Market frictions inhibit the perfect replication of property derivatives, and define the property spread as a price measure in the incomplete real estate market. We identify transaction costs, transaction time, and short sale constraints as the main frictions in this market. Based on these frictions, we set up a framework of arbitrage free price bounds for property derivatives. In turn, we use observed derivative prices to determine the implied cost of the frictions. Lastly, we verify these values by using other research, which confirms the accuracy of our framework.  相似文献

Fads models were introduced by Shiller (Am Econ Rev 71:421–436, 1981) and Summers (J Finance 41:591–601, 1986) as plausible alternatives to the efficient markets/constant expected returns assumptions. Under these models, logarithms of asset prices embody both a martingale component, with permanent shocks, and a stationary component, with temporary shocks. We study a continuous-time version of these models both from the point of view of informed agents, who observe both fundamental and market values, and from that of uninformed agents, who only observe market prices. We specify the asset price in the larger filtration of the informed agent, and then derive its decomposition in the smaller filtration of the uninformed agent using the Hitsuda representation of Gaussian processes. For uninformed agents we obtain a non-Markovian dynamics, which justifies the use of technical analysis in optimal trading strategies. For both types of agents, we solve the problem of maximization of expected logarithmic utility from terminal wealth, and obtain an explicit formula for the additional logarithmic utility of informed agents. Finally, we apply the decomposition result to the problem of testing the presence of fads from market data. An application to the NYSE-AMEX indices from the CRSP database shows that, if the fads component prevails, then the mean-reversion speed must be slow.  相似文献

Sustainability Northwest (SNW) is a fictional not‐for‐profit organization (NPO) that seeks to develop thought leaders for a sustainable future. This instructional case allows professors to assign students with up to six different roles, including SNW's chair of the board, executive director, volunteer treasurer, and the external auditor. Unique learning objectives include (i) the application of the CPA Canada Handbook, Accounting—Part III to prepare an NPO's financial statements using fund accounting, (ii) the development of recommendations to improve an NPO's board of directors, (iii) the analysis of system flow documents to identify control weaknesses, and (iv) the preparation of an audit planning memo. Instructors can use this case in several milieus. First, professors can foster a student's ability to integrate technical knowledge by (i) assigning students all six roles in a capstone course to promote integration within an individual course or (ii) assigning multiple roles across multiple courses to promote integration across a program of studies. Second, instructors can focus on a particular technical skill by assigning specific roles. This case is ideal for senior‐level undergraduate students or graduate students.  相似文献

The creation of agencies has been and still is a widespread trend in the public sector: governments in many countries often establish semi‐autonomous single‐purpose organizations to carry out a wide range of functions and tasks. The trend to autonomization is problematic as it affects public sector's governance: several bodies operate partly autonomously from the core elective government, and are sometimes loosely coupled with their ‘parent’ administration. Consequently, analysing the drivers of agencies’ autonomy is a crucial issue for public management. This paper, in the light of some major contributions in organizational science, assumes that agencies’ autonomy is influenced by factors that affect post‐delegation relationships: agencies’ structure, culture and nature of the tasks executed. The study was aimed at testing a range of hypotheses about the autonomy of public agencies, using for this purpose the so‐far not investigated case of Italy–much in the spirit of the accumulation of knowledge in an area of public management. Results do not provide any strikingly counter‐intuitive finding, but a mix of confirmations and disconfirmations of previous findings that allow a finer‐grained analysis on the determinants of agency autonomy.  相似文献

We compare price dynamics of different market protocols (batch auction, continuous double auction and dealership) in an agent-based artificial exchange. In order to distinguish the effects of market architectures alone, we use a controlled environment where allocative and informational issues are neglected and agents do not optimize or learn. Hence, we rule out the possibility that the behavior of traders drives the price dynamics. Aiming to compare price stability and execution quality in broad sense, we analyze standard deviation, excess kurtosis, tail exponent of returns, volume, perceived gain by traders and bid-ask spread. Overall, a dealership market appears to be the best candidate, generating low volume and volatility, virtually no excess kurtosis and high perceived gain.  相似文献

In their very interesting paper “Set-packing problems and threshold graphs” [1] V. Chvatal and P. L. Hammer have shown that the constraints $$begin{gathered} sumlimits_{j = 1}^n {a_{ij} x_j leqslant 1(i = 1,2, . . . , m)} hfill x_j in (0,1)(j = 1,2, . . . , n) hfill end{gathered} $$ are equivalent to the only inequality $$begin{gathered} sumlimits_{j - 1}^n {c_j x_j leqslant d} hfill x_j in (0,1)(j = 1,2, . . . , n) hfill end{gathered} $$ if and only if the intersection graph associated with the matrix (a ij ) — see § 1 — is a threshold graph i.e. a graph none of whose induced subgraphs are isomorphic to 2K 2,P 4,C 4: As Chvatal and Hammer have shown [1], threshold graphs can be characterised in many different ways; the main result of this paper is to give a new, very simple characterisation which will enable us to test whether a graph is a threshold by a simple inspection of its incidence matrix.  相似文献

This paper investigates the relationship between financial institutions' expectations of the current account and the fiscal balance. Using professional macroeconomic forecasts for the G‐7 countries, we find a positive relationship between forecasts of the cyclically adjusted fiscal balance deficit and forecasts of the current account deficit, indicating that professional forecasts embody links implied by the twin deficits hypothesis. In assessing the relationship between the forecasts of the fiscal deficit and the current account, we find that forecasters correctly make the distinction between the effect of fiscal policy and automatic stabilizers.  相似文献

The relationship between international trade and foreign direct investment (FDI) is one of the main features of globalisation. In this paper, we investigate the effects of FDI on trade from a network perspective, since FDI takes not only direct but also indirect channels from origin to destination countries because of firms’ incentive to reduce tax burden, to minimise coordination costs and to break barriers to market entry. We use a unique data set of international corporate control as a measure of stock FDI to construct a corporate control network (CCN), where the nodes are the countries and the edges are the corporate control relationships. Network measures, as the shortest path length and the communicability, are then computed on the CCN to capture the indirect channel of FDI. Empirically, we find that corporate control has a positive effect on trade both directly and indirectly. The result is robust with different specifications and estimation strategies. Hence, our paper provides strong empirical evidence of the indirect effects of FDI on trade. Moreover, we identify a number of interplaying factors such as regional trade agreements and the region of Asia. We also find that the indirect effects are more pronounced for the manufacturing sector than for primary sectors such as oil extraction and agriculture.  相似文献

We argue that embedding endowment-based comparative advantage within a standard NEG framework helps solve the indeterminacy due to multiple equilibria and the ambiguity concerning the relation between integration and specialisation (monotonicity versus non-monotonicity) typical of the NEG literature. In particular, we show that if endowments are in the FPE set, the process of trade integration involves an overshooting of international specialisation and relative factor prices with respect to the free trade level determined by factor abundance. In contrast, if endowments are outside the FPE set, then, even in the presence of agglomeration forces, specialisation and factor prices are monotonically related to trade costs, as implied by the standard trade theory. We argue that the model can shed light on some puzzling stylised facts.  相似文献

This paper analyses the economic impact of digital technologies in Europe distinguishing between different stages/domains of the digitalization process. A set of composite Information and Communication Technologies (ICT) indicators is used for capturing the access to ICTs, the ability to use them and the digital empowerment of individuals in key social and economic domains. We argue that the mere accessibility to ICT facilities is only a pre-condition for moving towards a digitalized society, while the ‘level’ and the ‘quality’ in the use of these technologies, as well as the conditions facilitating or hampering digital empowerment, play a much more important role. Several transmission mechanisms from ICT access, usage and digital empowerment to key macro-economic variables (namely labour productivity, gross domestic product per capita, employment growth and the employment rate) are identified. The econometric evidence supports our hypotheses showing that the usage of ICT, and mostly digital empowerment, exert the major economic effects, especially on employment also favouring the inclusion of ‘disadvantaged’ groups in the labour market. We conclude that digitalization may drive productivity and employment growth and that inclusive policies may effectively contribute to bridge the gap between the most favoured and the disadvantaged parts of the population, thus helping in achieving the 2020 Europe targets.  相似文献
