Like father like son? Revisiting the role of parental education in estimating returns to education in China

Parental education has been used as an instrument in the earnings equation to deal with the endogeneity problem of education. Recently, however, many have found that parental education can be a proxy for unobservable networking, which directly affects wages. This article revisits the role of parental education in estimating returns to education by introducing the “geographical isolation” theory. For migrant workers who receive an education and move around to work, parental education affects their education but otherwise is unrelated to their wages, which makes parental education a good instrument in the instrumental variable approach. For local residents who stay in the same place during childhood and adulthood, parental education can directly affect their wages, and is better introduced as a proxy variable using the control variable method. This article identifies the heterogeneous effect of parental education on wages for different Chinese cohorts and contributes to the debate between the control variable and instrumental variable methods in returns to education studies. Moreover, the idea of geographic isolation can help in the search for good instrumental variables for migrant workers, which is valuable when studying the large migrant population in developing countries such as Mexico, China, India, Vietnam, and many African countries.     

A note on the endogeneity of the price of utility within the consumer’s static profit function

Currently, the consumer’s price of utility, which is integral to the consumer’s or Frischian static profit function, is viewed as exogenous to the profit-maximization decision. The present note challenges this perspective by demonstrating that if the consumer is a profit maximizer, then the consumer’s price of utility is endogenous to the decision-making process.     

A note on the ‘Linsanity’ of measuring the relative efficiency of National Basketball Association guards

This note examines the productive efficiency of 62 starting guards during the 2011/12 National Basketball Association (NBA) season. This period coincides with the phenomenal and largely unanticipated performance of New York Knicks’ starting point guard Jeremy Lin and the attendant public and media hype known as Linsanity. We employ a data envelopment analysis (DEA) approach that includes allowance for an undesirable output, here turnovers per game, with the desirable outputs of points, rebounds, assists, steals and blocks per game and an input of minutes per game. The results indicate that depending upon the specification, between 29% and 42% of NBA guards are fully efficient, including Jeremy Lin, with a mean inefficiency of 3.7% and 19.2%. However, while Jeremy Lin is technically efficient, he seldom serves as a benchmark for inefficient players, at least when compared with established players such as Chris Paul and Dwayne Wade. This suggests the uniqueness of Jeremy Lin's productive solution and may explain why his unique style of play, encompassing individual brilliance, unselfish play and team leadership, is of such broad public appeal.     

A note on the exchange market pressure: the Korean experience, 1980–1987

This paper applies the exchange market pressure (EMP) model to Korea under a managed floating exchange rate. We show that the EMP model is superior to one concentrating solely on foreign reserve or exchange rate changes. Given that the balance of paymnets in Korea experienced a drastic turn to surplus during the estimated period, we checked the stability of the coefficients. The results show that the coefficients have remained stable.     

Does the aggregate production function imply anything about the laws of production? A note on the Simon and Shaikh critiques

The aggregate production function (especially the Cobb–Douglas) is widely used in both applied and theoretical work, in spite of the large number of criticisms of it that have been advanced since its inception. Two related criticisms by Simon and Levy (1963) and Shaikh (1974) are particularly damaing since they have shown that if factor shares are stableanyunderlying technology will generate a Cobb–Douglas relationship. This argument seems to have been largely ignored in the literature or, by implication, not seen as particularly important. The purpose of this paper is to assess and extend these criticisms. New empirical evidence is presented which, it is argued, illustrates the former. Furthermore, it is shown that a Kaleckian mark-up model will equally give rise to a Cobb–Douglas even though, of course, no neoclassical assumptions are invoked. It is concluded that the Cobb–Douglasper se can give no independent corroboration of either the marginal productivity theory of distribution or the assumption of perfect competition.     

Does the constraint matter? A note on the asymptotic properties of nonparametric instrumental variable estimation under monotonicity shape constraint

I show that constrained monotone instrumental variable estimators are asymptotically equivalent to their unconstrained counterparts whenever the true regression function is in the interior of the constrained set. In a simulation study, a sieve-based constrained estimator is shown to outperform the unconstrained one even in cases where both are asymptotically equivalent.     

Should central bankers discount the future? A note

Optimal monetary policy under discretion is analysed in a New Keynesian model with rule of thumb pricing. The paper finds that social welfare increases if the policy maker does not discount the future. The welfare improvement rises with the extent of intrinsic inflation persistence.     

What enhances mathematical ability? A cross-country analysis based on test scores of 15-year-olds

This article examines the mathematical abilities of 15-year-olds in a range of countries which participated in the 2003 cycle of the Organization for Economic Cooperation and Development (OCED)'s Programme for International Student Assessment (PISA). Utilizing information on the scores obtained by individual students in the mathematical part of the PISA assessment, we use a range of indicators from the literature on inequality and poverty to evaluate the ‘mathematical performance’ of participating countries. Since data from PISA contained a wealth of information on the circumstances of the students in terms of their home and school environment, we identify and examine the relative influence of factors which serve to enhance the mathematical performance of students in the PISA assessment.     

A note on “Rethinking liquidity creation: Banks,shadow banks and the elasticity of finance”

Abstract

In their recent article, Yeva Nersisyan and Flavia Dantas proposed to amend the endogenous money theory to account for the activity of nonbank financial institutions (NBFIs) and of foreign banks. It is indeed argued that the traditional post Keynesian and circuitist approaches are overly narrow because they rely on a limited definition of money. Consequently, these approaches are focused on commercial banks (that create money) and regard other financial institutions as mere intermediaries that intermediate funds from surplus units (savers) toward deficit units (borrowers). Because it treats NBFIs as mere intermediaries, the authors argue that the traditional post Keynesian framework is no longer relevant for the analysis of the contemporary financial system. We believe that this critique is not justified. Using balance sheet analysis, we show that the destabilizing role of NBFIs can be taken into account within the traditional post-Keynesian framework.     

Money,reserves, and the transmission of monetary policy: Does the money multiplier exist?

With the use of non-traditional policy tools, the level of reserve balances has risen in the US from roughly $20 billion before the financial crisis to well past $1 trillion. The effect of reserve balances in macroeconomic models often comes through the money multiplier, affecting the money supply and the bank lending. In this paper, we document that the mechanism does not work through the standard multiplier model or the bank lending channel. If the level of reserve balances is expected to have an impact on the economy, it seems unlikely that a standard multiplier story will explain the effect.     

A replication note on unemployment in the OECD since the 1960s: what do we know?

Nickell et al. (Econ J 115(500):1–27, 2005) argue that unemployment rates cointegrate with labour market institutions in a panel of OECD countries. This paper replicates their Maddala–Wu panel cointegration test and shows that this test is only valid when (i) the number of countries tends to infinity and (ii) the underlying country-specific cointegration tests are independent. Their finding of cointegration does not survive when small sample properties and heterogeneous cross-sectional dependencies are taken into account.

Would you like to shrink the welfare state? A survey of European citizens

The fundamental problems facing European welfare states – high unemployment and unsustainable public pensions plans in particular – have been in the political debate for years, so why have we seen so little reform? To find out, we surveyed the opinions of citizens in France, Germany, Italy and Spain on their welfare states and on various reform options. This is what we found. First, most workers underestimate the costs of public pensions, though they are aware of their unsustainability. Second, the status quo is a majoritarian outcome: a majority of citizens opposes cuts to social security and welfare spending, but also opposes further increases. Since population ageing without reform implies an automatic expansion, our results suggest that most citizens would favour reforms that stabilize but do not shrink the current welfare states. Third, many would welcome changes in the allocation of benefits. A large number of workers in Italy and Germany would be willing to opt out of public pensions and replace them with private pensions, though the details of how this scheme is formulated matter for its popularity. And many Italians and Spaniards would welcome an extension of the coverage of unemployment insurance. Fourth, conflicts over the welfare state are mainly shaped by the economic situation of the respondent, while political ideology plays a limited role. Disagreements are found along three dimensions: young versus old, rich versus poor, and 'outsider' versus 'insider' in terms of labour market status. From a practical point of view, this suggests that there is scope to bundle reforms strategically in order to build a large and mixed coalition of supporters.

How important is cultural background for the level of intergenerational mobility?

Based on brother correlations in permanent earnings for different groups of second generation immigrants, the findings in this paper indicate that cultural background is not a major determinant of the level of intergenerational economic mobility.     

Is there an energy paradox in fuel economy? A note on the role of consumer heterogeneity and sorting bias

From the previous literature, it can be found that consumers tend to undervalue discounted future energy costs in their purchase decisions for energy-using durables. We show that this finding could, in part, result from ignoring consumer heterogeneity in empirical analyses as opposed to true undervaluation.     

Does wealth inequality affect the transmission of monetary policy?

We provide evidence that higher wealth inequality between households is associated with stronger real effects of monetary policy. First, we use state-dependent local projections to show that the US and the UK exhibited stronger real effects of monetary policy in times of higher wealth inequality. Second, we measure wealth inequality within US states and document that economic activity responds more strongly to interest rate changes in states where wealth is distributed more unequally. Third, we show that ECB monetary policy has stronger real effects in Euro Area countries with higher wealth inequality.     

A comment on ‘the small country assumption: a note on Canadian export’

Some simple statistical tests of efficiency are applied to limited diversification portfolios that are optimal in terms of minimizing risk measured by variances. These tests are intended to detect in some sense robustness, near-singularity and improvement of a portfolio by revision. The illustrative application considers eleven securities selected randomly from Moody's Handbook over the years 1970–81     

Which pasture is really greener? A research note on salary studies

National and regional studies of nurse salaries often draw conclusions based solely on the dollar values reported. This brief research note shows the importance of including information about the cost of living into any comparative analysis of geographic differences in salaries.     

Global banking,global crises? The role of the bank balance-sheet channel for the transmission of financial crises

We examine whether shocks to leveraged creditors with cross border holdings have an incidence on debtor countries׳ risk of suffering financial turmoil. We construct a new proxy of shocks to international banks׳ balance-sheets using credit ratings and the structure of their international assets. This allows us investigating the effect of (foreign) bank balance-sheet shocks on domestic financial turmoil in a large sample of 146 developed and emerging economies from 1984 to 2011. Our proxies of shocks towards bank balance-sheets are strong predictors of systemic banking crises in their debtor countries. Confirming these results, bilateral bank flows significantly decrease when creditor banks׳ assets are hit by negative shocks, as measured by credit rating downgrades from third-party countries. Short-term liabilities towards global banks appear to increase roll-over and funding risks, thereby amplifying the impact of shocks to foreign lenders’ balance-sheets. Domestic banking sectors vulnerabilities, such as illiquid assets and a low deposit-asset ratio, are found to increase crisis contagion risk. In contrast, a high level of global liquidity attenuates the transmission of shocks to international banks׳ assets to debtor countries.     

“A profit table or a profit calculator?” A note on the design of Cournot oligopoly experiments

We report on an experiment conducted to evaluate the effects of varying the way in which market information is presented to participants in laboratory Cournot duopolies. We find that the most standard variations, which are the use of a profit table or a profit calculator, yield indistinguishable performance. However, the addition of a best-response option to the profit calculator tends to increase aggregate output to the Cournot level and decrease the incidence of tacit collusion.
