ABSTRACTThe European sovereign debt crisis has increased the uncertainty regarding the benefits and costs of membership in the Economic and Monetary Union. In this article, we decided not to propose a general model but to focus on one of the important components of the European financial integration. In particular, we develop a structural gravity model, influenced by some very recent theoretical and econometric advancements. This new structural gravity approach provides needed theoretical underpinnings as well as strong support for the econometric estimation of gravity models. 相似文献

Endogenous economic freedom and the wealth of nations: evidence from a panel of countries, 1996–2011
Indexes of economic freedom measure the degree to which the policies and institutions of countries are supportive of economic freedom. The authors find a considerable scope for improvement in Index of Economic Freedom, created by Heritage Foundation, since not all components of index have equal effect on economic well-being. Contrary to Heritage methodology the authors tackle the aggregation bias and highlight that each index component contributes differently to the level of economic freedom and subsequently to the level of income per capita. The level of fiscal freedom and monetary freedom exert the strongest influence on the overall index of economic freedom. Authors present the new endogenous cross-country ranking of 135 countries from Instrumental Variable-Two Stage Least Squares (IV-2SLS) empirical specification which removes the inconsistencies arising from the arbitrary assumption of the equivalent effect of each component on the overall index and, hence, the level of real income per capita. 相似文献

We analyze the behavior of the implied volatility smile for options close to expiry in the exponential Lévy class of asset price models with jumps. We introduce a new renormalization of the strike variable with the property that the implied volatility converges to a nonconstant limiting shape, which is a function of both the diffusion component of the process and the jump activity (Blumenthal–Getoor) index of the jump component. Our limiting implied volatility formula relates the jump activity of the underlying asset price process to the short‐end of the implied volatility surface and sheds new light on the difference between finite and infinite variation jumps from the viewpoint of option prices: in the latter, the wings of the limiting smile are determined by the jump activity indices of the positive and negative jumps, whereas in the former, the wings have a constant model‐independent slope. This result gives a theoretical justification for the preference of the infinite variation Lévy models over the finite variation ones in the calibration based on short‐maturity option prices. 相似文献

ABSTRACTThis paper examines whether a long-run relationship exists between CO2 emissions and selected variables: real gross domestic product per capita, inward stock of foreign direct investments, gross fixed capital formation, industry, value added and energy use per capita for Colombia, Indonesia, Viet Nam, Egypt, Turkey and South Africa countries in the period of 1989–2016. We used panel unit root testing, followed by panel cointegration tests and panel causality. The results clearly prove the existence of a bidirectional long-run causal relationship between all the variables except between CO2 emissions and GDP and CO2 emissions and GFCF. Major finding of the short-run causality analysis is that CO2 emission in the short run does not result in changes of other variables. On the other hand, all variables except foreign direct investments (FDI) cause the changes in the CO2 emissions, and there is a positive bidirectional causal relationship between GDP and FDI, between GFCF and FDI, and between GFCF and IVA. Finally, positive unidirectional causal relationship also exists, running from GDP to IVA, GDP to ENUSE, IVA to FDI and ENUSE to FDI. 相似文献

Sequential vs. single-round uniform-price auctions 总被引:1,自引:0,他引:1
We study sequential and single-round uniform-price auctions with affiliated values. We derive symmetric equilibrium for the auction in which k1 objects are sold in the first round and k2 in the second round, with and without revelation of the first-round winning bids. We demonstrate that auctioning objects in sequence generates a lowballing effect that reduces the first-round price. Total revenue is greater in a single-round, uniform auction for k=k1+k2 objects than in a sequential uniform auction with no bid announcement. When the first-round winning bids are announced, we also identify a positive informational effect on the second-round price. Total expected revenue in a sequential uniform auction with winning-bids announcement may be greater or smaller than in a single-round uniform auction, depending on the model's parameters. 相似文献

The papers (Forde and Jacquier in Finance Stoch. 15:755?C780, 2011; Forde et al. in Finance Stoch. 15:781?C784, 2011) study large-time behaviour of the price process in the Heston model. This note corrects typos in Forde and Jacquier (Finance Stoch. 15:755?C780, 2011), Forde et al. (Finance Stoch. 15:781?C784, 2011) and clarifies the proof of Forde et al. (Finance Stoch. 15:781?C784, 2011, Proposition 2.3). 相似文献

ABSTRACTThe purpose of the study is to investigate the moderating effects of gender on proposed model relationships. In order to test the moderating effects of gender on the relationships of the model developed, multi-group SEM was applied. Performance expectancy was found to be the strongest predictor of satisfaction and comparative value was identified as the main driver of continuance intention. In addition, significant difference in attitudes between women and men were confirmed in the case of three out of ten effects. The originality of the study is its measurement of the moderating effects of gender on user satisfaction in relation to m-commerce and continuance intentions. 相似文献

This note identifies a gap in the proof of Corollary 2.4 in Forde and Jacquier (Finance Stoch., 2011) which arises because the essential smoothness of the family (X
t
/t)
t≥1 can fail for the log-spot process X in the Heston model, and it describes how to circumvent the issue by applying a standard argument from large deviation theory. 相似文献
