This paper develops new methods for determining the cointegration rank in a nonstationary fractionally integrated system, extending univariate optimal methods for testing the degree of integration. We propose a simple Wald test based on the singular value decomposition of the unrestricted estimate of the long run multiplier matrix. When the “strength” of the cointegrating relationship is less than 1/2, the test statistic has a standard asymptotic distribution, like Lagrange Multiplier tests exploiting local properties. We consider the behavior of our test under estimation of short run parameters and local alternatives. We compare our procedure with other cointegration tests based on different principles and find that the new method has better properties in a range of situations by using information on the alternative obtained through a preliminary estimate of the cointegration strength. 相似文献

This paper examines an industry‐level model developed to analyze the impact of affiliates of multinational firms (MNFs) on the host country's revealed comparative advantages (RCAs), which predicts that the referred impact is given by both technology service and industry orientation. Based on Brazilian manufacturing industries during the import‐substitution industrialization, panel data estimates show that MNFs negatively affected RCA, which is explained by location advantages in industries presenting comparative disadvantages, as reinforced by a location model. Two other important results are: (i) import protection had a stronger anti‐export effect on multinationals than on national firms; (ii) MNFs were concentrated in industries with lower world‐export growth. 相似文献

This paper addresses the question of what it takes to obtain a well-defined extensive form game. Without relying on simplifying finiteness or discreteness assumptions, we characterize the class of game trees for which all pure strategy combinations induce unique outcomes. The generality of the set-up covers “exotic” cases, like stochastic games or decision problems in continuous time (differential games). We find that the latter class, though a well-defined problem, fails this test. 相似文献

There is currently much debate in the economic literature about whether ethical investment involves a financial sacrifice
or premium. One of the most common methods of testing this compares the financial performance of ethical investment funds
with that of other funds not considered “socially responsible” or ethical. The majority of these research studies evaluate
the performance of the ethical funds according to classic measures, whereby different financial markets, in different countries
and for different periods of time serve as reference for evaluation. The ultimate conclusion of all of these studies is that
there are no significant differences between the performance results of one type of funds and the other. In Spain, ethical
investment funds are still an incipient sector of investment. To date, the Spanish market has not been included in any type
of analysis of these characteristics. Therefore the main objective of this article is to compare the financial performance
of ethical investment funds to that of other funds in the Spanish retail market. We propose the aggregate type of analysis
as the Spanish ethical investment funds have experienced a weaker development in comparison to those of other developed countries.
In the first step we suggest the financial performance to be compared by style analysis since the asset distribution of the
Spanish Social Return Investment (SRI) funds differs from the European trend. In particular, we use the multifactor regression
model with style benchmarks. We found that their financial performance is in all cases superior or similar to that achieved
by the rest of the funds. In the second step, to achieve a more robust and homogeneous comparison, we used the bootstrap method,
comparing ethical and non-ethical fund subsamples by homogeneous groups. No significant differences between these two types
of funds have been found. Thus, if we assume the positive o neutral effect of ethical investment on investor utility in the
retail Spanish market the financial and social performance (FSP) of ethical funds will be, in aggregate, superior to the FSP
achieved by conventional funds. In conclusion, the financial performance of ethical mutual funds in Spain is no sacrifice. 相似文献

This paper is devoted to the analysis of the estimation of the mean of a sensitive variable. The use of a randomized response
(RR) procedure gives confidence to the interviewed that his privacy is protected. We consider that a simple random sampling
with replacement design is used for selecting a sample. The behavior of the RR procedure, when ranked set sampling is the
design used, is developed under three different ranking criteria. The usual gain in accuracy associated with the use of ranked
set sampling is exhibited only by one of the designs. The behavior of the models is illustrated using data provided by a study
of samples of persons infected with AIDS. 相似文献

One similarity among many developed economies is the predominance of cash over electronic payments in terms of payment frequency, especially for the low‐value transactions that are the bulk of retail payments. We use the Bank of Canada's 2009 Methods‐of‐Payment Survey, which collected information on consumers' payment choices through shopping diaries, to estimate a simple model of choice between cash and other payment methods. Results suggest that the main reasons cash is still a popular payment instrument in Canada, especially for low‐value transactions, are its wide acceptance among merchants compared with other alternatives, speed and ease of use, and low marginal cost when on hand.

Mozambique Metical Exchange Rate Dynamics: Evidence of Fractional Co‐Integration in the USA and South African Rates 下载免费PDF全文

This paper studies the exchange rate dynamics of the Mozambique metical with respect to the US dollar and the South African rand. However, instead of using standard I(0)/I(1) techniques, we use long memory and fractionally integrated and co‐integrated models. Our results indicate that the two exchange rates are highly persistent, with orders of integration equal to or above 1. They also seem to be co‐integrated, with an order of integration close to albeit above 0 but with an AR coefficient very close to 1. Thus, although the two series seem to be fractionally co‐integrated, shocks in the long‐run relationship between the two variables are persistent and take a long time to disappear. 相似文献

Does Energy Consumption Respond to Price Shocks? Evidence from a Regression‐Discontinuity Design 下载免费PDF全文
Paulo Bastos Lucio Castro Julian Cristia Carlos Scartascini 《The Journal of industrial economics》2015,63(2):249-278
We exploit unique features of a recently introduced tariff schedule for natural gas in Buenos Aires to estimate the short‐run impact of price shocks on residential energy utilization. The schedule induces a non‐linear and non‐monotonic relationship between households' accumulated consumption and unit prices, thus generating exogenous price variation, which we exploit in a regression‐discontinuity design. We find that a price increase causes a prompt and significant decline in gas consumption. The results also indicate that consumers respond more to recent past bills than to expected prices, which argues against an assumption of perfect awareness of complex price schedules by consumers. 相似文献

The appropriation of water for economic activities is limited by regional surface and underground endowments, and symptoms of environmentally unsustainable withdrawals are already visible in many regions of the world. In this paper we investigate the economic implications of water policy imposing source- and region-specific restrictions on water withdrawals taking the Mexican economy as a case study. We use an inter-regional input–output model of Mexico's hydro-economic regions to allocate production subject to the availability of water and other factors of production. Water sustainability requires a reduction of 7.5?km3/yr of groundwater withdrawals, which is compensated by an increase of 3.4?km3/yr of surface water, an expansion onto an additional 1.4 million hectares of rainfed land, and modifications in subnational patterns of food trade. This framework for evaluating scenarios describing sustainability-oriented water policies is readily applicable to other regions. 相似文献

We analyse why the Chinese government sets restrictions on foreign direct investment (FDI). We focus our analysis on the percentage of shares in relocated firms that the government allows to be foreign‐owned. The government's decision on this percentage depends on the entry cost, the number of firms that relocate and the weight of the consumer surplus in the objective function of the government. We show that by its choice of this percentage, the Chinese government may restrict or encourage FDI to its country. We also find that if the government may subsidise the fixed entry cost, it provides a subsidy only when the producer surplus has a greater weight than the consumer surplus in weighted welfare. In that case, the subsidy encourages relocation by both firms and permits the government to allow a lower percentage of shares to be foreign‐owned in relocated firms. 相似文献
