Why does the peso-dollar exchange rate show a depreciation trend? The role of productivity differentials

Over the last three decades, Mexico's macroeconomic policy has been driven by a sound orthodox strategy: an open economy via many trade agreements signed since the mid-1980s, a nominal exchange rate under a flexible regime since 1994, central bank autonomy, and responsible fiscal policy, among other benchmarks. Nevertheless, the exchange rate has continued on a path of depreciation against the US dollar. In this paper, we show that although an equilibrium relationship exists between the exchange rate and prices in Mexico and the US (its main commercial partner), there are other forces affecting the former. The main factor in this relentless long-term depreciation is the loss of productivity in Mexico relative to the US. In addition, we show that the extraordinary liquidity supplied by the US during the 2008 crisis caused the Mexican peso to appreciate against the dollar.     

Sticky Price Models,Durable Goods,and Real Wage Rigidities

The standard two‐sector New Keynesian model with durable goods is at odds with conventional wisdom and vector autoregression (VAR) evidence: Following a monetary shock, the model generates (i) either negative or no comovement across sectoral outputs and (ii) aggregate neutrality of money when durable goods' prices are flexible. We reconcile theory with evidence by incorporating real wage rigidities into the standard model: As long as durable goods' prices are more flexible than nondurable goods' prices, we obtain positive sectoral comovement and, thus, aggregate nonneutrality of money.     

The “Euro Illusion”: Illusion or Fact?

The changeover to the euro elicited an upsurge of research on the effects of the new currency on consumers’ conversion strategies, price estimates, price evaluations, choices, and purchases. This research includes longitudinal surveys, interviews, and controlled experiments, both natural and in the laboratory. The present article starts with an overview of this research after which it more specifically focuses on research showing an influence of the nominal value, as expressed in different currencies, on price evaluations and consumer choice. For most countries, the transition to the euro led to a lower nominal value currency. A bias known as the “euro illusion” has been documented such that the subjective value of money is influenced in the direction of the nominal value (i.e., in most countries prices and salaries seem smaller when expressed in euros than in the old domestic currency). Although the term was coined in connection with the euro changeover, the nominal representation of a currency has been shown to influence the subjective value of money in unfamiliar currencies other than the euro. Thus, tourists travelling abroad may frequently be subject to such an illusion. Different mechanisms have been proposed to account for the euro illusion. One is the numerosity heuristic and another the anchoring-and-adjustment heuristic in conjunction with biased conversion strategies. The size of the euro illusion is influenced by trade-offs between accuracy and effort. Consistent with this hypothesis, task importance, time constraints, familiarity with the conversion strategy, complexity of the conversion strategy, mood, and attitude towards the country or the currency all influence the size of the euro illusion.     

中美贸易顺差与人民币汇率关系的实证分析

针对中美贸易顺差与人民币汇率关系的问题,本文通过协整分析和Granger因果检验发现,人民币升值在短期难以对中美贸易顺差产生调节作用,从长期影响而言,人民币升值的影响作用也不大。此外,中美贸易顺差在短期还是主要取决于当前贸易收支的现实情况,而中长期则在很大程度上受到美国经济波动的影响。因此,人民币升值不会缓解美国巨大的贸易逆差,而且即使美国贸易收支出现改善也不会对美国经济发展产生显著的正面影响。     

Where is the GE? Consumption Dynamics in DSGEs

We offer a partial equilibrium perspective on the behavior of consumption in dynamic stochastic general equilibrium (DSGE) models. We consider a benchmark dynamic general equilibrium model and show that a standard calibration implies that the real interest rate is essentially fixed. One manifestation of this feature is that, with separable preferences, the reaction of consumption to total factor productivity (TFP) shocks is flat: the random‐walk permanent income hypothesis holds almost exactly, pretty much as in a partial equilibrium consumption‐savings problem. These results help explain the prominent role of aggregate demand, and how it is achieved, in modern DSGE analysis.     

Does easing monetary policy increase financial instability?

This paper develops a model featuring both a macroeconomic and a financial friction that speaks to the interaction between monetary and macro-prudential policy and to the role of US monetary and regulatory policy in the run up to the Subprime mortgage crisis. There are two main results. First, interest rate rigidities in a monopolistic banking system increase the probability of a financial crisis (relative to the case of flexible interest rate) in response to contractionary shocks to the economy, while they act as automatic macro-prudential stabilizers in response to expansionary shocks. Second, when the interest rate is the only available instrument, monetary policy faces a trade-off between macroeconomic and financial stability. This trade off is both qualitative and quantitative in response to contractionary shocks, while it is only quantitative in response to positive shocks. We show that a second instrument, such as a Pigouvian tax on credit to households on the demand side of the market, is needed to restore efficiency in the economy when both frictions are at work.     

Facilitating public participation in tourism planning on American Indian reservations: A case study involving the Nominal Group Technique

Tourism is frequently cited as a tool by which American Indians can strengthen the economies of their reservations. However, successful tourism development on such reservations requires effective tourism planning, and effective tourism planning requires public participation in the planning process. The Nominal Group Technique (NGT) has proved to be a useful group process in the tourism field but its application to tourism planning on American Indian reservations has been unexplored. This article helps to fill this knowledge gap by reporting on an NGT workshop conducted on the Lake Traverse Reservation of the Sisseton–Wahpeton Oyate (people, nation) in North and South Dakota, USA. Rich information on tourism development possibilities for three lakefront properties was obtained. Possible success factors are discussed and suggestions for conducting similar future workshops on American Indian reservations are advanced.     

ExpertLens: A system for eliciting opinions from a large pool of non-collocated experts with diverse knowledge

The complexity of policy decision-making raises the need to elicit opinions from large and heterogeneous groups of stakeholders with broad and diverse sets of expertise. Existing options for elicitation include small face-to-face panels of experts by using the Nominal Group Technique (NGT), large Delphi panels whose members do not interact with each other face-to-face, and crowdsourcing, which involves an open call for input issued to a large community of people. In an attempt to close the gap between the practical needs of policy makers and the methodological challenges associated with eliciting opinions of large, diverse, and distributed groups, we have developed a new online elicitation system and methodology called ExpertLens. By optimizing the direct interactions of NGT with the larger number of Delphi participants and the wisdom of “selected crowds,” our approach is designed to save on the costs associated with traditional expert panels, while increasing accuracy in elicitation by reducing the potential for group process losses that can occur in large, diverse, and non-collocated panels whose members interact via asynchronous online discussion boards. The ExpertLens approach is iterative, does not require participants to develop consensus, and determines what the group “thinks” by statistically analyzing data collected in all rounds of the elicitation. This paper describes the ExpertLens system and methodology, briefly discusses recent ExpertLens trials, provides conceptual arguments for why it is an appropriate model for eliciting expert opinions, illustrates its main components and analytics by using an infrastructure investment example, and discusses a research agenda for testing the underlying tenets of the ExpertLens approach.     

Comparative Advantage Indices of Selected Livestock Production Sectors in Brunei Darussalam

Abstract

This study calculates the protection rates and comparative advantage indices of livestock industry in Brunei from an import substitution perspective. Four livestock sub-sectors were being evaluated: broiler, layer, goat and beef cattle. Two measures of government intervention indices were calculated, namely nominal protection rate (NPR) and effective protection rate (EPR). Domestic resource cost (DRC) and resource cost ratio (RCR) indices were computed to determine the comparative advantages of the livestock industry. In general, the results indicate that the livestock industry in Brunei was heavily protected. The study revealed the existence of comparative advantage only for very large farms producing poultry meat and eggs. Similarly in the ruminant sector, goat production appears to have comparative advantage over beef cattle. Small and medium poultry farms and large non-ruminant farms and cattle beef production possess comparative disadvantage despite being highly protected industries.
