Testing, monitoring, and dating structural changes in exchange rate regimes

Linear regression models for de facto exchange rate regime classification are complemented by inferential techniques for evaluating the stability of the regimes. To simultaneously assess parameter instabilities in the regression coefficients and the error variance an (approximately) normal regression model is adopted and a unified toolbox for testing, monitoring, and dating structural changes is provided for general (quasi-)likelihood-based regression models. Subsequently, the toolbox is employed for investigating the Chinese exchange rate regime after China gave up on a fixed exchange rate to the US dollar in 2005 and for tracking the evolution of the Indian exchange rate regime from 1993 until 2008.

Export Versus FDI in Services

In the literature on exports and investment, most productive firms are seen to invest abroad. In the Helpman et al. (2004) model, costs of transportation play a critical role in the decision about whether to serve foreign customers by exporting, or by producing abroad. We consider the case of tradable services, where the marginal cost of transport is near zero. We argue that in the purchase of services, buyers face uncertainty about product quality, especially when production is located far away. Firm optimisation then leads less productive firms to self-select themselves for FDI. We test this prediction with data from the Indian software industry, and find support for it.

Graduating to Globalisation: a study of Southern multinationals

FDI by firms in developing countries is a recent phenomenon and demands a study of relationship between firm productivity and different modes of globalisation activities. This paper attempts to understand this relationship through ordered probit models, examining two key hypotheses using firm level panel data from India. First, we test whether there are characteristic differences between domestic firms, exporting firms and firms engaging with FDI. Second, we test if FDI is an integral part of the evolution of firms in developing countries. Our results suggest that there are strong differences between domestic firms, exporting firms, and firms that invest abroad, especially in their knowledge investment, indicating the presence of a ladder of quality in graduating to globalisation.

Managing Capital Flows: The Case of India

From the early 1990s, India embarked on easing capital controls. Liberalization emphasised openness towards equity flows, both FDI and portfolio flows. In particular, there are few barriers in the face of portfolio equity flows. In recent years, a massive increase in the value of foreign ownership of Indian equities has come about, largely reflecting improvements in the size, liquidity and corporate governance of Indian firms. While the system of capital controls appears formidable, the de facto openness on the ground is greater than is apparent, particularly because of the substantial enlargement of the current account. These changes to capital account openness were not accompanied by commensurate monetary policy reform. The monetary policy regime has consisted essentially of a pegged exchange rate to the US dollar throughout. Increasing openness on the capital account, coupled with exchange rate pegging, has led to a substantial loss of monetary policy autonomy. The logical way forward now consists of bringing the de jure capital controls uptodate with the de facto convertibility, and embarking on reforms of the monetary policy framework so as to shift the focus of monetary policy away from the exchange rate to domestic inflation.

Emerging Economy Business Cycles : Financial Integration and Terms of Trade Shocks

This paper analyses the extent to which financial integration impacts the manner in which terms of trade affct business cycles in emerging economies. Using a small open economy model, we show that as capital account openness increases in an economy that faces trade shocks, business cycle volatility reduces. For an economy with limited financial openness, and a relatively open trade account, a model with exogenous terms of trade shocks is able to replicate the features of the business cycle.

Dating business cycles in India

This paper presents a chronology of Indian business cycle in the post-reform period. The period before reforms primarily saw monsoon cycles. We find three episodes of recession in the post-reform period: 1999Q4 to 2003Q1, 2007Q2 to 2009Q3, and 2011Q2 to 2012Q4. We find that the average duration of expansion is 12 quarters and the average duration of recession is 9 quarters. The diversity in duration of expansion is seen to be 0.34 while the diversity in duration of recession is 0.31. We find that the amplitude of recession is relatively more diverse at 0.45 while the diversity in amplitude of expansion is 0.38.

Business Cycle Measurement in India

This paper presents the business cycle chronology for the Indian economy. Two distinct phases are analysed. The pre-1991 period when the cycles were mainly driven by monsoon shocks. The post 1991 phase where we see the emergence of conventional business cycles driven by investment-inventory fluctuations. The paper sheds light on the economic conditions that shaped the nature of cycles in the two phases. The concluding section of the paper presents an overview of the economic conditions post 2012.

A cross-country Exchange Market Pressure (EMP) dataset

The data presented in this article are related to the research article titled - “An exchange market pressure measure for cross country analysis” (Patnaik et al. [1]). In this article, we present the dataset for Exchange Market Pressure values (EMP) for 139 countries along with their conversion factors, ρ (rho). Exchange Market Pressure, expressed in percentage change in exchange rate, measures the change in exchange rate that would have taken place had the central bank not intervened. The conversion factor ρ can interpreted as the change in exchange rate associated with

Foreign shareholding: a decomposition analysis

1 billion of intervention. Estimates of conversion factor ρ allow us to calculate a monthly time series of EMP for 139 countries. Additionally, the dataset contains the 68% confidence interval (high and low values) for the point estimates of ρ’s. Using the standard errors of estimates of ρ’s, we obtain one sigma intervals around mean estimates of EMP values. These values are also reported in the dataset.

The Exchange Rate Regime in Asia: From Crisis to Crisis

Stulz (2005) has emphasized that for home bias to decline, insiders have to reduce ownership so as to make purchase of shares by foreigners possible. We offer a decomposition in the ownership of shares by foreigners into three parts: the change in insider shareholding, the change in market capitalization and the change in the fraction of outside shareholding that is held by foreigners. As an example, this decomposition is applied to help understand the sharp change in foreign ownership of Indian firms after 2001.
