Oil volatility and the option value of waiting: An analysis of the G‐7

There has recently been considerable interest in the potential adverse effects associated with excessive uncertainty in energy futures markets. Theoretical models of investment under uncertainty predict that increased uncertainty will tend to induce firms to delay production and investment. These models are widely utilized in capital budgeting and production decisions, particularly in the energy sector. There is relatively little empirical evidence, however, on whether such channels have effects on industrial production. Using a sample of G7 countries we examine whether uncertainty about a prominent commodity—oil—affects the time series variation in industrial production. Our primary result is consistent with the predictions of real options theory—uncertainty about oil prices has had a negative and significant effect on manufacturing activity in Canada, France, UK, and US. © 2010 Wiley Periodicals, Inc.

The Impact of Perceived Expectations and Uncertainty on Firm Investment

This paper analyses the (differential) impact of perceived expectations and uncertainty on investment spending in small and large firms. We analyse two types of investment, viz. aggregate investment and investment in energy-saving technologies, using Dutch firm level data. The results show that expectations and uncertainty about input- and output prices and domestic demand have substantial but different effects on investment spending in firms of different sizes. Furthermore, we find evidence, at least for small firms, that there are important differences between the effects of uncertainty about input and output variables.     

Greenfield FDI,cross-border M&As,and government size

This study examines the effects of greenfield foreign direct investment (FDI) and cross-border mergers and acquisitions (M&As) on government size in host countries of FDI. Using panel data for up to 130 countries for the period from 2003 to 2011, the study specifically tests the compensation hypothesis, suggesting that by increasing economic insecurity, economic openness leads to larger government size. It is found that greenfield FDI increases labour market volatility and thereby economic insecurity while M&As are not significantly associated with labour market volatility. The main results of this study are that greenfield FDI has a robust positive effect on government size, while M&As have no statistically significant effect on government size in the total sample of developed and developing countries, as well as in the sub-samples of developed and developing countries.     

Low‐Frequency Volatility of Yen Interest Rate Swap Market in Relation to Macroeconomic Risk*

Using ‘low‐frequency’ volatility extracted from aggregate volatility shocks in interest rate swap (hereafter, IRS) market, this paper investigates whether Japanese yen IRS volatility can be explained by macroeconomic risks. The analysis suggests that this low‐frequency yen IRS volatility has strong and positive association with most of the macroeconomic risk proxies (e.g., volatility of consumer price index, industrial production volatility, foreign exchange volatility, slope of the term structure and money supply) with the exception of the unemployment rate, which is negatively related to IRS volatility. This finding is fairly consistent with the argument that the greater the macroeconomic risk the greater is the use of derivative instruments to hedge or speculate. The relationship between the macroeconomic risks and IRS volatility varies slightly across the different swap maturities but is robust to alternative volatility specifications. This linkage between swap market and macroeconomy has practical implications since market makers and hedgers use the swap rate as benchmark for pricing long‐term interest rates, corporate bonds and various other securities.     

INTERNATIONAL PRODUCTION,INVESTMENT AND BORROWING WITH EXCHANGE RATE RISK AND FUTURES MARKETS

In this paper we consider a multinational firm under exchange rate and interest rate risks in a multiperiod model. We analyze the impact of exchange rate uncertainty and the use of currency futures on the risk-averse firm's decisions about home and foreign production. Without any hedging markets exchange rate risk lowers foreign investment and output. However, when futures markets exist, the separation property holds. Introducing another source of uncertainty, such as the interest rate, which is nondiversifiable, affects the production in both countries, i.e., the separation property does not hold. However, we show that the adverse effect of the missing financial market (to hedge against this additional risk) disappears when international borrowing is available.     

Dynamic Agency and Investment Theory under Model Uncertainty

We extend dynamic agency and investment theory by incorporating model uncertainty. As concerns regarding model uncertainty induce a trade‐off between incentives and ambiguity sharing, the principal tends to delay the cash payout to the agent. We find model uncertainty lowers the firm value, the average q and marginal q, where q is defined as the ratio between a physical asset's market value and its replacement value. Furthermore, model uncertainty leads to insufficient investment, which provides an alternative explanation for under‐investment. Finally, the optimal pay‐performance sensitivity of the agent's continuation value to the firm's output is state dependent and exceeds the lower bound when it is close to the payout boundary.     

Dollarization,Inflation Targeting,and Inflationary Dynamics in Ghana

ABSTRACT

The impact of dollarization on domestic economic performance, and the welfare implications of high inflation in an inflation targeting environment, have remained a matter of much concern for policymakers in recent years. This study investigates the effects of dollarization on inflation and inflation uncertainty in Ghana for the period January 1990 to December 2017. We apply the exponential Generalized Autoregressive Conditional Heteroskedasticity model together with impulse response and Granger causality tests to explore how dollarization affects the behavior of inflation for the pre-inflation targeting period (January 1990 – May 2007) and post-inflation targeting period (June 2007 – December 2017). The results indicate that dollarization has not played a significant role in the volatility of inflation in Ghana. Also, inflation Granger causes dollarization in both the pre- and post-inflation targeting regimes. Finally, there is a bidirectional causal relationship between inflation and inflation uncertainty following the adoption of inflation targeting monetary policy. We conclude that, although inflation targeting has not presented a significant impact on inflation volatility, it has affected the relationship between inflation and inflation uncertainty in Ghana. The dynamics of inflation volatility and asymmetries present crucial implications which are discussed to guide policymaking.     

Real call options to enlarge foreign subsidiaries – The moderating effect of irreversibility on the influence of economic volatility and political instability on subsequent FDI

This paper develops a real option model to explain the decision of enlarging a new foreign subsidiary by subsequent investment. The model is tested on a panel of 1148 subsidiaries in 22 host countries. The findings complement the traditional process model of firm internationalization. Rather than abiding by an incremental pattern of investment, internationalizing firms seem to keep foreign investment strategies flexible and build up their subsidiaries contingent upon the interaction of economic volatility and irreversibility of investment. However, the moderating effect of irreversibility on the relationship between uncertainty and investment may not hold for downside risks such as political instability.

Real Exchange Rate Targeting,Macroeconomic Performance and Sectoral Income Distribution in Developing Countries

This paper uses a two-sector general equilibrium model to analyse both steady-state and stochastic dynamic effects of two real exchange rate targeting policies: a constant-target, and a band-target rule. In the model, targeting is implemented by imposing a stochastic fully-rebatable tax on the consumption of non-traded goods. The first result is that when comparing only steady states, a real exchange rate appreciation favours labour and capital in the non-traded sector, while factors in the traded sector are favoured by depreciations. A second result is that both rules reduce the volatility of investment and the trade balance. The third key result is that in the stochastic economy sectoral income distribution outcomes depend on the design of the constant and band-target rules. In particular, a variety of outcomes may be generated depending on the magnitude of the constant target, or the amplitude of the band, relative to the volatility of productivity shocks.     

Herding behaviour in an emerging market: Evidence from the Moscow Exchange

This study investigates the extent to which herding towards the market consensus for Russian stocks is driven by fundamental and non-fundamental factors. We find evidence that investors on the Moscow Exchange herd without any reference to fundamentals during unanticipated financial crises coupled with high uncertainty, in falling markets, and during days with extreme upward oil price movements. In contrast, in periods of high liquidity and on days of international sanction announcements during the Ukrainian crisis, herding behaviour is merely driven by fundamentals. In Russia, macroeconomic news releases induce both information-related herding and herding without any reference to fundamentals. These results suggest that motives of investors' herding behaviour vary under specific market conditions such as market trends, liquidity, uncertainty, arrival of new information, and oil price volatility.     

Immigration,uncertainty and macroeconomic dynamics

This paper examines the macroeconomic effects of rising migration uncertainty in four advanced economies (i.e. US, UK, Germany and France). Migration uncertainty is first captured by the Migration Policy Uncertainty (MPUI) and the Migration Fear (MFI) news-based indexes developed by Baker et al. (Immigration fears and policy uncertainty, 2015), and then by a novel Google Trend Migration Uncertainty Index (GTMU) based on the frequency of Internet searches for the term ‘immigration’. VAR investigations suggest that the macroeconomic implications of rising migration uncertainty differ across countries. Moreover, news-based and Google search-based migration fear shocks generate different macroeconomic effects. For instance, in the US (France), MPUI, MFI and GTMU shocks all improve (undermine) production and labour market conditions in the medium run. For Germany and the UK, mixed evidence is found, suggesting that increasing media attention on migration phenomena and rising population's interest in migration-related issues influence people's mood differently. The observed heterogeneity in the macroeconomic effects of rising migration uncertainty can be explained by cross-country gaps in (a) the level of labour market rigidity, (b) the degree of people's happiness and life satisfaction and (c) the percentage of graduates.     

FOREIGN EXCHANGE RATES AND FOREIGN DIRECT INVESTMENT IN THE UNITED STATES

The hypothesis that foreign direct investment into the United States responds to variations in exchange-rate levels and to exchange-rate uncertainty is tested for the period 1976-1998. We account for nonstationarity and cointegration in the data series and use conditional measures of exchange-rate uncertainty. While a long-run relationship exists among foreign direct investment in-flows as a share of GNP, the real exchange rate, and the GARCH measure of exchange-rate volatility, we find no discernible link between the real exchange rate and inward foreign direct investment in the short run. We also conclude that foreign direct investment decreases in response to increases in exchange-rate uncertainty in the short run when we use a conditional measure of exchange-rate uncertainty.     

International real business cycles with endogenous markup variability

The aggregate impact of decisions made at the level of the individual firm has recently attracted a lot of attention in both the macro and trade literatures. We adapt the benchmark international real business cycle model to a game-theoretic environment to add a channel for the strategic interaction among domestic and foreign firms. We show how the sum of strategic pricing decisions made at the level of the individual firm can have significant effects on the volatility and cross country co-movement of GDP and its components. Specifically we show that the addition of this one channel for strategic interaction leads to a significant increase in the cross-country co-movement of production and investment, as well as a significant decrease in the volatility of investment and the trade balance over the benchmark IRBC model.

Trade openness, investment instability and terms-of-trade volatility

In the presence of economies of scale in the investment technology, trade openness may have non-conventional effects on the level of investment, its cyclical behavior, and the volatility of the terms of trade. Trade openness may lead to boom-bust cycles of investment supported by self-fulfilling expectations. The economy may oscillate between ‘optimistic’ expectations, ‘good’ terms-of-trade and investment boom to ‘pessimistic’ expectations, ‘bad’ terms-of-trade and investment bust. We also suggest that the likelihood of such oscillations is higher for developing than for developed economies, because the former may typically incur higher setup costs of investment. This phenomenon may help to explain the excessive volatility of the terms of trade of developing countries, relative to industrial countries.     

DYNAMIC CDO TERM STRUCTURE MODELING

This paper provides a unifying approach for valuing contingent claims on a portfolio of credits, such as collateralized debt obligations (CDOs). We introduce the defaultable (T, x) ‐bonds, which pay one if the aggregated loss process in the underlying pool of the CDO has not exceeded x at maturity T, and zero else. Necessary and sufficient conditions on the stochastic term structure movements for the absence of arbitrage are given. Background market risk as well as feedback contagion effects of the loss process are taken into account. Moreover, we show that any exogenous specification of the volatility and contagion parameters actually yields a unique consistent loss process and thus an arbitrage‐free family of (T, x) ‐bond prices. For the sake of analytical and computational efficiency we then develop a tractable class of doubly stochastic affine term structure models.     

Fear Linkages Between the US and BRICS Stock Markets: A Frequency-Domain Causality

Abstract

We employ a spectral causality approach to uncover short-, medium-, and long-run causal relations between the US implied volatility index and the five individual implied volatility indexes of BRICS markets from 16^th March 2011 to 31^st January 2018. We show that the volatility causal relations differ between the short and long run in many cases. Although the results indicate the dominant role played by US uncertainty in shaping uncertainty in all BRICS markets, there is also evidence of a feedback effect from Brazil, Russia, and China to the US that differs across the spectrum. The implications for hedging and risk management practices are explored.     

Real options and the theory of foreign direct investment

We extend applications of real options theory to foreign direct investment (FDI) research regarding choice of location and choice of market entry mode under uncertainty. Our study is motivated by the regional configuration of multinational enterprises (MNEs), as well as observed deviations from the stages model in internationalization theory. We shed light on these issues using real option modeling and computer simulations. The results suggest that from the standpoint of pursuing business opportunities and generating real options, building a subsidiary in a nonhome region could be more beneficial than in a home region. However, high option exercise cost may reduce the option value of a nonhome-region location. Our models also imply that choice of entry mode depends on the magnitude (high vs. low) and the type (exogenous vs. endogenous) of uncertainty. When uncertainty is high and endogenous, MNEs may prefer high-commitment entry modes because they contribute to the reduction of uncertainty and provide valuable growth options.     

Future rent-seeking and current public savings

The conventional wisdom is that politicians' rent-seeking motives increase public debt and deficits. This is because myopic politicians face political risk and prefer to extract political rents as early as possible. In this paper we study the determination of government debt and deficits in a dynamic political economy model. We show that this conventional wisdom relies on economic volatility being low relative to political uncertainty. If economic volatility is high relative to political uncertainty, then a rent-seeking government actually over-saves and over-taxes along the equilibrium path relative to a benevolent government. This result emerges because of the option value of rent-seeking: a rent-seeking government over-values future funds because of the possibility of using them for future rents instead of cutting taxes in the event of a future boom (when marginal utility of private consumption is low). This over-saving bias is temporary since, in the long run, the rent-seeking government over-borrows relative to the benevolent government as it eventually squanders the funds it has accumulated. We find that both the under-saving and over-saving bias of the government can be solved by a rule of capping deficits.
