A Methodology to Detect the Deviations of the Project s Budget Compared to Market Prices
2015
[EN] The budget of a project reflects the cost of the investment needed to build an infrastructure, install a system or acquire new materials or supplies. A well-formulated budget in accordance with market prices, allows contractors to prepare offers according to their technical, economic and financial characteristics. On the other hand, it avoids current philosophies that aim to get the contract at any price. Philosophies subsequently used to point out problems and claims during the execution of the project (contradictory prices, delays, etc.) in order to recover some or the entire economic bid carried out during the tendering. In this paper a simple and fast methodology is developed to ch…
Corporate Investment, Debt and Liquidity Choices in the Light of Financial Constraints and Hedging Needs
2015
We examine firms' simultaneous choice of investment, debt financing and liquidity in a large sample of US corporates between 1980 and 2014. We partition the sample according to the firms' financial constraints and their needs to hedge against future shortfalls in operating income. In contrast to earlier work, our joint estimation approach shows that cash flows affect the corporate decisions of unconstrained firms more strongly than those of constrained firms. Investment-cash flow sensitivities are particularly intense for unconstrained firms with high hedging needs. Investment opportunities (as proxied by Q), however, play a larger role for constrained firms with the effects being strongest…
Joan Robinson and Keynes: finance, relative prices and the monetary circuit.
2003
Joan Robinson's views on credit and money are discussed only rarely. Of late, however, some Post-Keynesians have sought to revive these views, claiming that Robinson was one of the original contributors to the theory of endogenous money, post Keynes. This paper has two objectives. First, it seeks to develop Robinson's views on credit, money and finance and to show that not only did she have a clear understanding of the theory of endogenous money, but that she also held views akin to the theory of the monetary circuit. Second, the paper addresses Robinson's dismissal of the problem of relative prices and the conventional theory of value. Once again, it shows that Robinson's position is conne…
Extreme value theory versus traditional GARCH approaches applied to financial data: a comparative evaluation
2013
Although stock prices fluctuate, the variations are relatively small and are frequently assumed to be normally distributed on a large time scale. But sometimes these fluctuations can become determinant, especially when unforeseen large drops in asset prices are observed that could result in huge losses or even in market crashes. The evidence shows that these events happen far more often than would be expected under the generalised assumption of normally distributed financial returns. Thus it is crucial to model distribution tails properly so as to be able to predict the frequency and magnitude of extreme stock price returns. In this paper we follow the approach suggested by McNeil and Frey …
Fair Planning and Affordability Housing in Urban Policy. The Case of Syracuse (Italy)
2016
Equalization can be implemented in the planning process by means of several tools. The Syracuse’s Master Plan has used “urban negotiation” to obtain land for facilities and public infrastructure in different urban areas basing on the rule of the transfer of a portion of land in return for the building permission for the remaining part of each property to be developed. The Master Plan also aimed at providing social housing because the economic crisis has amplified the gap between housing market prices and household income. This study proposes an equalization and compensation model to support the urban negotiation for providing the indexes of a fair and convenient development of several inter…
Voluntary agreements in protecting privately owned forests in Finland — To buy or to lease?
2008
Abstract A voluntary conservation approach may reveal environmentally minded landowners who are willing to protect their lands with a compensation that is lower than the market price based compensation. Consequently, voluntary conservation programs may induce lower costs than traditional obligatory programs, such as a land taking. We compared the costs accrued from land purchasing with those from temporal land leasing. The costs included both direct costs, such as fees of land acquisition and compensation payments in land leasing, and transaction costs. We used a data set from a Finnish pilot program called Trading in Natural Values (TNV). In this new practice landowners and the authority t…
WHY MOST FIRMS CHOOSE LINEAR HEDGING STRATEGIES
2009
I investigate the efficiency of alternative hedging strategies of nonfinancial firms facing hedgeable price risk, unhedgeable quantity risk, and financial contracting costs in low-profit events. The analysis suggests that variance-minimizing hedging strategies are very close in economic terms to optimal, value-maximizing hedging strategies for most firms. Furthermore, the marginal gains from shifting to nonlinear hedging strategies are often small enough to be neglected. These results illuminate some puzzling findings in survey studies of firms’ hedging practices and suggest an alternative view on firms’ selective hedging practices termed “cautious selective hedging.”
Property prices index numbers and derived indices
2014
Purpose – A useful instrument to understand and examine the inner workings of the property trade is devising index numbers of property prices based on historical sequences of market prices. The present work aims at the definition of index numbers of property prices, proposing an innovative methodology compared with what usually recurs in literature. The purpose of this paper is to discuss these issues. Design/methodology/approach – The analysis proposed, based on the mechanisms of formation of stock indices, investigates the analogies between stock and property information, according to the peculiarities of the property trade, leading to a methodology approach, derived from Simple Price In…
Gradings on the algebra of upper triangular matrices and their graded identities
2004
Abstract Let K be an infinite field and let UT n ( K ) denote the algebra of n × n upper triangular matrices over K . We describe all elementary gradings on this algebra. Further we describe the generators of the ideals of graded polynomial identities of UT n ( K ) and we produce linear bases of the corresponding relatively free graded algebras. We prove that one can distinguish the elementary gradings by their graded identities. We describe bases of the graded polynomial identities in several “typical” cases. Although in these cases we consider elementary gradings by cyclic groups, the same methods serve for elementary gradings by any finite group.
Can Fiscal Policy Stimulus Boost Economic Recovery?
2011
We assess the role played by fiscal policy in explaining the dynamics of asset markets. Using a panel of ten industrialized countries, we show that a positive fiscal shock has a negative impact in both stock and housing prices. However, while stock prices immediately adjust to the shock and the effect of fiscal policy is temporary, housing prices gradually and persistently fall. Consequently, the attempts of fiscal policy to mitigate stock price developments (e.g. via taxes on capital gains) may severely de-stabilize housing markets. The empirical findings also point to significant fiscal multiplier effects in the context of severe housing busts, which gives rise to the importance of the im…
