Vector‐borne diseases (VBDs) are widespread in less developed countries and reemerging in developed ones. Available economic studies agree that VBDs have significant effects on countries' economic outcomes, and affirm that a systematic evaluation of such effects is crucial for the efficient allocation of resources to health‐related priorities. This paper provides a comparative assessment of available methodologies for measuring the economic impact of VBDs at national level. We review both macroeconometric and micro‐based approaches, and examine advantages and disadvantages of current methods. We conclude by suggesting possible areas for future research. 相似文献

In this paper, we use firm-level data on the universe of Italian manufacturing multi-product exporters to test whether demand shocks in export markets lead multi-product exporters to increase their productivity. The main mechanism behind the documented productivity gains is the reallocation of resources across products within firms (American Economic Review, 104, 2014 and 495; National Bureau of Economic Research Working Paper Series No. 22433, 2016). Intuitively, the increased demand stemming from foreign markets will induce firms to adjust their product mix by moving inputs from low to high productive/profitable uses. We find that these productivity gains are significant and can explain between 1/10 and 1/2 of aggregate productivity growth in the manufacturing sector. 相似文献

We propose two methods to choose the variables to be used in the estimation of the structural parameters of a singular DSGE model. The first selects the vector of observables that optimizes parameter identification; the second selects the vector that minimizes the informational discrepancy between the singular and non‐singular model. An application to a standard model is discussed and the estimation properties of different setups compared. Practical suggestions for applied researchers are provided.

We investigate the political determinants of liberalization in OECD network industries, performing a panel estimation over
30 years, through the largest and most updated sample available. Our results contrast with the traditional wisdom according
to which right-wing governments do promote market-oriented policies more intensively than left-wing ones. Our findings reveal
a neglected role of the so-called neoliberalism in promoting left-wing market-oriented policy. As a result, we claim that
ideological cleavages ceased to act as determinants of the liberalization wave observed in network industries. This result
is confirmed when controlling for the existing regulatory conditions that executives find when elected. Furthermore, we find
that the country’s exposure to other countries’ policy initiatives acts as a positive stimulus for liberalization policies. 相似文献

In this study we develop a new methodological proposal to incorporate risk into a farm‐level positive mathematical programming (PMP) model. We estimate simultaneously the farm nonlinear cost function and a farmer‐specific coefficient of absolute risk aversion as well as the resource shadow prices. The model is applied to a sample of representative arable crop farms from the Emilia‐Romagna region in Italy. The estimation results confirm the calibration ability of the model and reveal the values of the individual risk aversion coefficients. We use the model to simulate different scenarios of crop price volatility, in order to explore the potential risk management role of an agri‐environmental scheme. 相似文献

The aim of this paper is extensively investigate the performance of the estimators for the Greeks of multidimensional complex path-dependent options obtained by the aid of Malliavin Calculus. The study analyses both the computation effort and the variance reduction in the Quasi-Monte Carlo simulation framework. For this purpose, we adopt the approach employed by Montero and Kohatsu-Higa to the multidimensional case. The multidimensional setting shows the convenience of the Malliavin Calculus approach over different techniques that have been previously proposed. Indeed, these techniques may be computationally expensive and do not provide enough flexibility for variance reduction. In contrast, the Malliavin approach provides a class of functions that return the same expected value (the Greek) with different accuracies. This versatility for variance reduction is not possible without the use of the generalized integral by part formula of Malliavin Calculus. In the multidimensional context, we find convenient formulas that permit to improve the localization technique, introduced in Fournié et al. and reduce both the computational cost and the variance. Moreover, we show that the parameters for the variance reduction can be obtained on the flight in the simulation. We illustrate the efficiency of the proposed procedures, coupled with the enhanced version of Quasi-Monte Carlo simulations as discussed in Sabino, for the numerical estimation of the Deltas of call, digital Asian-style and exotic basket options with a fixed and a floating strike price in a multidimensional Black-Scholes market. Given the fact that the gammas of a call option coincides, apart from a constant, with the deltas of digital options, this setting also covers the analysis of formulas tailored for the second order Greeks of call options. 相似文献

The three exchange rate regimes adopted by Italy from 1883 up to the eve of World War I — the gold standard (1883–1893), floating
rates (1894–1902), and “gold shadowing” (1903–1911)—produced a puzzling result: formal adherence to the gold standard ended
in failure while shadowing the gold standard proved very successful. This paper discusses the main policies underlying Italy’s
performance particularly focusing on the strategy of reserve accumulation. It presents a cointegration analysis identifying
a distinct co-movement between exchange rate, reserves, and banknotes that holds over the three sub-periods of the sample.
Given this long-run relationship, the different performance in each regime is explained by the diversity of policy measures,
reflected in the different variables adjusting the system in the various regimes. Italy’s variegated experience during the
gold standard provides a valuable lesson about current developments in the international scenario, showing the central role
of fundamentals and consistent policies. 相似文献
