et vanskelig konsept å forstå (Zeff, 2007), og forskning viser at det er vanskelig å måle (De Franco et al., 2011). I dette kapitlet analyserer jeg IASBs bruk av konseptet. IASB legger stor vekt på konsistens, spesielt for at like ting skal fremstå som like, men IASB søker også å utvikle standarder som er tilstrekkelig robuste til at ulike ting skal fremstå som ulike. Samtidig baserer IASB sin argumentasjon delvis på uuttalte forutsetninger uten å drøfte hva som gjør ting like og ulike. Analysene i kapitlet indikerer at IASB refererer til konseptet vel så mye for å skape inntrykk av kvalitet i standardene som for å gi reell begrunnelse for valgte løsninger.

Abstract:
The steady rise in cooling requirements of commercial computer products mandates the development of aggressive thermal management techniques, as well as accurate design and analysis methodologies. Single phase direct liquid jet impingement, offers a controlled high performance alternative, by eliminating the need for a thermal interface, and by delivering the coolant directly to the surface of the chip. This paper characterizes the thermal performance of a specific direct liquid jet impingement scheme in which the hot fluid exhausts via return vents located in the immediate vicinity of the jet

Abstract:
The accidental leakage is one of the main risks in supercritical CO2 power conversion system. Complex leakage behavior including critical flow and multiphase jet flow occurs at the leak, which need to be evaluated carefully for safety assessment before deployment of supercritical CO2 power conversion system. A new experimental facility was built to study supercritical CO2 leakage flow. The critical flow and jet flow behavior of supercritical CO2 through short tubes were experimentally investigated. Six sharp-edged short tubes with length between 1.0 and 15.0 mm and diameter of 1.0mm were teste

Abstract:
Jet impingement cooling with phase change has shown the potential to meet the increased cooling capacity demands of high-power-density (of order 100 W/cm2) automotive electronics components. In addition to improved heat transfer, phase change cooling has the potential benefit of providing a relatively isothermal cooling surface. In the present study, two-phase jet impingement cooling of multiple electronic devices is investigated, where the fluorinated dielectric fluid HFE-7100 is used as the working fluid.

Abstract:
Jet/spray cooling is a way of efficiently removing heat from a hot surface like in the back plate for high power electronic devices. In the present work, a close loop liquid jet/spray setup with a novel effluent/spent liquid removal system is established for large area cooling. A 4×4 nozzle array is used to generate the spray/jet targeting the heat source area of 4 (2×2) cm2. Flourinert FC-72™ is used as coolant liquid. The thermal performance data for multi-jet/spray cooling in a closed and confined system are obtained at various liquid temperatures and flow rates. The experimental work illus

Abstract:
MEMS-based microchannel heat sinks are being investigated at the Jet Propulsion Laboratory (JPL) for use in micro/nano spacecraft thermal control. The current stage of development focuses on the integration of microchannel heat sinks into spacecraft pumped cooling loops. Two microchannel heat sinks, adapted from a Stanford University Microfluidics Laboratory design, were fabricated at JPL and tested for thermal and hydraulic performance in a single-phase pumped cooling loop. The first microchannel heat sink design was demonstrated to remove heat fluxes of up to 25 W/cm2 with a maximum device t

Abstract:
In the present paper, the synergistic combination of inter-cooling with pulsed detonation combustion is analyzed concerning its contribution to NOx and CO2 emissions. CO2 is directly proportional to fuel burn and can, therefore, be reduced by improving specific fuel consumption and reducing engine weight and nacelle drag. A model predicting NOx generation per unit of fuel for pulsed detonation combustors, operating with jet-A fuel, is developed and integrated within Chalmers University’s gas turbine simulation tool GESTPAN. The model is constructed using CFD data obtained for different combust

We present highly resolved large eddy simulation (LES) of a realistic effusion cooling geometry. The test case features mixing between a high-density working fluid (CO2) and a low-density crossflow (air) to mimic the density stratification in typical gas turbine cooling flows. The coolant CO2 is fed from a plenum into the air channel through a series of 52 inclined orifices in a staggered arrangement. Highly detailed LES computations presented in this study resolved entire 52 cooling holes to accurately capture realistic jet-to-jet interactions which are critical in cooling film formation. Two
