Household Savings and Negative Interest Rates

This paper analyses determinants of household savings in a model based on an extension of the disequilibrium savings theory. These extensions follow from the life-cycle, permanent-income and Ricardian-equivalence theories. Based on panel data of 20 countries from the period 2000–2020, fixed-effect least squares estimation procedures are used. The analysis provides evidence that negative interest rates lead to a statistically and economic significant increase in savings. This implies that stimulating household consumption with a monetary policy of negative interest rates is counter-productive. The positive effect of income uncertainty and lagged saving rates gets smaller for negative interest rates, weakening the support for the disequilibrium-savings theory. Larger government deficits increase savings even more when rates are negative, strengthening the Ricardian equivalence effect. The effect of negative interest on the predictions of the life-cycle and permanent-income theories is mixed.

Fiscal Stabilization in the United States: Lessons for Monetary Unions

The debate about the use of fiscal instruments for macroeconomic stabilization has regained prominence in the aftermath of the Great Recession, and its relevance has suddenly increased further, after the recent Covid-19 shock. The analysis of fiscal stabilization in the United States, a monetary union equipped with a common fiscal capacity, has often informed the literature on the European EMU and could serve as a reference for its possible future reforms. This paper expands that literature in three ways: first, by measuring stabilization not only as inter-state risk-sharing of asymmetric shocks, but also as intertemporal stabilization of common shocks;second, by doing this for specific items in the US federal budget, both on the revenue and on the expenditure side;and third, by also measuring the impact of the federal system of unemployment benefits and of its extension as a response to the Great Recession. Corporate and personal income tax, on the revenue side, and social security benefits and federal grants, on the spending side, are the most effective items. The US federal system of unemployment insurance provides great stabilization in the event of a large shock, in particular when enhanced by the discretionary program of extended benefits. These findings imply that a proper design of the budget can maximize its stabilization effect, when it helps bridging the gap between higher mobility of capital and lower mobility of labor, by collecting revenues based on the income of the most mobile factor (corporate income tax) and providing support to the income of the least mobile factor (social security).

Sukuk and bond dynamics in relation to exchange rate

PurposeThis study aims to contribute by expanding the existing literature on Sukuk return and volatility and exploring the implications of the Sukuk-exchange rate interactions. Design/methodology/approachThis study examines the dynamic interactions of Sukuk with exchange rate in 15 countries, employing the Wavelet approach that considers both time and investment horizons. FindingsThe results reveal significant evolving coherence of Sukuk return and volatility with the underlying exchange rate. The relationship is more potent than what this study witnesses in their counterpart bond market. For Sukuk returns, the coherence is negative, whereas it is positive for volatility. Notably, the coherence is strong in the medium to long term and intensifies during extreme economic episodes, especially during the COVID-19 pandemic. These findings are further validated by comparing firm-level matched data for Sukuk and conventional bond. Originality/valueTo the best of the authors' knowledge, this is the first study that reports the dynamic relationship of Sukuk return and volatility with the underlying exchange rate in 15 countries. Collectively, this study unites valuable insights for faith-based active Islamic investors and cross-border portfolio managers.

Slowbalisation in the Context of US-China Decoupling

While it is too early to confirm the depth and the sustainability of this new trend towards slower globalisation, it may be happening in more domains than we are fully aware of, at least for the near term given the renewed backdrop of the Russia-Ukraine war and the wider use of sanctions globally.
