The duration of business cycle expansions and contractions: are there change-points in duration dependence?

The business cycles literature shows that the likelihood of an expansion or contraction ending increases with its age, i.e. they exhibit positive duration dependence. This evidence rests on the assumption that the magnitude of duration dependence is the same over time. However, we assume that the degree of likeliness of an expansion or contraction ending as it gets older might indeed change after a specific duration. Estimating a continuous-time Weibull model for a group of 13 industrial countries over the period 1948–2009 and allowing for the presence of a change-point in the duration-dependence parameter; we conclude that the evidence of positive duration dependence is no longer present when an expansion surpasses 10 years of duration.     

The Portuguese business cycle: chronology and duration dependence

This paper tries to identify a chronology for the Portuguese business cycle and test for the presence of duration dependence in the respective phases of expansion and contraction. A duration-dependent Markov-switching vector autoregressive model is employed in that task. This model is estimated over year-on-year growth rates of a set of relevant economic indicators, namely industrial production, a composite leading indicator and, additionally, civilian employment. The estimated specifications allow us to identify four main periods of contraction during the last three decades and some evidence of positive duration dependence in contractions, but not in expansions, especially when employment is added to the model.     

Duration of sudden stop spells: A hazard model approach

Using a hazard‐based duration model, we analyze the determinants of the duration of a period of sudden stop, which is defined as a drop in capital inflow by two standard deviations, for at least two consecutive quarters. The hazard model estimates the conditional probability that the country exits the sudden stop today given that it experienced one until the end of last period. We find that a higher ratio of foreign exchange reserves to short‐term external debt shortens the duration of sudden stops. We also find that a higher global economic growth rate tends to shorten sudden stop spells. Our results are robust to various alternative specifications.     

A further note on the three phases of the US business cycle

Using a number of alternative approaches, Sichel (1994) demonstrated evidence supporting the notion that the US business cycle is best characterized as having three distinct phases, viz. contraction, followed by rapid expansion during the early stages of the recovery phase, followed by a period of more normal expansionary growth, with the cycle then repeating itself. This contrasts with the more usual expansion/contraction, two phase characterization but is more in keeping with the original notion of the business cycle as conceived by Burns and Mitchell (1946). Here an alternative approach is employed for shedding light on this issue. Following the original suggestion of Hamilton (1989, 1990, 1991), a simple nonlinear, three phase, regime switching Markov model is compared against its simpler two phase version to determine which version is statistically more consistent with the business cycle historical evidence. The evidence seems to clearly support the three phase characterization and that this characterization yields interesting information on business cycle dynamics which is necessarily missed by the two phase model formulation.     

State dependent asymmetric loss and the consensus forecast of real U.S. GDP growth

It has been well documented that the consensus forecast from surveys of professional forecasters shows a bias that varies over time. In this paper, we examine whether this bias may be due to forecasters having an asymmetric loss function. In contrast to previous research, we account for the time variation in the bias by making the loss function depend on the state of the economy. The asymmetry parameter in the loss function is specified to depend on set state variables which may cause forecaster to intentionally bias their forecasts. We consider both the Lin–Ex and asymmetric power loss functions. For the commonly used Lin–Ex and Lin–Lin loss functions, we show the model can be easily estimated by least squares. We apply our methodology to the consensus forecast of real U.S. GDP growth from the Survey of Professional Forecasters. We find that forecast uncertainty has an asymmetric effect on the asymmetry parameter in the loss function dependent upon whether the economy is in expansion or contraction. When the economy is in expansion, forecaster uncertainty is related to an overprediction in the median forecast of real GDP growth. In contrast, when the economy is in contraction, forecaster uncertainty is related to an underprediction in the median forecast of real GDP growth. Our results are robust to the particular loss function that is employed in the analysis.     

The business cycle of capitalism

In every business expansion the wage share declines because productivity rises faster than hourly wages. As a result, towards the end of expansion the limited wages and salaries cause an insufficient growth of consumer demand, which makes it difficult to realize profits. At the same time costs - including wage costs, material costs and interest costs - are rising, so it is difficult to produce at a profit. Therefore, at the peak of the cycle rising costs and insufficient demand squeeze profits as in a nutcracker, causing a fall in the expected rate of profit, which leads to a business contraction. In every business contraction the opposite trends tend to produce eventual recovery and a new expansion.     

Internal migration and youth entrepreneurship in the Democratic Republic of the Congo

This paper analyzes youth internal migration in the Democratic Republic of the Congo (DRC) and its impact on entrepreneurship startup in a fresh post‐conflict context. Building on a national representative survey conducted in 2005, a recursive bivariate probit specification is used to jointly estimate the decision models of both migration and entrepreneurship. To evaluate the robustness of results, the propensity score matching method is used to test the concordance of the results after eliminating the redundant impact of unobserved factors. The two main conclusions are that youth migration increases the probability of being an entrepreneur, but in the informal sector. In addition, like secondary and post‐secondary education, the duration of stay after migrating is an important factor to being an entrepreneur in the formal sector. These conclusions are expected to enlighten policy‐makers as to the importance of promoting secondary and post‐secondary education as well as inclusive growth investments that may absorb more youth labor in formal sectors. This is the first exercise in the case of the DRC and since it focuses on youth, the paper makes a unique contribution to the literature related to the link between migration and entrepreneurship in a post‐war context.     

The Quality Ladder and Product Variety: Larger Economies May Not Grow Faster

This paper constructs an endogenous growth model that combines the quality ladder model and the variety expansion model. Firms enter an imitation race. After the imitation process, monopolistic competition prevails and a new innovation race begins. A successful firm, by inventing a higher quality product, can take over the entire market. However, the existence of a variety of products limits the price that the successful firm can charge. We show that the present model exhibits an inverted U-shape relationship between market size and growth rate. Relatively large and small economies grow slowly while medium-sized economies grow rapidly.     

Growth and Output Fluctuations

This paper sheds new light on the interaction between growth and output fluctuations. Our approach is different from the literature in that we analyse how endogenous fluctuations are affected by a faster productivity growth in the long run. Main results: (i) expansion (or contraction) occurs more (or less) frequently, (ii) expansion becomes milder but contraction severer, (iii) the amplitude of fluctuations becomes larger, (iv) the variance of output changes ambiguously, indicating a non-monotonic relationship. We also investigate how an R&D subsidy alters the nature of output fluctuations and re-examine its effect on technological change in the presence of recurrent cycles. The result questions the widely-accepted theoretical implication that a research subsidy unambiguously promotes technological progress.     

Government size and economic growth in an endogenous growth model with rent‐seeking

We explore the relationship between government size and economic growth in an endogenous growth model with human capital and an unproductive capital which facilitates rent‐seeking. With exogenous as well as endogenous time discounting, we find a non‐monotonic relationship between the size of government and economic growth. We find that with very high (low) discounting, there is a unique low (high) growth equilibrium, regardless of the size of government. For the intermediate range of discounting, there are multiple equilibria and the growth outcome depends on the size of government. With endogenous time discounting, the growth outcome is path dependent and depends on the level of inherited human capital. However, there is only one stable growth regime and the economy endogenously switches to it. When the institutional constraints on rent‐seeking are not extremely high, the stable regime is the one in which there is a high‐growth equilibrium for a smaller size of the government and for larger size, both the high‐growth and the low‐growth equilibrium coexist. When the institutional constraints on rent‐seeking are extremely high, there exists only a unique high‐growth equilibrium irrespective of the size of government. Furthermore, economies with bigger size of the government and/or with poor quality institutions will take longer to endogenously switch to this stable growth regime.     

Hiring Older Employees: Do the Age Limits of Early Retirement and the Contribution Rates of Firms Matter?

We examine the effects of a Finnish pension reform on firms' incentives to hire older employees. The reform restricted the eligibility ages for early retirement and changed the size‐related contribution rates of firms. According to our theoretical model, the positive effect on the values of new hires extends to age groups younger than those directly affected by the reform, and the effects are strongest in the largest firms. These model predictions were confirmed in a difference‐in‐difference‐in‐differences analysis on the probability of the hiring of workers of different ages in firms of different sizes.     

Trade‐led growth hypothesis in Cuban commercial regimes since 19601,2

This study examines the impact of trade on Cuban growth during different commercial policy regimes spanning the period from 1960 up to 2004, encompassing two essential economic structural transformations: the Cuban revolution and the fall of the Berlin Wall. For this purpose, the Granger causality is used by means of the modified Wald test for augmented‐level vector autoregressive model with integrated and cointegrated processes introduced by Toda and Yamamoto (1995) and Dolado and Lutekepohl (1996) . We show an import‐led growth hypothesis during the Soviet‐oriented pattern that is rejected after 1990, when exports are not only responsive to growth expansion but also to imports’ behaviour.     

Asymmetry and Duration Dependence in Australian GDP and Unemployment

The periodic structure of business cycles suggests that significant asymmetries are present over different phases of the cycle. This paper uses markov regime-switching models with fixed and duration dependent trasition probabilities to directly model expansions, contractions and durations in Australian GDP growth and unemployment growth. Evidence is found of significant asymmetry in growth rates across expansions and contractions for both series. GDP contractions exhibit duration dependence implying that as output recessions age the likelihood of switching into an expansion phase increases. Unemployment growth does not exhibit duration dependence in either phase. Evidence is also presented that non-linearities in unemployment growth are well explained by the asymmetries in the GDP growth cycle. The analysis suggests that recessions are periods of rapid and intense job destruction, that Australian unemployment tends to ratchet up in recessionary periods and, in contrast to US and UK studies, that shocks to Australian unemployment growth are more persistent in recessions than expansions.     

Growth Cycles and Market Crashes

Market booms are often followed by dramatic falls. To explain this requires an asymmetry in the underlying shocks. A straightforward model of technological progress generates asymmetries that are also the source of growth cycles. Assuming a representative consumer, we show that the stock market generally rises, punctuated by occasional dramatic falls. With high risk aversion, bad news causes dramatic increases in prices. Bad news does not correspond to a contraction of existing production possibilities, but to a slowdown in its expansion. This economy provides a model of endogenous growth cycles in which recoveries and recessions are dictated by the adoption of innovations.

The Role of Human Capital and Population Growth in R&D‐based Models of Economic Growth*

Human capital accumulation is introduced in a growth model with R&D‐driven expansion in variety and quality of intermediate goods and knowledge spillovers from both research activities. Economic growth is no longer uniquely tied to population growth as previous growth models without scale effects suggest. The model predicts that economic growth depends positively on the rate of human capital accumulation and positively or negatively on population growth and is therefore supported by empirical evidence to a greater extent than previous models. In particular, long‐run growth is compatible with a stable population.     

An economic theory of leadership turnover

In an infinite-horizon stochastic model, a coup not only disciplines a dictator's policy towards a group of “kingmakers”, but also enables a kingmaker to become a dictator. Greater competition for the dictator's position, a lower impact of the dictator's policy on the kingmakers, or lower risks of staging a coup raises the benefit of a coup relative to its opportunity cost and so raises the probability of a coup. Since periodic shocks affect the efficacy of the dictator's policy, a bad enough shock makes it too costly for even talented dictators to avert a coup. More talented dictators are able to survive more negative shocks, so the worst shock in a dictator's reign is informative about the probability of a coup. Conditional on the worst shock, the probability of a coup is independent of a dictator's duration in office. The unconditional probability declines with duration.     

Effects of the Chinese arable land fallow system and land-use change on agricultural production and on the economy

This study focuses on economic effects of arable land fallow system and land-use change in China using a dynamic single-country, multi-regional computable general equilibrium model. Land supply is adjusted endogenously in our model. Land use in each of 31 provinces is tracked by a land-use change module, which is calibrated with satellite data. Our results reveal that the expansion of real output can be attributed to the increase in capital stock as a result of the growth of investment due to the imposition of the arable land fallow system in China. And the growth of investment is caused by the release of labor from agriculture The reduced supply of arable land in agricultural land contraction regions is partially offset by the increasing arable land in agricultural land expansion regions. Rural households benefit more than urban households from the arable land fallow policy due to relatively higher income and lower rural CPI.     

Regime‐dependent effects of uncertainty on inflation and output growth: evidence from the United Kingdom and the United States

Employing a bivariate regime switching model, this paper attempts to examine the regime‐dependent effects of inflation uncertainty and output growth uncertainty on inflation and output growth. Using monthly data of the United Kingdom and the United States, we provide evidence that both nominal and real uncertainty exert regime‐dependent impacts on inflation. Furthermore, in case of both the countries, inflation uncertainty has adverse impact on output growth mainly during the period of economic contraction. Also, for these two countries, it can be argued that higher real uncertainty significantly reduces output growth only in their respective low output growth regimes.     

ANALYSIS OF THE POSSIBILITIES FOR EXPANSION OF SERVICES IN TANZANIAN SAVINGS AND CREDITS CO‐OPERATIVE SOCIETIES: LEARNING FROM ECONOMIES OF SCALE

Savings and Credit Co‐operative Societies (SACCOS) increasingly recognized as the valuable tool for economic development in low‐income countries. However, recently researchers reported that one of their primary challenges to their expansion is the high level of inefficient. In this study, we analyzed the relationship between growth and efficiency of SACCOS using economies of scale concept. Then we address the role of management of the capital structure and allocation of resources in the expansion of SACCOS. The study used financial statement data from 60 SACCOS in Tanzania for the period of 2004–2011. The findings supports that most of SACCOS are small and cost inefficient because the industry is young, but, the efficiency increases as SACCOS expand. Second the allocation of resources in liquid, financial and non‐financial investment leads to no expansion in SACCOS. Thus, the growth of SACCOS via increasing loan to members, members’ savings, shares, and institutional capital should be encouraged as it increases the efficiency of SACCOS. Also, SACCOS should minimize the allocation of assets in other investments which are different from credit to members.     

Endogenous Trade Policies in a Developing Economy

This paper examines the formation of trade policy for a small open developing economy where lobbying activities may be carried out to influence policy‐making decisions. The paper presents a three‐sector economy in which the manufacturing sector can lobby policymakers for favorable policies. Under some plausible conditions, it is demonstrated that lobbying activities carried out by the owners of the specific factor in the manufacturing sector would secure a protectionist trade policy through either an import tariff or an export subsidy. The government also imposes a consumption tax on agricultural products, which further strengthens the protectionist measure applied to the manufacturing sector. In general equilibrium, there will be a movement of labor to the manufacturing sector, an output expansion in the manufacturing sector, and an output contraction in the agricultural sector, exactly as suggested by factual evidence.
