Posted: 06 Sep 2015 05:36 PM PDT

In this paper, the valuation of European and path-dependent options in FX markets is considered when the currency exchange rate evolves according to the Heston model combined with the Cox-Ingersoll-Ross dynamics for the stochastic domestic and foreign interest rates. The mixed Monte Carlo/PDE method requires that we simulate only the paths of the squared volatility and the two interest rates,...

Published / Preprint: Measuring economic complexity of countries and products: which metric to use?. (arXiv:1509.01482v1 [q-fin.EC])

Posted: 06 Sep 2015 05:36 PM PDT

Evaluating the economies of countries and their relations with products in the global market is a central problem in economics, with far-reaching implications to our theoretical understanding of the international trade as well as to practical applications, such as policy making and financial investment planning. The recent Economic Complexity approach aims to quantify the competitiveness of...

Published / Preprint: On the emergence of scale-free production networks. (arXiv:1509.01483v1 [q-fin.GN])

Posted: 06 Sep 2015 05:36 PM PDT

Building upon the standard model of monopolistic competition on the market for intermediary goods, we propose a simple dynamical model of the formation of production networks. The model subsumes the standard general equilibrium approach and robustly reproduces key stylized facts of firms' demographics. Firms' growth rates are negatively correlated with size and follow a core double-exponential...

Published / Preprint: Risk Overhang and Loan Portfolio Decisions: Small Business Loan Supply Before and During the Financial Crisis

Posted: 04 Sep 2015 02:47 AM PDT

We estimate a structural model of bank portfolio lending and find that the typical U.S. community bank reduced its business lending during the global financial crisis. The decline in business credit was driven by increased risk overhang effects (consistent with a reduction in the liquidity of assets held on bank balance sheets) and by reduced loan supply elasticities suggestive of credit...

Published / Preprint: Is Historical Cost Accounting a Panacea? Market Stress, Incentive Distortions, and Gains Trading

Posted: 04 Sep 2015 02:46 AM PDT

Accounting rules, through their interactions with capital regulations, affect financial institutions̢۪ trading behavior. The insurance industry provides a laboratory to explore these interactions: life insurers have greater flexibility than property and casualty insurers to hold speculative-grade assets at historical cost, and the degree to which life insurers recognize market values differs...

Published / Preprint: The scaling of income inequality in cities. (arXiv:1509.00959v1 [physics.soc-ph])

Posted: 03 Sep 2015 05:37 PM PDT

Developing a scientific understanding of cities in a fast urbanizing world is essential for planning sustainable urban systems. Recently, it was shown that income and wealth creation follow increasing returns, scaling superlinearly with city size. We study scaling of per capita incomes for separate census defined income categories against population size for the whole of Australia. Across several...

Published / Preprint: Sequential Design for Ranking Response Surfaces. (arXiv:1509.00980v1 [stat.ML])

Posted: 03 Sep 2015 05:37 PM PDT

We propose and analyze sequential design methods for the problem of ranking several response surfaces. Namely, given $L \ge 2$ response surfaces over a continuous input space $\cal X$, the aim is to efficiently find the index of the minimal response across the entire $\cal X$. The response surfaces are not known and have to be noisily sampled one-at-a-time. This setting is...

Published / Preprint: An Insurance-Led Response to Climate Change. (arXiv:1509.01157v1 [physics.soc-ph])

Posted: 03 Sep 2015 05:37 PM PDT

Climate change is widely expected to increase weather related damage and the insurance claims that result from it. This has the undesirable consequence of increasing insurance costs, in a way that is independent of a customer's contribution to the causes of climate change. This is unfortunate because insurance provides a financial mechanism that mitigates some of the consequences of climate...

Posted: 03 Sep 2015 05:37 PM PDT

In many countries information on expectations collected through consumer confidence surveys are used in macroeconomic policy formulation. Unfortunately, before doing so, the consistency of responses is often not taken into account, leading to biases creeping in and affecting the reliability of the indices hence created. This paper describes how latent class analysis may be used to check the...

Posted: 03 Sep 2015 05:37 PM PDT

Presented is an analytic microeconomic model of the temporal price dispersion of homogeneous goods in polypoly markets. This new approach is based on the idea that the price dispersion has its origin in the dynamics of the purchase process. The price dispersion is determined by the chance that demanded and supplied product units meet in a given price interval. It can be characterized by a...

Published / Preprint: Tax Bond Creation Using a Structural Model and its Extensions. (arXiv:1509.01218v1 [q-fin.PR])

Posted: 03 Sep 2015 05:37 PM PDT

This article describes and explores taxes and debt in finance. Here a situation is thought about, where tax payments would qualify to be considered as debt. Using this principle we can infer that it is possible to create and price a type of bond (Tax Normalization Guarantee) for companies, which would allow them to enter in temporary tax breaks to allow them to free capital. Finally it is...
