On the asymptotic distribution of a simple unit root test for trending and breaking series

In this paper, we derive the asymptotic distribution of Popp's (2008) innovational outlier unit root test for trending series with a break. The results of Zivot and Andrews (1992) are applied to provide the limiting results of these new test statistics. We tabulate their asymptotic and finite sample critical values, and illustrate the use of the new statistics with an application to the unemployment rate series for 23 OECD countries.     

A simple unit root testing methodology that does not require knowledge regarding the presence of a break

We develop a simple methodology that allows practitioners to test for the presence of a unit root without a priori knowledge regarding the occurrence of a break under the null hypothesis. We use a pre-test that is readily available in the estimated regression used to calculate the unit root statistics, and so our methodology is very easy to implement. The t-statistic corresponding to the impulse dummy variables evaluated at break date estimator is used as a pre-test to ascertain whether a break exists under the null hypothesis. Finite sample simulations show that our methodology yields tests that maintain their size.     

Inequalities involving expectations of selected functions in reliability theory to characterize distributions

Recently, authors have studied inequalities involving expectations of selected functions, viz. failure rate, mean residual life, aging intensity function, and log-odds rate which are defined for left truncated random variables in reliability theory to characterize some well-known distributions. However, there has been growing interest in the study of these functions in reversed time (X ? x, instead of X > x) and their applications. In the present work we consider reversed hazard rate, expected inactivity time, and reversed aging intensity function to deal with right truncated random variables and characterize a few statistical distributions.     

‘Think imperially’: Indian journalists’ goodwill visits to White Australia, 1927 and 1947

ABSTRACT

Academic research on the White Australia Policy has spanned the history of Asian migration and policy-making initiatives in Australia. However, the role of popular transnational media images and stories of the past that inform the socio-cultural understanding of Australia–India cross-cultural relations has been under evaluated. In this paper, using unexplored archival material from popular newspaper reports and columns, I will examine the ‘goodwill visits’ of two Indian journalists, K. K. Lalkaka and Sir R. Srinivasa Sarma, to Australia in 1927 and 1947. By assessing the role of these two journalists, this paper will highlight transnational issues such as migration, ethnicity, race, class and trade between the two countries. Borrowing from Vineet Thakur’s research highlighting the role of first diplomats in the pre-independence era India, this article will contribute to the field of history in Indian diplomatic studies and historiography of Australian–Indian cross-cultural relations.     

Of monsters

Monsters gave birth to modernity: those unnamable figures of horror and fascination shadow civilization as its constitutive and abjected discontent. In Europe, from the late eighteenth century on, the term monstrosity mobilized a set of discursive practices that tied racial and sexual deviancy to an overall apparatus of discipline, and, later in the nineteenth century, to the emergence of biopolitics. This article draws a history of monstrosity through overlapping discourses, tying the contemporary figure of the monster-terrorist to the sexual and racial deviancy of what Michel Foucault termed the ‘Abnormals.’ Beginning with an engagement with Deleuze's and Foucault's notion of ‘biopolitics,’ this article follows the emergence of the monster-terrorist in that subfield of policy studies known as ‘terrorism studies.’ This article argues that specific and implicit conceptions of the civilized psyche, linked to norms of the heterosexual family, ground the figure of the Islamic terrorist in an older colonial discourse of the despotic and licentious Oriental male.     

Prices,Markups, and Trade Reform

This paper examines how prices, markups, and marginal costs respond to trade liberalization. We develop a framework to estimate markups from production data with multi‐product firms. This approach does not require assumptions on the market structure or demand curves faced by firms, nor assumptions on how firms allocate their inputs across products. We exploit quantity and price information to disentangle markups from quantity‐based productivity, and then compute marginal costs by dividing observed prices by the estimated markups. We use India's trade liberalization episode to examine how firms adjust these performance measures. Not surprisingly, we find that trade liberalization lowers factory‐gate prices and that output tariff declines have the expected pro‐competitive effects. However, the price declines are small relative to the declines in marginal costs, which fall predominantly because of the input tariff liberalization. The reason for this incomplete cost pass‐through to prices is that firms offset their reductions in marginal costs by raising markups. Our results demonstrate substantial heterogeneity and variability in markups across firms and time and suggest that producers benefited relative to consumers, at least immediately after the reforms.     

The Subjective Well-Being of Immigrants: Pre- and Post-migration

In recent years, migration studies have increasingly shown that subjective well-being carries considerable weight in immigrant integration. Yet little is known about the subjective well-being of immigrants in their origin country (pre-migration) or its relation to their well-being in the host country. This paper examines the relationship between subjective well-being, both pre- and post-immigration, among North Americans who arrived in Israel during the past two decades. The study combines both quantitative and qualitative research methods. According to our quantitative findings, the labor market performance of North American immigrants in Israel is lower than in their origin countries. Further, we learned from the qualitative analysis that although the immigrants’ positions in the labor market were better in their origin countries, the immigrants perceived their standard of living in Israel to be the same as in their origin country—if not better—due to the low cost of services in Israel. The importance of the immigrant’s satisfaction from the current job in Israel was apparent in the findings of both methods. We also found that the subjective well-being of North American immigrants in Israel is relatively high, and most immigrants did not consider leaving Israel. The subjective well-being of the immigrants in Israel was found to be related to their social networks in their origin country, to their religious immigration motive and to their work satisfaction in Israel. The more supportive the immigrants’ families were of their decision to immigrate, the less the immigrants tended to consider leaving Israel. Immigrants with a religious motivation for immigrating to Israel were less inclined to leave, and the same was true for immigrants who were satisfied with their work in Israel. The qualitative data added important perspective on the immigrants’ social networks, this time in Israel. Interviewees reported having more supportive social networks in Israel, and a greater sense of community, although most of their contacts were within the Anglo community.     

A Fairly Accurate Approximation to the Area Under Normal Curve

In this article, we present a new approximation to the cumulative distribution function of standard normal distribution. The approximation is fairly accurate with minimum accuracy of seven decimal digits. To the best of our knowledge, this formula outperforms other such approximations available in literature.
