Tax Toleration and Tax Compliance: How Government Affects the Propensity of Firms to Enter the Unofficial Economy

We propose a model of how government-supplied institutional benefits and the taxation and regulation of producers affect the propensity of private firms to enter the unofficial economy and evade taxation. Our analysis implies that the incentive of firms to produce underground depends on tax rates relative to firmspecific thresholds of tax toleration that are decisively affected by quality of governance — in particular by the presence of high-grade institutions delivering services that profit-maximizing firms deem worth paying for. Some key predictions of the model concerning the determinants of firms’ tax toleration and tax compliance receive broad support from empirical analyses of enterprise-level data from the World Bank’s World Business Environment Surveys.-

Extremely low frequency based communication link

The paper discusses the literature review and the possibility of using the ground itself as transmission medium for various users’ transceivers and an administrator transceiver using Multi-Carrier-Direct Sequence-Code Division Multiple Access (MC-DS-CDMA), Orthogonal Frequency Division Multiplexing (OFDM),16-Quadrature Amplitude Modulation (16-QAM), Frequency Division Duplex (FDD) and Extremely Low Frequency (ELF) band for the applications of Oil Well Telemetry, remote control of power substations or any system that its responding time is not critical

Sovereign illiquidity and recessions

Motivated by the striking increase in sovereign spreads and the subsequent recession in Europe during 2011, I examine the importance of sovereign debt liquidity in a New Keynesian environment with wage rigidities and nancial frictions a la Kiyotaki and Moore (2012). My main ndings imply that, independently of credit risk, a decrease in the liquidity of government bonds has signi cant detrimental e ects on output, employment, investment, and equity prices. Therefore, this framework suggests that ECB policies taken in 2012 aimed at introducing liquidity seem to be the desired measures, at least temporally until conventional monetary policy became e ective again

OPTIMIZATION OF LIGHTWEIGHT TORPEDO ALLOCATION

When making torpedo loadout decisions, planners must consider the capacities and capabilities of different ASW units, a limited budget, and diverse adversary submarine fleets. Currently, loadout decisions for the Mk-54 lightweight torpedo are made manually, and without a systematic approach to deal with threat uncertainty. The thesis seeks to inform these decisions by using stochastic optimization to determine the type and quantity of torpedoes to loadout to U.S. surface ships, fixed-wing aircraft, and helicopters in order to face an uncertain submarine threat with a desired probability of kill. We develop two formulations of the Torpedo Allocation Stochastic Optimization Model (TASOM): TASOM-1, which minimizes the number of missed submarines; and TASOM-2, which minimizes the deviation below the probability of kill threshold. To show the value of the stochastic programming approach over the typical deterministic planning, we present a notional case designed to represent an operation where ASW units are patrolling an area for adversary submarines. We randomly generate 100 threat scenarios where the number and class of submarines deployed to the area vary. The TASOM-2 loadout notably outperforms the deterministic average loadout. Our models combined with an accessible user interface provide planners with a decision aid tool to conduct sensitivity analysis to guide torpedo allocation and budget decisions under uncertainty.Outstanding ThesisLieutenant, United States NavyApproved for public release.

Effect of silver on the phase transition and wettability of titanium oxide films

The effect of silver on the phase transition and microstructure of titanium oxide films grown by pulsed cathodic arc had been investigated by XRD, SEM and Raman spectroscopy. Following successive thermal annealing up to 1000 °C, microstructural analysis of annealed Ag-TiO2 films reveals that the incorporation of Ag nanoparticles strongly affects the transition temperature from the initial metastable amorphous phase to anatase and stable rutile phase. An increase of silver content into TiO2 matrix inhibits the amorphous to anatase phase transition, raising its temperature boundary and, simultaneously reduces the transition temperature to promote rutile structure at lower value of 600 °C. The results are interpreted in terms of the steric effects produced by agglomeration of Ag atoms into larger clusters following annealing which hinders diffusion of Ti and O ions for anatase formation and constrains the volume available for the anatase lattice, thus disrupting its structure to form rutile phase. The effect of silver on the optical and wetting properties of TiO2 was evaluated to demonstrate its improved photocatalytic performance

Conformación de una estrategia para la revolución socialista en Argentina: Partido Revolucionario de los Trabajadores (1965-1970)

En el presente artículo analizamos el proceso de conformación de la estrategia de lucha armada del Partido Revolucionario de los Trabajadores (PRT) entre los años 1965 y 1970. Las fuentes analizadas son publicaciones de la propia organización: el periódico La Verdad (1965-1968), los documentos del IV y V Congreso partidario y el periódico El Combatiente (1968-1970). En las fuentes mencionadas rastreamos las tradiciones políticas reivindicadas por el PRT, los sucesos históricos contemporáneos que la organización adoptó como hitos fundantes y la definición de su estrategia de lucha. En particular, nos detendremos en comprender la fundamentación política que ofrece el propio PRT para su estrategia de guerra civil revolucionaria; la combinación de la vía armada con otras formas de luchas; los debates con otras fuerzas de izquierda; las conclusiones extraídas a partir de los azos; las relaciones campo-ciudad y la concepción de poder dual

Lattice Gas Dynamics; Application to Driven Vortices in Two Dimensional Superconductors

A continuous time Monte Carlo lattice gas dynamics is developed to model driven steady states of vortices in two dimensional superconducting networks. Dramatic differences are found when compared to a simpler Metropolis dynamics. Subtle finite size effects are found at low temperature, with a moving smectic that becomes unstable to an anisotropic liquid on sufficiently large length scales.Comment: 5 pages, 4 figure

A geological model for the management of subsurface data in the urban environment of Barcelona and surrounding area

The overdevelopment of cities since the industrial revolution has shown the need to incorporate a sound geological knowledge in the management of required subsurface infrastructures and in the assessment of increasingly needed groundwater resources. Additionally, the scarcity of outcrops and the technical difficulty to conduct underground exploration in urban areas highlights the importance of implementing efficient management plans that deal with the legacy of heterogeneous subsurface information. To deal with these difficulties, a methodology has been proposed to integrate all the available spatio-temporal data into a comprehensive spatial database and a set of tools that facilitates the analysis and processing of the existing and newly added data for the city of Barcelona (NE Spain). Here we present the resulting actual subsurface 3-D geological model that incorporates and articulates all the information stored in the database. The methodology applied to Barcelona benefited from a good collaboration between administrative bodies and researchers that enabled the realization of a comprehensive geological database despite logistic difficulties. Currently, the public administration and also private sectors both benefit from the geological understanding acquired in the city of Barcelona, for example, when preparing the hydrogeological models used in groundwater assessment plans. The methodology further facilitates the continuous incorporation of new data in the implementation and sustainable management of urban groundwater, and also contributes to significantly reducing the costs of new infrastructures.Peer ReviewedPostprint (published version

AUTOESTIMA Y MANEJO DE LA TENSIÓN COMO VARIABLES DE CONCORDANCIA PARA ESTABLECER ESTRATEGIAS DE APOYO A ESTUDIANTES DEL NIVEL MEDIO SUPERIOR.
