Full textThis thesis presents three essays in macroeconomic theory. The first chapter surveys monetary models with heterogeneous agents and contains an evaluation of heterogeneous welfare costs of inflation when agents have different income and wealth levels. The second chapter studies the interactions between two transmission channels of monetary policy that arise because of heterogeneity: the nominal debt channel and the inflation-tax net worth channel. The third chapter studies the relations between expectations of future output growth of a small open economy and sovereign defaults. This essay shows that learning of the stochastic process that drives debt sustainability induces significant debt volatility and an empirically plausible default frequency.

Full textThe taxation of financial income, typically those arising from the investment of the savings of individuals, is of fundamental importance in tax policy of advanced countries in both domestic perspective (requirements of revenue, contrast elusive phenomena, etc..) and external perspective (especially with the implementation of defensive or aggressive policies to avoid the risk of escape and to facilitate the attraction of capital.) The models of taxation of such income are different from those applicable to "direct savings" and those applicable to "savings intermediated": the two sectors have different issues and aspects, but without interruption since the tax discipline of the "savings intermediated" cannot ignore in any case the recognition of the tax provisions of the "direct savings." The main objective of the work was made therefore to analyze the peculiarities of our system of taxation of financial income, current problems, mainly due to the discontinuity of the system, and any possible changes therein. In particular, it was done previously to recognition of different forms of employment in financial activities of the wealth of Italians also analyzing the composition of tax revenue derived from "investment income", which are an ideal "income fund" in that group are due two of the six categories of incomes provided by the Italian “TUIR”: capital gains and other income of financial nature. As known, there is not a paradigmatic definition of the mentioned income categories, for both, in fact, the Italian “TUIR” provides a list , which includes precise and stringent cases of financial incomes relevant for tax purposes ; abstractly, you can bring the abstract category of income the concept of capital-income products (ie those revenues which were the result - civil or economic interests as such as dividends - resulting from the capital) and capital gains of a financial nature to the concept of income-entry (ie those income, also differential, where the shop exists but use of capital does not arise as a direct result of the production proceeds thereof). With particular reference to the interests - that constitute the income of capital for excellence, together with dividends - has also shown that, from an accounting point of view and in a perspective of corporate taxation, these proceeds are comparable to all other costs while under a more strictly microeconomic, the same are in fact an income and, therefore, differ from ordinary charges for factors of production. From the perspective of economic theory of the remuneration of production factors, in fact, the interest is, in a sense, comparable to wages and profits. Therefore, even if at the macro-economic interests - unlike income from production activities in the strict sense - not contribute to the formation of national income (GDP) being a breakdown in the form of annuity, the national economic value added. Another salient theme is that the measure in the rate of taxation of financial income that assumes central importance in our tax system, where such income received by individuals outside the exercise of business activities, usually are not taxed as other income through progressive taxation but undergo a proportional levy replacement. Most of the cases in financial income is in fact assessed at 12.50%, which may seem rather modest and, therefore, from many it expects a rise. However, one must consider that much of the financial performance of the recovery is not income but capital eroded by inflation. In other words, the yield from the securities is, first, to preserve the purchasing power of invested capital in the sense that one can speak of a real income only if it manages to cover inflation, otherwise determines a loss of real capital. Therefore, the decision remained at a relatively low rate, given the nominalistic criterion of our tax system that provides indexing, grants a kind of compensation to offset the disadvantage of inflationary erosion. It was also revealed that the "success tax" of financial income is largely attributable to the low level of tax rate but also the role of intermediaries will be responsible for all (or almost) instrumental and procedural requirements intended for the performance tax obligations. It 's obvious fact, the central role of intermediaries-"great debt" in the system for taxation of financial income, both in the application of withholding tax or capital gains tax replacement under both regimes of savings managed and operated for the taxation of income, other financial in nature (schemes to which you have given wide coverage in the discussion). As correctly noted in the literature, the broker "provide a certain security of investment, but tax the income in a kind of apotheosis of corporate taxation, which sees very occasional action of a fiscal intermediaries who trusts completely, usually with reason. In contrast, income earned outside of these structures, private companies and private or unstructured, are usually hidden from the tax. " Financial intermediaries involved in the taxation of investment income – paying directly or indirectly income to various stakeholders (ie employees, consultants, shareholders, customers, etc..) and, as a tax substitute, making withholding source as an advance od'imposta and substitute taxes on investment income and all consequences arising from compliance-related equipment - represent the case of more rigid corporate-administrative organization; they are, in fact, operators of large or very large sizes, making use of standardized procedures, complex and are subject to a number of internal and external controls. It is therefore clear that the taxation of capital gains, made through CDs "Large taxpayers", is the excellence of corporate taxation, as the "financial wealth" is channeled and taxed through banking and other financial firms. However, the current system of taxation of financial income, as fairly efficient is not uniform and sometimes is not neutral, thus highlighting the scope for improvement. This refers, among others, the "mismatch" represented by the existence of a double (triple, actually) the level of tax rates, the difference in timing of the taxation of Italian investment funds (taxed under the income accruing) and of investment funds harmonized Community (taxed at realization) and the different characteristics of different systems of taxation of savings. Pending the increasing importance of international capital mobility, it was decided to also analyze briefly the treatment of transnational financial income and outgoing (outbound incomes) and incoming (inbound incomes).

Full textIl paradigma inflazionario rappresenta una modo affascinante ed elegante di spiegare alcuni cruciali fenomeni cosmologici; inoltre risulta in notevole accordo con le attuali osservazioni cosmologiche. Tuttavia, diversi aspetti della fisica di tale processo risultano ancora oscuri e una prova inequivocabile di tale meccanismo è ancora assente. Dall'altro lato, il meccanismo inflazionario si presenta come soluzione di problemi cosmologici ancora aperti, come l'osservazione di campi magnetici nel mezzo intergalattico. Per studiare in profondità il meccanismo inflazionario, una possibilità è offerta dalla nuova epoca di esperimenti per l'osservazione di onde gravitazionali. La prima parte della tesi è focalizzata su tale aspetto della fisica inflazionaria. Ciascun modello inflazionario predice la produzione di un fondo stocastico di onde gravitazionali (modo tensoriali) dovuti alle fluttuazioni quantistiche del campo gravitazionale. Inoltre, in alcuni scenari, la presenza di ulteriori campi oltre all'inflatone e al campo gravitazionale, genera efficaci sorgenti di onde gravitazionali, attivando la produzione classica. Il segnale di onde gravitazionali inflazionarie si rivela essere una unica e interessante finestra sull'origine e l'evoluzione dell'universo, e la possibilità di investigare la sottostante teoria della gravità. Nella tesi è mostrato il ruolo significativo delle onde gravitazionali primordiali nel testare il meccanismo inflazionario in sè e nel provare diversi aspetti della fisica inflazionaria, sfruttando la validità/violazione di una relazione di consistenza. Essendo le onde gravitazionali inflazionarie, un modo promettente di esplorare diversi aspetto della fisica dell'universo primordiale, è inoltre fornito un quadro aggiornato dello stato attuale e delle prospettive di osservazione dei modi tensoriali inflazionari, con una focalizzazione particolare sulla possibilità di osservazione diretta offerta dagli interferometri laser. Successivamente, sono esposte delle previsioni sulle possibilità offerte dell'interferometro spaziale LISA rispetto al testare la fisica inflazionaria. Nella seconda parte della tesi viene descritto un altro aspetto interessante della fisica inflazionaria, ovvero la possibilità di una significativa magnetogenesi. Le osservazioni di raggi gamma dai blazars indicano la presenza di campi magnetici nel mezzo intergalattico, dove non è presente plasma carico. Questo fatto suggerisce un'origine primordiale di tali campi magnetici. E' interessante notare che il meccanismo inflazionario fornisce un affascinante modo di spiegare la presenza di campi magnetici a scale cosmologiche. In una sezione dedicata, sono mostrati i principali modelli di magnetogenesi inflazionaria. Un aspetto comune di tale modelli è una sovra produzione di perturbazioni di curvatura e tensoriali, rispetto al modello inflazionario di single-field slow-roll. In generale, i limiti osservativi ottenuti da misurazioni di CMB su tali quantità comportano restrizioni significative sulla produzione di campi magnetici associata. Altri limiti sono imposti dal controllo della backreaction dei campi elettromagnetici. In particolare, nella tesi viene considerato il modello proposto da Caprini, in cui ha luogo una magnetogenesi in grado di spiegare le attuali osservazioni dei raggi gamma e di dare inizio al processo di dynamo galattica. Viene calcolata la correzione allo spettro e bispettro degli scalari rispetto al caso di single-field slow-roll, in tale scenario. Il risultato mostra come le restrizioni più forti siano dovute alla non osservazione di un bispettro degli scalari nelle anisotropie della CMB. Ciò nonostante, si conclude che anche quando tali restrizioni vengono prese in considerazione, lo scenario inflazioanrio in esame fornisce una robusta spiegazione dei campi magnetici osservati per una ragionevolmente alta scala di energia dell'inflazione.

Full textThe Ph.D. thesis consist of three chapters on evaluating inflation dynamics in Georgia and modeling and forecasting nominal exchange rates for the European Eastern Partnership (EaP) countries using modern applied econometric techniques. In the first chapter, we survey of models those produce high predictive powers for forecasting exchange rates and inflation. This survey reveals that the factor-based and time-varying parameter (TVP) models generate superior forecasts relative to all other models. In the second chapter, we study inflation dynamics in Georgia using a hybrid New Keynesian Phillips Curve (NKPC) nested within a time-varying parameter (TVP) framework. Estimation of a TVP model with stochastic volatility shows low inflation persistence over the entire time span (1996-2012), while revealing increasing volatility of inflation shocks since 2003. Moreover, parameter estimates point to the forward-looking component of the model gaining importance following the National Bank of Georgia (NBG) adoption of inflation targeting in 2009. In the third chapter, we construct Factor Vector Autoregressive (FVAR) models to forecast nominal exchange rates for the EaP countries. This study provides better forecasts of nominal exchange rates than those produced by the random walk process.
