Asset price dynamics in a “bull and bear market”
2021
Abstract We generalize an existing asset market model with heterogenous agents. In particular, we consider the case in which no-trade and low-trade intervals of chartists and fundamentalists respectively are not congruent. Thus we model chartist and fundamentalists who respond to asset prices in agent-specific neighborhoods around the fundamental value with different trade intensities. The resulting asset price dynamics is generated by a one-dimensional 5-piece linear map with discontinuities. Our analysis of this map focusses on coexisting price equilibria. Conditions for their existence and stability are determined analytically. By visualizing the results we allow for a basic bifurcation …
Bank fragility and contagion: Evidence from the bank CDS market
2016
Understanding how contagion works among financial institutions is a top priority for regulators and policy makers who aim to foster financial stability and to prevent financial crises. Using bank credit default swap (CDS) data, we provide a framework for the evaluation of contagion among banks in different countries and regions during a period of prolonged financial distress. We measure contagion in terms of return spillovers, following a Generalized VAR (GVAR) approach. In addition, we propose an innovative framework to distinguish between two types of contagion: systematic (linked to global factors), and idiosyncratic (linked to bank specific factors). We find evidence of both types of co…
Investment–productivity dynamics and distribution dynamics in a multisector economy: some theory and an application to Italian regions
2003
Abstract In this paper, we study the investment–productivity dynamics in the Framework Space, presented by Bohm and Punzo [Cycles, Growth and Structural Change, Routledge, London (2001) 47], as the distribution dynamics of the production sectors of an economy. We apply such theoretical framework to data from Italian regions to identify differences in sectoral behaviors both within and across regions. Our main findings are: sectors within a region generally follow different regime dynamics; Southern Italian regions are generally characterized by higher degrees of heterogeneity in sectoral growth behaviors and of regime instability. Also, we find support to the hypothesis of a positive relati…
Spillovers through banking centers: a panel data analysis of bank flows
2003
Abstract This paper presents evidence that spillovers through bank lending contributed to the transmission of currency crises during the recent episodes of financial instability in emerging markets. The innovation of the paper is that it looks beyond aggregated measures of contagion into the structure of bank flows, disaggregating by banking centers. The main findings are that spillovers caused by banks’ exposures to a crisis country help predict flows in third countries after the Mexican and Asian crises, but not after the Russian crisis. In the latter, there is evidence of a generalized outflow from emerging markets. The importance of spillovers through banking centers suggests that count…
The Role of Capital and Liquidity in Bank Lending: Are Banks Safer?
2020
The aim of this paper is to examine whether and to what extent bank capital requirements and liquidity standards influence the level of bank stability. Our approach is that both capital and liquidity affect lending growth, which in turn affects bank stability. We construct a panel dataset on a sample of 2,054 commercial banks from 117 developed and developing countries during the 2000–16 period. By applying a two-stage least squares (2SLS) empirical methodology, our findings show that capital and liquidity have a negative direct impact on the level of bank stability. However, this influence is counteracted by an indirect positive effect through the increased level of credit. Our results are…
TESTING FOR CONTAGION: A CONDITIONAL CORRELATION ANALYSIS
2005
Abstract In this paper, we test for contagion within the East Asian region, contagion being defined as a significant increase in the degree of comovement between stock returns in different countries. For this purpose, we use a parameter stability test, and, following [Rigobon, R., 2003a. On the measurement of the international propagation of shocks: is the transmission stable?, Journal of International Economics], we control for three types of bias, resulting from heteroscedasticity, endogeneity and omitted variable, respectively. The null of interdependence against the alternative of contagion is then tested as an overidentifying restriction. Unlike other studies, our approach is based on …
Structural Change in Finnish Manufacturing: The Theory of the Aggregation of Production Functions and an Empirical Analysis with a Plant-Level Panel
2011
Abstract In this paper, structural change in the Finnish manufacturing industries is studied using the theory of the aggregation of production functions and longitudinal plant-level data for the period from 1980 to 2005. To characterise the nature of structural change in 12 industries, we examine the invariance of aggregate production functions over time. Aggregate production functions need not be estimated because, according to the theory of the aggregation of production functions, the invariance can be analysed by investigating the stability of capacity density functions, which describe the distribution of value added in these industries. Even though the shapes of aggregate production fun…
Instability tests in cointegration relationships. An application to the term structure of interest rates
2002
Abstract This paper tries to review, from a practitioner's point of view, the recent strand of literature on cointegration tests allowing for structural changes or parameter instability. Thus, we apply several tests using as an example the expectations model of the term structure of interest rates. The results are consistent with the existence of cointegration between the long and the short run Spanish interest rates, with a vector (1,−1), as predicted by the theory. However, there is also evidence of structural instability, mainly at the beginning of 1994, that can be attributed to the financial changes that occurred in Spain as a result of its external commitments in the process of the Eu…
Can stability of foreign aid agreement reduce global income inequality?
2017
Abstract Global initiatives on debt relief call for increasing foreign aid assistance to alleviate income inequality. But the potential gains from foreign aid policy coordination may be limited by the willing participation of diverse and self-interested donor countries. If stability of the foreign aid agreement does not occur, then aid effectiveness fails. Thus, the aim of this paper is to investigate the effects of the stability of foreign aid agreement on income redistribution amongst countries. The findings show that stability has positive effects on income mobility from the rich to the poorest countries reducing global income inequality.
On the stability of stablecoins
2021
This paper investigates the volatility processes of stablecoins and their potential stochastic interdependencies with Bitcoin volatility. We employ a novel approach to choose the optimal combination for the power law exponent and the minimum value for the volatilities bending the power law. Our results indicate that Bitcoin volatility is well-behaved in a statistical sense with a finite theoretical variance. Surprisingly, the volatilities of stablecoins are statistically unstable and contemporaneously respond to Bitcoin volatility. Also, whereas the volatilities of stablecoins are not Granger-causal for Bitcoin volatility, lagged Bitcoin volatility exhibits Granger-causal effects on the vol…
