Household food waste is considered to be the largest share of food waste along the food supply chain. Given that its recoverability is also more challenging compared to food waste in other stages of the chain, most studies on household food waste adopt a pre‐emptive approach by aiming to identify and address consumer beliefs, attitudes and actions that are linked to food waste. In scientific literature, household food waste has often been studied in relation to the habit of purchasing discounted food products (DFP). However, findings have been contradictory. Specifically, while some authors found that deal‐prone consumers are usually of lower income and therefore display a wiser and more attentive attitude towards grocery shopping, other authors reported that the purchase of discounted products was usually linked to compulsive shopping, hence resulting in higher food waste quantities at home. Due to these discrepant findings, a definitive answer on the impact of DFP on household food waste does not currently exist in the literature. This paper analyses the correlation between the purchase of DFP and weekly household food waste quantities. To do so, we examine (a) the results of a food waste diary experiment carried out on a representative sample of 385 households in Italy in February 2017, and (b) the results of a 23‐items Computer Assisted Web Interview survey administered to the same householders, in which shopping habits were investigated. Results revealed no evidence of either a positive or negative relationship between the purchase of DFP and household food waste quantities. Frequency of grocery shopping was the only variable found to have a significant impact on household food waste quantities. 相似文献

We study the cause of large fluctuations in prices on the London Stock Exchange. This is done at the microscopic level of individual events, where an event is the placement or cancellation of an order to buy or sell. We show that price fluctuations caused by individual market orders are essentially independent of the volume of orders. Instead, large price fluctuations are driven by liquidity fluctuations, variations in the market's ability to absorb new orders. Even for the most liquid stocks there can be substantial gaps in the order book, corresponding to a block of adjacent price levels containing no quotes. When such a gap exists next to the best price, a new order can remove the best quote, triggering a large midpoint price change. Thus, the distribution of large price changes merely reflects the distribution of gaps in the limit order book. This is a finite size effect, caused by the granularity of order flow: in a market where participants place many small orders uniformly across prices, such large price fluctuations would not happen. We show that this also explains price fluctuations on longer timescales. In addition, we present results suggesting that the risk profile varies from stock to stock, and is not universal: lightly traded stocks tend to have more extreme risks. 相似文献

This article analyses the role of deviations from higher level collective agreements adopted in firm-level bargaining to regain higher labour mobility, net positive employment effects and a resurgence of labour productivity. Using Italian firm-level data, after performing preliminary pooled ordinary least squares and fixed effects estimates, we adopt a difference-in-difference approach combined with a propensity score matching. All the estimations show that opting out clauses notably increases both hiring and separations, but without significant variations in terms of net employment. In addition, no significant labour productivity gains are obtained. The only significant change concerns the increase in the share of temporary workers. 相似文献

Exploring different views of exchange rate regime choice 总被引:1,自引:0,他引:1

The empirical distinction between de facto and de jure exchange rate regimes raises a number of interesting questions. Which factors may induce a de facto peg? Why do countries enforce a peg but do not announce it? Why do countries “break their promises”? We show that a stable socio-political environment and an efficient political decision-making process are a necessary prerequisite for choosing a peg and sticking to it, challenging the view that sees the exchange rate as a commitment device. Policymakers seem rather concerned with regime sustainability in the face of adverse economic and socio-political fundamentals. 相似文献

The paper studies the motivations behind banks’ shareholding of non-financial firms using a panel of large Italian companies in the period 1994–2000. Empirical evidence shows that banks are shareholders of companies that are less profitable, have experienced slower growth, are more indebted, are endowed with collateral and have hard time to repay their debt out of current income. Banks are more likely to hold shares in companies they lend to. Overall the evidence suggests that there is complementarity between bank equity holding and lending. A plausible explanation is the shareholder–debtholder conflict, the evidence is weakly compatible with governance and information hypotheses. 相似文献

This article provides an introduction to the special issue of the Review of Economic Dynamics on “Cross-Sectional Facts for Macroeconomists”. The issue documents, for nine countries, the level and the evolution, over time and over the life cycle, of several dimensions of economic inequality, including wages, labor earnings, income, consumption, and wealth. After describing the motivation and the common methodology underlying this empirical project, we discuss selected results, with an emphasis on cross-country comparisons. Most, but not all, countries experienced substantial increases in wages and earnings inequality, over the last three decades. While the trend in the skill premium differed widely across countries, the experience premium rose and the gender premium fell virtually everywhere. At a higher frequency, earnings inequality appears to be strongly counter-cyclical. In all countries, government redistribution through taxes and transfers reduced the level, the trend and the cyclical fluctuations in income inequality. The rise in income inequality was stronger at the bottom of the distribution. Consumption inequality increased less than disposable income inequality, and tracked the latter much more closely at the top than at the bottom of the distribution. Measuring the age-profile of inequality is challenging because of the interplay of time and cohort effects. 相似文献

In this paper we present a stylised framework of fiscal policy determination that considers both structural targets and cyclical
factors. We find significant cyclical asymmetry in the behaviour of fiscal variables in a sample of fourteen EU countries
over 1970–2007, with budgetary balances (both overall and primary) deteriorating in contractions without correspondingly improving
in expansions. Analysis of budget components reveals that cyclical asymmetry comes from expenditure. We find no evidence that
fiscal rules introduced in 1992 with the Treaty of Maastricht affected the cyclical behaviour of fiscal variables. Numerical
simulations show that cyclical asymmetry inflated average deficit levels, contributing significantly to debt accumulation. 相似文献
